Abstract:

The process of drug development is extremely time consuming and costly. It takes approximately 10-12 years and costs hundreds of millions or billions dollars. Pharmacometrics is the scientific discipline that uses mathematical models based on biology, pharmacology, physiology, and disease for quantifying the interactions between drugs and patients. Its purpose is to reduce cost and shorten development time by optimizing the clinical assessment of efficacy and safety. This presentation highlights the value of pharmacometric analyses in drug development through selected examples.

He continues to specialize in bringing therapeutic options for neglected diseases and vulnerable populations.

Abstract:

Nowadays it is rare to see any FDA submission package without a Pharmacokinetics/Pharmacodynamics modeling component where some clinical trials were designed based on simulation. The current workflow is that an expert modeler provide model outputs and simulation about scenarios that he thinks are important to emulate future trials and decisions. Then, the decision maker might then ask for new more relevant scenarios to the current situation. This decision process is iterative where one simulated scenario might warrant another question/scenario that need to be tested until we reach a satisfactory decision. As such this involves sveral cycles of back and forth. All this results in bottlenecks cycles where the decision maker is waiting for simualtion results and where simulation scientists are waiting for decision maker to give them more scenarios to test. Why is this ? The simulation workflow is so complicated that only the person who built the underlying models and simulation scenarios can get useful answers. However, recent technological advances has enabled simulation scientists to build specialized user interfaces that enable decision makers to be part of the design team and ask questions and get answers on the fly. Today this is possible using web based responsive user interface A successful simulation exercice involve a mathematical modeler (e.g.pharmacometrician), a clinical trial expert, a therapeutic area expert (or a clinician) a computational/web developer expert and the clinical development decision maker. An example of the development of such an app for Tuberculosis will be demoed.

Abstract:

Dolabella auricularia, also known as sea hare, is a marine gastropod that it found in the waters of Indo – Pacific. The aims of this research were to explore the potential of nutritional content of the species and in vitro anti-diabetic activity of sea hare extract. The composition of fatty acid was measured by gas chromatography, amino acids were measured by high performance liquid chromatography and mineral was measured by atomic absorption spectrophotometer. In vitro anti-diabetic activity of the sea hare extracts was evaluated by measuring their inhibitory effect on alpha-glucosidase level. The sea hare contained nine essential amino acids and six non-essential amino acids. Total saturated fatty acids was at 5.33% (g /100g), MUFA at 2.11% (g/ 100g), PUFA at 4.1% (g/100g). Calcium was at 68100 mg/kg, potassium at 10000 mg/kg, sodium at 8200 mg/kg, and carbohydrate at 1.52%. Sea hare ethyl acetate extract has in vitro anti-diabetic activity better than methanolic extract. The ethyl acetate extracts inhibited alpha-glocosidase activity in vitro, in a concentration dependent manner (IC50=25.76 mg/mL). The present study confirms that sea hare had a rich source of nutritional and their inhibitory effects on alpha-glucosidase.

Abstract:

Rhodocodon campanulatus is a member of the bulbous Urgineeae tribe of the Scilloideae subfamily of the expanded Asparagaceae family (formerly Hyacinthaceae). Plants of the Urgineeae tribe are used as traditional remedies for the treatment of several ailments, such as infections, rheumatism, inflammation and disorders associated with the central nervous system. The Urgineeae tribe is distributed from South Africa to the Mediterranean, Saudi Arabia, India and Myanmar. The chemical constituents of plants of the Rhodocodon genus are not documented and hence the plant was investigated for chemo-taxonomical reasons. In this study we report the isolation of a novel bufadienolide glycoside and a known homo-isoflavonoid from the ethanol extract of the bulbs of Rhodocodon campanulatus. The major compounds were novel bufadienolide glycoside, 1, 3β-(O-β-D-glucopyranoside)- 14β-hydroxybufa-20,22-dienolid-19-al, and the known homo isoflavonoid, 2, 5,7-dihydroxy-3-(3-hydroxy-4-methoxybenzyl) chroman-4-one, previously isolated from the South African Scilla kraussi. The structures of 1 and (2, 2a-b) (figure 1) were determined by the analysis of their NMR and MS spectra. The absolute configuration at C-3 for 2 was determined in this study as S on the basis of its electronic circular dichroism study. A positive Cotton effect at 290 was in agreement to those reported for homo isoflavonoid with H-3 in β position. Compound 1 was screened against NCI60 cancer cell lines and did not show any significant growth inhibition. Compound 2-2a-b was tested for anti-angiogenic inhibition ability. Compound 2b was found to be effective against the angiogenesis of human retinal micro vascular endothelial cells (HRECs) with GI50 values of 128 μM. Recent Publications 1.

Abstract:

Background: Pharmaco-genetics is an important branch of pharmacology and should be applied to assist the clinical usage of medicines which has a strong relation with enzyme activity of certain genes and alleles known through the literature. CYP2C19 is known to affect the activity of omeprazole and this will result in different responses to treatment. The commonest alleles through the literature are CYP2C19*2 and CYP2C19*3 which vary according to different ethnicity of different populations. Methodology: A purposeful convenient sampling; in which patients with peptic ulcer disease and treated with omeprazole were reviewed and the PCR is used to differentiate the CYP2C19 different alleles in patients presenting from February 2016 to January 2017. Results: In the present study we investigated the distribution of three common gene variants affecting the omeprazole treatment of peptic ulcer disease and H. pylori eradication namely to CYP2C19*2, *3 and *7. The CYP2C19*2 mutation was found among all seven ethnic groups of Sudan, Arabs mostly 17 (139) followed by Darfurians 9 (139), Beja 6 (139) and Nilotes 6 (139), Nuba 5 (139) then Nubians 3 (139) and Fulani 1 (139), p=0.048 which is significant. Regarding CYP2C19*3 mutation of this allele is found in certain ethnic groups Arabs 6 (139), Nubians 6 (139) and Nuba 2 (139), p=0.043 significant. There is no mutation found among different Sudanese ethnic groups in CYP2C19*7. Arabs are normal homozygotes 6 (139) and Darfurians 1 (139). Nuba 1 (139) was found to be heterozygotes in this allele p=0.038 significant. Treatment of H. pylori with omeprazole-based triple therapy was used in 110 (139) and no significant correlation found with the different ethnic groups of Sudan. Conclusion: These data indicate that Sudanese seven ethnic groups showed activity of CYP2C19*2, CYP2C19*3 were they took omeprazole based triple treatment and some of them showed activity to CYP2C19*7.

Abstract:

Generally the gelatin used in pharmaceutical and food dosage form was obtained from bovine and porcine. This research explored the new alternative source of gelatin, namely goat skin. Goat skin was soaked in hydrochlorid acid and then gelatin was extracted using warm water. Their physicochemical and pharmaceutical properties were investigated. A yield of 12.74±0.87 g/100 g skin sample on the basis of wet weight was obtained. Organoleptic of goat gelatin powder is a vitreous, brittle solid faintly yellow in color, nearly tasteless and odorless. The result of physicochemical properties exhibited the following: sulfide content of 7.18±0.68 ppm, lead, zinc and copper were not detected. % transmittance of goat gelatin solution revealed clarity value was 56.9±0.95. pH, moisture and ash content were 5.11±0.9, 9.23±0.9 and 0.18±0.16, respectively. The results of pharmaceutical properties including emulsion activity index, foaming properties, gel strength and viscosity were 77.23±23, 118.87±0.12, 307.67±2.64 and 25.5±1.83, respectively. The microbial assay showed microbes were not detected. All of these physicochemical and pharmaceutical properties of goat skin gelatin indicated that it meets the defined requirements of a good gelatin and could use as alternative material in pharmaceutical and food dosage form.

Abstract:

Parijoto (Medinilla speciosa Blume) is traditionally plant that used on diarrheal diseases, inflammation and cancer sores and potentially as anti-hyperlipidemia and anti-bacterial that have been tested in vivo and in vitro. Based on research, parijoto fruit contains secondary metabolites such as flavonoids, tannins, saponins and glycosides. The purpose of this study was to determine the anti-inflammatory activity of the ethanol extract parijoto by using Carrageenan-Induced Paw Edema method. Sprague Dawley rats were divided into five groups: Negative control (Na CMC 0.5% b/v), positive control (Diclofenac sodium 5.14 mg/kg BW), ethanol extract parijoto fruit in various doses of 100, 200 and 400 mg/kg body weight. The test substances are given orally before induction with 0.2 mL carrageenan 1%. Measuring of the volume of rat's paw is conducted every hour for five hours after carrageenan induction by using plethysmometer. The results showed that rats which were given ethanol extract of 100, 200 and 400 mg/kg BW have significantly different percentage of edema compared to the negative control group (p≤0.05). The percentage of edema inhibitions within the subjects group with doses of 100, 200 and 400 mg/kg BW are 74.58%, 72.88%, dan 50.85%, respectively. This result suggested that extract ethanol parijoto fruits are able to inhibit edema of rat’s paw which is indicated that this extract has a potency to be developed as the anti-inflammatory agent.

Biography:

Structure-based drug design has played significant role in the design of various drug candidates. The most studied targets include the HIV protease, dihydrofolate reductase, beta secretase etc. for which there are number of crystal structures available in the protein databases (pdb). Our drug discovery research group initiated the strategy of utilizing multiple crystal structures in the design of diverse ligands of human beta secretase and was successful. In continuation to our efforts in this field, we report here the discovery of diverse ligands for various therapeutic classes utilizing structure-based design for those proteins where more than hundred crystal structures were available in the pdb. We rationalized the selection of crystal structures bound with different ligands based on the resolution of the structure, no mutation and only the wild type. About nine to 10 crystal structures were employed in the structure-based drug design to develop energybased pharmacophore (e-pharmacophore) hypothesis based on the ligand interaction with the protein residues. Multiple e-pharmacophores were generated and validated using enrichment factor calculation. The validated pharmacophore hypothesis was utilized for filtering commercial database with pharmacophore fitness above 1.0. A high throughput screening combined with docking, analysis of binding amino acid residues and ADME parameters led to the identification of some potential diverse scaffolds that could be developed as novel inhibitors of HIV protease.

This study was aimed to develop simple, sensitive and accurate zero (0D), first (1D) and second (2D) order derivative spectrophotometric methods for the analysis of nicotinamide in bulk and dosage forms. Methods: The zero-order spectrum of nicotinamide aqueous solution was measured at 262 nm against its blank. This spectrum was differentiated instrumentally to generate the first and second derivative spectra which were measured at 272 nm and 278 nm, respectively. The developed methods were validated as per ICH guidelines.The absorbance ratio of nicotinamide absorbance values at 214 nm and 262 nm was also determined. Regression data of the developed methods obeyed Beer’s law over the concentration range 10-50 μg/ml with a good correlation coefficient (not less than 0.998). The developed methods demonstrated good inter-day and intra-day precision at the three modes. The obtained recovery percentage (99.2 ± 2.6%, n=3) reflected freedom from interference by the excipients. The absorbance ratio for nicotinamide at 214 nm and 262 nm was found to be in the range between 2.8- 3.2 which can be used as identification test for Nicotinamide (qualitative analysis). Conclusion: The statistical validation at 95% confidence level proved the sensitivity, accuracy and precision of the developed methods

Abstract:

Chronic pancreatitis is characterized by inflammation, fibrosis, and loss of exocrine (acinar cells) and endocrine (islets) tissue. In this study, L-arginine induced chronic pancreatitis model has been developed and the effect of Amar, an ayurvedic formulation on the chronic pancreatitis was studied in male Wistar rats. Animals were treated with vehicle control, Amar (25, 50 and 100 mg/kg/day) and methylprednisolone for a maximum period of 21 days and observed for general clinical parameters, clinical pathology parameters, anti-oxidant levels, inflammatory cytokines and pathological changes. oral (gavage) administration of Amar upto 100 mg/kg/day ameliorated the L-arginine induced changes in Chronic pancreatitis model in male Wistar rats. The treatment of Amar reduced the oxidative stress, the level of inflammatory cytokines levels and structural changes in pancreas. The results showed that antioxidant and anti-inflammatory properties of Amar could be the possible reason for its amelioration effect in L-arginine induced chronic pancreatitis model in male Wistar rats.

Abstract:

Since pharmacy is increasingly assuming the role of ‘primary and secondary health care professionals’, rather than being solely dispensers of medicines and suppliers of medical appliances, pharmacy students and researchers require new proficiencies as communicators, problem-solvers and advisers. ‘Social, behavioral and cognitive science’ has been identified as having a significant contribution to make in the educational training of pharmacists. In this lecture we are concerned specifically with the application of sociology to the practice of pharmacy. Social pharmacy is a file riven by social demands. By studying the relationship between pharmaceutical sciences, society and humanistic perspectives, particularly through case studies, the impact of medication and changes in societal expectation of them, as well as through historical background studies and surveys of current movement, this field acts to determine the roles of pharmacists and pharmacies expected by society. Social pharmacy requires a basic knowledge of pharmaceutical science, but an understanding from socio-economic viewpoints of the current status and structures in which healthcare functions is important as well. So far, social pharmacy has played a vital and necessary role in training curriculum for community-based pharmacists. Social pharmacy may be seen as including of all social indicators influencing the use of a particular drug, like drug-related beliefs, regulations, policy, knowledge, attitudes, practice, medicine information, ethics and behavior. Social pharmacy programs in pharmacy curricula are becoming more crucial and essential because of the various factors that can affect the health of a society. Social pharmacy deals with the study of community and human act and as a behavioral science is often related with disciplines that deal with individuals as well as large and small groups, including psychology, sociology and anthropology. So it can be discussed that social pharmacy begins with a rationale of social, cognitive and behavioral sciences to educational course for pharmacists and its inclusion in the curriculum and also establish of departments, centers and journals of social pharmacy, which is a prerequisite for the development of the concept of social pharmacy and its further implementation in real world evidence and practice.

Abstract:

Cancer is a major cause of death in developed countries, second aft er cardiac disease. In most of the cases, carcinogenesis is associated with chemical modifi cation of DNA. Th erefore, exogenous chemical carcinogens are indeed implicated in the aetiology of an increasing number of cancer types. Th e focus of the current contribution was to examine [6]-gingerol from ginger as a natural scavenger of nine ultimate chemical carcinogens: afl atoxin B1 exo-8,9-epoxide, β-propiolactone, 2-cyanoethylene oxide, ethylene oxide, chloroethylene oxide, glycidamide, propylene oxide, styrene oxide and vinyl carbamate epoxide. To evaluate [6]-gingerol effi ciency, we expanded our research with an examination of glutathione - the strongest endogenous scavenger of chemical carcinogens in human cells. Ab initio calculations of activation free energies were performed at the Hartree-Fock level of theory in conjunction with three fl exible basis sets. Our results obtained with implicit solvation imply that glutathione cannot effi ciently protect us from all studied chemical carcinogens, meaning that additional protection is required for prevention of chemical carcinogenesis. According to our results, [6]-gingerol proved to be a universal and extremely effi cient natural scavenger of all chemical carcinogens of the epoxy type. Th erefore, additional protection could
be assured by [6]-gingerol prophylaxis. Moreover, the obtained results present strong evidence in favor of the validity of the proposed SN2 reaction mechanism for the alkylation reactions of [6]-gingerol and glutathione with chemical carcinogens of the epoxy type and point to the applicability of quantum chemical methods to studies of early chemical carcinogenesis. Th e results of our study identifi ed a novel natural scavenger, namely [6]-gingerol, that could effi ciently prevent DNA alkylation damage by covalently binding to all studied ultimate carcinogens via a lower activation barrier. Th erefore, we strongly believe that this research represents the basis for further computational, experimental and clinical studies of anti-carcinogenic properties of [6]-gingerol and for development of novel selective dietary supplements.

Abstract:

Alzheimer’s disease (AD) currently is one of the major healthcare issues worldwide. Unfortunately current therapies for
Alzheimer’s disease do not modify the course of disease. Nigella sativa and its active constituent Th ymoquinone (TQ) may
have anti-neuro=-infl ammatory actions. Th e aim of the present study was to investigate possible protective eff ects of Nigella
sativa oil (NSO) and TQ on Aβ42-induced AD models of rats. Intrahippocampal injection of Aβ42 peptide provides glial cell
responses and causes neuro-infl ammation. NSO and TQ were orally administered daily for 7 days before and for 10 days
aft er bilateral intrahippocampal Aβ injection. To investigate whether NSO or TQ improve cognition, Passive Avoidance (PA)
and Morris Water Maze (MWM) behavioral tests were performed 10 days later Aβ injection to asses learning and memory
of rats. Aft er the probe test the brain tissues were collected. Immunohistochemical staining with Iba1, GFAP and Caspase-3
antibody and ELISA analysis of TNF-α and IL-1β levels on hippocampal tissue were performed. Th e oral treatment with
NSO or TQ signifi cantly reduced cognitive impairments in behavioral tests both MWM and PA. Immuno-staining results
revealed that both NSO and TQ reduced microglial and astrocytic activation increased with Aβ injection. Measurements of
pro-infl ammatory cytokines in hippocampal tissue of Aβ-injected rats showed an elevation of TNF-α and IL-1β levels. Th ese
changes were signifi cantly reversed by NSO and TQ treatment. In conclusion results represent that NSO and TQ can improve
Aβ-induced cognitive impairments by inhibiting neuro-infl ammation. NSO and TQ recommended as a candidate for further
investigation in treatment of AD.

Abstract:

The combination of modern electrochemical systems along with screen printing technology give an amazing chance for the introduction of potential and powerful analytical tools for efficient monitoring and analysis of pharmaceuticals, biomarkers and metabolites, environmental and food pollutants. Screen-printed electrodes (SPEs) can successfully address the time constraints associated with the conventional laboratory analysis. The adaptability and low-cost of this technology is accountable for its nonstop expansion and the continuous grow within the SPEs field to discover new areas of applications. Their improvements mainly will depend on incorporating new printed materials, new ligands, new polymers, further nanostructure materials and new supports. Recently, SPEs are coupled to biomolecules with the assistance of modern electroanalytical techniques and offers an excellent chance for therapeutic drug monitoring. In this work, detailed description of the elementary fabrication principles, the different designs of SPEs and the different analytical methods that are based on SPEs will be presented. Special emphasis is given on the electrochemical application of SPEs in pharmaceuticals analysis, their recent designs and the future perceptions.
