Abstract:

Abuse of opioids and other prescription controlled substances is a recognized nation-wide problem in United States and around the globe. Emerging FDA guidelines are setting up the ground rules for related evaluation and product labeling. As these documents point out, science of abuse deterrence is relatively new, and both the formulation technologies and the analytical, clinical, and statistical methods for evaluating those technologies are rapidly evolving. This presentation will focus on the overview of the existing and novel formulation approaches to enable tamper-resistant properties to include approaches involving physical/chemical barriers, agonist/antagonist combinations, aversion, delivery, and prodrug. Neither of the approaches can provide absolute protection and eliminate all the illicit options. So the question is, if there are clear pathways is assessing suitability of an appropriate technology for a given drug candidate or product and evaluating their readiness to be deployed. Up to date only a handful of tamper-resistant technological solution advanced far enough to be implemented into the market product. This number will certainly increase in near future as nascent and established tamper-resistant formulations will be further tested in clinical trials and interrogated by FDA.

Abstract:

Hepatocellular carcinoma (HCC) is the second most common cause of cancerrelated death worldwide. The prognosis of patients with HCC is usually poor; hence, a novel approach against HCC is essential for a better therapeutic outcome. Saffron and its active constituents were reported to have antioxidant, anti-inflammatory, and anti-tumor properties. The aim of this study was to investigate chemopreventive action of crocin, one of the promising active constituents of saffron, against diethylnitrosamine (DEN)- induced liver cancer in rats, and the possible mechanisms by which crocin exerts its antitumor effects. Findings reported herein demonstrated the anti-proliferative and proapoptotic properties of crocin when administrated in DEN-treated rats. Additionally, crocin exhibited anti-inflammatory properties that inhibited NF-kB, among other inflammatory markers. According to our network analysis, NF-kB was identified as a regulatory hub, and therefore, a candidate therapeutic drug target. Together, these findings nominates crocin as a candidate chemopreventive and therapeutic agent against HCC.

Abstract:

Niacin and lovastatin are cholesterol lowering drugs. Niacin synthesized from tryptophan belongs to BCS class 1 with pKa 2.17 and plasma t1/2 20-48 min. Lovastatin naturally occurring in oyster mushrooms was isolated from Aspergillus terreus in 1982 and derived from red yeast rice in 1998. It is classified as BCS class 2 with pKa 13.49 andt1/2 4.5h. This presentation aims (1) to review lovastatin production using submerged culture vs. solid state fermentation of Aspergillus terreus and various chemically defined media, (2) toelucidate the fabrication ofa two-layer tablet design containing 250 mg niacin and 20 mg lovastatin, (3) to describe the formulation of a 20 mg lovastatin mini tablet in the delayed-then-extended dissolution release manner (without niacin). For aim 1, five literatures will be summarized. For aim 2, niacin heated with carnauba wax and stearic acid to blend. Once cooled, the solid mixture was tritulated with Carbomer 940 NF, Methocel K4M CR, sodium starch glucolate and Kollidone VA 64 to compress into a caplet. Ground mixture of lovastatin (the second drug), magnesium stearate, SDS and Avicel PH100 were added on top of niacin caplet to compress into the second layer. For aim 3, beta-cyclodextrin was complexed with lovastin (1:1 molar ratio) in hydroalcoholic solution. Once evaporated dried, this powder added with other excipients was compressed into mini tablets containing 20 mg lovastatin each. These cores were further enteric coated with a dispersion of Eudragit L 30D-55 and water (1:1 v/v). Content assay and in vitro release samples were quantified by HPLC.DSC confirmed no interaction between lovastatin and excipients. This project recommends that niacin (a rather acidic very water soluble small molecule) and lovastatin (an acid labile poorly water soluble macromolecule) be formulated separately.

Abstract:

Skin is a significant barrier for the penetration of hydrophilic drugs. Generally, chemical permeation enhancers have been utilized in the dermal and transdermal systems to enhance the delivery of drugs. However, use of chemical permeation enhancers is associated with several disadvantages. Particularly, enhancers such as glycols, terpenes, surfactants, solvents such as alcohol and DMSO have been found to cause dermal irritation and more severe side effects on prolonged use. Therefore, there is huge demand for safer and economical methods of drug permeation enhancement across the skin. The existing biophysical technologies such as iontophoresis, sonophoresis, microneedles, electroporation and laser ablation methods are known to perturb the skin barrier which would take considerable amount of time to recover. Some of the technologies are not patient compliant either. A technology that enhances the delivery of drugs across the skin without affecting the skin structure and barrier properties is required in the present scenario. Magnetically mediated enhancement of drugs is a novel and simple approach to enhance the transdermal delivery of drugs. The magnetic field could be generated by placing simple permanent magnets on the drug reservoir or as a backing membrane in magnetic field. In this presentation, the use of magnetic field in the transdermal patch system and its efficacy as compared to chemical enhancers will be discussed.The development of patch system in addition to the data of in vitro permeation test and pharmacokinetic studies in human subjects will be presented.

Abstract:

Treatment of hypertension has reduced the incidence of stroke, heart and renal failure. However the incidence of Coronary Heart Disease (CHD) is not reduced to the same degree. Many of the drugs advocated as first line drugs in step-wise therapy has been shown to cause carbohydrate intolerance, and it is an independent risk factor in the development of CHD. Since 1990’s individualized therapy in the treatment of hypertension has been advocated, whereby another class of antihypertensive drugs, such as calcium channel blockers (dihydropyridines) may be used as a first line therapy. Intracellular calcium plays important role in the excitation contraction coupling as well as the excitation-secretion coupling of hormones, including insulin. Absolute and relative lack of insulin can cause glucose intolerance. The purpose of the study was, to compare the effect of calcium channel blockers on insulin release from the rat isolated pancreas by perfusion technique, adapted from Loubatieries et al., 1972. The doses used were based on therapeutic peak plasma concentrations. Diazoxide has been used as positive control, i.e. known insulin suppressant drug. In the study Isradipine (10ng/ml) and Nicardipine (200ng/ml) showed significant suppression of the insulin release, this effect is dose dependent. Amlodipine (5ng/ml) significantly did not suppress the insulin release. Thus Amoldipine is found more useful drug amongst other calcium channel blocker. In conclusion different calcium channel blockers have varying effects on insulin release.

Abstract:

The objective of this study is to prepare vaginal suppository containing chemotherapeutic agent and genetic material that can be applied locally in cervical cancer which is the second most frequently observed cancer type in women below the age of 45 and is generally resistant to chemotherapy. Paclitaxel has been selected as chemotherapeutic agent and siRNA that inhibits the BCL-2 oncogene has been selected as the genetic material. SLNs have been formulated in order to load the paclitaxel and siRNA to the vaginal suppository and to compare their effects. Paclitaxel loaded SLN, siRNA loaded SLN and paclitaxel/siRNA loaded SLNs have been dispersed separately in vaginal suppository prepared with PEG 6000. First, the physicochemical properties of SLNs, their cytotoxicities as well as the effects of siRNA loaded SLN on the protein amount expressed by the BCL-2 gene in the cells have been examined. Afterwards, the release of SLNs from the three different vaginal suppositories prepared has been determined via Horizontal Diffusion Chamber System. The paclitaxel amount loaded to the SLNs has been determined via HPLC whereas the siRNA amount has been determined via gel retardation system and UV spectrophotometer.

Abstract:

Acute Lymphoblastic Leukemia (ALL) is a hematopoietic cancer predominant in children and involves many aberrant pathways. There is a need to identify novel targets to improve our understanding of disease biology and for developing new therapeutics. Hence, the aim of our study was to uncover new genes as targets using in silico approaches. We first analyzed Oncomine micro array database to profile the top 10% overexpressed genes of significance. These were then prioritized using ENDEAVOUR, DIR and TOPPGene online tools to identify novel candidate disease genes. Thirty training genes, overexpressed in ALL were retrieved from PubMed literature search to train the tools. Further, the functional association networking of the prioritized and training genes was investigated using STRING protein interaction database. The network was then analysed using cytoHubba tool to identify highly connected hub genes. From our analysis of Oncomine database, 530 genes were shortlisted which on prioritization revealed fifty four genes to be significant candidate leukemogenic genes. Our hub analysis of the protein network led to identification of two novel genes, SMAD2 and CDK9, which were not implicated in leukemogenesis earlier. Filtering out from several hundred genes in the network we also found MEN1, HDAC1 and LCK genes to be important hubs, which re-emphasized their important role in leukemogenesis. This is the first report on these five additional signature genes in leukemogenesis. Our findings suggest that these genes could serve as new targets for developing novel therapeutics and also as biomarkers in leukemogenesis, which could be important for prognosis and diagnosis.

Abstract:

Graphene Oxide (GO), a close derivative of graphene has unlocked many pivotal steps in drug delivery due to their inherent biocompatibility, heavy drug loading capacity and high aqueous solubility. We used a novel plant material called Gum Arabic (GA) to increase the solubility of GO as well as to chemically reduce it in the solution. GA functionalized GO (fGO) exhibited increased absorption in Near Infra-Red Region (NIR) which was exploited in photothermal therapy for cancer. To augment the shape and size related problems of GO (which in turn affect their rheological properties), we have conjugated them with gold nano-rods (GNRs) using in situ synthesis of GO@GNRs via seed mediated method. To the above conjugate, Doxorubicin (DOX) was attached at ambient temperature (28±2 °C). Release kinetics of DOX with and without NIR exposure was also studied followed by in vitro photothermal killing of A549 cell lines. Enhanced NIR induced drug release as well photothermal property was observed which makes fGO@GNRs-DOX ideal for chemotherapy as well as photothermal therapy.

Abstract:

Chromatin is the major regulator of gene expression and genome maintenance. Proteins that bind the nucleosome, the repetitive unit of chromatin, and the histone H4 tail are critical to establishing chromatin architecture and phenotypic outcomes. To modulate the chromatin structure, we designed a Nucleosome Binding Peptide – GMIP1- based on the crystal structure of RCC1 protein bound to a mononucleosome (PDB 3MVD). Molecular dynamic showed that GMIP1 tend to form an alpha helix, which suggests a more stable structure. For binding assays, we reconstituted mononucleosomes in vitro with 601 DNA -167pb- and histone octamer purified from chicken erythrocytes. The binding of fluorescent-labeled GMIP1 to a mononucleosome was observed by EMSA. To verify the GMIP1 effect in vivo, we performed MTT assays with different cell lines, such as Hela, Raw and skin fibroblast (CCD 1059). We observed a significant reduction of cells viability and proliferation with 50 uM of GMIP. In order to analyze the role of GMIP1 on the inflammatory pathway, we performed real-time PCR of TNF-alpha RNA extract from Raw cells. GMIP1 strongly reduced TNF-alpha expression and completely inhibited TNF-alpha stimulation by LPS, reducing fivefold the gene expression compared to non-treated cells. New experiments are on the way to check the peptide binding to nucleosome in cell based assays. Herein we present an exogenous Nucleosome binding molecule, a peptide, with intrinsic properties to modulate chromatin architecture and phenotypic outcome.
