Oxadiazole moiety, which is one of the heterocyclic aromatic groups of the azole family; with the molecular formula C2H2N2O, exists in four isomeric form; out of which, 1,2,4-oxadiazole; 1,2,5-oxadiazole and 1,3,4-oxadiazole are common isomers. The stable isomeric forms of oxadiazoles are observed in a variety of pharmaceutical important potent drugs including raltegravir, butalamine, fasiplon, oxolamine and pleconaril. An attempt has been made to emphasize the chemistry and phar-macology associated with oxadiazole and its derivatives. A number of oxadiazole derivatives are very popular and common in use as potential therapeutic agents. However, a number of researchers are working and have worked to find out more synthetic analogues for anticancer and antifungal, anti-HIV agents using biological and in-silico models.

We present a novel series of HIV integrase inhibitors, showing IC50s ranging from 0.01 to over 370 muM in an enzymatic assay. Furthermore, pharmacophore modeling study for the inhibitors was carried out to elucidate the structure-activity relationships. Finally, we found a 3D-pharmacophore model, which is composed of a hydrophilic and a hydrophobic domain, providing valuable information for designing other novel types of integrase inhibitors.

Thiazolides are a novel class of anti-infectious agents against intestinal intracellular and extracellular protozoan parasites, bacteria, and viruses. While the parent compound nitazoxanide (NTZ; 2-(acetolyloxy)-N-(5-nitro-2- thiazolyl)benzamide) has potent antimicrobial activity, the bromo-thiazolide RM4819 (N-(5-bromothiazol-2-yl)-2-hydroxy-3-methylbenzamide) shows only reduced activity. Interestingly, both molecules are able to induce cell death in colon carcinoma cell lines, indicating that the molecular target in intestinal pathogens and in colon cancer cells is different. The detoxification enzyme glutathione S-transferase of class Pi 1 (GSTP1) is frequently overexpressed in various tumors, including colon carcinomas, and limits the efficacy of antitumor chemotherapeutic drugs due to its detoxifying activities. In colorectal tumor cells RM4819 has been shown to interact with GSTP1, and GSTP1 enzymatic activity is required for thiazolide-induced apoptosis. At present it is unclear which molecular structures of RM4819 are required to interact with GSTP1 and to induce cell death in colon carcinoma cell lines. Here, we demonstrate that novel thiazolide derivatives with variation in their substituents of the benzene ring do not significantly affect apoptosis induction in Caco-2 cells, whereas removal of the bromide atom on the thiazole ring leads to a strong reduction of cell death induction in colon cancer cells. We further show that active thiazolides require caspase activation and GSTP1 expression in order to induce apoptosis. We demonstrate that increased glutathione (GSH) levels sensitize colon cancer cells to thiazolides, indicating that both GSTP1 enzymatic activity as well as GSH levels are critical factors in thiazolide-induced cell death.

Glucose flux through glucokinase (GK) controls insulin release from the pancreas in response to high levels of glucose. Flux through GK is also responsible for reducing hepatic glucose output. Since many individuals with type 2 diabetes appear to have an inadequacy or defect in one or both of these processes, identifying compounds that can activate GK could provide a therapeutic benefit. Herein we report the further structure activity studies of a novel series of glucokinase activators (GKA). These studies led to the identification of pyridine 72 as a potent GKA that lowered post-prandial glucose in normal C57BL/6J mice, and after 14d dosing in ob/ob mice.

Transition metal-catalysed C-H bond functionalisation is an attractive approach for assembling valuable complex intermediates for the synthesis of pharmaceuticals, natural products, agrochemicals and fine chemicals. Selective functionalisation of one specific C-H site within a complex molecule without the assistance of a directing group is one of the major challenges in organic synthesis. The non-directed functionalisation of C-H bonds is more attractive and straightforward than the directed approach. While several reviews have covered (hetero)aryl (pseudo)halides as coupling partners in non-directed C-H bond functionalisation, this review will complement these existing contributions by focusing on the recent developments involving the employment of organometallic reagents for palladium-catalysed non-directed C-H bond functionalisation of (hetero)arene C-H bonds. Additionally, C-H/C-H bond coupling and other coupling partners will also be fully described.

This review includes the non-patent literature up to October 2004 that deals with selective neuronal nitric oxide synthase inhibitors (highest potency is for the neuronal isozyme). Some non-selective inhibitors or selective inducible nitric oxide synthase inhibitors are mentioned if they are related to compounds that are discussed; structures of these compounds generally are not given. In vitro inhibition constants are given either as IC50 values or as Ki values. An IC50 value, the inhibitor concentration that produces 50% inhibition in the presence of a constant concentration of substrate, is obtained by extrapolation of several rate data points to 50% inhibition. Ki values are derived from several types of plots that relate the concentration of inhibitor with enzyme velocity in the presence of a variety of substrate concentrations [1]. The Ki value can be estimated from the IC50 value [2]. Although the two inhibition constants are related, they are not the same; generally, the reported Ki values tend to be lower than the IC50 values. If specifics are desired about how the data were collected, then the reader will have to look in the literature cited. No attempt was made to be exhaustive in citing all references related to specific inhibitors; rather, examples of literature references are given for each inhibitor described.
