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.

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.

In this paper, we present a novel concept for “smarter” photolabile organic compounds combining not one but two caged functions. As proof of principle, this diarylethene-based compound possesses two inhibited chemical groups (OMe and OAc) and its efficient release in different solvents is reported. In low- to medium-polarity media, both MeOH and AcOH are released, with a slight preferential uncaging of AcOH except in 1,4-dioxane, where MeOH is preferentially released. In contrast, DMSO or DMF render AcOH release strongly dominating. DFT calculations of the corresponding photoreactive conformations not only afford strong support to the observed release of MeOH and AcOH but also qualitatively explain the preferential release of acid in terms of dispersive noncovalent interactions. Finally, mechanistic aspects are discussed on the bases of the spectroscopic observations and of the TD-DFT calculations.

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.

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.

Cruzain is the major cysteine protease of T. cruzi, which is the causative agent of Chagas’ disease and is a promising target for the development of new chemotherapy. With the goal of developing potent nonpeptidic inhibitors of cruzain, the Substrate Activity Screening (SAS) method was used to screen a library of protease substrates initially designed to target the homologous human protease cathepsin S. Structure-based design was next used to further improve substrate cleavage efficiency by introducing additional binding interactions in the S3 pocket of cruzain. The optimized substrates were then converted to inhibitors by the introduction of cysteine protease mechanism-based pharmacophores. Inhibitor (38) was determined to be reversible even though it incorporated the vinyl sulfone pharmacophore that is well documented to give irreversible cruzain inhibition for peptidic inhibitors. The previously unexplored beta-chloro vinyl sulfone pharmacophore provided mechanistic insight that led to the development of potent irreversible acyl- and aryl- oxymethyl ketone cruzain inhibitors. For these inhibitors, potency did not solely depend on leaving group pTa, with 2,3,5,6-tetrafluorophenoxy methyl ketone (54) identified as one of the most potent inhibitors with a second order inactivation constant of 147,000 s-1M-1. This inhibitor completely eradicated the T. cruzi parasite from mammalian cell cultures and consequently has the potential to lead to new chemo therapeutics for Chagas’ disease.
