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.

Pittsburgh Compound-B (PIB) is currently being evaluated clinically for in vivo visualization of amyloid plaques in patients with Alzheimer’s disease (AD). We have synthesized three structural isomers of 6-hydroxy-2-(4?-aminophenyl)-1,3-benzothiazole, performed radiolabelling with carbon-11 and investigated their in vivo and in vitro properties. Specific binding to amyloid plaques was demonstrated in vitro using post-mortem brain homogenates of AD patients, transgenic AD mice brain sections and post-mortem human AD brain sections. In normal mice, initial brain uptake (at 2 min p.i.) was high and was followed by a fast wash-out. The three structural analogues have a high potential as tracer agents for in vivo visualization of amyloid plaques in AD patients.

Synthetic Route of 2516-40-7, Chemistry can be defined as the study of matter and the changes it undergoes. You¡¯ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.2516-40-7, Name is 2-Bromobenzothiazole, molecular formula is C7H4BrNS. In a patent, introducing its new discovery.

N?C?N cyclometalated iridium(III) acetylide complexes in the 3 + 2+1 ligand mode were obtained and characterized. Cyclometalating ligands were bis(pyridyl)phenyl, bis(benzothiazolyl)phenyl and 2-phenylpyridine derivatives, while acetylene ligands represented 2-ethynylfluorene and 3-ethynylcarbazole derivatives. The HOMOs of the ethynyl iridium complexes are located on the ethynyl ligand and the iridium atom, whereas the LUMO is located exclusively on the N?C?N-cyclometalating ligand. All compounds showed phosphorescent properties, where the change of ligands significantly affects the wavelength of emission. Acetylide complexes emit light from the blue (? 400 nm) to orange (? 560 nm) range. Emission occurs from the mixed state 3MLCT/3LC, with a predominance of junction depending on the structure of the ligands.
