Diarylheterocycle Core Ring Features Effect in Selective COX-1 Inhibition

The COX-1 isoenzyme plays a significant role in a variety of diseases, as it catalyzes the bioprocesses behind many health problems. Among the diarylheterocycle class of COX inhibitors, the isoxazole ring has been widely used as a central heterocycle for the preparation of potent and selective COX-1 inhibitors such as P6 [3-(5-chlorofuran-2-yl)-5-methyl-4-phenylisoxazole]. The role of the isoxazole nucleus in COX-1 inhibitor selectivity has been clarified by preparing a set of new diarylheterocycles with various heterocycle cores. Replacement of isoxazole with isothiazole or pyrazole gave a drastic decrease in COX-1 inhibitory activity, whereas the introduction of an electron-donating group (EDG) on the N-aryl pyrazole allowed recovery of COX-1 inhibitory activity and selectivity. The EDG-equipped 5-(furan-2-yl)-1-(4-methoxyphenyl)-3-(trifluoromethyl)-1H-pyrazole (17) selectively inhibits COX-1 activity (IC50=3.4 mu M; 28?% COX-2 inhibition at 50 mu M), in contrast to its inactive analogue, 3-(furan-2-yl)-1-phenyl-5-(trifluoromethyl)-1H-pyrazole, which does not bear the methoxy EDG. Molecular docking studies of compound 17 into the binding site of COX-1 shed light on its binding mode.

Antidermatophytic activity of pyrazolo[3,4-c]isothiazoles: a preliminary approach on 4-chlorophenyl derivative for evaluation of mutagenic and clastogenic effects on bacteria and human chromosomes in vitro

The antifungal activity of eight pyrazolo[3,4-c]isothiazole derivatives was evaluated on five dermatophytes: three were of an anthropophilic species (i.e., Epidermophyton floccosum, Trichophyton rubrum, and Trichophyton tonsurans) and two were of a geophilic species (i.e., Microsporum gypseum and Nannizzia cajetani). The new compounds proved to be unlikely effective in inhibiting the growth of the different strains. In general, the fungi parasitic on man were more sensitive than the geophilic species. This fact can be positive for a possible practical-therapeutic utilization of this class of compounds. To verify their possible use against fungi of medical interest, the most interesting substance at low doses, 6-(4-chlorophenyl)-4-methyl-6H-pyrazolo[3,4-c]isothiazol-3-amine, was chosen to perform in vitro genotoxicity tests using the following: Salmonella/microsome test (SAL), sister chromatid excange test (SCE), cytokinesis-blocked micronucleus test (CBMN), and its improvement (Ara-C/CBMN). The compound showed no mutagenic activity at low doses, whereas at the highest dose (100 mu g/mL), it caused a generalized cytotoxic effect. The high growth inhibition exerted on fungi at the lowest dose and the concomitant lack of genotoxicity, at least until the dose of 50 mu g/mL, might suggest the compound as a safe candidate as an antidermatophytic substance.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 824-79-3, in my other articles.

A new monoclinic polymorph of 3-diethylamino-4-(4-methoxyphenyl)-1,1-dioxo-4H-1 lambda 6,2-thiazete-4-carbonitrile

A new monoclinic form of the title compound, C14H17N3O3S, has been found upon slow crystallization from water. Another monoclinic form of the compound was obtained previously from a mixture of dichloromethane and diethyl ether [Clerici et al. (2002). Tetrahedron, 58, 5173-5178]. Both phases crystallize in space group P2(1)/n with one molecule in the asymmetric unit. The formally single exocyclic C-N bond that connects the -NEt2 unit with the thiazete ring is considerably shorter than the adjacent, formally double, endocyclic C=N bond. This is likely to be due to the extended conjugated system between the electron-donor diethylammine fragment and the electron-withdrawing sulfonyl group. In the newly discovered polymorph, the methoxy group is rotated by almost 180 degrees around the phenyl-OCH3 bond, resulting in a different molecular conformation.
