Based on the structural analysis of FIV protease and drug-resistant HIV proteases and molecular modeling, a new type of inhibitors with a small P3 residue has been developed. These inhibitors are effective against HIV and its drug-resistant mutants, as well as SIV and FIV. Modification of existing HIV protease inhibitors by reducing the size of the P3 residue has the same effect. This finding provides a new strategy for the development of HIV protease inhibitors effective against the wild-type and drug-resistant mutants. It further supports the use of FIV protease as a useful model for drug-resistant HIV proteases, which often have a more constricted binding region for the P3 group or the combined P3 and P1 groups.

Chemistry is the experimental science by definition. We want to make observations to prove hypothesis. For this purpose, we perform experiments in the lab. 348-40-3, Name is 6-Fluorobenzo[d]thiazol-2-amine348-40-3, introducing its new discovery.

Benzothiazole and imidazole compounds are extensively studied heterocyclics due to their wide spectrum of bioactivities. Among them, the imidazo(2,1-b)-benzothiazole derivatives are pharmacologically important because of their immunostimulant, anti-inflammatory, antifungal, antimicrobial, antitumor, and other activities. In the present research work, a novel series of 2,3-diaryl-substituted imidazo(2,1-b)-benzothiazoles 13a-o have been synthesized by reaction of substituted 2-aminobenzothiazoles 1-8 and an appropriately substituted a-bromo-1-(4?-substituted)-phenyl-2-(4?- substituted)-phenyl-1-ethanones 9-12 in the presence of anhydrous acetonitrile. They were characterized by physicochemical, elemental, and spectral (IR, 1H-NMR, and Mass) data. All the synthesized compounds were screened for their in-vitro antibacterial activity against Gram-positive, Gram-negative bacteria. The investigation of antibacterial screening data revealed that most of the compounds tested have demonstrated congruent activity against Staphylococcus aureus, Bacillus subtilis, Escherichia coli, and Pseudomonas aeruginosa as compared with the standard ampicillin. Among the series, compounds 13d, 13h, and 13m exhibited excellent an antibacterial activity profile as compared with the standard. In summary, preliminary results indicate that some of the newly synthesized title compounds exhibited promising antibacterial activities and they warrant more consideration as prospective antimicrobials.

The synthesis of 19 compounds associating a thiol function and a basic heterocycle (i.e. benzimidazole, pyridine, thiazole) is described.Their esterolytic activity towards para nitrophenyl acetate (PNPA) is compared with that of simple monofunctional thiols.The influence of the substituents and of the nature of the basic heterocycle shows that the apparition of a cooperative effect depends both on the relative pKa values (thiol and heterocyclic) and on the possibility of proton exchange via the heterocyclic moiety.Examples of bifonctional process are reported in the case of benzimidazolylmethanethiol compounds, due to a basic assistancce on the neutral form of the thiol function.

The reactivity of heteroarylic ketones toward vinylmagnesium bromide (2) and the regiochemistry of the addition were investigated. The reactivity drastically increases when the carbonyl is conjugated with at least one aza group and the regiochemistry of the addition of the vinyl Grignard reagent depends on the carbonyl compound: in the series of di(heteroazolyl) ketones the O-alkylation product was observed as unique with di(1,3-benzothiazol-2-yl) ketone, and in different relative ratios with respect to the classic C-alkylation product with di(1,3-thiazol-2-yl) ketone, (1,3-benzothiazol-2-yl) (1,3-thiazol-2-yl) ketone, and di(1,3-benzoxazol-2-yl) ketone, whereas di(N-methylbenzimidazol-2-yl) ketone gave the exclusive formation of the carbinol. This behavior can be explained by the intervention of the delocalization power of the heterocyclic ring and this was confirmed by the results obtained from the reaction between vinylmagnesium bromide and a series of mixed (1,3-benzothiazol-2-yl) (para-substituted phenyl) ketones, that showed a relative O-/C-alkylation ratio dependent on the nature and on the electronic effect of the substituent on the phenyl ring. The results are in agreement with the existence of intermediate species bearing a negative charge on the benzylic carbonyl carbon atom, and make the O-alkylation reaction between vinyl Grignard reagents and carbonyl compounds no longer a rare case, since it was observed with a number of heterocyclic carbonyl compounds, such as (1,3-benzothiazol-2- yl) aryl ketones and di(heteroaryl) ketones of the pentatomic 1,3-heteroazolic series.
