Shiga-like toxins and ricin are ribosome-inactivating proteins (RIPs) that are lethal to mammals and pose a global health threat. No clinical vaccines or therapeutics currently exist to protect against these RIPs. Two small molecules (Retro-1 and Retro-2) were discovered with high-throughput screening and reported for their protection of cells against RIPs. Of great significance, Retro-2, repor...

pathogenic infections and inflammation are very common ailments humans suffer. upsurge of resistant pathogens has impeded the antimicrobial drug development process in recent years and the search of new antimicrobial agents is clearly evident from the literature. in line with these developments the synthesis of n-substituted aryl-2-({4-[(substituted aryl carbamoyl) methyl]-5-(pyridin-4-yl)-4h-1...

In the present study, the oxidation of 3-(4-chloro-1H-imidazol-5-yl)-1-(2-hydroxyphenyl)prop-2-en-1ones with mercuric(II) acetate in in polyethylene glycol (PEG-400) gave the corresponding 2-((4-chloro-1Himidazol-5-yl)methylene)benzofuran-3(2H)-ones. Newly synthesized compounds were tested for their in vitro antimicrobial activity.

A series of 14 (E)-cinnamic N-acylhydrazone derivatives, designed through molecular hybridization between the (E)-1-(benzo[d][1,3]dioxol-5-yl)-3-(4-bromophenyl)prop-2-en-1-one and (E)-3-hydroxy-N'-((2-hydroxynaphthalen-1-yl)methylene)-7-methoxy-2-naphthohydrazide, were tested for in vitro antiparasitic activity upon axenic amastigote forms of Leishmania donovani and bloodstream forms of Trypamo...

Newly synthesized 2-(2-((1H-indol-5yl)methylene)-hydrazinyl)-thiazole derivatives were evaluated for their in vitro cytotoxicity on two carcinoma cell lines A2780 and HeLa. Significant cytotoxic activity for 2-(2-((1H-indol-5-yl)methylene)hydrazinyl)-4-methylthiazole (1) and 2-(2-((1H-indol-5-yl)methylene)hydrazinyl)-4-phenylthiazole (3), on both A2780 [IC50: 11.6 μM (1), and 12.4 μM (3)] and H...
