receptor tyrosine kinase or the PDGF receptor tyrosine kinase in a standard mitogenesis assay utilizing human fibroblasts, no discrimination was observed. In this assay, the compounds inhibited DNA synthesis when added to cells during S phase. This suggests that inhibition could not be interpreted in terms of tyrosine kinase inactivation but more likely as a relatively broad specificity for the ATP-binding

A binaphthyl‐supported Pd nanoparticles (Pd‐BNP)‐catalyzed aminocarbonylation of aryliodides in the presence of carbon monoxide and amines for the synthesis of amides has been developed. This methodology provides an efficient route for the synthesis of a COX‐2 enzyme inhibitor having anti‐inflammatory activity.

Two series of N,N′-diphenyl-benzamidines were synthesized as part of a study to search potential new drugs with antileishmanial activity. These compounds were obtained by anilides in PCl5 halogenation reaction with generation in situ of the corresponding benzimidoyl chlorides, and subsequently treatment with adequate anilines. The series I showed expressive results of antileishmanial activity, highlighted

decreased significantly if a chlorine or methoxy group replaced the fluorine atom. 3'-Fluoro-6-methoxy-2-phenyl-4-quinolone-3-carboxylic acid (68) had the highest in vitro cytotoxic activity among all tested carboxylic acid derivatives and their salts. The mechanism of action may be similar, but not identical, to that of tubulin binding drugs, such as navelbine and taxol. Compound 68 merits further investigation
