Design, synthesis and biological evaluation of novel aliphatic amido/sulfonamido-quaternary ammonium salts as antitumor agents
摘要:
RhoB, one of the upstream signaling proteins of the phosphatidylinositol-3-kinase (PI3K)/Akt pathway, is frequently mutated in human cancer. Based on a piperazine alkyl derivative that induced apoptosis via up-regulation of RhoB, we synthesized novel aliphatic amido/sulfonamido-quaternary ammonium salts and evaluated their biological activities using an in vitro growth inhibition assay and RhoB promoter assay in human cancer cells. Compound 3a was the most promising anticancer agent in the series, based upon its potent growth inhibition via RhoB-mediated signaling. These novel aliphatic amido/sulfonamido- quaternary ammonium salts may be useful as a platform for development of anticancer chemotherapeutic agents. (C) 2012 Elsevier Ltd. All rights reserved.
Studies on Crude Drugs Effective on Visceral Larva Migrans. Part XVI. Nematocidal Activity of Long Alkyl Chain Amides, Amines, and Their Derivatives on Dog Roundworm Larvae.
activity of amides and amines having a long alkyl chain against the second-stage larva of dog roundworm, Toxocara canis, was examined. Long chain acyl amides with smaller substituents on the nitrogen showed stronger activity and the activity of cyclic amine amides was stronger than that of acyclic ones. In a series of homologous amides, the activity was dependent on the alkyl chain length: it reached
