摘要:
Indole-3-amides and dipeptides were produced from 2-aminobenzothiazoles using the PyBop peptide coupling reagent. These analogues were tested in anti-cancer cell viability assays against SH-SY5Y neuroblastoma and MDA-MB-231 breast adenocarcinoma cell lines, and were found to exhibit cytotoxic activities at concentrations ranging from 0.1 to 20 mu M. These compounds were also found to act additively with a low dosage of 13-cis-retinoic acid in neuroblastoma cells. Then, using neuroblastoma cells transfected to stably overexpress the RAR beta(2) gene, a SAR was developed for the indole-3-amides. Real-time PCR was also used to demonstrate their RAR beta(2) agonistic activity. (C) 2012 Elsevier Ltd. All rights reserved.
