Design, synthesis and prostate cancer cell-based studies of analogs of the Rho/MKL1 transcriptional pathway inhibitor, CCG-1423
摘要:
We recently identified bis(amide) CCG-1423 (1) as a novel inhibitor of RhoA/C-mediated gene transcription that is capable of inhibiting invasion of PC-3 prostate cancer cells in a Matrigel model of metastasis. An initial structure-activity relationship study focusing on bioisosteric replacement of the amides and conformational restriction identified two compounds, 4g and 8, with improved selectivity for inhibition of RhoA/C-mediated gene transcription and attenuated cytotoxicity relative to 1. Both compounds were also capable of inhibiting cell invasion with equal efficacy to 1 but with less attendant cytotoxicity. (C) 2009 Elsevier Ltd. All rights reserved.
A series of caspase inhibitorscontaining γ-amino acid moiety have been synthesized. A systemic study on their structure-activityrelationship of anti-apoptotic cellular activity is presented. These efforts led to the discovery of compound 20o as a potent caspase inhibitor, which demonstrated preclinical ameliorating total bilirubin efficacy with a significantly improved pharmacokinetic profile.

The silver-catalyzed decarboxylativetrifluoromethylation of aliphatic carboxylicacids is described. With AgNO3 as the catalyst and K2S2O8 as the oxidant, the reactions of aliphatic carboxylicacids with (bpy)Cu(CF3)3 (bpy = 2,2'-bipyridine) and ZnMe2 in aqueous acetonitrile at 40 °C afford the corresponding decarboxylativetrifluoromethylation products in good yield. The protocol is applicable to
