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.

The invention provides methods, compositions, and kits for the inhibition of members of the Rho GTPase family. Specifically, the invention provides methods, compositions and kits for the inhibition of RhoA and/or RhoC transcriptional signalling. The invention finds use in treatment of Rho-mediated disease states (e.g., tumor metastasis, inflammation, inflammatory disease), Rho-mediated biological conditions, and in cell signaling research.

catalysis. Reaction kinetics of a key C−N coupling step with acyl azide and 1,4,2‐dioxazol‐5‐one led us to conclude that dioxazolones are much more efficient in mediating the formation of a carbon−nitrogen bond from an iridacyclic intermediate. Computational analysis revealed that the origin of higher reactivity is asynchronous decarboxylation motion, which may facilitate the formation of Ir‐imido species
