Synthesis and biological evaluation of a new series of phenothiazine-containing protein farnesyltransferase inhibitors
摘要:
Two new families of human farnesyltransferase inhibitors 13a-m and 14a-d, based on a phenothiazine scaffold, were synthesized. Compounds 14a and 14b were the most promising inhibitors of human farnesyltransferase with IC50 values of 0.7 and 0.6 mu M, respectively. (C) 2012 Elsevier Masson SAS. All rights reserved.
A new family of 30 benzoylated N-ylides 4 and 5 was synthesized and evaluated for the inhibitory activity on human protein farnesyltransferase. Most of these novel compounds possessed in vitro inhibition potencies in the micromolar range. The nature of the substituents on the pyridine and phenyl units proved to be important in determining inhibitory activity and generally, the replacement of the cyanoacrylonitrile function by a cyanoethylacrylate group decreased the biological potential on farnesyltransferase. These results completed our SAR study on this original class of N-ylides. (C) 2013 Elsevier Ltd. All rights reserved.
