MONOCYCLIC PYRIDINE DERIVATIVE
-
Paragraph 0498; 0499; 0500, (2014/09/03)
The present invention provides a novel compound having FGFR inhibitory activity or a pharmaceutically acceptable salt thereof, and a pharmaceutical composition containing the same. Specifically, the present invention provides a compound represented by the following formula (I) or a pharmaceutically acceptable salt thereof: wherein n represents 0 to 2; A represents an arylene group or a heteroarylene group; G represents a single bond, an oxygen atom or —CH2—; E represents a nitrogen-containing non-aromatic heterocycle; R1 represents an alkoxy group or the like; R2 represents a hydrogen atom or the like; and R3 represents a hydrogen atom, an alkyl group, an alkoxy group or the like, with the proviso that when E represents an azetidine ring and R2 or R3 is present on a nitrogen atom on the azetidine ring, the R2 or R3 does not represent a hydrogen atom.

The series of 4-(benzylaminomethylene)isoquinoline-1,3-(2H,4H)-dione and 4-[(pyridylmethyl)aminometh-ylene]isoquinoline-1,3-(2H,4H)-dione derivatives reported here represents a novel class of potential antitumor agents, which potently and selectively inhibit CDK4 over CDK2 and CDK1. In the benzylamino headpiece, a 3-OH substituent is required on the phenyl ring for CDK4 inhibitory activity, which is further enhanced when an iodo, aryl, heteroaryl, t-butyl, or cyclopentyl substituent is introduced at the C-6 position of the isoquinoline-1,3-dione core. To circumvent the metabolic liability associated with the phenolic OH group on the 4-substituted 3-OH phenyl headpiece, we take two approaches: first, introduce a nitrogen o- or p- to the 3-OH group in the phenyl ring; second, replace the phenyl headpiece with N-substituted 2-pyridones. We present here the synthesis, SAR data, metabolic stability data, and a CDK4 mimic model that explains the binding, potency, and selectivity of our CDK4 selective inhibitors.
