  Use of a Pharmacophore Model for the Design of EGFR Tyrosine Kinase Inhibitors:  Isoflavones and 3-Phenyl-4(1H)-quinolones

  摘要：

  Using a pharmacophore model for ATP-competitive inhibitors interacting with the active site of the EGFR protein tyrosine kinase together with published X-ray crystal data of quercetin (2) in complex with the lick tyrosine kinase and of deschloroflavopiridol (3b) in complex with CDK2, a putative binding mode of the isoflavone genistein (1) was proposed. Then, based on literature data suggesting that a salicylic acid function, which is represented by the 5-hydroxy-4-keto motif in I, could serve as a pharmacophore replacement of a pyrimidine ring, superposition of 1 onto the potent EGFR tyrosine kinase inhibitor 4-(3'-chlorophenylamino)-6,7-dimethoxyquinazoline (4) led to 3'-chloro-5,7-clibydroxyisoflavone (fi) as a target structure which in fact was 10 times more potent than 1. The putative binding mode of 6 suggests a sulfur-aromatic interaction of the m-chlorophenyl moiety with Cys 773 in the "sugar pocket" of the EGFR kinase model. Replacement of the oxygen in the chromenone ring of 6 by a nitrogen atom further improved the inhibitory activity against the EGFR kinase. With IC50 values of 38 and 8 nM, respectively, the quinolones 11 and 12 were the most potent compounds of the series. N-Alkylation of II did not further improve enzyme inhibitory activity but; led to derivatives with cellular activity in the lower micromolar range.

  We have discovered that p63 inhibition results in increased cellular proliferation. We have also performed a screen for agents capable of increasing cellular proliferation, (e.g., of stem cells such as skin-derived precursors (SKPs)). The invention therefore invention provides compositions, methods, and kits for increasing proliferation of cells, using compounds that decrease p63 expression or activity or using the compounds described herein. The invention also features methods of using these compounds for increasing hair growth, improving skin health, or promoting skin repair in a subject.
