  Discovery of an androgen receptor modulator pharmacophore based on 2-quinolinones

  摘要：

  A series of alkylamino-2-quinolin one compounds (3) was discovered as androgen receptor modulators based on an early linear tricyclic quinoline pharmacophore (1). The series demonstrated selective high binding affinity to androgen receptor and potent receptor modulating activities in the cotransfection assays. (c) 2007 Elsevier Ltd. All rights reserved.
