of vitamin D receptor (VDR)-mediated transcription is expected to be of therapeutic value in Paget’s disease of bone. It is known that interaction between VDR and coactivators is necessary for VDR transactivation, and the interaction occurs when VDR recognizes an LXXLL peptide motif of coactivators. We previously reported that benzodiazepine derivatives designed as LXXLL peptide mimetics inhibited the
预期维生素D受体(VDR)介导的转录的抑制在佩吉特氏骨病中具有治疗价值。众所周知,VDR和共激活因子之间的相互作用是VDR反激活所必需的,并且当VDR识别共激活因子的LXXLL肽基序时,就会发生相互作用。我们以前曾报道过,设计为LXXLL肽模拟物的苯二氮卓衍生物可抑制VDR和共激活剂的相互作用,并减少VDR转录。在这里,我们研究了7位和8位取代的苯二氮卓衍生物的构效关系,并确定8位的氨基对于抑制活性至关重要。
