hopping followed by docking of a set of ∼200 compounds containing the acetyl indole scaffold. Chemical synthesis of nearly 30 derivatives has resulted in ligands of representatives of three subfamilies of human bromodomains with favorable ligand efficiency. The X-ray crystal structures of three different bromodomains (CREBBP, BAZ2B, and BRPF1b) in complex with acetyl indole derivatives reveal the influence
CREBBP和BAZ2B溴结构域的小分子命中已通过支架跳跃鉴定,然后对接约200种含乙酰基吲哚支架的化合物。近30种衍生物的化学合成产生了具有良好配体效率的人类溴结构域的三个亚家族的代表配体。三种不同的溴结构域(CREBBP,BAZ2B和BRPF1b)与乙酰基吲哚衍生物复合的X射线晶体结构揭示了关守残基对乙酰基赖氨酸结合位点中小分子配体取向的影响。
