A series of triaryl pyrazoles were identified as potent pan antagonists for the retinoic acid receptors (RARs) α, β and γ. X-ray crystallography and structure-based drug design were used to improve selectivity for RARγ by targeting residue differences in the ligand binding pockets of these receptors. This resulted in the discovery of novel antagonists which maintained RARγ potency but were greater than
一系列三芳基吡唑被确定为视黄酸受体(RAR)α,β和γ的有效泛拮抗剂。X射线晶体学和基于结构的药物设计被用来通过针对这些受体的配体结合口袋中的残基差异来提高对RARγ的选择性。这导致发现了新的拮抗剂,它们与RARα和RARβ相比,具有维持RARγ效力但选择性大于500倍的特性。有效的选择性RARγ拮抗剂LY2955303具有良好的药代动力学特性,在骨关节炎样关节痛的MIA模型中有效。该化合物对RARα介导的不良反应显示出改善的余量。
