(RXR) selective compound 4-[1-(3,5,5,8,8-pentamethyl-5,6,7,8-tetrahydro-2- naphthyl)ethenyl]benzoic acid (LGD1069), which is currently in phase I/IIA clinical trials for cancer and dermatological indications, have resulted in the identification of increasingly potent retinoids with > 1000-fold selectivity for the RXRs. This paper describes the design and preparation of a series of RXR selective retinoids
类维生素A X受体(RXR)选择性化合物4- [1-(3,5,5,8,8-五甲基-5,6,7,8-四氢-2-萘基)乙烯基]苯甲酸的结构修饰(LGD1069 )(目前正处于癌症和皮肤病适应症的I / IIA期临床试验中)已导致鉴定出越来越强的类维生素A,对RXR的选择性> 1000倍。本文介绍了一系列RXR选择性类维生素A的设计和制备,以及从共转染和竞争性结合试验中获得的生物学数据,这些数据用于评估其效力和选择性。最有效和最具选择性的类似物是6- [1-(3,5,5,8,8-五甲基-5,6,7,8-四氢萘-2-基)环丙基]烟酸(12d; LG100268) 。已证明该化合物可用于研究RXR依赖性生物途径,包括诱导程序性细胞死亡(PCD)和转谷氨酰胺酶(TGase)活性。我们的研究表明,人白血病髓样细胞中PCD和TGase的诱导依赖于RXR介导的途径的激活。
