and CYP26B1 is unknown, and no selective CYP26A1 or CYP26B1 inhibitors have been developed. Here the synthesis and potent inhibitory activity of the first CYP26A1 selective inhibitors is reported. A series of nonazole CYP26A1 selective inhibitors was identified with low nM potency. The lead compound 3-4-[2-(5,5,8,8-tetramethyl-5,6,7,8-tetrahydronaphthalen-2-yl)-1,3-dioxolan-2-yl] phenyl}4-propanoic
细胞色素P450 CYP26酶负责全反式维甲酸(t RA)的清除。抑制CYP26酶会增加内源性t RA浓度,并且是有吸引力的治疗靶标。但是,尚不存在现有的t RA代谢抑制剂对CYP26A1和CYP26B1的选择性和效力,因此尚未开发出选择性的CYP26A1或CYP26B1抑制剂。此处报道了首批CYP26A1选择性抑制剂的合成和强抑制活性。鉴定出一系列的nazole CYP26A1选择性抑制剂具有低nM效能。铅化合物3- 4- [2-(5,5,8,8-四甲基-5,6,7,8-四氢萘-2-基)-1,3-二氧戊环-2-基]苯基} 4 -丙酸(24)对CYP26A1有43倍的选择性,IC 50为340 nM。化合物24及其两个结构类似物也抑制了HepG2细胞中的t RA代谢,导致t RA增强RAR激活的能力。所鉴定的化合物具有成为旨在提高内源性t RA浓度的新型治疗方法的潜力,并且可用作与t RA共同治疗以抵抗治疗耐药性的方法。
