结构:奥马维洛龙{N-[(4aS,6aR,6 bS,8aR,12 aS,14 aR,14 bS)-11-氰基-2,2,6a,6 b,9,9,12 a-七甲基-10,14-二氧代-1,2,3,4,4a,5,6,6a,6 b,7,8,8a,9,10,12 a,14,14 a,14 b-八-十氢吡喃-4a-基]-2,3,4,5,6,6,6 a,6 b,7,8,8 a,9,10,12 a,14,14 a,14 b-八-十氢吡喃-4a-基]-2,3,4,5,6,7,8,8 a,9,10,12 a,14,14 a,14 b-八-十氢吡喃-4a-基]-2,4,2-二氟丙酰胺}是基于天然产物油酸的半合成三萜类化合物。它含有高度反应性的氰基烯酮官能团,其通过迈克尔加成与蛋白质中的半胱氨酸共价可逆地结合,例如基于半胱氨酸的传感器蛋白Kelch样ECH相关蛋白1(KEAP 1)。奥玛洛酮的分子式为C33 H44 F2 N2 O3,分子量为554.7 g/mol。
STRUCTURE: Omaveloxolone {N-[(4aS, 6aR, 6bS, 8aR, 12aS, 14aR, 14bS)-11-cyano-2, 2, 6a, 6b, 9, 9, 12aheptamethyl-10, 14-dioxo-1, 2, 3, 4, 4a, 5, 6, 6a, 6b, 7, 8, 8a, 9, 10, 12a, 14, 14a, 14b-octa-decahydropicen-4a-yl]-2, 2-difluoropropanamide} is a semisynthetic triterpenoid based on the natural product oleanolic acid. It contains a highly reactive cyanoenone functionality, which binds covalently and reversibly by Michael addition to cysteines in proteins, such as the cysteine-based sensor protein Kelch-like ECH-associated protein 1 (KEAP1). The molecular formula of omaveloxolone is C33H44F2N2O3 and its molecular weight is 554.7 g/mol.
