The invention provides a series of thieno[2,3-b]pyridine derivatives wherein Y represents a linkage of formula C(O) or S(O)2; R1 represents hydrogen, halogen, cyano, nitro, C|-6 alkyl, trifluoromethyl, Ci.6 alkoxy, trifluoromethoxy, C1-6 alkylthio, C1-6 alkylsulphinyl or C1-6 alkylsulphonyl; R2 represents halogen, nitro, cyano, C1-6 alkyl, C2-6 alkynyl, hydroxy(C1-6)alkyl or formyl; and R3 represents a group of formula (a), (b), (c), (d) or (e): wherein the asterisk (*) represents the point of attachment to the remainder of the molecule. The compounds of formula (I) are selective inhibitors of human MEK (MAPICIC) enzymes and are accordingly of benefit in medicine, for example in the treatment of inflammatory, autoimmune, cardiovascular, proliferative (including oncological) and nociceptive conditions.
该发明提供了一系列噻吩[2,3-b]吡啶衍生物,其中Y代表公式C(O)或S(O)2的连接;R1代表氢、卤素、氰基、硝基、C1-6烷基、三氟甲基、C1-6烷氧基、三氟甲氧基、C1-6烷基硫基、C1-6烷基亚砜基或C1-6烷基砜基;R2代表卤素、硝基、氰基、C1-6烷基、C2-6炔基、羟基(C1-6)烷基或甲酰基;R3代表公式(a)、(b)、(c)、(d)或(e)的基团:其中星号(*)代表连接到分子其余部分的点。公式(I)的化合物是人类MEK(MAPICIC)酶的选择性抑制剂,因此在医学上具有益处,例如在治疗炎症、自身免疫、心血管、增殖(包括肿瘤学)和疼痛性疾病方面。
