atherosclerosis. Here we describe the synthesis of a series of C(5)-substituted analogues of the previously described 5-LO-activating protein (FLAP) inhibitor BRP-7 (IC50 = 0.31 muM) to explore the effects of substitution at the C(5)-benzimidazole (BI) ring as a strategy to increase the potency against FLAP-mediated 5-LO product formation. Incorporation of polar substituents on the C(5) position of the BI core
用5-脂氧合酶(5-LO)途径进行药理干预可抑制白三烯(LT)生物合成,这是经临床验证的策略,可用于治疗呼吸道和心血管疾病,例如哮喘和动脉粥样硬化。在这里我们描述了先前描述的5-LO激活蛋白(FLAP)抑制剂BRP-7(IC50 = 0.31μM)的一系列C(5)取代类似物的合成,以探讨在C(5 )-苯并咪唑(BI)环作为增加针对FLAP介导的5-LO产物形成的效力的策略。在BI核的C(5)位置上掺入极性取代基,例如具有C(5)-腈取代基的化合物11,可显着增强抑制人类嗜中性粒细胞中5-LO产物合成的能力(IC50 = 0.07μM )和单核细胞(IC50 = 0.026μM)。
