with a furan substituent at C-5 and a 4-methylindol-5-ylamino substituent at C-4, 1, was a potent inhibitor of PKCθ (IC50 = 4.5 nM). Replacement of the C-5 furan ring of 1 with bicyclic heteroaryl rings, led to compounds with significantly improved potency against PKCθ. Analog 6b with a 4-methylindol-5-ylamino group at C-4 and a 5-[(4-methylpiperazin-1-yl)methyl]-1-benzofuran-2-yl group at C-5 had an
我们以前报道,与C-5呋喃取代基和4-甲基吲哚-5-基氨基取代基的C-4,3-吡啶腈类似物1,是PKCθ(IC的有效抑制剂50 = 4.5纳米)。的C-5呋喃环替换1与双环杂芳基环,导致了与显著提高的抗PKCθ效力的化合物。具有在C-4处的4-甲基吲哚-5-基氨基和在C-5具有5-[(4-甲基哌嗪-1-基)甲基] -1-苯并呋喃-2-基的类似物6b具有IC 50值抑制PKCθ为0.28nM。
