The key intermediate, 4-chloro-5-iodo-3-pyridinecarbonitrile, allowed for ready optimization of the PKCtheta inhibitory activity of a series of 3-pyridinecarbonitriles. Analog 13b with a 4-methylindol-5-ylamino group at C-4 and a 4-(2-(4-methylpiperazin-1-yl)ethoxy)phenyl group at C-5 had an IC(50) value of 7.4nM for the inhibition of PKCtheta.
关键中间体4-氯-5-碘-3-吡啶甲腈使得一系列3-吡啶甲腈的蛋白激酶Cθ（PKCθ）抑制活性能够轻易得到优化。在C-4位带有4-甲基吲哚-5-基氨基且在C-5位带有4-(2-(4-甲基哌嗪-1-基)乙氧基)苯基的类似物13b对PKCθ抑制的IC(50)值为7.4 nM。
