The 2-cyano-6-chloropyrazine's chlorine atom reactivity was substituted with amines 1,4-dioxo-8-azaspiro-[4, 5]-decane and 1-ethoxycarbonylpiperazine. The substrates thus obtained were used in the syntheses of the new derivatives, which were tested for their tuberculostatic activity. Minimum inhibitory concentration (MIC) value of the most active ones ( 5b , 12a , 14b , 16b , 21b ) was 25 μ g/mL.
2-cyano-6-chloropyrazine 的氯原子反应性被胺 1,4-dioxo-8-azaspiro-[4, 5]-decane 和 1-ethoxycarbonylpiperazine 取代。如此获得的底物用于合成新衍生物,并测试它们的抗结核活性。最活跃的那些(5b、12a、14b、16b、21b)的最小抑菌浓度(MIC)值为25μg/mL。
