biological evaluation of a number of differently substituted 3,6-diamino-1H-pyrazolo[3,4-b]pyridine derivatives are reported. From the inhibition results on a selection of disease-relevant protein kinases [IC50 (μM) DYRK1A = 11; CDK5 = 0.41; GSK-3 = 1.5] we have observed that 3,6-diamino-4-phenyl-1H-pyrazolo[3,4-b]pyridine-5-carbonitrile (4) constitutes a potential new and simple lead compound in the
报道了许多不同取代的3,6-二氨基-1 H-吡唑并[3,4- b ]吡啶衍生物的合成和生物学评价。从抑制结果中选择与疾病相关的蛋白激酶[IC 50(μM)DYRK1A = 11;CDK5 = 0.41;GSK-3 = 1.5]我们已经观察到3,6-二氨基-4-苯基-1 H-吡唑并[3,4- b ]吡啶-5-甲腈(4)构成了潜在的新颖且简单的先导化合物用于治疗阿尔茨海默氏病的药物。
