A new series of 4-amino-6-methylthio-1H-pyrazolo[3,4-d]pyrimidines (2a-m) bearing the 2-chloro-2-phenylethyl chain at the N1 position, has been synthesized. The affinity of these compounds for A1 adenosine receptor (A1AR) was measured. The compounds showed poor affinity. A more interesting result was obtained by 2a, 2d, 2g, which demonstrated inhibitory activity on cell proliferation of the A-431 cell
合成了一系列新的4-氨基-6-甲硫基-1H-吡唑并[3,4-d]嘧啶(2a-m),在N1位带有2-氯-2-苯基乙基链。测量了这些化合物对A1腺苷受体(A1AR)的亲和力。化合物显示出较差的亲和力。通过2a,2d,2g获得了更有趣的结果,该结果显示了对上皮生长因子(EGF)刺激的A-431细胞系的细胞增殖和EGF受体酪氨酸激酶(EGFR-TK)磷酸化的抑制活性。
