(ara-A), 7-deaza-EHNA being the most active of all. The results obtained showed that there is no correlation between adenosine deaminase inhibition and antiviral or antitumor activity in this series of compounds. 3-Deaza-EHNA, the most active inhibitor of ADA among the EHNA deaza analogues, greatly potentiates the antitumor activity of ara-A in vitro. In vivo activity was observed only when the two compounds
合成了两个新的赤型9-(2-羟基-3-壬基)腺嘌呤(EHNA,1)的deaza类似物,7-deaza-EHNA(6)和1,3-dideaza-EHNA(11)。腺苷脱氨酶(ADA)抑制活性,并与EHNA,1-deaza-EHNA(2)和3-deaza-EHNA(3)比较。用次甲基取代EHNA嘌呤部分7位上的氮原子会导致抑制活性急剧下降(Ki = 4 X 10(-4)M),而化合物2和3仍然是好的抑制剂( Ki = 1.2 X 10(-7)M和6.3 X 10(-9)M)。到目前为止,还对体外合成的EHNA及其deaza类似物在一系列细胞系统中的抗病毒和抗肿瘤活性进行了测试。EHNA和1-deaza-EHNA具有抑制人类呼吸道合胞病毒(HRSV)复制的作用(MIC = 6)。25微克/毫升),而其他化合物则没有活性。另一方面,所有检查的化合物显示出与参考化合物1-β-D-呋喃糖基丝氨酸腺嘌呤
