comparable to the known antibiotic Gentamicin. Compounds 26, 33, 39, 43, 44, 50, 55 and 63 showed broad spectrum antitumor activity with GI values range of 10.1–100%. Molecular modeling study concluded that recognition with key amino acid Glu30, Phe31 and Phe34 is essential for binding. ADMET properties prediction of the active compounds suggested that compounds 29 and 34 could be orally absorbed with
设计,合成并合成了一系列新的2-(1,3,4-噻二唑基或4-甲基噻唑基)硫代6-取代的喹唑啉-4-酮类似物,并对其体外DHFR抑制,抗菌,和抗肿瘤活性。化合物29,34,和39被证明是最活跃的DHFR抑制剂与IC 50值的范围为0.1〜0.6μm。化合物28,31和33表现出显着的广谱抗微生物活性相媲美的已知抗生素庆大霉素。化合物26,33,39,43,44,50,5563和63显示了广谱抗肿瘤活性,GI值范围为10.1–100%。分子模型研究得出结论,关键氨基酸Glu30,Phe31和Phe34的识别对于结合至关重要。活性化合物的ADMET性质预测表明,化合物29和34可以口服吸收,且毒性降低。
