substituted thiazole derivatives were designed, synthesized and characterized by FTIR, 1H, &13C NMR spectroscopy. The derivatives were then evaluated for their potential to inhibit 15-LOX and bovine carbonic anhydrase II (bCA II). Most of these compounds showed excellent inhibitory potential for 15-LOX with an IC50 of 0.12 ± 0.002 to 0.69 ± 0.5 μM and showed moderate inhibition potency for bCA II with compound
15-Lipoxygenase(15-LOX)在许多炎症性肺病(包括慢性阻塞性肺病(COPD),哮喘和慢性支气管炎)中起主要作用。15-LOX的过表达与某些特定的癌症有关,包括胰腺癌,胃癌和脑癌。类似地,在碳酸酐酶(CA)的不同同工酶之间,CA II在胰腺癌,胃癌以及脑肿瘤中表达。因此,需要新的有效的15-LOX和CA II抑制剂来进一步探索这些酶的作用并促进药物发现。为此,通过FTIR,1H和13C NMR光谱设计,合成和表征了一系列苄基二甲基-肼基取代的噻唑衍生物。然后评估衍生物抑制15-LOX和牛碳酸酐酶II(bCA II)的潜力。这些化合物大多数对15-LOX表现出极好的抑制潜能,IC50为0.12±0.002至0.69±0.5μM,对bCA II表现出中等抑制力,其中化合物5h最具活性(IC50 = 1.26±0.24μM)。最有效的化合物5a作为两种酶的双重抑制剂出现,对15-LOX的选择性是bCA
