derivatives was synthesized as dual inhibitors of thromboxane A(2) synthase (P450 TxA(2)) and aromatase (P450 arom). Dual inhibition of these enzymes could be a novel strategy for the treatment of mammary tumors and the prophylaxis of metastases. The most potent dual inhibitors, 5-(2-imidazol-1-ylethyl)-7,8-dihydroquinoline (31) (P450 TxA(2): IC(50) = 0.29 microM; P450 arom: IC(50) = 0.50 microM) and its
一系列的1-咪唑基(烷基)取代的喹啉,异喹啉,萘,苯并[b]呋喃和苯并[b]噻吩衍生物被合成为血栓烷A(2)合酶的双重抑制剂(P450 TxA(2))和芳香化酶(P450 arom)。对这些酶的双重抑制可能是治疗乳腺肿瘤和预防转移的新策略。最有效的双重抑制剂5-(2-咪唑-1-基乙基)-7,8-二氢喹啉(31)(P450 TxA(2):IC(50)= 0.29 microM; P450 arom:IC(50)= 0.50 microM)及其5、6饱和类似物30(P450 TxA(2):IC(50)= 0.68 microM; P450 arom:IC(50)= 0.38 microM)对两种目标酶的抑制作用均比参考化合物强(dazoxiben:IC(50)= 1.1 microM;氨基谷氨酰胺:IC(50)= 18.5 microM)。为了确定体内活性,在大鼠中检查了所选化合物对血清TxB(2)浓度的影响。化合物30(8
