The synthesis of a new series of P450 17 inhibitors is described. The imidazol-1-yl compounds 5 showed strong inhibition of P450 17 rat and especially human enzyme, the most active compounds being 5ax, 5ay and 5bx with IC50 values of 0.17, 0.24 and 0.25 microM, respectively (ketoconazole: 0.74 microM). The 1,2,4-triazol-1-yl compounds 6 were less active, while the 1,2,4-triazol-4-yl compounds 7 were
描述了一系列新的P450 17抑制剂的合成。咪唑-1-基化合物5对P450 17大鼠尤其是人的酶显示出强烈的抑制作用,活性最高的化合物是5ax,5ay和5bx,IC50值分别为0.17、0.24和0.25 microM(酮康唑:0.74 microM)。1,2,4-三唑-1-基化合物6的活性较低,而1,2,4-三唑-4-基化合物7的活性较低。标题化合物显示对P450 arom几乎没有抑制作用。活性最强的P450 17抑制剂5ax和5ay在施用0.019 mmol / kg后2 h显着降低SD大鼠睾丸激素的血浆浓度。6小时后,5ay仍然表现出很强的作用。
