5‐substituted triazoles, identically 3,5‐disubstituted triazoles, 5‐substituted‐1H‐ and 5‐substituted‐2H‐tetrazoles proved to be detrimental to the inhibition of HO, with a few exceptions. The azole‐dioxolanes and the azole‐alcohols derived from the active azole‐ketones were synthesized also, but these inhibitors were less active than the corresponding imidazole‐based analogs. The first reported X‐ray crystal
为抑制血红素加氧酶(血红素加氧酶-1和血红素加氧酶-2),设计并合成了一系列的1-偶氮基-4-苯基-2-丁酮。用其他唑类取代咪唑导致发现了新型的1 H -1,2,4-三唑和1 H-四唑类抑制剂,与咪唑类铅抑制剂等效。具有2 H-四唑或1 H的抑制剂‐1,2,3-三唑作为药效基团的效力较低。通过各种吸电子或给电子的,小的或庞大的基团,在咪唑的2或4(5)位置被单取代,或在咪唑的4和5位置相同的解离,以及用阵列代替传统的咪唑药效基团3或5取代的三唑,3,5-二取代的三唑,5取代的1 H和5取代的2 H除少数例外,四唑类被证明对HO的抑制是有害的。还合成了由活性唑酮衍生的唑二氧杂戊环酮和唑醇,但这些抑制剂的活性低于相应的基于咪唑的类似物。首次报道了人类血红素加氧酶-1与1,2,4-三唑基抑制剂(即4-苯基-1-(1 H -1,2,4-三唑-1)的复合物的X射线晶体结构yl)-2-丁酮也已确定。该抑制剂通过三唑部分中的N
