synthesized and evaluated as inhibitors of guinea pig complement and in most cases its C1 component. The most active compounds were 3-(4-phenylphenylbutyl)-N-(6-choro-2-fluorosulfonylbenzyl) pyridinium bromide (43) and 3-(4-phenylphenylbutyl)-N-(2-fluorosulfonylbenzyl) pyridinium bromide (44), each showing 50% inhibition at 7.8 muM. The most effective irreversible inhibitor of the C1 component was N-
合成了一系列83种化合物,这些化合物通过通常用2-SO2F或6-Cl-2-SO2F基团与PhCH2Br季铵化而衍生自烃基取代的吡啶,并被用作豚鼠补体的抑制剂,在大多数情况下还用作其C1成分的抑制剂。活性最高的化合物是3-(4-苯基苯基丁基)-N-(6-氯-2-氟磺酰基苄基)吡啶鎓溴化物(43)和3-(4-苯基苯基丁基)-N-(2-氟磺酰基苄基)吡啶鎓溴化物(44) ,每一个在7.8μM时显示50%抑制。C1组分最有效的不可逆抑制剂是N-(6-氯-2-氟磺酰基苄基)-5,6-苯并喹啉溴化物(87),在4μM浓度下抑制50%。
