The synthesis and structure-activity profile of a new class of potent and specific LTA4 hydrolase inhibitors are described. Many compounds of this series of omega-[5-(omega-arylalkyl)-2-thienyl]- and omega-[4-(omega-arylalkyl)phenyl]alkanoic acids were found to be potent in vitro inhibitors of the LTB4 production by porcine leukocytes with IC50 ranging from 1 to 10 microM. The side-chain lengths were
描述了新型有效和特异性LTA4水解酶抑制剂的合成和结构活性图。发现该系列的ω-[5-(ω-芳基烷基)-2-噻吩基]-和ω-[4-(ω-芳基烷基)苯基]链烷酸的许多化合物是有效的体外抑制LTB4产生的抑制剂猪白细胞,IC50为1至10 microM。侧链的长度对于最佳活性至关重要。亲脂性和供电子性取代基在苯系列末端芳香环上的取代作用大大增强了LTA4水解酶的抑制能力。另一方面,在噻吩系列中,这种取代对LTA4水解酶抑制的影响很小。在羧酸侧链中通过羰基或羟基的官能化导致效力较低的化合物。通过在羧酸侧链的β位插入一个氧原子,可获得代谢稳定的LTA4水解酶抑制剂RP64966。向大鼠口服施用RP64966后,发现血浆提取物显示出对LTB4生物合成的有效抑制作用(在5 mg / kg,口服时抑制40%)。
