relationship studies concluded that the fragment N-benzoyl-Trp-Phe-OMe (3) was most suitable as a core structure for interaction with FPR1, and may be approved as a lead for the development of new drugs in the treatment of neutrophilic inflammatory diseases. As some of the synthesized compounds exhibited separable conformational isomers, and showed diverse bioactivities, the conformation analysis of these
我们以前的研究确定了Fmoc-(S,R)-色氨酸的二肽衍生物1,该衍生物选择性地抑制由N诱导的嗜中性白细胞弹性蛋白酶的释放。甲酰基大号-methionyl-大号-leucyl-大号苯基丙氨酸(FMLP)在人类嗜中性粒细胞中。为了提高药理活性,合成了一系列含色氨酸的二肽,并研究了它们在人嗜中性粒细胞中的药理活性。在这些中,五种化合物3,6,图19A,24A,和24B显示出有效的和双重抑制上fMLP诱导超氧阴离子(O效果2 ˙ - )的产生和嗜中性弹性蛋白酶的释放在嗜中性粒细胞与IC 50分别为0.23 / 0.60、1.88 / 2.47、1.87 / 3.60、0.12 / 0.37和1.32 / 1.03μM。进一步的研究表明,这些二肽抑制人中性粒细胞超氧化物的产生与甲酰肽受体1(FPR1)的选择性抑制有关。此外,结构-活性关系研究的结果表明,片段N-苯甲酰-Trp-Phe-OMe(3)
