We report here the synthesis and activity of new analogs of the N-formyl and N-tert-butyloxycarbonyl (Boc) derivatives of the tripeptide Met-Leu-Phe-OMe containing an achiral omega-amino acid residue replacing the hydrophobic central leucine. The tripeptides HCO-Met-NH-(CH2)n-CO-Phe-OMe and Boc-Met-NH-(CH2)n-CO-Phe-OMe (n = 3-5) containing the central homomorphic residue of 5-aminopentanoic acid (delta-aminovaleric
我们在这里报告的三肽Met-Leu-Phe-OMe的N-甲酰基和N-叔丁氧羰基(Boc)衍生物的新类似物的合成和活性,其包含非手性ω-氨基酸残基代替疏水中央亮氨酸。三肽HCO-Met-NH-(CH2)n-CO-Phe-OMe和Boc-Met-NH-(CH2)n-CO-Phe-OMe(n = 3-5)包含中心同态残基5-氨基戊酸(δ-氨基戊酸; delta-Ava; n = 4)以及4-氨基丁酸(γ-氨基丁酸;γ-Abu; n = 3)和6-氨基己酸(ε-氨基己酸;ε-Aca; n = 5)已被检查。已经确定了新类似物在趋化性,溶菌酶释放和超氧阴离子产生中作为激动剂和拮抗剂的活性。N-Boc衍生物2a和2b,
