Fifteen acetyl-peptide-amides with partial amino acid sequences of RANTES (regulated upon activation, normal T-cell expressed and secreted), all Cys residues of which were substituted by Ala, were synthesized, and screened for anti-HIV-1 activity. Peptides corresponding to 1-10, 37-46, and 57-68 showed marked activity against CC-chemokine receptor 5-using HIV-1(JR-CSF) (% inhibition at 100 nM 69, 82, 76%, respectively). The results indicate that multiple regions, including the N-terminal part responsible for chemotactic activity, are involved in anti-HIV-1 activity of RANTES, yielding possible lead compounds for anti-HIV-1 agents.
合成了15种具有RANTES(活化时调节、正常T细胞表达和分泌)部分氨基酸序列的乙酰化肽酰胺,其中所有半胱氨酸残基均被丙氨酸取代,并筛选了其抗HIV-1活性。对应于1-10、37-46和57-68的肽对使用CC趋化因子受体5的HIV-1(JR-CSF)显示出显著活性(在100 nM时的抑制率分别为69%、82%、76%)。结果表明,包括负责趋化活性的N端部分在内的多个区域参与了RANTES的抗HIV-1活性,从而产生了可能的抗HIV-1药物先导化合物。
