anti-HIV fusion inhibitory peptides are stabilized by the amino acid sequence and by intrachain hydrogen bonds. The study of peptide analogues using (E)-alkene and (Z)-fluoroalkene dipeptide isosteres demonstrated the substantial, yet position-dependent, contribution of hydrogen bonds to the α-helix stability and anti-HIV bioactivity.
抗HIV融合抑制肽的α-螺旋结构通过氨基酸序列和链内氢键稳定。使用(E)-烯烃和(Z)-氟烯烃二肽等排体的肽类似物的研究表明,氢键对α-螺旋稳定性和抗HIV生物活性的贡献很大,但与位置有关。
