Anti-HIV activity of a series of cosalane amino acid conjugates
摘要:
The binding of the anti-HIV agent cosalane to CD4 is thought to involve ionic interactions of negatively charged carboxylates of the ligand with positively charged residues on the surface of the protein. The purpose of the present study was to examine the hypothesis that the two carboxyl groups of cosalane could be sacrificed through conjugation to amino acids, and the anti-HIV activity still be retained, provided that at least two new carboxyl groups are contributed by the amino acid residues.

The anti-HIV agent cosalane and several of its analogues inhibited RANTES-induced migration of human monocytes, but they did not inhibit migration induced by MIP1 alpha or MIP1 beta. RANTES-induced migration of single receptor CCR1-HEK transfectants was also inhibited by the cosalanes. Acetylation of the reactive amino groups of RANTES abrogated the inhibitory activity of cosalane. The data suggest that cosalane and its structural analogues may interfere with the RANTES/CCR1 interaction by binding to RANTES. (C) 2000 Elsevier Science Ltd. All rights reserved.
