Cosalane (NSC 658586) is a potent inhibitor of HIV replication. Cosalane has an intrinsic ability to block human and murine CCR7 function in vitro in response to both of its natural ligands, CCL19 and CCL21, with the IC50 of 0.207/2.66 μM in human for CCL19/CCL21 and 0.193/1.98 μM in murine, respectively[1][2].
