Several small molecule CD4mimics have been reported previously as HIV-1 entryinhibitors, which block the interaction between the Phe43 cavity of HIV-1 gp120 and the host CD4. Known CD4mimics such as NBD-556 possess significant anti-HIV activity but are less soluble in water, perhaps due to their hydrophobic aromatic ring-containing structures. Compounds with a pyridinyl group in place of the phenyl
Several small molecule CD4mimics, which inhibit the interaction of gp120 with CD4, have been developed. Original CD4mimics such as NBD-556, which has an aromatic ring, an oxalamide linker and a piperidine moiety, possess significant anti-HIV activity but with their hydrophobic aromatic ring-containing structures are poorly soluble in water. We have developed derivatives with a halopyridinyl group
