The potential for HIV fusion inhibition

In recent years, exciting developments in the understanding of the multi-step HIV-1 entry process have revealed potential approaches for therapeutic intervention that will compensate for the early disappointments of the soluble CD4 antigen approach. Although details of the HIV-1 fusion process are clearly complex, the proof-of-concept in the clinic provided by T-20 gives high hopes that new generation inhibitors of HIV fusion will be developed. This review highlights novel drug discovery technologies that are being employed in the search for such inhibitors. Curr Opin Infect Dis 14:13-16. (C) 2001 Lippincott Williams & Wilkins.
