摘要:
Transposition of the pyridyl nitrogen from the P-3 substituent to the P-1' substituent in HIV-1 protease inhibitors (PI) affords compounds such as 3 with an improved inhibitory profile against multiple P450 isoforms. These compounds also displayed increased potency, with 3 inhibiting viral spread (CIC95) at <8 nM for every strain of PI-resistant HIV-1 tested. The poor to modest bioavailability of these compounds may correlate in part to their aqueous solubility. (C) 2003 Elsevier Ltd. All rights reserved.
