β¦ Synopsis
The sulfonamide substituted pyranones (1) have recently been shown to be potent HIV protease inhibitors. We prepared a series of sulfone substituted analogs and compared their biological activities to those of the corresponding sulfonamide analogs. It was determined that although these compounds maintained activity as enzyme inhibitors, they showed somewhat diminished antiviral activity even though they may possess increased membrane permeability.

The cyclizatlon of the linear hydroxyethylene isostere based HIV-PR inhibitors gave the delta lactam XQ921, which was found to have a K i = 9.4 uM. It is proposed that a major reason for the weaker potency of the lactam XQ921 compared to cycliv urea based inhibitors is the lack of a PI' substituent
