Abstract
The invention relates to a new class of compounds herein identified generally as “sultams”, which may be represented by the following formula V, in FIG. 1, in which numbering of the atoms is started with the sulfur atom of the isothiazole. Two of the rings (rings A and C) are aromatic, and the third is a heterocyclic ring (ring B), a cyclic sulfonamide. Of particular importance are the enantiomerically pure sultams since they are especially potent HIV-1 inhibitors.
