Compositions and methods for treating HIV/AIDS

Abstract

Compositions and methods for inhibiting HIV protease are disclosed. The compositions include an extract from Cassia acutifolia stems, or a fraction thereof, alone or in a pharmaceutically acceptable carrier. The extracts can be obtained by subjecting Cassia acutifolia pulverized stems to methanol/dichloromethane (1:1) extraction. In a first extraction stage, Cassia acutifolia pulverized stems are macerated in a mixture of methanol/dichloromethane. In a second stage methanol is added to the remaining marc vortex and extracted for a suitable time period at room temperature. The extract from the first and second stages are combined. The extracts can be further processed for formulation into a suitable pharmaceutical form.
