The invention provides methods for decreasing or inhibiting human immunodeficiency virus (HIV) infection or pathogenesis (e.g., illness) of a cell in vitro, ex vivo or in vivo, a symptom or pathology associated with human immunodeficiency virus (HIV) infection or pathogenesis (e.g., illness) in vitro, ex vivo or in vivo, or an adverse side effect of human immunodeficiency virus (HIV) infection or pathogenesis (e.g., illness) in vitro, ex vivo or in vivo. In one embodiment, a method of the invention includes treating a subject with an invention compound (e.g., cationic steroid antimicrobial or CSA).
A series of novel steroid derivatives are described. The steroid derivatives are antibacterial agents. The steroid derivatives also act to sensitize bacteria to other antibiotics including erythromycin and novobiocin.

Cholic acid derivatives appended with amine groups have been prepared for use as permeabilizers of the outer membranes of Gram-negative bacteria. These compounds interact synergistically with antibiotics such as erythromycin and novobiocin to inhibit growth of Gram-negative bacteria. When a hydrophobic chain is included on the permeabilizers, they can be converted into potent antibiotics. The role of the hydrophobic chain is to facilitate self-promoted transport of the cholic acid derivatives across the outer membrane of Gramnegative bacteria. These compounds share activities found with polymyxin B and derivatives.
