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).

The invention relates to methods for decreasing or inhibiting influenza virus infection or pathogenesis of a cell in vitro, ex vivo or in vivo, a symptom or pathology associated with influenza infection or pathogenesis in vitro, ex vivo or in vivo, or an adverse side effect of influenza infection or pathogenesis 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.

Attachment of amino acids to cholic acidderivatives yielded compounds that sensitize Gram-negative bacteria to hydrophobic antibiotics. Incorporation of three amino acid onto a cholic acidderivative via ester bonds was only achieved with non-α-branched amino acids. Three non-α-branched or three α-branched amino acids were coupled to the steroid backbone via amide bonds.
