    "goal": "To in and inactivate HIV virus and other pathogens",
    "problem_addressed": "HIV/AIDS infection and related viral diseases",
    "concept_summary": "CSA-54 is a synthetically derived bile-acid molecule that mimics cationic antimicrobial peptides. Its positive charge electrostatically attracts it to the negatively charged viral envelope, disrupting the membrane and preventing infection of host cells.",
    "detailed_description": "Ceragenins are amphiphilic molecules built on a cholanic acid scaffold with attached amino-acid side chains, giving them a net positive charge. CSA-54, the most highly charged member of the family, binds to viral and bacterial membranes, causing depolarization and loss of integrity. In vitro studies at Vanderbilt showed that CSA-54 can inactivate multiple HIV strains and also display activity against influenza, smallpox, and herpes viruses. The compound can be formulated as a topical cream, ointment, pill, or injection, pending further development and regulatory approval.",
