Tributyrin (Glyceryl tributyrate), a neutral short-chain fatty acid triglyceride, is a stable and rapidly absorbed prodrug of Butyric Acid. It diffuses through biological membranes and is metabolized by intracellular lipases, releasing effective butyrate directly into cells in vivo, exhibiting potent proapoptotic, antiproliferative, and differentiation-inducing effects.

Dextran sulfate sodium salt (MW 4500-5500) is an anhydrous glucose polymer with a molecular weight range of 4500-5500. It inhibits human immunodeficiency virus replication by preventing viral adsorption to host cells and is commonly used to model inflammatory bowel disease. The high negative charge from its sulfate groups damages the intestinal mucosal barrier, leading to intestinal barrier dysfunction, macrophage impairment, and bacterial flora disorder.

Stavudine (BMY-27857), a nucleoside reverse transcriptase inhibitor analog of thymidine, has activity against HIV.

Sodium 4-phenylbutyrate (TriButyrate), a transcriptional regulator, reversibly inhibits class I and II histone deacetylases (HDACs )resulting in a global increase in gene expression, decreased cellular proliferation, increased cell differentiation, and the induction of apoptosis in susceptible tumor cell populations.
