Background:

Butyric acid-d7 is intended for use as an internal standard for the quantification of sodium butyrate by GC- or LC-MS. Butyric acid is a short-chain fatty acid.[1] It is produced predominately by bacterial fermentation of dietary fiber in the colon but has also been identified in mammalian milk.[1],[2] Butyric acid is an inhibitor of histone deacetylase (HDAC; IC50 = 90 μM in a cell-free assay).[3] It induces differentiation, cell cycle arrest at the G0 phase, and apoptosis, as well as inhibits proliferation, in a variety of cancer cells when used at concentrations ranging from 0.6 to 100 mM.[2],[5],[6] Butyric acid decreases the expression of IFN-γ-related signaling genes and metastatic genes in H460 human lung cancer cells when used at a concentration of 2 mM.[5] It reduces tumor growth in a CaSki mouse xenograft model when administered at doses of 200 and 800 mg/kg per day.[4] Butyric acid also reduces increases in colonic TNFa and Il6 expression and decreases colonic goblet cell depletion, tissue damage, muscle thickening, and cellular infiltration in a wild-type, but not Hcar2-/-, mouse model of TNBS-induced colitis.[7]
