Second tributyrin has a half life of approximately 40 min with more favorable pharmacokinetic properties and is better tolerated when compared with intravenous butyrate solution.22 23 Third a direct effect on the liver by the higher hepato portal butyrate level could be expected following oral administration.23 24 Finally we hypothesized
The effects of tributyrin on circulation and respiration have been studied by injection of a tributyrin emulsion. On intravenous injection the effect of tributyrin on circulation is characterized by rapidly appearing bradycardia and a fall in blood pressure followed by a rise in blood pressure.
Tributyrin TB is a triglyceride based on glycerol which has three attached butyrate groups. As in all triglycerides the attachment of the butyric acid group is via an ester bond. It is a compound naturally found in butter and is used to make margarine. The compound is also highly stable and taken as an absorbed prodrug for butyric acid.
These observations are consistent with prior reports that intravenous injection of butyrate induces slow Tributyrin is an ester composed of three butyric acid molecules and glycerol.

Furthermore after intraperitoneal administration into mice tributyrin emulsion inhibited the formation of tumor colonies in the lung following intravenous injection of melanoma cells. Taken together our data suggests that tributyrin emulsion may be developed as a potent anti cancer agent against melanoma.

An investigation on the use of tributyrin nanoemulsions for docetaxel delivery. Tributyrin an oil with anticancer properties is a good solubilizer for docetaxel an agent used in the treatment of several cancers. In this paper the interaction between tributyrin and docetaxel was investigated in vitro in search of a potential synergistic effect.
Previously our group demonstrated that daily oral administration of the prodrug tributyrin is able to briefly achieve levels >100 μ M . Given in vitro data that differentiating activity requires continuous butyrate exposure the short t1/2 of the drug and a desire to mimic the effects of an intravenous infusion we evaluated a three times

Tributyrin NSC was supplied by the National Cancer Institute Cancer Therapy Evaluation Program. Drug was supplied as white soft gelatin capsules containing 500 mg of tributyrin without additives. Drug treatment Cohorts of at least three patients were entered at each dose level as previouslydescribed 2 .Asnodose
Tributyrin an oil with anticancer properties is a good solubilizer for docetaxel an agent used in the treatment of several cancers. In this paper the interaction between tributyrin and docetaxel was investigated in vitro in search of a potential synergistic effect. Then nanosized emulsions ca. 100 nm combining both tributyrin and docetaxel were developed and tested for their cell growth
Tributyrin a butyrate prodrug is capable of delivering butyrate to the stomach and bloodstream allowing for efficient delivery of anti inflammatory metabolic improving and neuroprotective effects. This is what makes NewBiome the next generation of gut health supplements.
Tributyrin is an active differentiating and cytotoxic agent available for clinical testing in human prostate cancer. Here we report for the first time that tributyrin like butyric acid has differentiating and cytotoxic effects and induces cell cycle arrest as well as apoptosis in 3 phenotypic and genotypic divergent human prostate cancer cell lines.
Tributyrin is a prodrug of butyrate and overcomes many of the problems of the parent compound. It is a triglyceride containing three butyrate molecules esterified to glycerol Fig. 1 . Most importantly the drug can be administered orally.

When injected intravenously into mice as a nanoemulsion the docetaxel/tributyrin combination displayed extreme toxicity. Therefore the current data preclude its combination with docetaxel in nanoemulsions for intravenous administration.
Intravenous sodium butyrate doses were 0.31 0.62 0.94 and 1.25 g/kg. Oral sodium butyrate was given to mice at 5 g/kg. Subsequently similar studies were performed in female Sprague Dawley rats. Rats were given tributyrin by oral gavage at doses of 3.6 5.2 or 10.3 g/kg or sodium butyrate i.v. at a dose of 500 mg/kg.
The in vivo results show that the 4 fluorophenyl carbamate 8 and the 4 methoxyphenyl carbamate 9 in this series had the best anti PCP activity by both intravenous and oral administration at a dosage level of 22 mol and 33 μmol/kg/day respectively. Compounds 3−7 were also more active than the parent drug 1 on oral administration.
Tributyrin provides an efficient means to deliver butyrate to systemic circulation for a sustained duration Egorin et al. 1999 .
