The pharmacokinetics of seven butyric esters derived from monosaccharides were studied after iv administration of a bolus dose to rabbits. Results obtained showed that a constant plasma level of butyric acid is maintained due to the slow disappearance of butyric acid esters from the plasma in contrast to the case of salts, such as arginine butyrate, which are rapidly cleared. The maintenance of these covalent compounds in the body can increase concentrations of n-butyric acid in the tumor area for more efficient chemotherapy. These results seem to be directly related to the in vitro anticellular activity of butyric esters and the prolonged therapeutic protection in tumor-bearing animals.
