“…The former technique allows for the direct detection of COU potentially produced in situ. The latter is a useful screening tool for studying the digestive absorption and metabolic behavior of substances introduced in the various parts of the gastrointestinal tract (10). In addition, this last technique allows the CA4H activity of recombinant yeasts to be tested using the lowest nontoxic dose of CIN (7 mol).…”

An innovative "biodrug" concept, based on the oral administration of living recombinant microorganisms, has recently emerged for the prevention or treatment of various diseases. An engineered Saccharomyces cerevisiae strain expressing plant P450 73A1 (cinnamate-4-hydroxylase [CA4H] activity) was used, and its survival and ability to convert trans-cinnamic acid (CIN) into p-coumaric acid (COU) were investigated in vivo. In rats, the recombinant yeast was resistant to gastric and small intestinal secretions but was more sensitive to the conditions found in the large intestine. After oral administration of yeast and CIN, the CA4H activity was shown in vivo, with COU being found throughout the rat's digestive tract and in its urine. The bioconversion reaction occurred very fast, with most of the COU being produced within the first 5 min. The gastrointestinal sac technique demonstrated that the recombinant yeast was able to convert CIN into COU (conversion rate ranging from 2 to 5%) in all the organs of the rat's digestive tract: stomach, duodenum, jejunum, ileum, cecum, and colon. These results promise new opportunities for the development of drug delivery systems based on engineered yeasts catalyzing a bioconversion reaction directly in the digestive tract.

“…The SM·HCl (90 mg/ kg) significantly improves the bioavailability of paeoniflorin in rats (Liu et al, 2005a), while coadministration of paeoniflorin does not affect the pharmacokinetic parameters and tissue distribution of sinomenine (Liu et al, 2005b). The mechanism is suggested that sinomenine decreases the efflux transport of paeoniflorin by P-glycoprotein (Chan et al, 2006).…”
