Stereoselective degradation of carprofen glucuronides under different conditions and the inﬂuence of HSA were vigra vegetal review characterized by our group. In each of those studies potential interference from stereoselective degradation of acyl glucuronides was minimized by rapid sample quenching, lowering the incubation pH to 4.7, or addition of speciﬁc esterase and β-glucuronidase inhibitors to prevent the enzymatic hydrolysis of acyl glucuronides. In studies with benoxaprofen (33), ﬂunoxaprofen (42), carprofen (45), naproxen (64), ketoprofen (29), and fenoprofen (52), the apparent ﬁrst-order degradation half-lives of the (S)-acyl glucuronides were approximately twofold longer than those of their corresponding (R)-acyl glucuronides in a proteinfree buffer system at pH 7.5, 17°C (Table 3).
When (R)- and (S)-carprofen glucuronides were incubated at pH 5.0, 5.5, and 9.0 at 17°C in phosphate buffer, degradation was highly stereoselective at pH 6.0. When HSA was added to the incubation medium, the stability of -glucuronide was decreased, whereas the apparent half-life of -glucuronide increased. As summarized in Table 3, stereoselectivity decreased while degradation velocity increased with higher pH.
The -glucuronide conjugate of carprofen degraded more rapidly than the -glucuronide, at all pH values. In addition to stereoselective acyl glucuronidation, degradation of the diastereomeric acyl glucuronides (including hydrolysis and acyl migration) of various chiral carboxylic acids has also been shown to be stereoselective (102). The effect of fatty-acid-free HSA was much greater than Table 2 Degradation Half-Lives of Carprofen β-1-O-Acyl Glucuronides, interestingly.
