Acetylation, deacetylation and hydroxylation of sulphamethoxazole and N4-acetylsulphamethoxazole in the turtle Pseudemys scripta elegans.
The turtle Pseudemys scripta elegans is able to hydroxylate and acetylate Sulphamethoxazole in a way that is comparable to man, i.e. the rate and yield of hydroxylation equals that of the acetylation. The hydroxy metabolites 5-hydroxy- and N4-acetyl-5-hydroxysulphamethoxazole are not glucuronidated. N4-acetylsulphamethoxazole is neither deacetylated nor hydroxylated.
