Journal of inorganic biochemistry, 42(4), 267-272 (1991-06-01)
The preparation and spectral properties of copper(II) complexes of two hydantoins are reported. Complexes of the general formula Cu(hyd)2(py)2, where hyd = phenytoin or nirvanol; and py = pyridine were prepared and characterized by infrared and ESR. Spectral data show

Epilepsia, 27(4), 412-418 (1986-07-01)
Stereoselective metabolism has been demonstrated for mephenytoin (MHT), R-MHT being demethylated to the pharmacologically active metabolite 5-phenyl-5-ethylhydantoin (PEH; nirvanol), and S-MHT undergoing aromatic hydroxylation to 4-OH-MHT, with formation of an intermediate arene oxide metabolite. PEH is responsible for the therapeutic

Disposition of 1-benzenesulfonyl-5,5-diphenylhydantoin (II) having a potent anti-inflammatory activity was compared with that of 5,5-diphenylhydantoin (I), an antiepileptic drug, in order to elucidate whether the pharmacodynamic difference between them can be explained by their physicochemical and pharmacokinetic properties. After oral

In vitro methods were used to identify the cytochrome P450 (CYP) enzyme(s) involved in S-mephenytoin N-demethylation. S-Mephenytoin (200 microM) was incubated with human liver microsomes, and nirvanol formation was quantitated by reversed-phase HPLC. S-Mephenytoin N-demethylase activity in a panel of

The pharmacodynamics of rat hepatic cytochrome P450 2B (P450 2B) induction by phenobarbital (PB) and two structural congeners, dl-5-ethyl-5-phenylhydantoin (EPH) and dl-5-ethyl-5-phenyloxazolidinedione (EPO), were investigated. The in vivo induction of P450 2B was probed in F344/NCr rats by measuring immunoreactive
