Summary: The anticonvulsant effects of felbamate (FBM) alone or in combination with phenytoin (PHT), carbamazepine (CBZ), valproate (VPA), or phenobarbital (PB) were investigated against maximal electroshock (MES) seizures in mice. Nonprotective dose

Background and Purpose Felbamate, a novel anticonvulsant that binds to the glycine site of the N -methyl- d -aspartate receptor, has been shown to have neuroprotective properties in vitro and in vivo. In a rat pup model of hypoxia-ischemia, felbamate

Labeled 25-hydroxyvitamin D3-26,23-lactone was isolated from the serum of vitamin D-repleted rats given [3 alpha-3H]-25-hydroxyvitamin D324 hr prior to sacrifice. The metabolite was identified by cochromatography with the authentic lactone on straigh

Vitamin D-deficient rats given 25-hydroxy-26,26,26,27,27,27-hexafluorovitamin D 3 have no detectable 24,25-dihydroxyvitamin D 3 , 1,25-dihydroxyvitamin D 3 , 25,26-dihydroxyvitamin D 3 , or 25-hydroxyvitamin D 3 -26,23-lactone in their blood while th

A major vitamin D metabolite was isolated in pure form from the blood plasma of chicks either maintenance levels or large doses of vitamin D3. The isolation involved methanol-chloroform extraction and five column chromatographic procedures. The metab

To evaluate possible functional roles for 24,25-dihydroxyvitamin D3, 24,24-difluoro-25-hydroxyvitamin D3 has been synthesized and shown to be equally as active as 25-hydroxyvitamin D3 in all known functions of vitamin D. The use of the difluoro compo

Vitamin D supplemented rats produce a metabolite of 25-hydroxy[3 alpha-3H]vitamin D3 that is easily separated from known metabolites by using high-performance liquid chromatography. The production of this metabolite in vivo as well as 1,25-dihydroxyv

A primary confluent culture of epithelial cells from rat kidney has been developed. These cells possess a 3.2-3.4 S high-affinity, low-capacity binding protein for 1,25-dihydroxyvitamin D3. They metabolize 25-hydroxyvitamin D3 to at least five metabo
