Mass spectrometric identification of urinary and plasma metabolites of 6-(6'-carboxyhexyl)-7-n-hexyl-1,3-diazaspiro-[4-4]-nonan-2,4-dione, a new cytoprotective agent.

The compound IBI-P-01028, or R,S-cis-6-(6'-carboxyhexyl)-7-trans-n-hexyl-1,3-diazaspiro-[4-4]-nona n-2,4- dione, is a new cytoprotective agent under development. To study the metabolites of this compound in laboratory animals, we administered it to dogs and rats, and analyzed extracts from dog and rat urine, and from dog plasma, by GC-MS. The metabolic profiles were different in the rat and dog. In the dog (plasma and urine), one metabolite was found, and in the rat urine two other metabolites were found. The unmetabolized drug was found only in the dog plasma and urine.

Identification of microsomal metabolites of spirogermanium.

In the present study we report on the identification of two novel microsomal metabolites of the investigational anticancer agent Sprigermanium (NSC-192965). The two metabolites were isolated after incubation of Spirogermanium with fortified rat liver microsomes. Mass spectrometry studies indicate that one of them, formed in major quantities, is hydroxy Spirogermanium. The other metabolite appears to correspond to bis-desmethylated Spirogermanium.
