    • Since 1 and 12 are structurally related, we have studied whether 1 may be generated after the systemic administration of 12. Thus, 5 mg/kg of 12 was administered intravenously to male Sprague-Dawley rats (250-280 g) and 0.25 mL of blood was collected at various times up to 120 min. Plasma was collected and an aliquot (0.15 mL) was deproteinated by the addition of 0.3 mL acetonitrile. An aliquot of the supernatant (0.35 mL) was evaporated to dryness under a stream of nitrogen and the residue was reconstituted by the addition of 0.1 mL of mobile phase (water/methanol/acetonitrile=20:40:40). An aliquot of the mixture was injected directly onto the LC-MS system. Although both 1 and 12 could be readily quantified by the LC-MS system, the concentration of 12, but not 1, was detected in the sample. Since we could not have detected any conversion of 12 into 1, we conclude that the action of 12 cannot be explained by its conversion to 1 in vivo.
