Drug metabolism and disposition: the biological fate of chemicals, 28(6), 672-679 (2000-05-23)
A CBV [(-)-carbovir, (-)-carbocyclic 2',3'-didehydro-2', 3'-dideoxyguanosine] prodrug, 6AC [(-)-6-aminocarbovir, (-)-carbocyclic 2',3'-didehydro-2', 3'-dideoxy-6-deoxy-6-aminoguanosine], was previously evaluated in rats, and it exhibited superiority to the parent drug in increasing systemic and central nervous system exposure to CBV. The gut wall was determined...

Drug metabolism and disposition: the biological fate of chemicals, 19(2), 462-466 (1991-03-01)
The potential for the metabolic conversion of (-)-6-aminocarbovir to (-)-carbovir, a potent reverse transcriptase inhibitor effective against human immunodeficiency virus, has been examined in male Sprague-Dawley rats. Plasma (-)-6-aminocarbovir concentrations declined rapidly in a biphasic manner following an iv bolus...

Drug metabolism and disposition: the biological fate of chemicals, 27(1), 113-121 (1999-01-12)
Several in vitro and in situ approaches were used to determine the dominant presystemic activation site for (-)-6-aminocarbovir, (-)-carbocyclic 2',3'-didehydro-2', 3'-dideoxy-6-deoxy-6-aminoguanosine (6AC) conversion in rats. The in vitro disappearance half-lives (mean +/- S.D.) in the cytosolic fractions obtained from homogenates...
Lack of effect of catheterization on the pharmacokinetics of (-)-carbovir in rats.

Drug metabolism and disposition: the biological fate of chemicals, 20(1), 47-51 (1992-01-01)
The recently synthesized carbocyclic 2',3'-didehydro-2',3'-dideoxy-6-deoxy-6-amino-guanosine [(-)6AC] was evaluated as a prodrug for carbovir, carbocyclic 2',3'-didehydro-2',3'-dideoxyguanosine [(-)CBV] in seven male Sprague-Dawley rats. A randomized three-way cross-over design was used. Rats were assigned to receive the following treatments: a 20 mg/kg (-)6AC...

Evaluate the ability of (-)-6-aminocarbovir ((-)-6AC) to improve the CNS exposure to (-)-carbovir ((-)-CBV). Activation of (-)-6AC in vitro was assessed by incubations of rat brain tissue homogenates. The in vivo brain exposure to (-)-CBV was then examined in rats...
Evaluation of gastrointestinal absorption and metabolism.
