Background

Vinconate is an indolonaphthyridine derivative and can stimulate the muscariic acetylcholine receptor.

Treatment with Vinconate (50 to 200 mg/kg p.o.) significantly increases dopamine concentrations in dialysate. Daily treatment with Vinconate (25 mg/kg) for 7 days also significantly increases dopamine and serotonin concentrations in dialysate[1]. Chronic treatment with Vinconate at a 10 mg/kg significantly ameliorats the reduction in [3H]QNB binding in the nucleus accumbens and cerebellum. Furthermore, this Vinconate treatment significantly enhances [3H]QNB binding in the frontal cortex and hippocampus compare with the vehicle-treated aged animals. Also, chronic treatment with Vinconate at the higher dose significantly elevates [3H]QNB binding in the hippocampal CA3 sector and dentate gyrus compare with the vehicle-treated aged animals. Chronic treatment with Vinconate at a dose of 10 mg/kg shows a significant reduction in [3H]HC binding only in the hippocampal CA1 sector compare with the vehicle-treated aged rats[2].

Protocol

Animal experiment:

344 male rats, 6 months (adult) and 24 months (aged) of age, are allowed food and water ad lib throughout the experiments. Rats are divided into four groups; (1) 6-month-old; (2) vehicle (distilled water) is administered intraperitoneally (i.p.) once a day for 4 weeks before decapitation; (3) Vinconate at a dose of 10 mg/kg is administered i.p. once a day for 4 weeks before decapitation; (4) Vinconate at a dose of 30 mg/kg is administered i.p. once a day for 4 weeks before decapitation. Rats in groups (2) to (4) are 24 months old. Each group contains 6 to 7 rats. In addition, there are no significant differences among the three aged animal groups in body weight after drug or vehicle treatment[2].
