beta carboline/vomiting

The convulsant properties of methyl beta-carboline-3-carboxylate (beta-CCM), which is a homologue of a putative benzodiazepine receptor ligand in the mammalian central nervous system, were examined in cats. Subcutaneous injection of 0.5 mg/kg of the beta-CCM produced various degrees of myoclonic

Specific serotonin receptor agonists and antagonists are marketed with respect to various diseases, most prominently severe emesis. To identify new chemical classes with affinity for the serotonin 5-HT3 channel, several compounds were synthesized which can be structurally classified as

Beta-carboline alkaloids harmine, harmaline, and tetrahydroharmine can stimulate the central nervous system by inhibiting the metabolism of amine neurotransmitters, or by direct interaction with specific receptors; they are found in numerous plants, including Peganum harmala, Passiflora incarnata

Acute i.m. injections of benzodiazepine receptor ligands were administered to baboons before 1-h observational sessions. The agonist midazolam produced sedative effects, the antagonist flumazenil produced no behavioral effects, the inverse agonist FG7142 produced tremor and the inverse agonist

The behavioral effects of abecarnil, a beta-carboline which has been suggested to function as a partial and/or selective agonist at the benzodiazepine receptor, were assessed in baboons. In a chronic administration study, 100mg/kg/day abecarnil for 6-8 weeks produced few signs of sedation: lip droop
