Ro 41-1049 hydrochloride is a selective, reversible, orally-active MAO-A inhibitor.Target: MAOin vivo: Ro 41-1049 is an inhibitor of the enzyme monoamine oxidase type A (MAO-A) to rats and monitored extracellular catecholamine levels in the corpus striatum before and after the intraperitoneal (IP) administration of a bolus of L-dopa. Acute administration of Ro 41-1049 (1-50 mg/kg IP) produced a dose-dependent decrease in basal levels of the dopamine metabolites 3,4-dihydroxyphenylacetic acid (DOPAC) and homovanillic acid (HVA) and an increase in basal levels of dopamine. In rats treated with Ro 41-1049 (20 mg/kg IP), L-dopa administration (100 mg/kg IP) produced a greater increase in striatal levels of dopamine than it did in controls, while DOPAC and HVA formation was attenuated. We conclude that inhibition of central MAO-A activity promotes synaptic accumulation of dopamine following administration of pharmacological doses of L-dopa.

Dihydroergotamine mesylate is an ergot alkaloid used to treat migraines.Target: 5-HT ReceptorsDihydroergotamine is not as effective as sumatriptan or phenothiazines as a single agent for treatment of acute migraine headache; however, when administered with an antiemetic, dihydroergotamine appears to be as effective as opiates, ketorolac, or valproate. Given its nonnarcotic properties, parenteral dihydroergotamine combined with an antiemetic should be considered as effective initial therapy in clinical practice [1]. The introduction of the intranasal formulation of DHE provides both pharmacologic and patient-convenience advantages for use in migraine therapy [2, 3].

TBPB is an allosteric M1 mAChR agonist(EC50=289 nM) that regulates amyloid processing and produces antipsychotic-like activity in rats.IC50 value: 289 nM(EC50) [2]Target: M1 mAChR agonistin vitro: TBPB activates M(1) through an allosteric site rather than the orthosteric acetylcholine binding site, which is likely critical for its unprecedented selectivity. Whole-cell patch-clamp recordings demonstrated that activation of M(1) by TBPB potentiates NMDA receptor currents in hippocampal pyramidal cells but does not alter excitatory or inhibitory synaptic transmission, responses thought to be mediated by M(2) and M(4) [1]. in vivo: TBPB was efficacious in models predictive of antipsychotic-like activity in rats at doses that did not produce catalepsy or peripheral adverse effects of other mAChR agonists [1].
