Structure–Activity Relationship, Drug Metabolism and Pharmacokinetics Properties Optimization, and <i>in Vivo</i> Studies of New Brain Penetrant Triple T-Type Calcium Channel Blockers
availability of numerous antiepileptic drugs, 20–30% of epileptic patients are pharmacoresistant with seizures not appropriately controlled. Consequently, new strategies to address this unmet medical need are required. T-typecalciumchannels play a key role in neuronal excitability and burst firing, and selective tripleT-typecalciumchannelblockers could offer a new way to treat various CNS disorders
The present invention if directed to certain cinnoline compounds that are PDE10 inhibitors, pharmaceutical compositions containing such compounds and processes for preparing such compounds. The invention is also directed to methods of treating diseases mediated by PDE10 enzyme, such as obesity, non-insulin dependent diabetes, schizophrenia, bipolar disorder, obsessive-compulsive disorder, and the like.
