Biochem/physiol Actions

Z944 is an orally available, state-dependent, potent and selective T-type calcium channel blocker (hCav3.1/Cav3.2/Cav3.3 IC50 by voltage clamp = 50/160/110 nM under ~30% inactivated state & 130/540/260 nM in the closed state) over non-T-type voltage-gated channels (rCaV2.2 IC50 = 11 μM/30% inactivated & 150 μM/closed; hERG/rCaV1.2/hNaV1.5 IC50 = 7.8/32/100 μM). Z944 effectively suppresses seizure activity in the GAERS (absence epilepsy rats from Strasbourg) model in vivo (10-30 mg/kg qod ip.) with no adverse cardiovascular effects or neurotoxicity.

Currently available antipsychotics are unsatisfactory given their side effects and limited efficacy for the cognitive symptoms of schizophrenia. Many currently available drugs, such as haloperidol, are T-type calcium channel antagonists in addition to their well-established antagonism of dopamine D2 receptors.

Cholinergic vagal nerves projecting from neurons in the brain stem nucleus ambiguus (NAm) play a predominant role in cardiac parasympathetic pacemaking control. Central adrenergic signaling modulates the tone of this vagal output; however, the exact excitability mechanisms are not fully

Neuropeptide substance P (SP) is produced and released by a subset of peripheral sensory neurons that respond to tissue damage (nociceptors). SP exerts excitatory effects in the central nervous system, but peripheral SP actions are still poorly understood; therefore, here

Childhood absence epilepsy (CAE) is associated with interictal co-morbid symptoms including abnormalities in social behaviour. Genetic Absence Epilepsy Rats from Strasbourg (GAERS) is a model of CAE that exhibits physiological and behavioural alterations characteristic of the human disorder. However, it
