Biochem/physiol Actions

Pyr3 is a pyrazole compound that potently and selectively antagonizes TRPC3. Pyr3 inhibits TRPC3 by binding to the extracellular side of the receptor, resulting in suppression of B cell activation and cardiac hypertrophy.

Members of the canonical transient receptor potential (TRPC) channel family are ion channels which conduct Ca+2 and are activated by membrane receptor-mediated stimulation of phospholipase C (PLC) activity. However, TRPC3 and other family members are also activated by membrane-independent diacylglycerol (DAG). BTP1 and BTP2 are pyrazoles that block TRPC channels, but they are not specific for TRPC subtypes. This channel is implicated in various processes, including B cell receptor (BCR)-mediated Ca+2 oscillations, activation of nuclear factor of activated T cells (NFAT), and promotion of cardiac hypertrophy.

Inspiratory breathing movements depend on pre-Bötzinger complex (preBötC) interneurons that express calcium (Ca2+)-activated nonselective cationic current (ICAN) to generate robust neural bursts. Hypothesized to be rhythmogenic, reducing ICAN is predicted to slow down or stop breathing; its contributions to motor

Acute pancreatitis (AP) is a common digestive disease without specific treatment, and its pathogenesis features multiple deleterious amplification loops dependent on translation, triggered by cytosolic Ca2+ ([Ca2+]i) overload; however, the underlying mechanisms in Ca2+ overload of AP remains incompletely understood.
