Biochem/physiol Actions

A fungal metabolite possessing potent immunosuppressive properties. It inhibits the T-cell receptor signal transduction pathway via the formation of cyclosporin A−cyclophilin complex that inhibits calcineurin (protein phosphatase 2B). Inhibits nitric oxide synthesis induced by interleukin 1α, lipopolysaccharides and TNFα. Can block cytochrome c release from mitochondria.

The vacuolar-type H+-ATPase (V-ATPase) is a multi-subunit proton pump that regulates cellular pH. V-ATPase activity modulates several cellular processes, but cell-type-specific functions remain poorly understood. Patients with mutations in specific V-ATPase subunits can develop sensorineural deafness, but the underlying mechanisms

A library of chalcones with basic functionalities were screened for inhibition of P-glycoprotein (Pgp, ABCB1) by the calcein-AM accumulation assay on MDCKII/MDR1 cells. Three members that had ring A substituted with 5-(1-ethylpiperidin-4-yl) and 2,4-dimethoxy groups were found to increase calcein-AM
