Kazinol B

99624-27-8 |
Kazinol B, a natural product isolated and purified from the barks of Broussonetia papyrifera, inhibits the NO synthesis with an IC(50) of 21.6 mM, stimulates respiratory burst, is probably mediated by the synergism of PKC activation and [Ca2+]i elevation in rat neutrophils, stimulates Ca(2+) release from internal Ca(2+) store, probably through the sphingosine 1-phosphate and IP(3) signaling, activates external Ca(2+) influx mainly through a non-store-operated Ca(2+) entry (non-SOCE) pathway, and inhibits SOCE, probably attributable to a break in the Ca(2+) driven force of mitochondria. |
