生物活性

描述ST271 is a potent inhibitor of protein tyrosine kinase (PTK) with IC50s of 6.7μM, also inhibits phospholipase D activation with IC50 of 9 μM. ST271 did not inhibit Ins(1,4,5)P3 generation, but did inhibit protein tyrosine phosphorylation stimulated by fMet-Leu-Phe. ST271 does not inhibit phorbol ester-stimulated PLD, indicating that it does not inhibit PLD per se, but probably acts at a site between the receptor and the phospholipase^[1]. PLD was activated in response to 0.3 U/ml thrombin, and this activation was reduced by several of the PTK inhibitor ST271. ST271 partially inhibited peptide phosphorylation in the membrane preparation and in permeabilized platelets^[2].
