To attempt to block TRAP6 mediated Ca2+ mobilization in human pericytes. Its lack of potency and low solubility means it was not especially effective even with sub-maximal agonist concentrations - some antagonism or slowing of response - but not the complete block I had hoped for even when pre-equilibrated prior to agonist activation. We will now save our pennies to try the more potent SCH PAR1 antag
Really could not get this to dissolve at 10 mM in DMSO as website suggests - probably goes in around 7 mM. As this is not a very potent antagonist you will need to have quite a bit of DMSO around to get even partial antagonism.
