In the presence of R59949, vasopressin- as well as collagen-induced release reaction and aggregation was strongly increased, independently of the formation of arachidonate metabolites.
In THP‐1 monocytes, R59949 attenuates CCL2‐evoked Ca
2+
signalling with a half‐maximal concentration of 8.6 μM.
R59949 inhibits inducible nitric oxide production through decreasing transplasmalemmal L-arginine uptake in vascular smooth muscle cells.
