cinanserin, methiothepin, cyproheptadine, spiperone.
10 mM 5-HT stock solutions were made in 0.1 M acetic acid solutions and stored at 4℃.
methiothepine blocked AC-coupled 5-HT receptors.
spiperone (100microM) blocks PKC-dependent modulatory effects of 5-HT, which is the facilitation from the depressed synapse.
spiperone is a selective antagonist of PLC-coupled 5-HT receptors in Aplysia.
Staurosporine is the PKC blocker.
