Aganodine is a guanidine that activates presynaptic imidazoline receptors. Aganodine inhibits the presynaptic release of norepinephrine through its agonism at imidazoline receptors.
WAY-100135 dihydrochloride is a potent and selective antagonist of both presynaptic and postsynaptic 5-HT 1A receptors, exhibiting an IC 50 value of 34 nM specifically at the rat hippocampal 5-HT 1A receptor. This compound displays promising antipsychotic effects.
α-Synuclein (61-75) is a peptide fragment derived from the larger protein α-Synuclein. α-Synuclein is predominantly found in presynaptic nerve terminals and is considered to be a biomarker candidate for Parkinson's disease (PD).
The alpha-adrenoceptors blocking effect of (N-piperidinomethyl)-2-chromanne was studied in vivo and in vitro in the rat. In the pithed rat, (N-piperidinomethyl)-2-chromanne (1 mg kg i.v.) antagonized the pressor effects induced by alpha agonists. (N-piperidinomethyl)-2-chromanne competitively antagonized the pressor effects of M7 (alpha 2-agonist) and cirazoline (alpha 1-agonist). (N-piperidinomethyl)-2-chromanne antagonized the inhibitory effects of clonidine on presynaptic alpha 2-receptors in stimulated pithed rats.
