Temanogrel is a highly selective 5-HT2A receptor antagonist with a Ki of 4.9 nM.
Temanogrel is a highly selective 5-HT2A receptor antagonist with a Ki of 4.9 nM. Temanogrel inhibits inositol phosphate accumulation with an IC50 of 5.2 nM. Temanogrel exhibits potent inhibition of serotonin mediated amplification of ADP-stimulated human and dog platelet aggregation (IC50=8.7 and 23.1 nM, respectively)[1]. Pretreatment of aortic rings with Temanogrel prevents the vasoconstriction caused by 20 μM 5-HT in a concentration-dependent manner. Preincubation with Temanogrel also significantly inhibits the 5-HT-stimulated DNA synthesis with an IC50 of 13±7 nM[3].
There are no differences in heart rate or mean arterial pressure between saline-treated and Temanogrel-treated groups at any time during the experiment (that is, for mean arterial pressure, P=0.508 between groups, and P=0.540 for group-time interaction). In dogs assigned to receive Temanogrel, plasma Temanogrel levels show a rapid and sustained increase, averaging 25.5±4.1, 28.7±4.6 and 31.2±4.5 ng/mL, respectively, at 10 min, 1.25 h and 2.25 h after the start of treatment[3].

Cell experiment: | To provide further insights into the effect of Temanogrel on platelet-dependent clot formation in models devoid of vascular smooth muscle, two in vitro post hoc experiments are performed. Paired aliquots of heparinized whole blood are incubated with Temanogrel (100 nM) or vehicle for 10 min at 37°C, and then placed in a thromboelastogram (TEG) pin-and-cup system with 10 µm serotonin, reptilase, and activated factor XIII (n=3 paired samples). The maximum amplitude of torsion is quantified for all samples. Aliquots of citrated blood (n=3 pairs) are incubated with Temanogrel (100 nM) or vehicle for 10 min at 37°C, and then pipetted into collagen-ADP cartridges. For each sample, the time (in seconds) required for the complete platelet-mediated thrombotic occlusion of the membrane aperture is recorded[2]. |
Animal experiment: | in vivo study.--> Adult male beagle dogs (n=3) are used and receive a single oral gavage dose of Temanogrel at 10 mg/kg. Temanogrel is formulated in sterile water at 5 mL/kg. Animals are fasted before Temanogrel delivery. Serial sampling is used to obtain plasma concentration versus time profiles. Whole blood samples are collected via jugular vein venipuncture over a 24-h period. Plasma is prepared by centrifugation from sodium heparin-treated whole blood, frozen, and stored at approximately -20°C until bioanalytical analysis[3]. |
