Description
IC50 & Target
Ki: 0.16 nM (α1a-adrenoceptor), 24.9 nM (α1b- adrenoceptor), 0.92 nM (α1d-adrenoceptor), 92 nM (Human α2a-adrenoceptor), 22 nM (Human α2c-adrenoceptor), 21 nM (Rat α2b-adrenoceptor), 29 nM (Rat 5HT1A receptor)[1]
In Vitro
Fiduxosin displays low affinity for other adrenoceptors, including cloned human α2a- (92 nM) and α2c-adrenoceptors (22 nM) and rat neonatal lung α2b-adrenoceptors (21 nM), in addition to β-adrenoceptors (2-5 μM). Fiduxosin also has low affinity for 5HT1A receptors in rat cortex (29 nM) compared with its affinity at α1a-adrenoceptors (0.16 nM). Fiduxosin antagonizes competitively PE-induced responses with a pA2 value of 7.58, in the rabbit urethra[1].
