FIDUXOSIN性质、用途与生产工艺
Fiduxosin 是一种 α1-adrenoceptor 拮抗剂,对 α1a-adrenoceptor,α1b-adrenoceptor 和 α1d-adrenoceptor 的 Ki 值分别为 0.160 nM,24.9 nM 和 0.920 nM。
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)
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.
Fiduxosin (30, 100, and 300 μg/kg, i.v.) antagonizes IUP responses to i.v. EPI in anesthetized dogs. Fiduxosin (178, 592, and 1780 μg/kg, i.v.) elicits transient effects on blood pressure, with no effect of the lowest dose on MAP in spontaneously hypertensive rats (SHR). Fiduxosin (3 μmol/kg or 1780 μg/kg i.v.) slightly reduces MAP, but head-up tilt causes further diminution of MAP at only the 15-min observation with minimal additional changes in MAP at times ≥30 min postdosing in SHR. Fiduxosin (0.1, 0.3, 1.0, and 3.0 mg/kg p.o.) blocks prostatic intraurethral pressure (IUP) responses to a greater extent than MAP responses. The IUP ED
50
values of fiduxosin is 0.24 mg/kg.
