Bioactivity | Ciproxifan (FUB 359) hydrochloride is a potent, selective, orally bioavailable and competitive antagonist of histamine H3-receptor, with an IC50 of 9.2 nM. Ciproxifan hydrochloride displays low apparent affinity at other receptor subtypes. Ciproxifan hydrochloride can be used for the research of aging disorders and Alzheimer's disease[1][3]. |
Invitro | Ciproxifan hydrochloride inhibits [3H]HA release from synaptosomes of rat cerebral cortex, with a Ki of 0.5 nM[1].Ciproxifan hydrochloride (0.01 nM-1 μM; 60 min) inhibits the binding of [125I]iodoproxyfan with rat striatal membranes, with a Ki of 0.7 nM[1]. MCE has not independently confirmed the accuracy of these methods. They are for reference only. 0 --> Ciproxifan hydrochloride 相关抗体: |
In Vivo | Ciproxifan hydrochloride (1 mg/kg; a single p.o.) increases the t-MeHA level in mouse brain, with an ED50 of 0.14 mg/kg[1].Ciproxifan hydrochloride (3 mg/kg, i.p.) improves the accuracy of responding in the five-choice task in rats only when the stimulus duration was 0.25 sec instead of 0.50 sec[1].Ciproxifan hydrochloride (0.15-2 mg/kg; p.o.) induces marked signs of neocortical electroencephalogram activation manifested by enhanced fast-rhythms density and an almost total waking state in cats[1].Ciproxifan hydrochloride (1 mg/kg; a single i.v.) decreases the H3-receptor ligand concentration in serum in mice, with the half-lives (t1/2) of 13 and 87 min for the distribution and elimination phases in mice, respectively[1].Ciproxifan hydrochloride (1 mg/kg; a single p.o.) exhibits oral bioavailability (F=62%) and maximal concentration (Cmax=420 nM) in mice[1]. MCE has not independently confirmed the accuracy of these methods. They are for reference only. |
