生物活性

Piperoxan (Benodaine) hydrochloride is an α2 adrenoceptor antagonist. Piperoxan hydrochloride is the first-generation antihistamine.

IC50 & Target

adrenoceptor[1]
體外研究
(In Vitro)

When the medulla is superfused with α2 adrenoceptor antagonist Piperoxane (50 μM; 5 min) while the pons is with artificial cerebrospinal fluid (ACSF), the three inactive preparations display rhythmic phrenic bursts at a low frequency (2-4 c/min), and the phrenic burst frequency of the 12 active ones significantly increases during the last 3 min of Piperoxane applications (163±12% of the previous mean frequency). In active medullary preparations, the effects of NA applications (25 μM; 5 min) are compared when the preparations sre superfused either by ACSF (n=8) or by the α2 adrenoceptor antagonist Piperoxane (50 μM; PIP-ACSF; n=5). NA applications either alone (NA-ACSF) or with Piperoxane (PIP-ACSF+NA) significantly increases the phrenic burst frequency. However, the blockage of the medullary α2 adrenoceptors by Piperoxane potentiates a phrenic burst frequency increase: during the fifth minute of NA applications, the phrenic burst frequency reached 171±11% of the mean control value when ACSF is applied alone and 234±21% of the mean control value when PIP-ACSF is applied in control condition[1].

Kinase Assay
[1]

The mouse neonates (P0-P3) are ether-anesthetized and decerebrated; the brain stems and the cervical spinal cords are dissected out and placed ventral sides up in a 2 mL chamber superfused with artificial cerebrospinal fluid (ACSF) at 27±0.25°C (mean±SD), renewed at a rate of 2 mL/min. The ACSF [containing (in mM) 129 NaCl, 3.35 KCl, 1.26 CaCl2, 1.15 MgCl2, 21 NaHCO3, 0.58 NaH2PO4, and 30 glucose] is oxygenated and equilibrated (pH 7.4 at 27°C) by bubbling carbogene (95% O2-5% CO2). In the pharmacological experiments, this is replaced by another ACSF in which bioreactive substances are dissolved: noradrenaline at 25 μM (NA-ACSF) or α2 adrenoceptor antagonists, either Piperoxane at 50 μM (PIP-ACSF) or yohimbine at 50 μM (YO-ACSF). In some of the experiments, a patch-clamp microelectrode (1 μm diameter tip) is lowered within the ventral pons into the A5 nucleus where a solution of either ACSF or NA (1 mM) is pressure-ejected. The ejected volume is estimated 20 nL for a pressure pulse lasting 2 s[1].

Animal Administration
[2]

Mice[2]
Male Balb-C mice are used, weighing between 20 and 25 g. In mice pretreated with the α-adrenoceptor antagonist Piperoxan, or with naloxone, both at a dose of 3×10-5 mol /kg s.c. given 15 min before the acetic acid, the antinociceptive action of (-)-isoprenaline is only slightly antagonized. Dose-ratios of 1.45 and 1.7, are produced by these two antagonists.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
