生物活性

Mepyramine maleate, a first generation antihistamine, is an antagonist of histamine H1 receptor, with Kds of 0.8 nM, 5200 nM and >3000 nM for H1, H2, and H3 receptor, respectively, and a pKd of 9.4 for H1 receptor.

IC50 & Target

Kd: 0.8 nM (Histamine H1 receptor), 5200 nM (Histamine H2 receptor), >3000 nM (Histamine H3 receptor)[1]
pKd: 9.4 (Histamine H1 receptor)[2]
体外研究
(In Vitro)

Mepyramine maleate is an antagonist of histamine H1 receptor, with Kds of 0.8 nM, 5200 nM and >3000 nM for H1, H2, and H3 receptor, respectively[1], and a pKd of 9.4 for H1 receptor[2]. Mepyramine binds to the H1 receptor with different Kds in Guinea pig brain (0.8 nM), rat brain (9.1 nM) and DDT1-MF-2 and BC3H1 cell (276 nM)[1]. Mepyramine decreases the InsP levels in CHO-gpH1 cells, with log EC50 of -7.94 ± 0.11, and reduces the the maximal response to ATP in CHO-gpH1 cells[3].

[3]

Briefly, cells are seeded in 24-well cluster dishes and cultured for 24 h (70-80% confluence) in DMEM. Cells are then washed, and the medium is replaced for DMEM without calf serum plus the addition of myo-[3H]inositol (2 μCi/mL) and cultured for 24 h. Thereafter, the medium is aspirated and replaced with DMEM without calf serum containing 10 mM LiCl and incubated for 20 min. Cells are then stimulated for 20 min with histamine in concentrations ranging from 1 nM to 100 μM in a final volume of 300 μL in the presence or absence of [3H]inositol the concentrations indicated in each particular experiment. The incubation is stopped by the addition of 900 μL of cold chloroform, methanol, 0.12 M HCl (1:2:1 v/v, freshly prepared), and phases are split by the addition of 300 μL of water and 300 μL of chloroform. The mixture is then centrifuged at 1500 × g for 10 min, and the total water-soluble inositol phosphate fraction is purified by anion exchange chromatography. Radioactivity of the eluted fractions is measured using a liquid scintillation counter. Results are expressed as the ratio obtained when total [3H]inositol phosphate radioactivity is normalized to total [3H]inositol radioactivity recovered from the initial water wash of the columns[3].

Animal Administration
[4]

Rats[4]
Healthy adult male albino Wistar rats weighing 200-220 g are maintained in polypropylene cages with 6 rats in each cage with food and water available ad libitum. Mepyramine is dissolved in normal saine. Mepyramine at doses of 5, 10, and 20 mg/kg and intraperitoneally injected 30 min before induction of nociception. Physostigmine at doses of 0.05, 0.1, and 0.2 mg/kg, and atropine at a dose of 2 mg/kg, are subcutaneously administered 20 and 40 min before induction of formalin-induced pain, respectively. Atropine (2 mg/kg, s.c.) is injected 20 min before subcutaneous injection of physostigmine (0.1 mg/kg). In combined treatment, intraperitoneal injections of mepyramine (10 mg/kg) and famotidine (20 mg/kg) are performed 10 min before physostigmine (0.1 mg/kg, s.c.) and 10 min after atropine (0.2 mg/kg, s.c.) administrations. Drug solutions are intraperitoneally injected in a volum of 1 mL/kg, using a 25-gauge injection needle. Subcutaneous injections of drug solutions are perfoemed in a constant volume 0.2 mL per rat at the neck region using a 27-gauge injection needle[4].

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.
