Chemical Structure
Mepyramine maleate
Synonym(s): Pyrilamine maleate
- CAS No.: 59-33-6
- Formula:C21H27N3O5
- Molecular Weight:401.46
IUPAC Name: N1-(4-methoxybenzyl)-N2,N2-dimethyl-N1-(pyridin-2-yl)ethane-1,2-diamine maleate
InChIKey: JXYWFNAQESKDNC-BTJKTKAUSA-N
SMILES: CN(C)CCN(CC1=CC=C(OC)C=C1)C2=NC=CC=C2.O=C(O)/C=C\C(O)=O
Biological Activity: Mepyramine maleate (Pyrilamine maleate) is a selective histamine H1 receptor antagonist and KCNQ channel inhibitor, with an IC50 of 12.5 μM against KCNQ2/Q3. Mepyramine maleate shows no activity against allergic asthma in mice when used alone, but modulates the effect of JNJ 7777120 (HY-13508) on allergic asthma in mice; it inhibits the development of morphine physical dependence and increases histamine levels in mouse brains. Mepyramine maleate can be used in studies related to seizures, convulsions, allergic asthma and morphine physical dependence[1][2][3][4].
