Chemical Structure
Dexbrompheniramine
Synonym(s): (+)-Brompheniramine; (S)-Brompheniramine
- CAS No.: 132-21-8
- Formula:C16H19BrN2
- Molecular Weight:319.24
IUPAC Name: (S)-3-(4-bromophenyl)-N,N-dimethyl-3-(pyridin-2-yl)propan-1-amine
InChIKey: ZDIGNSYAACHWNL-HNNXBMFYSA-N
SMILES: CN(C)CC[C@H](C1=CC=CC=N1)C2=CC=C(C=C2)Br
Biological Activity: Dexbrompheniramine ((+)-Brompheniramine; (S)-Brompheniramine) is a dual inhibitor of histamine H1 receptor and TRPV1 receptor that can cross the blood-brain barrier. Dexbrompheniramine exerts its effects by functionally blocking H1 receptor activity and dose-dependently inhibiting TRPV1-mediated calcium responses, including Capsaicin (HY-10448)-induced responses. The combination of Dexbrompheniramine with Cimetidine (HY-14289) eliminates histamine-induced and sham-feeding-induced drinking behavior, whereas Dexbrompheniramine alone does not induce thirst or alter sham-feeding behavior in rats. Dexbrompheniramine can be used in the research of chronic cough and related pathological mechanisms[1][2][3].
