title: Interaction of active compounds from Aegle marmelos CORREA with histamine-1 receptor.
abstract: The aim of this study is to determine the affinity of six active compounds of Aegle Marmelos Correa, they are (E, R)-Marmin, skimmianine, (S)-aegeline, aurapten, zeorin, and dustanin as antihistamines in histamine H1 receptor in comparison to cetirizin, diphenhydramine and chlorpheniramine as ligands comparison. Previously, in the in vitro study marmin obviously antagonized the histamine H1 receptor in a competitive manner.
  
  
  METHODS
  molecular docking to determine the interaction of ligand binding to its receptor. Lower docking score indicates more stable binding to that protein.
  
  
  RESULTS
  Marmin, skimmianine, aegeline, aurapten, zeorin, and dustanin were potential to develop as antihistamine agents, especially as histamine H1 receptor antagonists by interacting with amino acid residues, Asp107, Lys179, Lys191, Asn198, and Trp428 of histamine H1 receptor.
  
  
  CONCLUSIONS
  Based on molecular docking, Amino acid residues involved in ligand protein interactions were Asp107, Lys179, Lys191, Asn198, and Trp428.
