| Introduction: The human EP1 (hEP1) prostanoid receptor is a G-Protein Coupled Receptor
(GPCR) which plays important physiological roles in some systems in the body like cardiovascular
and immune systems and could be a very important target for drug design.
Materials and methods: To understand the molecular structure of hEP1 receptor, a homology
model of the receptor was constructed from the 2.4 Å resolution crystal structure of human β
adrenergic
receptor
(PDB
code:
2RH1),
using
three
different
sequence
alignments.
The
model
including
PGE
inside the active site was subjected to molecular dynamics simulation. Docking
studies were performed for PGE
2
and 10 prostanoid analogs in the active site of the modeled
receptor.
Results and Discussion: The structure of modeled receptor remained stable during the 10
nanosecond(ns) simulation. In the docking simulations a correlation of r
2
=0.74 was observed
between the K
i
2
values and the docking scores of the prostanoid compounds. The structure which
was modeled in the present study can be used in the structure-based drug design, helping the
rational design of novel ligands for the hEP1 receptor.
