Description:
Background: Oral contraceptives are very widely used agents to check unwanted pregnancies.
They contain synthetic analogues of estrogen and progesterone hormones. Estrogen is an
important hormone that plays a significant role in menstrual cycle, ovulation, fertilization and
implantation. Estrogen receptor ? (ER?) can modulate the ovulation, fertilization or receptivity
of the uterus. Oral contraceptives pose mild to severe adverse effects such as menstrual cycle
disorders, metabolic alterations and increased risk of cancers. It is essential to identify and
screen alternative contraceptives that are safer to use. The present study was aimed at identifying
the compounds from Cissampelos pareira that is traditionally used for antifertility activity.
Methods: The compounds reported from the plant were collected and prepared using the
LigPrep wizard. The protein, ER? was selected from protein data bank (1G5O) and prepared.
The ligands were docked with the protein and the hits were selected for further screening of
free energy calculation, induced fit docking and molecular dynamics simulations based on the
respective scores and various interactions.
Results: Among various compounds, Coclaurine and Norruffscine have been identified to
interact with ER? and possess similar interactions as that of the endogenous ligand, estradiol.
The compounds also showed drug-like properties in Qikprop analysis and promising result in
the molecular dynamics simulation studies.
Conclusion: Considering the dock scores, molecular interactions with the ER? receptor and
energy calculations, the compounds Coclaurine and Norruffscine were found to have good
binding properties. Further in vitro and in vivo evaluations are warranted for confirmation.
