QSAR analysis of indazole estrogens as selective beta-estrogen receptor ligands: rationalization of physicochemical
1Department of Pharmaceutical Chemistry, B.R.Nahata College of Pharmacy, Mandsaur, India.
Abstract:
Quantification of structure activity relationships was performed on a series of indazole estrogen analogs, for their relative beta estrogenic receptor agonist activity, in order to understand the essential structural requirements for selectivity of indazole estrogen analogs for beta-estrogenic receptor over alpha-estrogenic receptor. The de novo and Hansch approach suggested that the 3(rd) position of indazole nucleus (R(1)) is decisive for the selectivity of molecules towards beta-estrogenic receptor over alpha-estrogenic receptor. The study also depicted that the substitution of polar group at R(1) position might prove helpful in the beta-estrogenic receptor selectivity (ER(beta/alpha )).
