A COMPARATIVE MOLECULAR-FIELD ANALYSIS MODEL FOR 6-ARYLPYRROLO[2,1-D][1,5]BENZOTHIAZEPINES BINDING SELECTIVELY TO THE MITOCHONDRIAL BENZODIAZEPINE RECEPTOR
G. Greco et al., A COMPARATIVE MOLECULAR-FIELD ANALYSIS MODEL FOR 6-ARYLPYRROLO[2,1-D][1,5]BENZOTHIAZEPINES BINDING SELECTIVELY TO THE MITOCHONDRIAL BENZODIAZEPINE RECEPTOR, Journal of medicinal chemistry, 37(24), 1994, pp. 4100-4108
A series of 42 6-arylpyrrolo[2,1-d][1,5]benzothiazepines which we have
recently described as selective ligands of the mitochondrial benzodia
zepine receptor (MBR) (Fiorini I.; et al. J. Med. Chem. 1994, 37, 1427
-1438), have been investigated using the comparative molecular field a
nalysis (CoMFA) approach. The resulting 3D-QSAR model rationalizes the
steric and electronic factors which modulate affinity to the MBR with
a cross-validation standard error of 0.648 pIC(50) unit. A set of sev
en novel pyrrolobenzothiazepine congeners has successively been synthe
sized and tested. The CoMFA model forecasts the binding affinity value
s of these new compounds with a prediction standard error of 0.536.
