L. Turker et al., QUANTITATIVE STRUCTURE-ACTIVITY RELATIONSHIP STUDY OF SOME 7-SUBSTITUTED THEOPHYLLINES, Arzneimittel-Forschung, 48(1), 1998, pp. 39-42
Some novel 7-substituted theophylline derivatives have been investigat
ed for quantitative structure-activity relationship (QSAR). For this p
urpose, their bronchodilatory activities (in vitro), which were examin
ed by the inhibition of acetylcholine induced contraction in tracheae
isolated from guinea pigs, have been correlated with various quantum c
hemical and physicochemical parameters.
