Tn. Ojha et al., QUANTITATIVE STRUCTURE-ACTIVITY RELATIONSHIP STUDY OF 8-STYRYLXANTHINES AS A2-SELECTIVE ADENOSINE ANTAGONISTS, Indian journal of chemistry. Sect. B: organic chemistry, including medical chemistry, 34(5), 1995, pp. 452-455
Through quantitative structure-activity relationship (QSAR) analysis o
f some 8-styrylxanthines as A2-selective adenosine antagonists, it is
derived that for better potency ligands, electron withdrawing groups a
t ortho- and para-positions while bulky groups at both the meta-positi
ons of the phenyl ring in styryl substituent are advantageous.
