Tp. Blackburn et al., STEREOCHEMICAL DIFFERENTIATION OF ANTICONVULSANT AND ANTIHYPERTENSIVEEFFECTS IN 4-(FLUOROBENZOYLAMINO)BENZOPYRANS, Bioorganic & medicinal chemistry letters, 5(11), 1995, pp. 1163-1166
Replacement of the 2-pyrrolidinone group of cromakalim 1 by the fluoro
benzoylamino group has introduced anticonvulsant activity. It is parti
cularly noteworthy that this activity is found predominantly in the 3R
,4S enantiomeric series. In contrast, antihypertensive activity is res
tricted to the 3S,4R enantiomeric series.
