Jj. Howbert et al., DIPHENYLPYRAZOLIDINONE AND BENZODIAZEPINE CHOLECYSTOKININ ANTAGONISTS- A CASE OF CONVERGENT EVOLUTION IN MEDICINAL CHEMISTRY, Bioorganic & medicinal chemistry letters, 3(5), 1993, pp. 875-880
Two recently described classes of nonpeptide cholecystokinin receptor
antagonists contain diphenylpyrazolidinone and benzodiazepine substruc
tures, respectively. Although the origins and development of these ser
ies were completely independent, the low energy conformations predicte
d by modeling showed remarkable three-dimensional homology between the
structures.
