A set of 21 highly flexible competitive inhibitors of thymidylate synthase
(TS; EC 2.1.1.45) covering a wide activity range (IC50 = 6 nM-100 mu M) has
been investigated by three-dimensional quantitative structure-activity rel
ationship (3D-QSAR). CATALYST(TM) was used to generate three-dimensional hy
potheses to study the common interaction features among a set of thymidylat
e synthase inhibitor. The verification of the hypothesis was achieved by us
ing the molecules outside the training set. (C) 2000 Elsevier Science Ltd.
