摘要: A series of novel 2-oxocycloalkylsulfonamides ( 4) were synthesized and their structures confirmed by IR, H-1 NMR, and elemental analysis. The bioassay showed that they have fair to excellent fungicidal activities against Botrytis cinerea Pers and Sclerotinia sclerotiorum. Among them, compounds 4A(10), 4A(11), 4A(12), 4B(2), and 4B(3), the EC50 values of which were 2.12, 3.66, 3.96, 2.38, and 2.43 mu g/mL, respectively, displayed excellent fungicidal activity against B. cinerea Pers, and are comparable with commercial fungicide procymidone ( the EC50 value is 2.45 mu g/mL). 3D QSAR against B. cinerea Pers was studied, a statistically significant and chemically meaningful CoMFA model was developed and some compounds which have a high predicted activity were forecasted. In addition, the bioassay also showed that the compounds have good inhibitory activities against human tumor cells HL-60, BGC-823, Bel-7402 and KB. It is interesting to point out that the antitumor activities of compounds 4 are in accordance with their fungicidal activity to a great extent: compounds having relatively best antitumor activities ( 4A10, 4A11, 4A12, and 4B3) also displayed excellent fungicidal activity.
