Synthesis and biological activities of hydroxyl-protected fluorine-containing 4,4-dihydroxylmethyl-2-aryl-iminothiazolidines
摘要:
Eight novel compounds were synthesized by a facile and mild method with high yields, and the structures of all the compounds were characterized by H-1 NMR IR mass and high resolution mass spectroscopy. Their inhibitory activity against insect-flight and trehalase in vitro were screened. Some target compounds have moderate inhibitory activity against trehalase, and show inhibition action to insect-flight. (C) 2004 Elsevier B.V. All rights reserved.
Synthesis and Quantitative Structure−Activity Relationships of Fluorine-Containing 4,4-Dihydroxylmethyl-2-aryliminooxazo(thiazo)lidines as Trehalase Inhibitors
摘要:
Five fluorine-containing 4,4-dihydroxylmethyl-2-aryliminooxazolidines and five 4,4-dihydroxylmethyl-2-aryliminothiazolidines were synthesized and evaluated for their inhibitory activity against trehalase in vitro. All these compounds were very readily synthesized compared with the natural trehalase inhibitors. They had moderate inhibitory activity toward trehalase, and showed larvicidal activity and inhibition action to insect flight. The steric parameters and semiempirical quantum parameters of these compounds were acquired by using the molecular modeling method and the PM3-SCF-MO method, respectively. A quantitative structure-activity relationship between half-inhibitory concentrations toward trehalase and the above parameters was established.
