Methylα-d-glucopyranoside as a model acceptor was acylated by several phenolic and non-phenolic vinyl esters using immobilised Lipolase. Donor specificity and regioselectivity of reaction were investigated. Conversion and rate of acylation by structurally varied donors indicates that the synthetic reactivity of Lipolase corresponds to the hydrolytic activity of feruloyl esterase type A. Lipolase exhibited

A series of activated and nonactivated esters of 2-furoic and 2-furylacrylicacids were synthesized and examined for antineoplastic activity in the Ehrlich ascites carcinoma screen at 20 mg/kg/d. 2-Furoicacid and 2-furylacrylicacid demonstrated potent activity, as did the methyl and cyanomethyl esters of each series. The vinyl ester of 2-furoicacid possessed antineoplastic activity. However, the
合成了一系列2-糠酸和2-糠基丙烯酸的活化和非活化酯,并在Ehrlich腹水癌筛查中以20 mg / kg / d的剂量检测其抗肿瘤活性。2-糠酸和2-糠基丙烯酸显示出有效的活性,每个系列的甲基和氰基甲基酯也是如此。2-糠酸的乙烯基酯具有抗肿瘤活性。但是,每个系列的乙基和D,L-四氢吡喃基酯在肿瘤筛查中均无活性。
