| 摘要 |
<p>This invention relates to oxiranecarboxylic acid ester derivatives. There are provided 3-substituted-2-(aminocarbonyl)-oxiranecarboxylic acid esters of formula (I) wherein R is phenyl substituted by one or two groups independently selected from nitro and alkoxy or is benzoyl, R3 is alkyl, alkenyl, alkynyl or cycloalkyl, R1 and R2 are each independently hydrogen, alkyl, alkenyl, alkynyl or cycloalkyl or R1 and R2 together represent an alkylene chain containing four or five carbon atoms; processes for their preparation; lipogenesis-inhibiting compositions containing them and the preparation of such compositions. Oxirane carboxylic acid ester derivatives of formula I have exhibited lipogenesis inhibiting activity, and thus find use in animal husbandry to provide a leaner carcass after slaughter.</p> |
