The present invention provides a use of an acylated derivative of an amino acid in preparing animal feed additive. The acylated derivative of the amino acid or a racemate, stereoisomer, a geometric isomer, a tautomer, a solvate, and a feed-acceptable salt thereof of the present invention has a structure represented by formula (I).
The acylated derivative of the amino acid or the racemate, the stereoisomer, the geometric isomer, the tautomer, the solvate, and the feed-acceptable salt thereof provided in the present invention may be used as an animal feed additive, and has a good effect of improving production performance of animals.
The invention relates to compounds of general formula (I) and pharmaceutically acceptable salts thereof: (I) wherein Ri is selected from an SCN— group or is an RCONH— group; in particular, where Ri=RCONH, R is selected from an aromatic benzene ring substituted with an SCN— group in the ortho, meta or para position, according to the following formula: SCN— or R is a C1-C4 alkyl chain, substituted with an SCN— group; n can be equal to 0 or else 1. The invention also relates to the use of such compounds for the treatment of osteoporosis and in general of bone pathologies characterized by a progressive loss of bone mass, for example rheumatoid arthritis, hyperparathyroidism or bone tumor metastases.
本发明涉及通式(I)的化合物及其药学上可接受的盐:(I) 其中 Ri 选自 SCN-基团或 RCONH-基团;特别是当 Ri=RCONH 时,R 选自在正位、偏位或对位被 SCN-基团取代的芳香苯环,如下式:SCN-或 R 是被 SCN-基团取代的 C1-C4 烷基链;n 可以等于 0,也可以是 1。本发明还涉及使用这类化合物治疗骨质疏松症,以及一般以骨量逐渐丧失为特征的骨病,例如类风湿性关节炎、甲状旁腺功能亢进症或骨肿瘤转移。
