Use of diaminoguanidine derivative and feed composition thereof in preparation of veterinary drug
View Patent ↗Disclosed is a use of a diaminoguanidine derivative and a feed composition thereof in the preparation of a veterinary drug. Particularly, disclosed is a use of a diaminoguanidine derivative having a structure of formula (I), or a stereoisomer, geometric isomer, tautomer, solvate, pharmaceutically acceptable salt thereof, or a prodrug thereof, in the preparation of an animal drug for preventing, managing, treating, or alleviating a disease resulting from bacterial infection, wherein R is NO 2 , or a group represented by formula (II) or formula (III); R 1 is a linear or branched C 1 -C 20 alkyl group; A is O, NH or S; R 2 is a linear or branched C 3 -C 14 alkyl, C 5 -C 6 cycloalkyl, C 5 -C 6 aryl or CH 2 (C 5 -C 6 aryl) group. The diaminoguanidine derivative is a non-toxic and safe compound for animals, and is markedly effective in the treatment of infectious diseases in the reproductive system, skin, etc., of farmed animals.
1 . A process for managing, treating or alleviating a disease caused by bacterial infection in an animal by administering to the animal a therapeutically effective amount of a diaminoguanidine derivative of Formula (I), or a stereoisomer, geometric isomer, tautomer, solvate, pharmaceutically acceptable salt, or prodrug thereof:
wherein,
R is according to Formula (II) or (III):
wherein R 1 is a linear or branched C 1 -C 20 alkyl group; A is O, NH or S; and R 2 is a linear or branched C 3 -C 14 alkyl group, C 5 -C 6 cycloalkyl, C 6 aryl, or —CH 2 (C 6 aryl); and wherein the pharmaceutically acceptable salt is a D,L-lactic acid salt, methanesulfonic acid salt, 2-hydroxyethyl sulfonic acid salt, citric acid salt, tartaric acid salt, benzoic acid salt, succinic acid salt, fumaric acid salt, maleic acid salt, acetic acid salt, sulfuric acid salt, phosphoric acid salt, or oxalic acid salt, and wherein the bacterial infection is caused by Staphylococcus aureus , and wherein the disease is mastitis, a skin infection, a gastrointestinal infection, a respiratory infection, or a genitourinary system disease.
2 . The process of claim 1 , wherein R is according to Formula (II), and R 1 is a linear C 1 -C 20 alkyl group.
3 . The process of claim 2 , wherein R 1 is a linear C 1 -C 12 alkyl group.
4 . The process of claim 3 , wherein R 1 is methyl.
5 . The process of claim 1 , wherein R is according to Formula (III), and A is O.
6 . The process of claim 1 , wherein R is according to Formula (III), and A is NH.
7 . The process of claim 1 , wherein R is according to Formula (III), and R 2 is a linear C 3 -C 14 alkyl group.
8 . The process of claim 1 , wherein R is according to Formula (III), and R 2 is a branched C 3 -C 14 alkyl group.
9 . The process of claim 8 , wherein R 2 is a branched C 3 alkyl group, or a branched C 4 alkyl group; and A is O.
10 . The process of claim 1 , wherein the disease is endometritis, mastitis, and/or skin infection.
11 . The process of claim 1 , wherein the diaminoguanidine derivative is a D,L-lactic acid salt, methanesulfonic acid salt, 2-hydroxyethyl sulfonic acid salt, citric acid salt, tartaric acid salt, benzoic acid salt, succinic acid salt, fumaric acid salt, maleic acid salt, acetic acid salt, sulfuric acid salt, phosphoric acid salt, or oxalic acid salt.
