-
Paragraph 0018; 0023; 0029, (2018/03/01)
The invention discloses a synthetic method of decoquinate, and belongs to the technical field of pharmaceutical engineering. The synthetic method takes o-hydroxyphenyl ethyl ether as a raw material to prepare decoquinate via the processes of coupling, reduction, condensation, etherification, cyclization and the like. The process of reduction in the method adopts environment-friendly hydrazine hydrate as a reducer to reduce an azo-compound and introduce an amino group, so that the synthetic method is good in selectivity, and environmentally friendly, and beneficial for reducing environmental pollution problems; BTC is adopted as a cyclization reagent in the process of cyclization, so that the condition is mild, the requirement on equipment is lowered, and the cost is reduced.

A series of novel quinoline carboxylate derivatives with methyl (E)-2-(3-methoxy) acrylate group were designed and synthesized as anticoccidial medicines. The structures were confirmed by 1H NMR, IR and HR-MS spectra. The biological activities were primarily evaluated according to the anticoccidial index method. The results indicated that these compounds (7c, 7d, 7e, 7g) exhibited anticoccidial activities against Eimeria tenella. In particular, the anticoccidial index of 6-decyloxy-7-ethoxy-4-{6-[2-(2-methoxy-1-methoxycarbonyl- vinyl)phenoxy]pyrimidin-4-yloxy}- quinoline-3-carboxylic acid ethyl ester (7e) was 168.7, which indicated that the compound has a good anticoccidial activity.

Page/Page column 84, (2009/09/28)
The present invention concerns novel compounds, their preparation and their uses, therapeutic uses in particular. More specifically it concerns derivative compounds having at least two aromatic cycles, their preparation and their uses, in particular in the area of human or animal health. These compounds have an affinity for the biological receptors of neuropeptide Y, NPY, present in the central and peripheral nervous systems. The compounds of the invention are preferably NPY antagonists, and more particularly antagonists of sub-type NPY Y1, and can therefore be used for the therapeutic or prophylactic treatment of any disorder involving NPY. The present invention also concerns pharmaceutical compositions containing said compounds, their preparation and their uses, as well as treatment methods using said compounds.
