Said quinoline compound is substantially pure of any impurities. The present invention further provides the use of the above-mentioned polymorph of 7-chloro-4-(piperazin-1-yl)-quinoline in the synthesis of piperaquine or one of its pharmaceutically acceptable salts.
专利号:US-2012100555-A1 优先权日:2009-06-29 标题 :Synthesis And Use Of Fluorophore-Tagged Antimalarials 发明人:LEAR MARTIN JAMES; TAN KEVIN SHYONG WEI 权利人:LEAR MARTIN JAMES; TAN KEVIN SHYONG WEI 摘要:This invention includes a fluorophore-tagged antimalarial represented by the following structural formula (1) or a salt thereof. This invention relates to the synthesis of fluorophore-tagged antimalarials and describes the synthesis of a fluorophore-tagged antimalarial. These fluorophore-tagged antimalarials can be used to image live cells to determine the location of the antimalarial in the cell, identify drug resistance and growth related pathways in Plasmodium isolates, identify new drug targets and chemo-sensitizers to reverse drug resistance.

专利号:US-9802952-B2 优先权日:2013-07-15 标 题:Method and apparatus for the synthesis of dihydroartemisinin and artemisinin derivatives 发明人:KOPETZKI DANIEL; MCQUADE DAVID TYLER; SEEBERGER PETER H; GILMORE KERRY 权利人:MAX-PLANCK-GESELLSCHAFT ZUR FÖRDERUNG DER WSS E V; MAX-PLANK-GESELLSCHAFT ZUR FÖRDERUNG DER WSS E V 摘要:The present invention is directed to a method for continuous production of dihydroartemisinin and also artemisinin derivatives derived from dihydroartemisinin by using artemisinin or dihydroartemisinic acid (DHAA) as starting material as well as to a continuous flow reactor for producing dihydroartemisinin as well as the artemisinin derivatives. It was found that the reduction of artemisinin to dihydroartemisinin in a continuous process requires a special kind of reactor and a special combination of reagents comprising a hydride reducing agent, at least one activator such as an inorganic activator, at least one solid base, at least one aprotic solvent and at least one C 1 -C 5 alcohol.
专利号:WO-2023187827-A1 优先权日:2022-03-30 标题:A pharmaceutical composition comprising an inhibitor of glutamine synthetase enzyme to combat artemisinin resistance in malaria 发明人:ARUN NAGARAJ VISWANATHAN; PADMANABAN GOVINDARAJAN; GHOSH SOURAV; KUNDU RAJIB; CHANDANA MANJUNATHA; ANAND ADITYA 权利人:INST OF LIFE SCIENCES 摘要:The present disclosure relates to a pharmaceutical composition to combat artemisinin resistance in malaria with the identification of Plasmodium falciparum (Pf) glutamine synthetase (GS) as a drug target. Pf Gs is important for maintaining asparagine levels in the parasite and promote protein synthesis. Since ART-resistant parasites undergo fitness loss in amino acid/nutrient- limiting conditions and GS levels are upregulated during ART exposure, targeting Pf GS and asparagine requirement can be harnessed to prevent ART resistance. The present disclosure also provides a method of suppressing the growth of Plasmodium falciparum and a method of treating malaria using GS inhibitors.
