标题:主动脉瓣狭窄患者主动脉瓣置换对n端利钠前肽的影响
摘要:背景技术已经证实,利钠肽的血浆浓度增加与心内压升高和左心室(lv)肥大有关.主动脉瓣狭窄患者进行主动脉瓣置换(avr)后,左流出道梗阻得到缓解,血流动力学显着改善.随后是lv肥大的逐渐消退.假设avr后,预计lv充盈压会迅速降低,而lv肥大的消退将在更长的时间内发生.在此基础上,我们假设,在术后早期,血浆n端原发性钠尿肽(nt-Proanp)的血浆水平会降低,而n端原发性脑钠尿素肽(nt-Probnp)则通过其对lv肥大的密切反映而降低.,将持续更长的时间.方法两组接受avr的主动脉瓣狭窄患者分别随访4个月和12个月.在avr之前和之后测量血浆nt-Proanp和nt-Probnp的浓度,并与术前的发现和主动脉瓣面积指数的变化有关.结果在进行avr之前,患者的血浆nt-Proanp和nt-Probnp明显升高.Avr后,Nt-Proanp在第4和12个月下降,但与对照组相比仍然升高.N-

标 题 :Green chemistry synthesis of the malaria drug amodiaquine and analogs thereof
发明人：FORTUNAK JOSEPH MARIAN; KULKARNI AMOL ANANT; KING CHRISTOPHER
权利人:UNIV HOWARD
摘要:Methods are provided for a green chemistry one-pot synthesis of amodiaquine and amodiaquine analogs. The methods have a lower environmental impact, lower investment cost, reduced amounts of byproducts and impurities, and a shorter synthesis time, compared to current conventional synthesis methods. The methods reduce the total number of steps in the synthesis from four to five down to two, thereby simplifying production; and allow a reduced number of solvents and reagents to be used in production, thereby reducing the waste generated in the synthesis. The methods can reduce the waste to about 3-5 kilograms of waste generated per kilogram of product produced; and surprisingly improve the overall yield from 60-65% to greater than 90% as compared to the current conventional synthesis methods for amodiaquine and its analogs.

摘要:Disclosed embodiments relate to improved methods for the synthesis of activated fumarate intermediates and their use in chemical synthesis. Disclosed embodiments describe the synthesis of activated fumarate esters including those derived from activating groups including: 4-nitrophenyl, diphenylphosphoryl azide, pivaloyl chloride, chlorosulfonyl isocyanate, p-nitrophenol, MEF, trifluoroacetyl and chlorine, for example, ethyl fumaroyl chloride and the subsequent use of the activated ester in situ. Further embodiments describe the improved synthesis of substituted aminoalkyl-diketopiperazines from unisolated and unpurified intermediates allowing for improved yields and reactor throughput.

摘要:The present invention refers to the synthesis of 3-{[(2R)-1-methylpyrrolidin-2-yl]methyl}-5-[2-(phenylsulfonyl)ethyl]-1H-indole, a drug known by the name Eletriptan, or of its salts. In particular, the present invention regards a process for the synthesis of Eletriptan or of its salt, comprising the following steps: a) Salifying the intermediate of Formula (6), using a dicarboxylic acid to obtain a derived salt; b) Optionally, purifying said raw salt obtained according to step a) by solvent crystallization to obtain a purified salt of the intermediate of Formula (6); c) Converting said salt of the intermediate of formula (6) according to step a) or said purified salt according to step b) into an intermediate of formula (10); d) Converting the intermediate of Formula (10) into Eletriptan or its salt.
