The present invention provides a novel benzamide derivative represented by formula 1 and an isomer, a pharmaceutically acceptable salt or hydrate thereof, and a composition for activating a 5-HT4 receptor comprising the same, as an active ingredient. Benzamide derivatives of the present invention has superior affinity for 5-HT4 receptors, capability to reduce the gastric evacuation time, capability to alleviate ventricular tachycardia, ventricular fibrillation, torsades de pointes and QT prolongation, and low toxicity. Therefore, benzamide derivatives of the present invention are therapeutically effective for digestive system diseases.
An efficient method for targeting a variety of symmetrical and asymmetrical α-substituted dithiomalonates (DTMs) is described, utilizing 1H-imidazole-1-carbothioates as reactive acylating agents and MgBr2⋅OEt2/DBU or LiHMDS for soft or hard enolization conditions of thioesters, respectively. The utility of this methodology was demonstrated through the synthesis of the pyridopyrimidine mesoionic insecticides:

[Problem] The object of the present invention is to provide a method for efficiently manufacturing a polypeptide fragment suitable for the NCL method. [Solution] The present invention provides a manufacturing method comprising a step of reacting a polypeptide consisting of a first polypeptide fragment having cysteine at the N-terminal and a second polypeptide fragment linked via an intervening sequence -Cys-W-(His)n-Z-Met- with CNBr to obtain a first polypeptide fragment having cysteine at the N-terminal and a third polypeptide fragment, and a step of sequentially reacting the third polypeptide fragment with a compound represented by the following formula (I) and a compound represented by the following formula (II) to obtain a second polypeptide fragment having the C-terminal modified.
[问题]本发明的目的是提供一种高效制造适用于 NCL 法的多肽片段的方法。[解决方案] 本发明提供了一种制造方法,包括以下步骤:将由 N 端具有半胱氨酸的第一 多肽片段和通过中间序列-Cys-W-(His)n-Z-Met-连接的第二多肽片段组成的多肽与 CNBr 反应,得到 N 端具有半胱氨酸的第一多肽片段和第三多肽片段、以及将第三多肽片段依次与下式(I)代表的化合物和下式(II)代表的化合物反应,得到 C-末端被修饰的第二多肽片段的步骤。
