Starting with Coumarin-6 dye, two novel D-π-A organic dyes C6X and C6N have been designed by attaching carboxylic acid and cyanoacrylic acid groups as anchoring groups to Coumarn-6 dye, respectively, to understand their potential use in dye-sensitized solar cells (DSSCs). The electronic ...
摘要: The reaction of carboxylic acids with 1-cyanimidazole, 1-cyanobenzimidazole, and 1-cyano-1,2,4-triazole leads to the formation of 1-acylazoles used in situ in synthesis of anilides of the corresponding carboxylic acids.年份: 1996 ...
Pharmaceuticals: 3-Cyanocinnamic acid is used in the pharmaceutical industry for various purposes. Its mechanism of action in this field may involve its ability to act as an intermediate in the synthesis of pharmaceutical compounds. Chemical research: This compound is also utilized in chemical resea...
The structure and mechanism of stem bromelain. Evaluation of the homogeneity of purified stem bromelain, determination of the molecular weight and kinetic ... 1. Purified stem bromelain (EC 3.4.22.4) was eluted from Sephadex G-100 as a single peak. The specific activity across the elution peak...
Mechanism of action of nonsteroidal anti-inflammatory drugs. Salicylic acid and salicylates, obtained from natural sources, have long been used as medicaments. Salicylic acid was chemically synthesized in 1860 and wa... Bruera,Eduardo - 《American Journal of Medicine》...
Fig. 2: Cyanosulfurylides as protecting groups for carboxylic acids. a Cyanosulfurylide 1 undergoes a rapid reaction with electrophilic halogen species, leading to the release of the unprotected carboxylic acid 2. A postulated mechanism proceeds via electrophilic halogenation followed by hydration and ...
In addition, the strong inhibition of the enzyme by Pefabloc® and phenylmethylsulfonyl fluoride indicated that the catalytic mechanism of CphE is related to that of serine type proteases. Quantitative analysis on the release of β-Asp-Arg dipeptides from C-terminal labeled CGP gave evidence for...
A substitution reaction of 4-nitrofuroxans to prepare 4-cyanofuroxans is described. This substitution reaction was complicated by the reverse reaction and a judicious choice of cyanide source was important to enable this direct synthesis process. The optimized reaction conditions showed an excellent ap...
Accordingly, the higher value of 15.6 Hz for the bioconversion product gave reason to conclude that the trans isomer of the monoamide (trans-3-cyanoacrylamide) was formed and is consistent with the conventional mechanism of nitrilase-catalyzed reactions in which small quantities of the amide ...
In a first step the known 2-nitro-benzaldehydes (XIII) are alkenated to the intermediates of formula (XXV) under art known conditions, for example, using the Wittig Reaction with the appropriate phosphonium salt of formula (XXIV). Following esterification of the free carboxylic acid under stand...
