Reference of 105-34-0, Methyl cyanoacetate is an alkyl cyanoacetate ester.
Methyl cyanoacetate is the intermediate product in pharmaceutical organic synthesis as well as in the synthesis of some biologically active compounds used in agriculture. It undergoes calcite or fluorite catalyzed Knövenagel condensation with aromatic aldehydes, giving the corresponding arylidenemalononitriles and (E)-α -cyanocinnamic esters.
Methyl Cyanoacetate is often used as a nucleophile in the electrochemical oxidation of catechols. Methyl Cyanoacetate is also a reagent in the synthesis of Methyl 2-Amino-4-trifluoromethylthiophene-3-carboxylate (M287290); a compound used in the synthesis of DPP-IV inhibitors for treating type 2 diabetes., 105-34-0.

Nitrile groups in organic compounds can undergo a variety of reactions depending on the reactants or conditions. 105-34-0, formula is C4H5NO2, Name is Methyl 2-cyanoacetate. A nitrile group can be hydrolyzed, reduced, or ejected from a molecule as a cyanide ion. Reference of 105-34-0.

Wang, Ziqian;Zhang, Xiaodong;Zhang, Hong;Tang, Yao;Pan, Hao;Wang, Hang;Ji, Tong;Guo, Yafei;Gao, Qishuang;Song, Ting;Zhang, Zhichao research published 《 Discovery of a fluorogenic probe for in situ pyruvate kinase M2 isoform (PKM2) labeling through chemoselective SNAr with a binding site lysine residue》, the research content is summarized as follows. The key challenge of developing reaction-based turn-on probes is to establish latent electrophilic fluorophores exhibiting high reactivity only upon binding to a specific protein(s). Herein, we identified such a fluorophore, 6-arylthioether-substituted 3-cyano-1-oxo-1H-phenalene-2-carboxylate, which chemoselectively labels binding site Cys or Lys residues. Based on this fluorophore, we developed the first reaction-based turn-on pyruvate kinase M2 isoform (PKM2) fluorescent probe AT-OPC1, which selectively labels PKM2 with the binding site Lys305. The latent electrophilic reactivity of the fluorophore endows the probe with precise detection of the expression of PKM2 in situ by means of both in-gel fluorescence imaging at the proteome level and real-time no-wash cell imaging approaches, which has the potential to be applied in cancer diagnoses.
