Diethyl 2-(prop-2-yn-1-yl)malonate (cas: 17920-23-9) belongs to esters. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.Formula: C10H14O4

A Pan Photoaffinity Probe for Detecting Active Forms of Matrix Metalloproteinases was written by Nury, Catherine;Czarny, Bertrand;Cassar-Lajeunesse, Evelyne;Georgiadis, Dimitris;Bregant, Sarah;Dive, Vincent. And the article was included in ChemBioChem in 2013.Formula: C10H14O4 This article mentions the following:

A photoaffinity probe based on the scaffold of a potent broad-spectrum phosphinic peptide inhibitor of matrix metalloproteinases (MMPs) has been developed. A photolabile diazirine group for covalent modification of MMP active forms was incorporated at the P1‘ position, and a tritium radioactive label for the sensitive detection of MMP covalent adducts by radioimaging was attached. The probe was characterized on seven catalytic domains of human MMPs (MMP-2, -3, -8, -9, -12, -13 and -14) and was found to display nanomolar affinities toward this set of MMPs, covalently modifying them with crosslinking yields varying from 12 to 58 %, thus leading to highly sensitive detection of these MMPs. In a complex proteome complemented with four recombinant MMPs (MMP-2, -9, -12 and -13), this probe enabled their simultaneous detection with a threshold of few femtomoles and low background labeling. Those properties should make this new pan-activity-based MMP probe a valuable tool for the detection of MMP active forms from biol. fluids or tissue extracts In the experiment, the researchers used many compounds, for example, Diethyl 2-(prop-2-yn-1-yl)malonate (cas: 17920-23-9Formula: C10H14O4).
