Ethyl 3-oxo-3-(thiophen-2-yl)propanoate (cas: 13669-10-8) belongs to esters. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.COA of Formula: C9H10O3S

Simplification of the tetracyclic SIRT1-selective inhibitor MC2141: Coumarin- and pyrimidine-based SIRT1/2 inhibitors with different selectivity profile was written by Rotili, Dante;Carafa, Vincenzo;Tarantino, Domenico;Botta, Giorgia;Nebbioso, Angela;Altucci, Lucia;Mai, Antonello. And the article was included in Bioorganic & Medicinal Chemistry in 2011.COA of Formula: C9H10O3S This article mentions the following:

In this report we describe the synthesis and biol. characterization of two series of sirtuins’ inhibitors (SIRTi), designed as simplification products of the previously reported SIRT1-selective inhibitor MC2141 (4). In the first series (5a-t) we report a number of 2-substituted-1,2-dihydrobenzo[f]chromen-3-ones with a marked selectivity for the inhibition of SIRT2 over SIRT1. Some of such derivatives showed also high pro-apoptotic (5i and 5l) and/or cytodifferentiating (5d, 5i, and 5o) properties in a human leukemia cell line (U937). The second group of SIRTi (6a-q) is characterized by some analogs of cambinol (3), a well known SIRTi active against the Burkitt lymphoma. Such compounds, differently from the unselective prototype, are endowed with a selective inhibition of SIRT1 over SIRT2, and, in some cases (6j, 6k, and 6q), are more efficient than 3 to induce apoptosis in U937 cells. In the experiment, the researchers used many compounds, for example, Ethyl 3-oxo-3-(thiophen-2-yl)propanoate (cas: 13669-10-8COA of Formula: C9H10O3S).
