2-(4-Methoxyphenoxy)acetic acid (cas: 1877-75-4) belongs to ethers. Relative to alcohols, ethers are generally less dense, are less soluble in water, and have lower boiling points. They are relatively unreactive, and as a result they are useful as solvents for fats, oils, waxes, perfumes, resins, dyes, gums, and hydrocarbons. Vapours of certain ethers are used as insecticides, miticides, and fumigants for soil. Autoxidation is the spontaneous oxidation of a compound in air. In the presence of oxygen, ethers slowly autoxidize to form hydroperoxides and dialkyl peroxides. If concentrated or heated, these peroxides may explode. To prevent such explosions, ethers should be obtained in small quantities, kept in tightly sealed containers, and used promptly.Recommanded Product: 2-(4-Methoxyphenoxy)acetic acid

And the article was included in Bioorganic & Medicinal Chemistry Letters in 2014.Recommanded Product: 2-(4-Methoxyphenoxy)acetic acid This article mentions the following:

D-Serine is a coagonist of the N-methyl-D-aspartate (NMDA)-type glutamate receptor and its biosynthesis is catalyzed by serine racemase (SR). The overactivation of the NMDA receptor has been implicated in the development of neurodegenerative diseases, strokes, and epileptic seizures, thus, the inhibitors of SR have potential against these pathol. states. Here, we have developed novel inhibitors of SR by in silico screening and in vitro enzyme assay. The newly developed inhibitors have lower IC50 value comparing with that of malonate, one of the standard SR inhibitor. The structural features of novel inhibitors suggest the importance of central amide structure having a phenoxy substituent in their structure for the SR inhibitory activity. The present findings suggest the importance and rational development of new drugs for diseases of NMDAR overactivation. In the experiment, the researchers used many compounds, for example, 2-(4-Methoxyphenoxy)acetic acid (cas: 1877-75-4Recommanded Product: 2-(4-Methoxyphenoxy)acetic acid).

2-(4-Methoxyphenoxy)acetic acid (cas: 1877-75-4) belongs to ethers. Ether is less polar than esters, alcohols or amines because of the oxygen atom that is unable to participate in hydrogen bonding due to the presence of bulky alkyl groups on both sides of the oxygen atom. Ethers are good solvents partly because they are not very reactive. Most ethers can be cleaved, however, by hydrobromic acid (HBr) to give alkyl bromides or by hydroiodic acid (HI) to give alkyl iodides.Electric Literature of C9H10O4

A method to produce (Z)-trifluoromethyl enol esters via the olefination and trifluoromethylation of carboxylic acids with TMSCF3 was reported. This synthetic method used inexpensive and easy-to-handle TMSCF3. It employed a com. available CuCl catalyst to transform a broad range of carboxylic acids into versatile (Z)-trifluoromethyl enol esters with good regio- and stereoselectivity.

The kinetics of oxidation of phenoxyacetic acid and several para- and meta-substituted phenoxyacetic acids by tetrakis(pyridine) cobalt(II) chromate (TPCC) in the presence of HClO4 was studied in aqueous acetic acid medium. The reaction shows unit order dependence each with respect to oxidant and substrate. The order with respect to hydrogen ion concentration is one. The rate of oxidation increases with increase in the percentage of acetic acid and increase in ionic strength has negligible effect on the rate. The addition of Al3+ had a noticeable catalytic effect on the reaction rate. In general, the electron releasing substituent accelerates the rate while electron attracting substituent retards the rate of reaction.

Based on the promising results of benzenesulfonamide spirodienones as antineoplastic agents, a series of novel acyl sulfonamide spirodienones I [R = Me, C6H5, 4-MeC6H4, etc.; R1 = H, Me] were designed and synthesized for antineoplastic evaluation. Of these, compound I [R = 4-MeC6H4, R1 = H] exhibited remarkable in-vitro antiproliferative activity by arresting the cell cycle and inducing apoptosis of MDA-MB-231 cells. Acute toxicity study demonstrated that compound I [R = 4-MeC6H4, R1 = H] at 100 mg/kg dose caused no obvious toxicity to the major organs of mice. Moreover, compound I [R = 4-MeC6H4, R1 = H] suppressed the growth of murine 4T1 tumor in-vivo. Preliminary enzyme assay showed that I [R = 4-MeC6H4, R1 = H] was a potential MMP2 inhibitor for cancer therapy.

Kinetics of oxidation of phenoxyacetic acids by pyridinium hydrobromide perbromide was written by Karunakaran, K.;Elango, K. P.. And the article was included in Journal of Physical Organic Chemistry in 1996.Synthetic Route of C9H10O4 This article mentions the following:

The oxidation of several monosubstituted phenoxyacetic acids by pyridinium hydrobromide perbromide (PHPB) was studied in aqueous acetic acid. The reaction is first order with respect to PHPB. Michaelis-Menten-type kinetics are observed with respect to phenoxyacetic acids. The oxidation of [2,2-2H2]phenoxyacetic acid exhibits a substantial kinetic isotopic effect. The effect of solvent composition indicates that the transition state is more polar than the reactants. The formation constants of the intermediate phenoxyacetic acid-PHPB complexes and the rates of their decomposition were determined at different temperatures The rates of oxidation of para- and meta-substituted phenoxyacetic acids were correlated with Hammett’s substituent constants The 锜?value is -2璺?9 at 35鎺? The rates of oxidation of ortho-substituted compounds are correlated with Charton’s triparametric equation.

This work describes the design, synthesis, and evaluation of low-mol. weight peptidic SARS-CoV 3CL protease inhibitors. The inhibitors were designed based on the potent tripeptidic Z-Val-Leu-Ala(pyrrolidone-3-yl)-2-benzothiazole (I) (Ki = 4.1 nM), in which the P3 valine unit was substituted with a variety of distinct moieties. The resulting series of dipeptide-type inhibitors displayed moderate to good inhibitory activities against 3CLpro.

These low-mol. weight compounds are attractive leads for the further development of potent peptidomimetic inhibitors with pharmaceutical profiles. Docking studies were performed to model the binding interaction of the compound II (R1 = OMe, R2 = H) with the SARS-CoV 3CL protease. The preliminary SAR study of the peptidomimetic compounds with potent inhibitory activities revealed several structural features that boosted the inhibitory activity: (i) a benzothiazole warhead at the S1′ position, (ii) a 绾?lactam unit at the S1-position, (iii) an appropriately hydrophobic leucine moiety at the S2-position, and (iv) a hydrogen bond between the N-arylglycine unit and a backbone hydrogen bond donor at the S3-position.
