Electrocatalytic synthesis of α,α-gem-dihalide ketones from α-mono-halide ketones and unexpected dimer condensation was written by Zhou, Bei;He, Yu-Juan;Tao, Yun-Feng;Liu, Lan-Xiang;Hu, Min;Chang, Zu-Hui;Lei, Hong;Lin, Jun;Lin, Tong;Du, Guan-Ben. And the article was included in Green Chemistry in 2022.COA of Formula: C6H9ClO3 The following contents are mentioned in the article:

A novel, environmentally friendly electrocatalytic process was developed to prepare α,α-gem-dihalide (F, Cl, and Br) ketones from α-mono-halide ketones in an aqueous solution containing alkali halide salts. The gem-dihalides had the same or different halogens on the same carbon, depending on the reactant and inorganic halide salt used. An electron-withdrawing group, such as carbonyl, located at the α-site of mono-halogenated carbon, was essential to the reaction. The electrosyntheses were performed under ambient conditions without inert gas protection and displayed yields of about 80%. This method avoided the classical haloform elimination reaction. However, when the aqueous solution contained NaOH, two α-mono-halide ketone mols. had a special dimer condensation. The reaction mechanisms were explored by conducting GC-MS, EPR, and CV with DFT calculations These revealed that in situ generation of a halogen radical initiated electrocatalytic halogenation, while the dimer condensation involved a hydroxyl radical-mediated C1 fragment elimination. This study involved multiple reactions and reactants, such as Ethyl 4-chloro-3-oxobutanoate (cas: 638-07-3COA of Formula: C6H9ClO3).

Ethyl 4-chloro-3-oxobutanoate (cas: 638-07-3) belongs to organic chlorides. Chlorination modifies the physical properties of hydrocarbons in several ways. These compounds are typically denser than water due to the higher atomic weight of chlorine versus hydrogen. Organochlorine compounds are lipophylic, meaning they are more soluble in fat than in water. This gives them a high tenancy to accumulate in the food chain (biomagnification).COA of Formula: C6H9ClO3

Targeting the protein-protein interaction (PPI) between nuclear factor erythroid 2-related factor 2 (Nrf2) and Kelch-like ECH-associated protein 1 (Keap1) is a potential therapeutic strategy to control diseases involving oxidative stress. Here, six classes of known small-mol. Keap1-Nrf2 PPI inhibitors were dissected into 77 fragments in a fragment-based deconstruction reconstruction (FBDR) study and tested in four orthogonal assays. This gave 17 fragment hits of which six were shown by X-ray crystallog. to bind in the Keap1 Kelch binding pocket. Two hits were merged into pyrazole I with a 220-380-fold stronger affinity (K_i = 16μM) relative to the parent fragments. Systematic optimization resulted in several novel analogs with K_i values of 0.04-0.5μM, binding modes determined by X-ray crystallog., and enhanced microsomal stability. This demonstrates how FBDR can be used to find new fragment hits, elucidate important ligand-protein interactions, and identify new potent inhibitors of the Keap1-Nrf2 PPI.

The asym. reduction of prochiral ketones is a promising process for synthesis of optically active alcs. The aldo-keto reductase (AKR) is an attractive candidate of biocatalyst, due to its high enantioselectivity and environmentally friendly reaction conditions. In this work, nine putative AKR encoding genes from Corallococcus sp. EGB were cloned and expressed in Escherichia coli. Of these produced enzymes (CoAKRs), CoAKR7 exhibited reductive activity to various ketones and ketoesters, especially very high activity toward Et 4-chloro-3-oxobutanoate (COBE) with NADPH as the coenzyme. The CoAKR7 was optimally active at pH 7.0 and 50 °C. The apparent K_m and V_max for COBE was 14.18 U/mg and 0.269 mM, resp. Moreover, CoAKR7 catalyzed an anti-Prelog reduction of COBE to (S)-ethyl-4-chloro-3-hydroxybutanoate (CHBE) with e.e. >99%.

The receptor tyrosine kinase Axl plays important roles in promoting cancer progression, metastasis, and drug resistance and has been identified as a promising target for anticancer therapeutics. We used mol. modeling-assisted structural optimization starting with the low micromolar potency compound I to discover compound II, a highly potent and orally bioavailable Axl inhibitor. Selectivity profiling showed that II could inhibit the well-known oncogenic kinase Met with equal potency to its inhibition of Axl superfamily kinases. Compound II significantly inhibited cellular Axl and Met signaling, suppressed Axl- and Met-driven cell proliferation, and restrained Gas6/Axl-mediated cancer cell migration or invasion. Furthermore, II exhibited significant antitumor efficacy in Axl-driven and Met-driven tumor xenograft models, causing tumor stasis or regression at well-tolerated doses. All these favorable data make II a promising therapeutic candidate for cancer treatment.

An Efficient and Versatile Deep Eutectic Solvent-Mediated Green Method for the Synthesis of Functionalized Coumarins was written by Rather, Ishfaq Ahmad;Ali, Rashid. And the article was included in ACS Omega in 2022.Reference of 638-07-3 The following contents are mentioned in the article:

Herein, we report a green and efficient synthetic route for the construction of diverse functionalized coumarins in good-to-excellent yields (60-98%) via the Pechmann condensation. The optimized synthetic route involves a biodegradable, reusable, and inexpensive deep eutectic solvent (DES) of choline chloride and L-(+)-tartaric acid in a ratio of 1:2 at 110°C. Interestingly, phloroglucinol and Et acetoacetate, upon reaction, furnished the functionalized coumarin (I) in 98% yield within 10 min. On the other front, the same DES at relatively lower reaction temperature (90°C) was found to provide the bis-coumarins in decent yields (81-97%) within 20-45 min. Moreover, this particular method was found to be quite effective for large-scale coumarin synthesis without noteworthy reduction in the yields of the desired products. Noticeably, in this versatile approach, the DES plays a dual role as solvent as well as catalyst, and it was effectively recycled and reused four times with no significant drop-down in the yield of the product. This study involved multiple reactions and reactants, such as Ethyl 4-chloro-3-oxobutanoate (cas: 638-07-3Reference of 638-07-3).

Ethyl 4-chloro-3-oxobutanoate (cas: 638-07-3) belongs to organic chlorides. An organic chloride is an organic compound containing at least one covalently bonded atom of chlorine.

Six coumarin-caged compounds of 1-naphthaleneacetic acid (NAA) comprising different substituents on the coumarin moiety were synthesized and evaluated for their photophys. and chem. properties as light-responsive controlled-release plant root stimulators. The ¹H NMR and HPLC techniques were used to verify the release of NAA from the caged compounds After irradiation at 365 nm, the caged compounds exhibited the fastest release rate at t_1/2 of 6.7 days and the slowest release rate at t_1/2 of 73.7 days. Caged compounds at high concentrations (10^-5 and 10^-6 M) significantly stimulate secondary root germination while free NAA at the same level is toxic and leads to inhibition of secondary root germination. The cytotoxicity of the caged compounds against fibroblasts and vero cells were evaluated, and the results suggested that, at 10^-5-10^-6 M, caged compounds exhibited no significant cytotoxicity to the cells. Thus, the caged compounds of NAA in this study could be of great benefit as efficient agrochems.
