Strategies to inhibit kinases by targeting the substrate binding site offer many advantages, including naturally evolved selectivity filters, but normally suffer from poor potency. In this work we propose a strategy to design and prepare covalent substrate-competitive kinase inhibitors as a method to improve potency. We have chosen AKT as the model kinase for this work. Using the AKT-GSK3β cocrystal structure and a reactive cysteine near the substrate binding site, we have identified phenylalanine (Phe) as an appropriate scaffold for the covalent inactivator portion of these inhibitors. By synthesizing compounds that incorporate cysteine-reactive electrophiles into phenylalanine and testing these compounds as AKT inhibitors, we have identified Boc-Phe-vinyl ketone as a submicromolar inactivator of AKT. We also show that Boc-Phe-vinyl ketone (1) potently inhibits AKT1 and inhibits cell growth in HCT116 and H460 cells nearly as well as AKT inhibitors GSK690693 and MK-2206, (2) is selective for kinases that possess an activation loop cysteine such as AKT, (3) requires the vinyl ketone for inactivation, (4) has inactivation that is time-dependent, and (5) alkylates Cys310 of AKT as shown by mass spectrometry. Identification of Boc-Phe-vinyl ketone as a covalent inactivator of AKT will allow the development of peptide and small-mol. substrate-competitive covalent kinase inhibitors that incorporate addnl. substrate binding elements to increase selectivity and potency. This proof-of-principle study also provides a basis to apply this strategy to other kinases of the AGC and CAMK families. In the experiment, the researchers used many compounds, for example, (S)-tert-Butyl (1-(methoxy(methyl)amino)-1-oxo-3-phenylpropan-2-yl)carbamate (cas: 87694-53-9Product Details of 87694-53-9).

(S)-tert-Butyl (1-(methoxy(methyl)amino)-1-oxo-3-phenylpropan-2-yl)carbamate (cas: 87694-53-9) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits. 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.Product Details of 87694-53-9

Transesterification of malonic esters was written by Bondar, L. S.;Rodionov, P. P.;Okunev, R. A.. And the article was included in Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya in 1968.Recommanded Product: malonic acid dibutyl ester This article mentions the following:

Transesterification of malonic esters with various types of alcs. in the presence of alk. and acidic catalysts has been studied. Transesterification of esters catalyzed by alkali proceeds according to an SN2 mechanism and, when catalyzed by acids, proceeds according to a polycentric mechanism. In the former case transesterification of malonic ester (I) is facilitated by enolization of I and in the later case, by the formation of a cyclic intermediate. The corresponding alc. and the catalysts are heated to solution and then a lower ester of malonic acid (dimethyl, diethyl, or dipropyl) is added and the mixture boiled. The alc. formed in the reaction is continuously distilled The reaction is considered complete as soon as the alc. added in the beginning begins to distill. Eleven esters of malonic acid CH2(CO2R)2 (R = n-Pr, n-Bu, sec-Bu, n-C5H11), n-C6H13, cyclohexyl, n-C7H15, PhCH2, n-C9H19, or n-C10H21) were obtained in good yields (69.9 to 96.6%), their physicochem. constants agreed well with those reported in the literature. Transesterification proceeds easily if the difference in the b.ps. of the alc. taken and the alc. formed in the reaction is large. In the experiment, the researchers used many compounds, for example, malonic acid dibutyl ester (cas: 1190-39-2Recommanded Product: malonic acid dibutyl ester).

malonic acid dibutyl ester (cas: 1190-39-2) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits, including apples, durians, pears, bananas, pineapples, and strawberries. Esterification is the general name for a chemical reaction in which two reactants (typically an alcohol and an acid) form an ester as the reaction product. Esters are common in organic chemistry and biological materials.Recommanded Product: malonic acid dibutyl ester

Organic Chemical Contaminants in Water System Infrastructure Following Wildfire was written by Draper, William M.;Li, Na;Solomon, Gina M.;Heaney, Yvonne C.;Crenshaw, Reese B.;Hinrichs, Richard L.;Chandrasena, R. Esala P.. And the article was included in ACS ES&T Water in 2022.Computed Properties of C73H108O12 This article mentions the following:

Wildfires have destroyed multiple residential communities in California in recent years. After fires in 2017 and 2018, high concentrations of benzene and other volatile organic compounds (VOCs) were found in public drinking water systems in fire-affected areas. The sources of the contamination and appropriate remediation have been urgent matter of investigation. This study characterizes target and nontarget VOCs and semivolatile organic compounds in water from a highly contaminated service line after the 2018 Camp Fire (Paradise, CA). Ninety-five organic compounds were identified or tentatively identified in the service line. Laboratory combustion experiments with drinking water pipes made of polyvinyl chloride (PVC), cross-linked polyethylene, and high-d. polyethylene and a review of the literature were used to evaluate potential sources of the detected chems. Among the service line contaminants were 32 compounds associated with PVC pyrolysis and 28 organic compounds also associated with the pyrolysis of polyethylene. The service line sample also contained 55 compounds associated with uncontrolled burning of biomass and waste materials. The findings support hypotheses that wildfires can contaminate drinking water systems both by thermal damage to plastic pipes and intrusion of smoke. Residual chlorine disinfectants in the water system modify the contaminant distribution observed In the experiment, the researchers used many compounds, for example, 2,2-Bis(((3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoyl)oxy)methyl)propane-1,3-diyl bis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoate) (cas: 6683-19-8Computed Properties of C73H108O12).

Mechanical and Processing Enhancement of a Recycled HDPE/PPR-Based Double-Wall Corrugated Pipe via a POE-g-MAH/CaCO₃/HDPE Polymer Composite was written by Wang, Yutong;Lu, Lichang;Hao, Yu;Wu, Yujie;Li, Yuanzhe. And the article was included in ACS Omega in 2021.Electric Literature of C73H108O12 This article mentions the following:

With the people’s awareness of the “3Rs” in recent years, using recycled high-d. polyethylene (HDPE) and random copolymer polypropylene (PPR) as the base materials for piping fabrication has become a mainstream in scholastic path and industrial engineering. In this study, the modified maleic anhydride-grafted polyethylene (POE-g-MAH) compatibilizer was fabricated to increase the interfacial adhesion and dispersion. With the surface modification of calcium carbonate, a POE-g-MAH/CaCO₃/HDPE polymer composite has been prepared Such modified polymer composites can further reinforce the processing performance and mech. properties of recycled HDPE and PPR materials. The results indicated that with the introduction of the polymer composite, significant enhancement of the recycled materials in the aspects of processability, tensile strength, flexural performance, and impact force could be obtained, and the POE-g-MAH/CaCO₃/HDPE polymer composite would contribute to the impressive balance between high rigidity and toughness. In addition, the feasibility and mech. properties of the recycled HDPE-PPR-POE-g-MAH/CaCO₃/HDPE blended system were also studied: with the help of a composite microcapsule, the gap of mech. capacity between recycled and non-recycled materials was further reduced, and such a blended system was capable of being commercialized in the piping industry. In the experiment, the researchers used many compounds, for example, 2,2-Bis(((3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoyl)oxy)methyl)propane-1,3-diyl bis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoate) (cas: 6683-19-8Electric Literature of C73H108O12).

Peptidyl allyl sulfones: a new class of inhibitors for clan CA cysteine proteases was written by Goetz, Marion G.;Caffrey, Conor R.;Hansell, Elizabeth;McKerrow, James H.;Powers, James C.. And the article was included in Bioorganic & Medicinal Chemistry in 2004.Application of 87694-53-9 This article mentions the following:

A new series of peptidyl allyl sulfone inhibitors was discovered while trying to synthesize epoxy sulfone inhibitors from vinyl sulfones using basic oxidizing conditions. The various dipeptidyl allyl sulfones were evaluated with calpain I, papain, cathepsins B and L, cruzain and rhodesain and found to be potent inhibitors. In comparison to the previously developed class of vinyl sulfone inhibitors, the novel dipeptidyl allyl sulfones were more potent inhibitors than the corresponding dipeptidyl vinyl sulfones. It was observed that the stereochem. of the vinyl sulfone precursor played a role in the potency of the dipeptidyl allyl sulfone inhibitor. In the experiment, the researchers used many compounds, for example, (S)-tert-Butyl (1-(methoxy(methyl)amino)-1-oxo-3-phenylpropan-2-yl)carbamate (cas: 87694-53-9Application of 87694-53-9).

Neryl acetate synthesis from nerol esterification with acetic anhydride by heterogeneous catalysis using ion exchange resin was written by Zeferino, Rubieli Carla Frezza;Piaia, Vinicius Aleixo Angonese;Orso, Vinicius Tres;Pinheiro, Vitor Machado;Zanetti, Micheli;Colpani, Gustavo Lopes;Padoin, Natan;Soares, Cintia;Fiori, Marcio Antonio;Riella, Humberto Gracher. And the article was included in Journal of Industrial and Engineering Chemistry (Amsterdam, Netherlands) in 2022.COA of Formula: C12H20O2 This article mentions the following:

This work aims to synthesize neryl acetate from the nerol esterification reaction with acetic anhydride through heterogeneous catalysis using the ion exchange resin Lewatit GF 101. The reaction was monitored by gas chromatog. and the neryl acetate chem. structure was confirmed by mass spectrometry and NMR spectroscopy. The variables effect on the neryl acetate synthesis was evaluated from an exptl. design anal. The reaction showed the highest combined values for nerol conversion (98.11%) and neryl acetate selectivity (86.10%) at 30 min within optimal exptl. conditions of temperature at 40°C, catalyst content at 7% wt, molar ratio at 1:4 (nerol: acetic anhydride), agitation speed at 250 rpm and nerol content at 3 mmol. The complete nerol conversion was achieved at 40 min with 82.34% selectivity. The reaction rate was controlled only by the nerol decay, an expected behavior due to the excess of acetic anhydride used. In addition, the value obtained for the main reaction kinetic constant found by a pseudo-homogeneous model was 6 times greater than that of the parallel reaction. The catalyst reuse was investigated and after 3 cycles a high conversion (96.68%) and selectivity (83.78%) were observed indicating a low loss of the catalytic activity. In the experiment, the researchers used many compounds, for example, (E)-3,7-Dimethylocta-2,6-dien-1-yl acetate (cas: 105-87-3COA of Formula: C12H20O2).

(E)-3,7-Dimethylocta-2,6-dien-1-yl acetate (cas: 105-87-3) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.
