Recommanded Product: Methyl 3-bromopropanoate. So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic. Compound: Methyl 3-bromopropanoate, is researched, Molecular C4H7BrO2, CAS is 3395-91-3, about Design, synthesis and biological evaluation of pyridyl substituted benzoxazepinones as potent and selective inhibitors of aldosterone synthase.

Exorbitant aldosterone is closely associated with various severe diseases, including congestive heart failure and chronic kidney disease. As aldosterone synthase is the pivotal enzyme in aldosterone biosynthesis, its inhibition constitutes a promising treatment for these diseases. Via a structure-based approach, a series of pyridyl substituted 3,4-dihydrobenzo[f][1,4]oxazepin-5(2H)-ones I (R = dimethylaminyl, F, pyrrolidin-1-yl, etc.; R1 = 4-methylpyridin-3-yl, 5-(trifluoromethyl)pyridin-3-yl, 5-fluoropyridin-3-yl, etc.) were designed as inhibitors of aldosterone synthase. Six compounds I (R = dimethylaminyl, R1 = 5-methylpyridin-3-yl; R1 = R = dimethylaminyl, 4-methylpyridin-3-yl; R = dimethylaminyl, R1 = 5-methoxypyridin-3-yl; R1 = 4-methylpyridin-3-yl, R = morpholin-4-yl; R1 = 4-methylpyridin-3-yl, R = piperazin-1-yl (II); R1 = 4-methylpyridin-3-yl, R = 4-methylpiperazin-1-yl) distinguished themselves with potent inhibition (IC50 <100 nmol/L) and high selectivity over homogenous 11β-hydroxylase. As the most promising compound, (II) exhibited an IC50 of 12 nmol/L and an excellent selectivity factor (SF) of 157, which are both superior to those of the reference fadrazole (IC50 = 21 nmol/L, SF = 7). Importantly, (II) showed no inhibition against steroidogenic CYP17, CYP19 and a panel of hepatic CYP enzymes indicating an outstanding safety profile. As it manifested satisfactory pharmacokinetic properties in rats, compound (II) was considered as a drug candidate for further development.

Name: Methyl 3-bromopropanoate. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. Compound: Methyl 3-bromopropanoate, is researched, Molecular C4H7BrO2, CAS is 3395-91-3, about Cobalt(I)-Catalyzed Borylation of Unactivated Alkyl Bromides and Chlorides. Author is Verma, Piyush Kumar; Prasad, K. Sujit; Varghese, Dominic; Geetharani, K..

A Co-complex-catalyzed borylation of a wide range of alkyl halides with a diboron reagent (B2pin2 or B2neop2) was developed under mild reaction conditions, demonstrating the 1st Co-mediated cross-coupling with alkyl electrophiles. This protocol allows alkyl boronic esters to be accessed from alkyl halides, including alkyl chlorides, which were used rarely as coupling partners. Mechanistic studies reveal the possible involvement of an alkyl radical intermediate in this Co-mediated catalytic cycle.

Computed Properties of C4H7BrO2. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: Methyl 3-bromopropanoate, is researched, Molecular C4H7BrO2, CAS is 3395-91-3, about Synthesis and Biological Validation of a Harmine-Based, Central Nervous System (CNS)-Avoidant, Selective, Human β-Cell Regenerative Dual-Specificity Tyrosine Phosphorylation-Regulated Kinase A (DYRK1A) Inhibitor. Author is Kumar, Kunal; Wang, Peng; Wilson, Jessica; Zlatanic, Viktor; Berrouet, Cecilia; Khamrui, Susmita; Secor, Cody; Swartz, Ethan A.; Lazarus, Michael; Sanchez, Roberto; Stewart, Andrew F.; Garcia-Ocana, Adolfo; DeVita, Robert J..

Recently, our group identified that harmine is able to induce β-cell proliferation both in vitro and in vivo, mediated via the DYRK1A-NFAT pathway. Since, harmine suffers from a lack of selectivity, both against other kinases and CNS off-targets, we therefore sought to expand structure-activity relationships for harmine’s DYRK1A activity, to enhance selectivity for off-targets while retaining human β-cell proliferation activity. We carried out optimization of the 9-N-position of harmine to synthesize 29 harmine-based analogs. Several novel inhibitors showed excellent DYRK1A inhibition and human β-cell proliferation capability. An optimized DYRK1A inhibitor, compound I, was identified as a novel, efficacious in vivo lead candidate. Compound I also demonstrates improved selectivity for kinases and CNS off-targets, as well as in vivo efficacy for β-cell proliferation and regeneration at lower doses than harmine. Collectively, these findings demonstrate that compound I is a much improved in vivo lead candidate as compared to harmine for the treatment of diabetes.

The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: Methyl 3-bromopropanoate(SMILESS: O=C(OC)CCBr,cas:3395-91-3) is researched.Computed Properties of C4H7BrO2. The article 《Smart carbon dots as chemosensor for control of water contamination in organic media》 in relation to this compound, is published in Sensors and Actuators, B: Chemical. Let’s take a look at the latest research on this compound (cas:3395-91-3).

A novel nanoprobe was synthesized by functionalizing gluthatione/citric acid-carbon dots (CDs) with a benzo-isoquinolin-based mol., Me 3-(4-(2-(5-((methylsulfonyl)oxy)pentyl)-1,3-dioxo-2,3-dihydro-1H-benzo[de]isoquinolin-6-yl)piperazin-1-yl)propanoate (water chemosensor, WCS), to detect trace amounts of water in non-aqueous media via on-off fluorescence. The design and synthesis of the free mol. WCS and the functionalized nanoprobe (CD-WCS) are described in detail and as well as their full characterization by different spectroscopic methods. WCS was found to be an excellent indicator of pH in aqueous media and exhibited, in solvents of different polarity, solvatochromic behavior. On the other hand, the modified fluorescence intensity of CD-WCS was found to be an excellent indicator for water in non-aqueous media (organic solvents and oil-based lubricants). In these media, CD-WCS showed weak fluorescence intensity due to a photoinduced electron transfer (PET) process. Sequential addition of trace amount of water led to revival of CD-WCS fluorescence intensity. The fluorescence on-off mechanisms are proposed for WCS in aqueous media as well as for CD-WCS in non-aqueous media. The anal. performance characteristics of CD-WCS showed a limit of detection for water of 0.00021% (volume/volume) in toluene and 0.00014% volume/volume in base-oil lubricant. The potential application of CD-WCS as chemosensor of water contamination in oil-based lubricants as well as green anti-wear/anti-friction lubricant additive are outlined.

Author is Zhang, Ruiping; Wang, Zhenjun; Xu, Liying; Xu, Yuling; Lin, Yi; Zhang, Ying; Sun, Yao; Yang, Guangfu.

Multifunctional probes integrating accurate multi-diagnosis and efficient therapy hold great prospect in biomedical research. However, the sophisticated construction and difficulties in matching the ratios of doses and laser triggers of probes for each modality imaging and therapy are still hindered the extensive practice of multifunctional probes in biomedicine. We herein rational designed an organic dye SY1080 with intrinsic multifunction by both introducing 3,4-ethylenedioxy thiophene (EDOT) and the selenium containing acceptor unit into the backbone to balance the fluorescence brightness and emission wavelength. Under single dose and 808 nm laser irradiation conditions, SY1080 not only carried out NIR-II fluorescence/Photoacoustic imaging of real-time and noninvasive tumor delineation with excellent contrast, but also effectively ablated tumors with laser irradiation to perform PTT under the guidance of dual-modal imaging. These exciting results highlighted SY1080 as a multifunctional and universal phototheranostic platform for potential applications.

After consulting a lot of data, we found that this compound(3395-91-3)Computed Properties of C4H7BrO2 can be used in many types of reactions. And in most cases, this compound has more advantages.
