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.

Safety of Methyl 3-bromopropanoate. Aromatic heterocyclic compounds can also be classified according to the number of heteroatoms contained in the heterocycle: single heteroatom, two heteroatoms, three heteroatoms and four heteroatoms. Compound: Methyl 3-bromopropanoate, is researched, Molecular C4H7BrO2, CAS is 3395-91-3, about A nano-cocktail of an NIR-II emissive fluorophore and organoplatinum(II) metallacycle for efficient cancer imaging and therapy. Author is Ding, Feng; Chen, Zhao; Kim, Won Young; Sharma, Amit; Li, Chonglu; Ouyang, Qingying; Zhu, Hua; Yang, Guangfu; Sun, Yao; Kim, Jong Seung.

The scarcity of efficient imaging technologies for precise cancer treatment greatly drives the development of new nanotheranostic based platforms that enable both diagnostic and therapeutic functions, together in a single formulation. Owing to the complicated physiol. microenvironment, nanosystems designed with the possibility of noninvasive real-time monitoring of therapeutic progression in the second near-IR channel (NIR-II, 1000-1700 nm) could substantially improve the current cancer therapies. Herein, we design a novel NIR-II theranostic nanoprobe, PSY (size ∼110 nm), by incorporating organoplatinum(II) metallacycles P1 and an organic NIR-II mol. dye, SY1030, into the FDA-approved polymer Pluronic F127. Preliminary in vitro and in vivo studies suggest that PSY is capable of being internalized into glioma U87MG-cells with no significant internalization in non-cancerous tissues. In addition, it shows excellent photostability and minimal background for real-time monitoring the process of therapy in the NIR-II region. Furthermore, in U87MG xenografts and orthotopic breast tumor, PSY demonstrat significantly improved anticancer efficacy compared to a clin. approved Pt(II)-based anticancer drug, cisplatin. The engineered nano-cocktail PSY offers a simple strategy for delivering the organoplatinum(II) macrocycle P1 and NIR-II fluorophore SY1030 as a cocktail of diagnostic and therapeutic functions and highlights its promising capacity for future cancer treatment.

Compound: 3395-91-3, is researched, Molecular C4H7BrO2, about Smart carbon dots as chemosensor for control of water contamination in organic media, the main research direction is carbon dot chemosensor water detection organic solvent.COA of Formula: C4H7BrO2.

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.

Application of 3395-91-3. 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 Design, synthesis and biological evaluation of dihydro-2-quinolone platinum(IV) hybrids as antitumor agents displaying mitochondria injury and DNA damage mechanism. Author is Liu, Zhifang; Li, Zuojie; Du, Tao; Chen, Yan; Wang, Qingpeng; Li, Guoshuai; Liu, Min; Zhang, Ning; Li, Dacheng; Han, Jun.

The design of novel platinum(IV) complexes with mitochondria injury competence, besides the DNA damage mechanism, is a promising way to develop new platinum drugs. Herein, dihydro-2-quinolone (DHQLO) as a mitocan was incorporated into the platinum(IV) system for the first time to prepare a new series of DHQLO platinum(IV) compounds Complex 1b could effectively inhibit the proliferation of tumor cells in vitro and in vivo. It accumulated at higher levels in both whole cells and DNA, and easily underwent intercellular reduction to release platinum(II) and DHQLO moieties. The released platinum(II) complex caused serious DNA damage by covalent conjunction with the DNA duplex, and remarkably increased the expression of the γ-H2AX protein. Moreover, 1b also caused serious mitochondria injury to induce mitochondrial membrane depolarization and increase ROS generation. Such actions upon DNA and mitochondria activate the p53 apoptotic pathway synergetically in tumor cells by upregulating the protein p53 and apoptotic proteins caspase9 and caspase3, which efficiently promoted the apoptotic death of tumor cells. Compound 1b with such synergic mechanism exhibited great potential in reversing cisplatin resistance and improving antitumor efficacies.

Formula: C4H7BrO2. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: Methyl 3-bromopropanoate, is researched, Molecular C4H7BrO2, CAS is 3395-91-3, about Byproducts formed During Thiol-Acrylate Reactions Promoted by Nucleophilic Aprotic Amines: Persistent or Reactive?. Author is Drogkaris, Vasileios; Northrop, Brian H..

The nucleophile-initiated mechanism of thiol-Michael reactions naturally leads to the formation of undesired nucleophile byproducts. Three aza-Michael compounds representing nucleophile byproducts of thiol-acrylate reactions initiated by 4-dimethylaminopyridine (DMAP), 1-methylimidazole (MIM), and 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) have been synthesized and their reactivity in the presence of thiolate has been investigated. Spectroscopic anal. shows that each nucleophile byproduct reacts with thiolate to produce a desired thiol-acrylate product along with liberated aprotic amines DMAP, MIM, or DBU, thus demonstrating that these byproducts are reactive rather than persistent. D. functional theor. computations support exptl. observations and predict that a β-elimination mechanism is favored for converting each nucleophile byproduct into a desired thiol-acrylate product, though an SN2 process can be competitive (i. e. within <2.5 kcal/mol) in less polar solvents.

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.

A Journal, Article, Molecules called In vitro evaluation of antiproliferative properties of novel organotin(IV) carboxylate compounds with propanoic acid derivatives on a panel of human cancer cell lines, Author is Pantelic, Nebojsa D.; Bozic, Bojan; Zmejkovski, Bojana B.; Banjac, Nebojsa R.; Dojcinovic, Biljana; Wessjohann, Ludger A.; Kaluderovic, Goran N., which mentions a compound: 3395-91-3, SMILESS is O=C(OC)CCBr, Molecular C4H7BrO2, Quality Control of Methyl 3-bromopropanoate.

The synthesis of novel triphenyltin(IV) compounds, Ph3SnLn (n = 1-3), with oxaprozin (3-(4,5-diphenyloxazol-2-yl)propanoic acid), HL1, and the new propanoic acid derivatives 3-(4,5-bis(4-methoxylphenyl)oxazol-2-yl)propanoic acid, HL2, and 3-(2,5-dioxo-4,4-diphenylimidazolidin-1-yl)propanoic acid, HL3, has been performed. The ligands represent com. drugs or their derivatives and the tin complexes have been characterized by standard anal. methods. The in vitro antiproliferative activity of both ligands and organotin(IV) compounds has been evaluated on the following tumor cell lines: human prostate cancer (PC-3), human colorectal adenocarcinoma (HT-29), breast cancer (MCF-7), and hepatocellular cancer (HepG2), as well as on normal mouse embryonic fibroblast cells (NIH3T3) with the aid of MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-12 diphenyltetrazolium bromide) and CV (crystal violet) assays. Contrary to the inactive ligand precursors, all organotin(IV) carboxylates showed very good activity with IC50 values ranging from 0.100 to 0.758 μM. According to the CV assay (IC50 = 0.218 ± 0.025 μM), complex Ph3SnL1 demonstrated the highest cytotoxicity against the caspase 3 deficient MCF-7 cell line. Inductively coupled plasma mass spectrometry (ICP-MS) anal. indicated a two-fold lower concentration of tin in MCF-7 cells in comparison to platinum. To investigate the mechanism of action of the compound Ph3SnL1 on MCF-7 cells, morphol., autophagy and cell cycle anal., as well as the activation of caspase and ROS/RNS and NO production, has been performed. Results suggest that Ph3SnL1 induces caspase-independent apoptosis in MCF-7 cells.
