In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Antiferroptotic Activity of Phenothiazine Analogues: A Novel Therapeutic Strategy for Oxidative Stress Related Disease, published in 2020-11-12, which mentions a compound: 693-67-4, Name is 1-Bromoundecane, Molecular C11H23Br, COA of Formula: C11H23Br.

The synthesis of series of lipophilic phenothiazine analogs I (n = 4, 5, 6, 8) that potently inhibit ferroptosis was reported in the present study. The most promising compounds I exhibited an improved protection compared to the parent phenothiazine against erastin- and RSL3-induced ferroptotic cell death. These analogs have equivalent or better potency than ferrostatin-1 (Fer-1) and liproxstatin-1 (Lip-1), which are among the most potent inhibitors of this regulated cell death described so far. They represent novel lead compounds with therapeutic potential in relevant ferroptosis-driven disease models such as FRDA.

Author is Vereshchagin, Anatoly N.; Gordeeva, Alexandra M.; Frolov, Nikita A.; Proshin, Pavel I.; Hansford, Karl A.; Egorov, Mikhail P..

Novel gemini (tail-head-spacer-head-tail) bis-quaternary ammonium compounds (bis-QACs) I (Hal = Cl, Br, I; n = 7, 8, 9, etc.) with a biphenyl spacer between two pyridinium heads were synthesized and compared with commonly used antiseptics such as benzalkonium chloride (BAC) and chlorhexidine digluconate (CHG). The series of compounds showed high inhibitory activity against five bacterial strains and two fungi. The compounds, which contain C8H17-C10H21 aliphatic tails were best within the series. A counterion change does not affect MIC in general. Cytotoxicity on human embryonic kidney cells and haemolysis were also investigated. Among the bis-QACs, cytotoxic effect was lower for I (Hal = Br; n = 12), which is the closest structural analog of BAC.

Author is Li, Jie; Li, Xiang; Yuan, Yan; Wang, Qi; Xie, Lisi; Dai, Yunlu; Wang, Wenjun; Li, Lin; Lu, Xiaomei; Fan, Quli; Huang, Wei.

The incidence of triple-neg. breast cancer (TNBC) is difficult to predict, and TNBC has a high mortality rate among women worldwide. A theranostics approach is developed for TNBC with ratiometric photoacoustic monitored thiol-initiated hydrogen sulfide (H2S) therapy. The ratiometric photoacoustic (PA) probe (CY) with a thiol-initiated H2S donor (PSD) to form a nanosystem (CY-PSD nanoparticles) is integrated. In this theranostics approach, H2S generated from PSD is sensed by CY based on ratiometric PA signals, which simultaneously pinpoints the tumor region. Addnl., H2S is cytotoxic toward TNBC cells (MDA-MB 231), showing a tumor inhibition rate of 63%. To further verify its pharmacol. mechanism, proteomics anal. was performed on tumors treated with CY-PSD nanoparticles. Cells are killed by the significant mitochondrial dysfunction via suppressed energy supply and apoptosis initiation. Besides, the observed inhibition of oxidative stress also generates the cytotoxicity. Significant Kyoto Encyclopedia of Genes Genomes pathways related to TNBC are inhibited. This H2S theranostics approach updates the current anticancer therapies which brings promise for women suffering malignant breast cancer.

Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 693-67-4, is researched, SMILESS is CCCCCCCCCCCBr, Molecular C11H23BrJournal, Article, Chemistry – A European Journal called Catalytic Asymmetric Fluorination of Copper Carbene Complexes: Preparative Advances and a Mechanistic Rationale, Author is Buchsteiner, Michael; Martinez-Rodriguez, Luis; Jerabek, Paul; Pozo, Iago; Patzer, Michael; Noethling, Nils; Lehmann, Christian W.; Fuerstner, Alois, the main research direction is copper carbene complex catalyst asym fluorination alpha diazoester; asymmetric catalysis; bisoxazoline ligands; carbene complexes; copper; organofluorine compounds.COA of Formula: C11H23Br.

The Cu-catalyzed reaction of substituted α-diazoesters with fluoride gives α-fluoroesters with ee values of up to 95%, provided that chiral indane-derived bis(oxazoline) ligands were used that carry bulky benzyl substituents at the bridge and moderately bulky iso-Pr groups on their core. The apparently homogeneous solution of CsF in C6F6/hexafluoroisopropanol (HFIP) is the best reaction medium, but CsF in the biphasic mixture CH2Cl2/HFIP also provides good results. DFT studies suggest that fluoride initially attacks the Cu- rather than the C-atom of the transient donor/acceptor carbene intermediate. This unusual step is followed by 1,2-fluoride shift; for this migratory insertion to occur, the carbene must rotate about the Cu-C bond to ensure orbital overlap. The directionality of this rotatory movement within the C2-sym. binding site determines the sense of induction. This model is in excellent accord with the absolute configuration of the resulting product as determined by x-ray diffraction using single crystals of this a priori wax-like material grown by capillary crystallization

Martin, Marilyn; Krogh-Jespersen, Mary Beth; Hsu, Martha; Tewksbury, John; Laurent, Michel; Viswanath, Kasi; Patterson, Howard published an article about the compound: cis-Dichlorobis(pyridine)platinum(II)( cas:15227-42-6,SMILESS:[Cl-][Pt+2]([N]1=CC=CC=C1)([Cl-])[N]2=CC=CC=C2 ).Recommanded Product: 15227-42-6. Aromatic heterocyclic compounds can be classified according to the number of heteroatoms or the size of the ring. The authors also want to convey more information about this compound (cas:15227-42-6) through the article.

Luminescence, absorption, and magnetic CD (MCD) experiments are reported for cis- and trans-dichlorobis(pyridine)platinum(II). For the trans isomer, an anal. of the temperature dependence of the lifetimes and luminescence intensities indicates that emission at 605 nm is from 2 excited π* states separated by 240 cm-1. For the cis isomer, time-resolved spectroscopy allowed observation of 2 emission bands at 600 and 700 nm, which were assigned from their lifetimes to π* → d and d → d transitions, resp. Further, temperature dependent lifetime studies show that the 600-nm band (π* → d) is from 2 electronic states separated by 200 cm-1. The absorption spectra of both isomers were measured at room and low temperatures in solution, in glasses, and in KCl pellets. From a comparison with the pyridine and Pt(NH3)2Cl2 absorption and MCD spectra and MO calculations, the observed absorption bands for Pt(py)2Cl2 are assigned as d → d, d → π*, and n, π → π* transitions. For the cis isomer the lowest unoccupied mol. orbital is a d metal orbital.

Author is Cheng, Yarui; Zhang, Tianyuan; Cao, Yangrong; Wang, Li; Chen, Wenli.

Iron is a common cofactor in biol. processes such as respiration, photosynthesis, and nitrogen fixation. The genes isiC and isiD encode unknown proteins, and the growth of ΔisiC and ΔisiD mutants is inhibited under iron-deficient conditions. To study the regulatory mechanisms of IsiC and IsiD during iron starvation, we carried out transcriptome and metabolome sequencing. The Kyoto Encyclopedia of Genes and Genomes (KEGG) anal. showed that the photosynthesis, nitrogen metabolism, and ABC transporter pathways play a vital role in regulating iron deficiency. Upon iron repletion, IsiC and IsiD also have a regulatory effect on these pathways. Addnl., KEGG anal. of the differential metabolites of wild type (WT) and mutants showed that they were all enriched in starch and sucrose metabolism after iron limitation. Weighted gene co-expression network anal. (WGCNA) constructed a co-expression network of differentially expressed genes with phenotypes and metabolites, and finally identified five modules. The turquoise module was pos. correlated with iron deficiency. In contrast, the WT and blue module exhibited a neg. correlation, and the mutants ΔisiC and ΔisiD were pos. correlated with the gray and brown modules, resp. WGCNA also analyzed the relationship between metabolites and phenotypes, and the green module was related to iron starvation. The co-expression network determined the hub genes and metabolites of each module. This study lays a foundation for a better understanding of cyanobacteria in response to iron deficiency.

Through the article, more information about this compound (cas:57399-11-8) is conveyed.

This article focuses on the dehydration of α-hydroxy-tetrazoles, leading to tetraazafulvenes and then to vinylic carbenes that rearrange into ethynyl moieties through the Fritsch-Buttenberg-Wiechell rearrangement. Each step of this sequence was scrutinized, either by examination of the substrate and/or dehydrating agent scope, or through AM1 calculations, to understand the limiting step of this process. This underrated transformation appears to be a viable alternative to existing methods used for transforming aldehydes into alkynes.

Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: 1-Bromoundecane, is researched, Molecular C11H23Br, CAS is 693-67-4, about Inhibition of bacterial growth and galactosyltransferase activity of WbwC by α, ω-bis(3-alkyl-1H-imidazolium)alkane salts: Effect of varying carbon content.Name: 1-Bromoundecane.

A series of compounds was designed and synthesized having two imidazolium rings separated by a polymethylene spacer and having alkyl substituents on each of the imidazolium rings. The compounds were assayed for their effects on the activity of galactosyltransferase WbwC, and also on the growth of Gram-neg. and Gram-pos. bacteria, as well as human cells. The inhibition observed on enzyme activities and cell growth was dependent on the total number of carbons in the spacer and the alkyl substituents on the imidazolium rings. These readily synthesized, achiral compounds have potential as antimicrobial and antiseptic agents.

Author is Jiang, Baishan; Jiang, Jie; Kaltheuner, Ines H.; Iniguez, Amanda Balboni; Anand, Kanchan; Ferguson, Fleur M.; Ficarro, Scott B.; Seong, Bo Kyung Alex; Greifenberg, Ann Katrin; Dust, Sofia; Kwiatkowski, Nicholas P.; Marto, Jarrod A.; Stegmaier, Kimberly; Zhang, Tinghu; Geyer, Matthias; Gray, Nathanael S..

Development of inhibitors targeting CDK12/13 is of increasing interest as a potential therapy for cancers as these compounds inhibit transcription of DNA damage response (DDR) genes. We previously described THZ531, a covalent inhibitor with selectivity for CDK12/13. In order to elucidate structure-activity relationship (SAR), we have undertaken a medicinal chem. campaign and established a focused library of THZ531 analogs. Among these analogs, BSJ-01-175 demonstrates exquisite selectivity, potent inhibition of RNA polymerase II phosphorylation, and downregulation of CDK12-targeted genes in cancer cells. A 3.0 Å co-crystal structure with CDK12/CycK provides a structural rational for selective targeting of Cys1039 located in a C-terminal extension from the kinase domain. With moderate pharmacokinetic properties, BSJ-01-175 exhibits efficacy against an Ewing sarcoma tumor growth in a patient-derived xenograft (PDX) mouse model following 10 mg/kg once a day, i.p. administration. Taken together, BSJ-01-175 represents the first selective CDK12/13 covalent inhibitor with in vivo efficacy reported to date.
