Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Article, Research Support, N.I.H., Extramural, Research Support, Non-U.S. Gov’t, Gut Microbes called Cruciferous vegetables (Brassica oleracea) confer cytoprotective effects in Drosophila intestines, Author is Lyles, James T.; Luo, Liping; Liu, Ken; Jones, Dean P.; Jones, Rheinallt M.; Quave, Cassandra L., which mentions a compound: 1968-05-4, SMILESS is C1(CC2=CNC3=C2C=CC=C3)=CNC4=C1C=CC=C4, Molecular C17H14N2, COA of Formula: C17H14N2.

Varieties and cultivars of the cruciferous vegetable Brassica oleracea are widely presumed to elicit pos. influences on mammalian health and disease, particularly related to their indole and sulforaphane content. However, there is a considerable gap in knowledge regarding the mechanisms whereby these plant-derived mols. elicit their beneficial effects on the host. In this study, we examined the chem. variation between B. oleracea varieties and evaluated their capacity to both activate Nrf2 in the Drosophila intestine and elicit cytoprotection. Ten types of edible B. oleracea were purchased and B. macrocarpa was wild collected. Fresh material was dried, extracted by double maceration and green kale was also subjected to anaerobic fermentation before processing. Untargeted metabolomics was used to perform Principal Component Anal. Targeted mass spectral anal. determined the presence of six indole species and quantified indole. Extracts were tested for their capacity to activate Nrf2 in the Drosophila intestine in third instar Drosophila larvae. Cytoprotective effects were evaluated using a paraquat-induced oxidative stress gut injury model. A “”Smurf”” assay was used to determine protective capacity against a chem. induced leaky gut. Extracts of Brussels sprouts and broccoli activated Nrf2 and protected against paraquat-induced damage and leaky gut. Lacto-fermented kale showed a cytoprotective effect, increasing survival by 20% over the non-fermented extract, but did not protect against leaky gut. The protective effects observed do not directly correlate with indole content, suggesting involvement of multiple compounds and a synergistic mechanism.

The use of a halogen bond donor to catalyze Friedel-Crafts reactions of indoles with a range of aldehydes and ketones to directly produce bis(indolyl)methanes, including the natural products arsindoline A, arundine, trisindoline, and vibrindole A, is reported. The bidentate catalyst used in these reactions proved to be more effective than a monondentate analog, a thiourea commonly used as an organocatalyst, and even a trityl cation that has been used previously in the synthesis of bis(indolyl)methanes.

Formula: C8H12I2Pt. 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: Diiodo(1,5-cyclooctadiene)platinum(II), is researched, Molecular C8H12I2Pt, CAS is 12266-72-7, about Utilizing Redox-Mediated Bergman Cyclization toward the Development of Dual-Action Metalloenediyne Therapeutics. Author is Lindahl, Sarah E.; Park, Hyunsoo; Pink, Maren; Zaleski, Jeffrey M..

Reaction of 2 equiv of 1,2-bis((diphenylphosphino)ethynyl)benzene (dppeb, 1) with Pt(cod)Cl2 followed by treatment with N2H4 yields the reduced Pt(0) metalloenediyne, I (Pt(dppeb)2, 2). This complex is stable to both air oxidation and metal-mediated Bergman cyclization under ambient conditions due to the nearly idealized tetrahedral geometry. Reaction of 2 with 1 equiv of I2 in the presence of excess 1,4-cyclohexadiene (1,4-CHD) radical trap rapidly and near-quant. generates the cis-Bergman-cyclized, diiodo product II (3, 31P: δ = 41 ppm, JPt-P = 3346 Hz) with concomitant loss of 1 equiv of uncyclized phosphine chelate (31P: δ = -33 ppm). In contrast, addition of 2 equiv of I2 in the absence of addnl. radical trap instantaneously forms a metastable Pt(dppeb)22+ intermediate species, 4, that was characterized by δ = 51 ppm in the 31P NMR (JPt-P = 3171 Hz) and νCC = 2169 cm-1 in the Raman profile, indicating that it is an uncyclized, bis-ligated complex. Over 24 h, 4 undergoes ligand exchange to form a neutral, square planar complex that spontaneously Bergman cyclizes at ambient temperature to give the crystalline product Pt(dppnap-I2)I2 (dppnap-I2 = (1,4-diiodonaphthalene-2,3-diyl)bis(diphenylphosphine)), 5, in 52% isolated yield. Computational anal. of the oxidation reaction proposes two plausible flattened tetrahedral structures for intermediate 4: one where the phosphine core has migrated to a trans-spanning chelate geometry, and a second, higher energy structure (3.3 kcal/mol) with two cis-chelating phosphine ligands (41° dihedral angle) via a restricted alkyne-terminal starting point. While the energies are disparate, the common theme in both structures is the elongated Pt-P bond lengths (>2.4 Å), indicating that nucleophilic ligand substitution by I- is on the reaction trajectory to the cyclized product 5. The efficiency of the redox-mediated Bergman cyclization reaction of this stable Pt(0) metalloenediyne prodrug and resulting cisplatin-like byproduct represents an intriguing new strategy for potential dual-threat metalloenediyne therapeutics.

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: 1968-05-4, is researched, SMILESS is C1(CC2=CNC3=C2C=CC=C3)=CNC4=C1C=CC=C4, Molecular C17H14N2Journal, Article, Research Support, Non-U.S. Gov’t, Toxicology and Applied Pharmacology called AKT inhibitor AZD5363 suppresses stemness and promotes anti-cancer activity of 3,3′-diindolylmethane in human breast cancer cells, Author is Zhu, Kaiyuan; Liu, Xu; Liu, Chunxiao; Xu, Yuting; Fu, Yingqiang; Dong, Wei; Yan, Yadong; Wang, Wenjing; Qian, Cheng, the main research direction is diindolylmethane AKT human breast cancer cell anticancer activity; AKT inhibitor; CyTOF; Stemness.Electric Literature of C17H14N2.

The 3,3′-diindolylmethane (DIM) is a dimer compound converted from Indoly-3-carbinol that had been studied as promising chemo-preventive agent against breast cancer. In this study, we observed that proportion of CD133+Nanog+ subpopulation in MCF-7 cells was significantly increased after DIM administration with up-regulated AKT activity by using CyTOF assay. SPADE anal. revealed this stem-like subpopulation exhibited apoptosis-resistance property against DIM treatment. By combining with AKT inhibitor AZD5363, DIM induced CD133 expression could be suppressed. In addition, a combination treatment of MCF-7 and MDA-MB-231 breast cancer cells with DIM and AZD5363 showed synergistic decreases in cell proliferation and induced apoptosis. Furthermore, results from imaging flow cytometry suggested that FoxO3a nuclear localization and PUMA expression could be improved by combination of AZD5363 with DIM. Taken together, the above observations suggested that the combination of AZD5363 with DIM could be developed as potential therapy for breast cancer.

Compound: 3,3′-Diindolylmethane, is researched, Molecular C17H14N2, CAS is 1968-05-4, about DIM mitigates the development of experimental autoimmune encephalomyelitis by maintaining the stability and suppressive function of regulatory T cells. Author is Yang, Sujuan; Tan, Lixi; Chen, Yingying; Liu, Aiqun; Hong, Mingfan; Peng, Zhongxing.

Recent studies have revealed that indoles, dietary ligands of the aryl hydrocarbon receptor (AhR), have immunomodulatory characteristics of balancing the differentiation of regulatory T cells (Tregs) and Th17 cells in multiple autoimmune diseases. In this study, we aimed to investigate the potency of the indole, 3,3′-diindolylmethane (DIM), on the stability and suppressive function of Tregs in exptl. autoimmune encephalomyelitis (EAE). Furthermore, we used the AhR antagonist CH223191 to verify that DIM exerts its effects on Tregs through the activation of AhR. We found that DIM treatment significantly alleviated the severity of EAE by maintaining the stability and suppressive function of Tregs instead of facilitating the differentiation of Tregs. Thus, these DIM-treated Tregs might indirectly inhibit the generation of Th17 cells and the production of proinflammatory cytokines. And we confirmed the critical role of AhR in the EAE model. Our study further investigated the mechanisms by which dietary indoles promote Treg activity in the EAE model. DIM may act as a novel therapeutic to restrain autoimmune inflammation in multiple sclerosis.
