Name: 3,3′-Diindolylmethane. The mechanism of aromatic electrophilic substitution of aromatic heterocycles is consistent with that of benzene. Compound: 3,3′-Diindolylmethane, is researched, Molecular C17H14N2, CAS is 1968-05-4, about Strain-specific altered nicotine metabolism in 3,3′-diindolylmethane (DIM) exposed mice. Author is Bloom, A. Joseph; Upadhyaya, Pramod; Kharasch, Evan D..

Two indole compounds, indole-3-carbinol (I3C) and its acid condensation product, 3,3′-diindolymethane (DIM), have been shown to suppress the expression of flavin-containing monooxygenases (FMO) and to induce some hepatic cytochrome P450s (CYPs) in rats. In liver microsomes prepared from rats fed I3C or DIM, FMO-mediated nicotine N-oxygenation was decreased, whereas CYP-mediated nicotine metabolism to nicotine iminium and subsequently to cotinine was unchanged. Therefore, it was hypothesized that in mice DIM would also suppress nicotine N-oxygenation without affecting CYP-mediated nicotine metabolism Liver microsomes were produced from male and female C57BL/6 J and CD1 mice fed 2500 ppm (ppm) DIM for 14 days. In liver microsomes from DIM-fed mice, FMO-mediated nicotine N-oxygenation did not differ from the controls, but CYP-mediated nicotine metabolism was significantly increased, with results varying by sex and strain. To confirm the effects of DIM in vivo, control and DIM-fed CD1 male mice were injected s.c. with nicotine, and the plasma concentrations of nicotine, cotinine and nicotine-N-oxide were measured over 30 min. The DIM-fed mice showed greater cotinine concentrations compared with the controls 10 min following injection. It is concluded that the effects of DIM on nicotine metabolism in vitro and in vivo differ between mice and rats and between mouse strains, and that DIM is an effective inducer of CYP-mediated nicotine metabolism in commonly studied mouse strains.

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Direct Construction of Diverse Polyheterocycles Bearing Pyrrolidinediones via Rh(III)-Catalyzed Cascade C-H Activation/Spirocyclization, published in 2019, which mentions a compound: 4144-22-3, mainly applied to quinazolinone maleimide rhodium catalyst tandem Michael reaction spirocyclization; spiroisoindoloquinazolinepyrrolidine trione preparation; spiropolyheterocycle preparation, COA of Formula: C8H11NO2.

Rh(III)-catalyzed cascade oxidative annulation of 2-arylquinazolinones with various maleimides to afford spiroisoindoloquinazolinones bearing pyrrolidinediones was described. Sequential ortho C-H functionalization and spirocyclization via aza-Michael addition result in the formation of both C-C and C-N bonds in a single operation. This atom- and step-economic strategy provides an efficient and novel approach for the syntheses of diverse polyheterocycles bearing pyrrolidinediones, starting from 2-heteroarylquinazolinones and 5-arylpyrazolopyrimidinones, in good to excellent yields.

Herein, a general intramol. C(sp3)-H nitrene insertion method for the synthesis of chiral oxazolidin-2-ones as precursors of chiral β-amino alcs was reported. Specifically, the ring-closing C(sp3)-H amination of N-benzoyloxycarbamates with 2 mol% of a chiral ruthenium catalyst provides cyclic carbamates in up to 99% yield and with up to 99% ee. The method was applicable to benzylic, allylic, and propargylic C-H bonds and can even be applied to completely non-activated C (sp3)-H bonds, although with somewhat reduced yields and stereoselectivities. The obtained cyclic carbamates was subsequently be hydrolyzed to obtain chiral β-amino alcs. The method was very practical as the catalyst was easily synthesized on a gram scale and was recycled after the reaction for further use. The synthetic value of the new method was demonstrated with the asym. synthesis of a chiral oxazolidin-2-one as intermediate for the synthesis of the natural product aurantioclavine and chiral β-amino alcs. that are intermediates for the synthesis of chiral amino acids, indane-derived chiral Box-ligands, and the natural products dihydrohamacanthin A and dragmacidin A.

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, Journal of the Chemical Society [Section] A: Inorganic, Physical, Theoretical called Bridge-splitting reactions and far infrared spectra of diene derivatives of palladium(II) and platinum(II) complexes, Author is Crociani, Bruno; Uguagliati, Paolo; Boschi, Tristano; Belluco, Umberto, which mentions a compound: 12266-72-7, SMILESS is I[Pt]I.C1=CCC/C=CCC/1, Molecular C8H12I2Pt, Related Products of 12266-72-7.

Bridge-splitting reactions of complexes of the type [M(diene.OMe)X]2 (M = Pd(II), Pt(II); diene = cycloocta-1,5-diene, dicyclopentadiene; X = Cl, Br) by neutral ligands (L) having N or P as donor atoms are reported. For the products [M(diene.OMe)LX] two structures are possible, i.e., with L cis to the olefinic double bond (A) or trans to it (B). On the basis of far-ir, spectra, structure (A) has been attributed to [Pd(diene.OMe)(py)Cl] and [Pt(diene.-OMe)LX)] (L = pyridine and p-toluidine). Structure (B) has been attributed to [Pt(diene.OMe)(PPh3)X] and to the analogous Pd(II) complexes. From [M(diene.OMe)(py)Cl] the pyridine is displaced by another neutral ligand, whereas the chloride ion is displaced only by an anionic one. The far-ir spectra (500-60 cm.-1) of the dimers [M(diene.OMe)X]2 are reported and the metal-bridging halogen stretching frequencies are assigned on the basis of a Cipoint-group symmetry. The v(M-Clbridging) falls in the range 298-216 cm.-1, v(M-Brbridging 201-148 cm.-1, and v(M-Ibridging) 165-122 cm.-1

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 Modulatory Effect of Indoles on the Expression of miRNAs Regulating G1/S Cell Cycle Phase in Breast Cancer Cells, published in 2020-12-31, which mentions a compound: 1968-05-4, Name is 3,3′-Diindolylmethane, Molecular C17H14N2, Safety of 3,3′-Diindolylmethane.

Indole-3-carbinol (I3C) is a naturally occurring glucosinolate found in Brassica vegetables that is usually converted in gastric acidic environment to the efficient metabolite 3,3′-diindolylmethane (DIM). Both indoles (I3C and DIM) are known chemopreventive agents for various cancers including breast cancer. This study aimed to investigate the influence of both indoles on the tumor suppressor miRNAs (let-7a-e, miR-15a, miR-16, miR-17-5p, miR-19a, and miR-20a) and oncomiRs (miR-181a, miR-181b, miR-210, miR-221, and miR-106a), which are controlling the cell cycle key regulators: cyclin-dependent kinases (CDKs), CDK inhibitor p27Kip1, and cyclin D1. Our results indicated that both indoles generally elevated the expression of the tumor suppressor miRNAs let-7a-e, miR-19a, miR-17-5p, and miR-20a and decreased the expression of the oncomiR list. Both indoles were able to significantly suppress the expression of CDK4 and CDK6 as well as the apoptotic markers Bcl-2 and survivin. Both indoles decreased cyclin-D1 protein, where I3C decreased cytoplasmic and nuclear cyclin-D1 significantly. Cytoplasmic and nuclear P27Kip1 showed overexpression following treatment with I3C higher than that detected following DIM treatment. This study provides a mechanistic elucidation of the previously reported cell cycle arrest by I3C and DIM in breast cancer cells suggesting that this effect could be through modulation of miRNAs expression that, in turn, regulates the genetic network controlling the G1/S phase in cell cycle progression.
