The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. Compound: 3,3′-Diindolylmethane, is researched, Molecular C17H14N2, CAS is 1968-05-4, about Tetrandrine attenuates intestinal epithelial barrier defects caused by colitis through promoting the expression of Occludin via the AhR-miR-429 pathway, the main research direction is tetrandrine intestinal epithelial colitis Occludin AhR miR 429; Occludin; aryl hydrocarbon receptor; colitis; intestinal epithelial barrier; tetrandrine.Name: 3,3′-Diindolylmethane.

The elevated intestinal permeability due to mucosal barrier defects is not only secondary to inflammatory bowel disease but also precedes enteritis. Tetrandrine, a bisbenzyl isoquinoline alkaloid isolated from the dried roots of Stephamis tetlandra S. Moor, was previously demonstrated to ameliorate colitis induced by dextran sulfate sodium (DSS) in mice. Here, we investigate whether and how tetrandrine protects against the disruption of the intestinal epithelial barrier under colitis condition. The data show that oral administration of tetrandrine significantly counteracted the increase of intestinal permeability in DSS-treated mice, enhanced the mRNA and protein expression of Occludin and Claudin1 in the colon, but hardly affected the expression of ZO-1 and Mucin2. In vitro, tetrandrine treatment rescued the decrease of monolayer transmembrane resistance and the increase of epithelial cell permeability induced by TNF-α, upregulated the expression of Occludin, and downregulated the expression of Claudin1 but did not affect the expression of ZO-1. The siRNA of Occludin largely weakened the protective effect of tetrandrine on the epithelial barrier function in Caco-2 cells. MiR-429 mimic obviously counteracted the upregulation of tetrandrine on the expression of Occludin and the amelioration on epithelial barrier defects, in contrast, miR-429 inhibitor showed the opposite effects. The antagonist (CH223191) and siAhR of aryl hydrocarbon receptor (AhR) nearly completely diminished the effects of tetrandrine, including inhibition of the miR429 expression, the upregulation of Occludin expression, and amelioration of intestinal epithelial barrier defects in Caco-2 cells. In colitis mice, CH223191 significantly weakened the protective effect of tetrandrine on colitis and intestinal mucosal barrier and diminished the downregulation on miR-429 expression and the promotion on Occludin expression in the colon. In summary, tetrandrine can attenuate the intestinal epithelial barrier defects in colitis through promoting Occludin expression via the AhR/miR-429 pathway, and it might be used to treat colitis as a barrier protector.

Author is Stewart, Constantine A.; Arduengo, Anthony J. III.

L (I) reacted with (COD)PtI2 (COD = 1,5-cyclooctadiene) in toluene to give cis-PtL2I2 in which L coordinates through the Sb atom. L reacted with trans-[MePt(PPh3)2(Me2CO)]SbF6 in ether to give trans-MePt(PPh3)2L. trans-MePt(PPh3)2L.0.5(Me3Si)2O is monoclinic, space group P21/c, with a 1246.6(3), b 1752.9(4), c 2749.3(5) pm, β 92.64(2)°, Z = 4, d.(calculated) = 1.49 g cm3, R = 0.065, Rw = 0.090 for 4337 reflections. Changes in the bond angles and lengths in L upon coordination are attributed to steric congestion at the Pt atom due to 2 trans PPh3 ligands. In spite of steric congestion the L system maintains its 10-electron count and planar ligand backbone. NMR data for both complexes require the presence of a stereoactive bond pair at the Sb center.

Hepatocellular carcinoma (HCC) is the leading cause of cancer-related death worldwide with limited treatment options. Biomarker-based active phenolic flavonoids isolated from medicinal plants might shed some light on potential therapeutics for treating HCC. 3,3′-diindolylmethane (DIM) is a unique biol. active dimer of indole-3-carbinol (I3C), a phytochem. compound derived from Brassica species of cruciferous vegetables-such as broccoli, kale, cabbage, and cauliflower. It has anti-cancer effects on various cancers such as breast cancer, prostate cancer, endometrial cancer, and colon cancer. However, the mol. mechanism of DIM involved in reducing cancer risk and/or enhancing therapy remains unknown. The aim of the present study was to evaluate anti-cancer and therapeutic effects of DIM in human hepatoma cell lines Hep3B and HuhCell proliferation was measured with MTT and trypan blue colony formation assays. Migration, invasion, and apoptosis were measured with Transwell assays and flow cytometry analyses. Reactive oxygen species (ROS) intensity and the loss in mitochondrial membrane potential of Hep3B and Huh7 cells were determined using dihydroethidium (DHE) staining and tetramethylrhodamine Et ester dye. Results showed that DIM significantly suppressed HCC cell growth, proliferation, migration, and invasion in a concentration-dependent manner. Furthermore, DIM treatment activated caspasedependent apoptotic pathway and suppressed epithelial-mesenchymal transition (EMT) via ER stress and unfolded protein response (UPR). Taken together, our results suggest that DIM is a potential anticancer drug for HCC therapy by targeting ER-stress/UPR.

Author is Mitra, Bijeta; Ghosh, Pranab.

Humic acid, a biodegradable, non-toxic and easily accessible high mol. weight organocatalyst was explored for straightforward and environmentally benign approach toward preparation of diverse array of functionalized bis(indolyl)methanes I [R = H, 2-pyridyl, 4-MeOC6H4, 3,3-diylindolin-2-one, etc.], bis(pyrazolyl)methanes II [R1 = n-Pr, 4-FC6H4, 3,3-diylindolin-2-one, etc.], bis-coumarins III [R2 = Ph, 2-thienyl, 3-O2NC6H4, etc.] and bis-lawsones IV [R3 = n-hexyl, Ph, 3-pyridyl, etc.] by reaction of a vast range of aldehydes with indole, 3-methyl-1-Ph pyrazolone, 4-hydroxycoumarin and 2-hydroxynaphthalene-1,4-dione resp. under solvent-free condition. These protocols proceeded without any hazardous solvents, toxic metal catalysts and harsh reaction conditions. In addition, low catalyst loading, good yield and excellent functional group tolerance were key advantages of these protocols. The used catalyst and solvent-free approach made this strategy safe to our mother earth. For first time reusability of humic acid was investigated and found that it can be recycled up to fifth run without any significant loss of its activity at end of reaction. Some bioactive mols. such as arundine, trisindoline and vibribdole A were easily synthesized in lab by utilizing this designed strategy.

Synthetic Route of C17H14N2. 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: 3,3′-Diindolylmethane, is researched, Molecular C17H14N2, CAS is 1968-05-4, about Acid condensation products of indole-3-carbinol and their in-vitro (anti)estrogenic, (anti)androgenic and aryl hydrocarbon receptor activities. Author is Amare, Dagnachew Eyachew; Bovee, Toine F. H.; Mulder, Patrick P. J.; Hamers, Astrid; Hoogenboom, Ron L. A. P..

The objective of the study was to investigate the (anti)estrogenic, (anti)androgenic and aryl hydrocarbon receptor (AhR) agonistic activities of a mixture of acid condensation products of indole-3-carbinol, termed RXM, and to identify the compounds most responsible for the observed effects, using in vitro receptor-reporter gene transcriptional activation bioassays. The fraction containing 3,3-diindolylmethane (DIM) displayed a weak estrogenic and relatively strong anti-androgenic activity. DIM was confirmed to be an androgen receptor (hAR) antagonist and a partial estrogen receptor (hERα) agonist. Also the fraction containing the trimer [2-(indol-3-ylmethyl)indol-3-yl]indol-3-ylmethane (LTr1) showed anti-androgenic activities. It was shown for the first time that DIM is not only estrogenic and anti-androgenic, but also possesses anti-estrogenic properties. Though indolo[3,2-b]carbazole (ICZ) is a potent AhR activator and was detected in the RXM, it did not contribute to AhR-agonist activity. Instead, fractions containing the trimers LTr1 and 5,6,11,12,17,18-hexahydrocyclonona[1,2-b:4,5-b:7,8-b]tri-indole (CTr), as well as some unidentified compounds showed the highest AhR activation. The fraction, containing the linear trimer LTr1, showed a weak anti-androgenic activity which has not been reported before. The study demonstrates the importance of a bioassay directed approach for identifying compounds that contribute most to the effects of mixtures

Keywords: polycyclic cycloadduct thermal decomposition bis dihydro thiadiazole methylmaleimide; tetramethyl cyclobutane dithione cycloaddition maleimide; crystal mol structure dihydro thiadiazole cycloadduct methylmaleimide. We’ll tell you more about this compound (cas:4144-22-3).

Thermal decomposition of a mixture of the two stereoisomeric bis(2,5-dihydro-1,3,4-thiadiazoles) cis- and trans-2, which was prepared by treatment of 2,2,4,4-tetramethylcyclobutane-1,3-dithione with excess of diazomethane in the presence of two equivalent of N-methylmaleimide, led to a mixture of three 1:2 cycloadducts. The structures of these thiocarbonyl methanide-adducts have been established by x-ray crystallog. In the presence of only one equivalent of N-methylmaleimide, a complex mixture of the three 1:2 adducts, the known cis- and trans- dispirocyclic bis-thiiranes, and 1:1 adduct, containing one thiirane ring and one fragment resulting from a [2+3]-cycloaddition of a thiocarbonyl methanide, was formed.

Application In Synthesis of 2-((1R,5S)-6,6-Dimethylbicyclo[3.1.1]hept-2-en-2-yl)ethanol. The mechanism of aromatic electrophilic substitution of aromatic heterocycles is consistent with that of benzene. Compound: 2-((1R,5S)-6,6-Dimethylbicyclo[3.1.1]hept-2-en-2-yl)ethanol, is researched, Molecular C11H18O, CAS is 35836-73-8, about The mechanism of formation of 8,8-dimethyl[4.2.1.03,7]nonan-6-yl acetate (fortesyl acetate) during acetolysis of nopyl toluene-p-sulfonate. Author is Al-Qallaf, Fawzia A. H.; Fortes, A. Gil; Johnstone, Robert A. W.; Thompson, Ian; Whittaker, David.

Attempts to prepare 2-(2-hydroxyethyl)-6,6-dimethylbicyclo[3.1.1]hept-2-ene [nopol; (I)] labeled with deuterium at C-10 by a process of oxidation of the primary alc. group of nopol to the aldehyde, followed by H/D exchange and reduction back to alc., were unsuccessful because various oxidation procedures, including reaction with N-chlorosuccinimide at -78 °C, gave instead a carboxylic acid having an oxygen at C-3. I, labeled at C-11 with deuterium, was obtained through a Prins reaction of β-pinene with deuterated paraformaldehyde. This labeled nopol was converted into its toluene-p-sulfonate ester, was solvolyzed in acetic acid containing acetate ion to give 8,8-dimethyltricyclo[4.2.1.03,7]nonan-6-yl acetate [fortesyl acetate (II)], which is an earlier reported novel fused ring system . The position of the label in the product showed that the mechanism of this deep-seated carbon skeletal rearrangement proceeds through the intermediate formation of a cyclobutane ring, followed by shift of a methylene bridge to expand the original cyclobutane ring and then subsequent expansion of the new cyclobutane ring. Calculations of heats of formation of possible ions involved in these shifts confirm the proposed mechanism as the most likely pathway.
