Compound: 3,3′-Diindolylmethane, is researched, Molecular C17H14N2, CAS is 1968-05-4, about Humic acid: A Biodegradable Organocatalyst for Solvent-free Synthesis of Bis(indolyl)methanes, Bis(pyrazolyl)methanes, Bis-coumarins and Bis-lawsones. 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

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. The structure of the latter has again been proven by x-ray crystallog.

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.

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: 1-(tert-Butyl)-1H-pyrrole-2,5-dione, is researched, Molecular C8H11NO2, CAS is 4144-22-3, about Facile quantitation of free thiols in a recombinant monoclonal antibody by reversed-phase high performance liquid chromatography with hydrophobicity-tailored thiol derivatization. Author is Welch, Leslie; Dong, Xiao; Hewitt, Daniel; Irwin, Michelle; McCarty, Luke; Tsai, Christina; Baginski, Tomasz.

Free thiol content, and its consistency, is one of the product quality attributes of interest during tech. development of manufactured recombinant monoclonal antibodies (mAbs). We describe a new, mid/high-throughput reversed-phase-high performance liquid chromatog. (RP-HPLC) method coupled with derivatization of free thiols, for the determination of total free thiol content in an E. coli-expressed therapeutic monovalent monoclonal antibody mAb1. Initial selection of the derivatization reagent used an hydrophobicity-tailored approach. Maleimide-based thiol-reactive reagents with varying degrees of hydrophobicity were assessed to identify and select one that provided adequate chromatog. resolution and robust quantitation of free thiol-containing mAb1 forms. The method relies on covalent derivatization of free thiols in denatured mAb1 with N-tert-butylmaleimide (NtBM) label, followed by RP-HPLC separation with UV-based quantitation of native (disulfide containing) and labeled (free thiol containing) forms. The method demonstrated good specificity, precision, linearity, accuracy and robustness. Accuracy of the method, for samples with a wide range of free thiol content, was demonstrated using admixtures as well as by comparison to an orthogonal LC-MS peptide mapping method with isotope tagging of free thiols. The developed method has a facile workflow which fits well into both R&D characterization and quality control (QC) testing environments. The hydrophobicity-tailored approach to the selection of free thiol derivatization reagent is easily applied to the rapid development of free thiol quantitation methods for full-length recombinant antibodies.
