A chiral bis(imidazolidine)-containing NCN-pincer palladium complex (tBu-PhBidine-Pd-OTf) was an efficient catalyst for the aza-Friedel-Crafts-type reaction of 1H-indoles with isatin-derived N-Cbz-ketimines to give chiral 3-aminobisindole compounds having differently oxidized indole units with high enantioselectivities.

The first solvent-mediated tunable C3/C7 regio- and enantioselective Friedel-Crafts alkylation of 4-aminoindoles with alpha-ketimino esters has been developed. This catalysis allows the highly regioselective formation of indole C3 and C7 alkylation products, both in high yields (up to 96%) and excellent enantioselectivities (up to 99% ee). Mechanism study revealed that the hydrogen-bonding interactions of the solvents with the catalyst played a vital role for the regioselectivity switch. Furthermore, the corresponding products are indole containing unnatural alpha-amino acid derivatives bearing a quaternary stereocenter and enable many further elaborations.

In a document, author is Alsoufi, Abdulwadood S. M., introducing its new discovery. SDS of cas: 138199-71-0.

Hairy root cultures are an efficient tool for the biotechnological production of plant metabolites and a convenient experimental model for analyzing the effect of various compounds on plant metabolism. In contrast to many other types of in vitro plant cultures, hairy roots do not require an external supply of phytohormones to the medium. Consequently, plant growth regulators such as auxins and cytokinins are rarely used as elicitors in hairy root in vitro cultures; however, they can strongly influence plant defense responses. The aim of this study was to investigate the influence of two auxins: natural indole-3-acetic acid (IAA) and synthetic 1-naphthaleneacetic acid (NAA), as well as two cytokinins: natural kinetin and synthetic 6-benzylaminopurine (BAP) at a concentration of 0.75 mg/L on the metabolism of sterols and triterpenoids in Calendula officinalis hairy roots. Auxins prevented the accumulation of triterpenoid saponins (oleanolic acid glycosides), while cytokinin BAP increased their accumulation by 17% and their release into the culture medium by a factor of 10. Other cytokinins and kinetins increased the sterol levels by 17%, the level of stigmasterol by 15%, and the level of isofucosterol by 7 times.

Aromatic amines were reported to show visible light absorption by the adsorption on TiO2 nanoparticles, enabling visible light responsive photocatalytic reactions. However, the origin of the visible light absorption and the chemisorption structure have not been elucidated in detail yet. Here, we demonstrate experimentally and computationally that the visible light absorption in the TiO2-indole surface complex is attributed to interfacial charge-transfer transitions (ICTT) from the adsorbed indole to TiO2, supporting the chemisorption structure of indole via a Ti-N bond formed by the dehydration reaction with a surface hydroxy group. The ICTT originates from pi(indole)-d(pi)(Ti) electronic couplings through the Ti-N bond.

Background: Indole-3-carbinol, derived from Cruciferous vegetables is an estrogen receptor antagonist considered a preventive agent that is naturally present in diet. There are no previous studies on its effects in human inflammatory breast cancer or canine inflammatory mammary cancer that is the most aggressive type of breast cancer. Methods: The aim of this study was to analyze the effect of indole-3-carbinol on a SCID mice xenograft model of canine inflammatory mammary cancer, using equivalent human oral dose as a preventive therapy in humans for 3 weeks. Results: lndole-3-carbinol treatment decreased tumor proliferation and increased apoptosis, although tumor embolization and liver metastasis were observed in some animals. There was a characteristic subpopulation of lipid-rich cells and increased contents of select steroid hormones in tumor homogenates and serum. Conclusions: Our data reveal for the first time that the ingestion of indole-3-carbinol, as administered, diminishes proliferation and increases apoptosis of tumor cells in an experimental model of inflammatory breast cancer, although this effect could not be enough to avoid the appearance of tumor embolization and metastasis, future clinical trials will be needed to clarify the usefulness of indole-3-carbinol in this cancer and to understand the molecular mechanisms involved.
