One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, such as the rate of change in the concentration of reactants or products with time. 487021-52-3, Name is AR-A014418, formurla is C12H12N4O4S. In a document, author is Shukla, Gaurav, introducing its new discovery. Product Details of 487021-52-3.

A visible-light-mediated concomitant C3 oxidation and C2 amination of indoles has been achieved at room temperature using an Ir (III) photocatalyst. This reaction proceeds without an isatin intermediate via the attack of a singlet oxygen at the C3 position followed by C2 amination leading to difunctionalization of indoles.

Indole-based chalcones have been identified as interesting compounds with anticancer properties. In the present study, we report the synthesis and evaluation of new 1-methoxyindole and 2-alkoxyindole chalcone hybrids as antiproliferative agents active against colorectal carcinoma cell line. Among the 19 investigated molecules, four inhibit the proliferation of colorectal cancer cells HCT-116 with IC50 values <8 mu M and display low cytotoxicity to fibroblast cell line 3T3. The UV-visible, CD and fluorescence competitive displacement assays with ethidium bromide and Hoechst 33258 performed with two active chalcones demonstrated that investigated chalcones interact with calf thymus (CT) DNA through the groove binding mode. Likewise, the quenching interaction of chalcones with bovine serum albumin (BSA) was studied in vitro under optimal physiological condition (pH = 7.4). The Stern-Volmer constant for chalcone-BSA system was found in the range of 10(5) M-1. Application of 123-08-0, The reactant in an enzyme-catalyzed reaction is called a substrate.

The selective multifunctionalization of indoles by using thiosulfonates, trimethyl sulfoxonium iodide (Me3SOI), and H2O2 was studied. The reaction of thiosulfonates with Me3SOI and H2O2 produced sulfonyl radicals and an iodination reagent, both of which were incorporated in indoles to form 3-iodo-2-sulfonyl indoles under carefully controlled conditions. The related reaction mechanism and the substrate scope of 3-iodo-2-sulfonyl indoles are presented.
