SDS of cas: 67929-86-6. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: Methyl 5-methoxyindole-2-carboxylate, is researched, Molecular C11H11NO3, CAS is 67929-86-6, about Synthesis and Biological Evaluation of Indolyl-Pyridinyl-Propenones Having Either Methuosis or Microtubule Disruption Activity. Author is Trabbic, Christopher J.; Overmeyer, Jean H.; Alexander, Evan M.; Crissman, Emily J.; Kvale, Heather M.; Smith, Marcie A.; Erhardt, Paul W.; Maltese, William A..

Methuosis is a form of nonapoptotic cell death characterized by an accumulation of macropinosome-derived vacuoles with eventual loss of membrane integrity. Small mols. inducing methuosis could offer significant advantages compared to more traditional anticancer drug therapies that typically rely on apoptosis. Herein we further define the effects of chem. substitutions at the 2- and 5-indolyl positions on our lead compound I. We have identified a number of compounds that induce methuosis at similar potencies, including an interesting analog having a hydroxypropyl substituent at the 2-position. In addition, we have discovered that certain substitutions on the 2-indolyl position redirect the mode of cytotoxicity from methuosis to microtubule disruption. This switch in activity is associated with an increase in potency as large as 2 orders of magnitude. These compounds appear to represent a new class of potent microtubule-active anticancer agents.

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 Examination of the mechanism of Rh2(II)-catalyzed carbazole formation using intramolecular competition experiments, published in 2009-09-04, which mentions a compound: 67929-86-6, Name is Methyl 5-methoxyindole-2-carboxylate, Molecular C11H11NO3, Recommanded Product: 67929-86-6.

The use of a rhodium(II) carboxylate catalyst enables the mild and stereoselective formation of carbazoles from biaryl azides. Intramol. competition experiments of triaryl azides suggested the source of the selectivity. A primary intramol. kinetic isotope effect was not observed, and correlation of the product ratios with Hammett σ+ values produced a plot with two intersecting lines with opposite ρ values. These data suggest that electronic donation by the biaryl π-system accelerates the formation of rhodium nitrenoid and that C-N bond formation occurs through a 4π-electron-5-atom electrocyclization.
