N -aminopyridinium salts as precursors for N-centered radicals – Direct amidation of arenes and heteroarenes

Readily prepared N-aminopyridinium salts are valuable precursors for the generation of N-centered radicals. Reduction of these salts by single electron transfer allows for clean generation of amidyl radicals. It is shown that direct radical C-H amination of heteroarenes and arenes can be achieved with N-aminopyridinium salts under mild conditions by using photoredox catalysis.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Application In Synthesis of 3-Indoleethanol, you can also check out more blogs about526-55-6

Development and Scale-up of a Route to ATR Inhibitor AZD6738

AZD6738 is currently being tested in multiple phase I/II trials for the treatment of cancer. Its structure, comprising a pyrimidine core decorated with a chiral morpholine, a cyclopropyl sulfoximine, and an azaindole, make it a challenging molecule to synthesize on a large scale. We describe the evolution of the chemical processes, following the manufacture of AZD6738 from the initial scale-up through to multikilos on plant scale. During this evolution, we developed a biocatalytic process to install the sulfoxide with high enantioselectivity, followed by introduction of the cyclopropyl group first in batch, then in a continuous flow plate reactor, and finally through a series of continuous stirred tank reactors. The final plant scale process to form AZD6738 was operated on 46 kg scale with an overall yield of 18%. We discuss the impurities formed throughout the process and highlight the limitations of this route for further scale-up.

Indolyl Azaspiroketal Mannich Bases Are Potent Antimycobacterial Agents with Selective Membrane Permeabilizing Effects and in Vivo Activity

The inclusion of an azaspiroketal Mannich base in the membrane targeting antitubercular 6-methoxy-1-n-octyl-1H-indole scaffold resulted in analogs with improved selectivity and submicromolar activity against Mycobacterium tuberculosis H37Rv. The potency enhancing properties of the spiro-fused ring motif was affirmed by SAR and validated in a mouse model of tuberculosis. As expected for membrane inserting agents, the indolyl azaspiroketal Mannich bases perturbed phospholipid vesicles, permeabilized bacterial cells, and induced the mycobacterial cell envelope stress reporter promoter piniBAC. Surprisingly, their membrane disruptive effects did not appear to be associated with bacterial membrane depolarization. This profile was not uniquely associated with azaspiroketal Mannich bases but was characteristic of indolyl Mannich bases as a class. Whereas resistant mycobacteria could not be isolated for a less potent indolyl Mannich base, the more potent azaspiroketal analog displayed low spontaneous resistance mutation frequency of 10-8/CFU. This may indicate involvement of an additional envelope-related target in its mechanism of action.

Determination of enantiomeric purity of commercial 14C- and 3H- labeled L-alpha-amino acids

The enantiomeric purity of twelve commercial 14C- and 3H-labeled L- alpha-amino acids was determined using reverse isotope dilution analysis. The technique utilized reversed-phase (RP) thin-layer chromatography (TLC) and beta-cyclodextrin (beta-CD) in the mobile phase to separate D- and L-amino acids as their 5-dimethylamino-1-naphthalene sulfonyl (dansyl, DNS) derivatives. In all cases, the L-amino acid was contaminated with the D- isomer. This is the first report of the resolution of N-DNS-DL-tyrosine and N-(alpha)-DNS-DL-lysine using this methodology.

An experimental and theoretical study on the prototropic equilibria of the four carboline isomers

We have determined the experimental pK(a)s for the pyridine protonation and pyrrole deprotonation equilibria of the four isomeric (alpha-, beta-, gamma-, and delta-) carbolines (pyridoindoles) and for the deprotonation of their N-pyrido methylated derivatives. HF 6-31+G* ab initio calculations have been carried out to obtain theoretically the magnitudes of the prototropic equilibria ion gas phase and in solution. A cavity model of solvation has been employed. To analyze the influence of annelation and tautomerism, prototropic equilibria of azaindole isomers and H-pyrido tautomers of carbolines, respectively, have also been theoretically studied. Equilibria involving tautomeric species are always energetically unfavored against those of the normal forms. Solvation differently affects the relative gas phase values among isomers within the series and between the same isomers of related series. Solvent damps the magnitude of the gap among azaindole or carboline isomers and can even reverse the acidity sequence. The acidity sequence of theoretical free energies for the pyridine nitrogen deprotonation (gamma < beta < delta < alpha) and pyrrole nitrogen deprotonation (delta < beta < alpha < gamma) processes of the carboline normal forms in solution at 298 K are in quite reasonable agreement with those observed experimentally. Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Recommanded Product: 272-49-1, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 272-49-1, in my other articles.

A short synthesis of the endogenous plant metabolite 7-hydroxyoxindole-3-acetic acid (7-OH-OxIAA) using simultaneous C-H borylations

Methyl indole-3-acetate undergoes two simultaneous iridium-catalysed borylations to deliver exclusively 2,7-diboronate, with the ligand 3,4,7,8-tetramethyl-1,10-phenanthroline (Me4Phen) pivotal in driving the diborylation to completion. Subsequent oxidation-hydrolysis of the diboronate provides methyl 7-hydroxyoxindole-3-acetate which upon hydrolysis of the ester delivers 7-OH-OxIAA, an antioxidant, endogenous metabolite of indole-3-acetic acid found in various types of corn. This route has an overall yield of 50%, involves a single chromatographic purification and is an efficient alternative to existing syntheses, made possible by executing simultaneous oxidations at the indole C2 and C7 sites.

Synthesis, Evaluation, and Mechanism Study of Novel Indole-Chalcone Derivatives Exerting Effective Antitumor Activity Through Microtubule Destabilization in Vitro and in Vivo

Twenty-nine novel indole-chalcone derivatives were synthesized and evaluated for antiproliferative activity. Among them, 14k exhibited most potent activity, with IC50 values of 3-9 nM against six cancer cells, which displayed a 3.8-8.7-fold increase in activity when compare with compound 2. Further investigation revealed 14k was a novel tubulin polymerization inhibitor binding to the colchicine site. Its low cytotoxicity toward normal human cells and nearly equally potent activity against drug-resistant cells revealed the possibility for cancer therapy. Cellular mechanism studies elucidated 14k arrests cell cycle at G2/M phase and induces apoptosis along with the decrease of mitochondrial membrane potential. Furthermore, good metabolic stability of 14k was observed in mouse liver microsomes. Importantly, 14k and its phosphate salt 14k-P inhibited tumor growth in xenograft models in vivo without apparent toxicity, which was better than the reference compound CA-4P and 2. In summary, 14k deserves consideration for cancer therapy.
