Bromination of 10-Phenylphenothiazine and 10-Phenylphenoxazine

The reaction of either 10-phenylphenothiazine (1) with bromine in acetic acid or the cation radical of 1 with bromide ion gives ring substitution only and in accord with customary stoichiometry for nucleophilic substitution of aromatic cation radicals.However, the reaction of 1 with pyridinium bromide perbromide (2) gives predominantly 10-phenyl ring substitution and a small amount of ring substitution products.Evidence is presented which indicates that ring substitution occurs via cation radical whereas 10-phenyl substitution proceeds via electrophilic attack on the neutral molecule 1.Substitution of 10-phenylphenoxazine (4) occurs predominantly but not exclusively on the phenoxazine ring; some bromination does occur on the 10-phenyl ring.In contrast, the reaction of 4 with bromine gives only ring mono- and disubstitution products.These results indicate that both 1 and 4 react similarly under the same conditions.

We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of Reference of 3939-23-9, and how the biochemistry of the body works.Reference of 3939-23-9

A metal- and oxidizing-reagent-free anodic para-selective amination of anilines with phenothiazines

A highly para-selective amination of anilines with phenothiazines for producing various functionalized 10-aryl-10H-phenothiazines is reported. The oxidative amination reaction proceeds electrochemically at room temperature, thereby avoiding the use of metals and oxidizing reagents with excellent functional group tolerance and broad substrate scope.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about Related Products of 38642-74-9 is helpful to your research. Related Products of 38642-74-9

1,2-Didehydrophenothiazines: Preparation of 1-Alkyl and 1-Aryl-substituted Phenothiazines by Lithium-directed Alkylation

A general route to 1-alkyl substituted phenothiazines is described.Reactions of 2-chlorophenothiazine with an excess of methyl-, n-butyl-, s-butyl-, t-butyl- or phenyl-lithiums give the corresponding 1-substituted phenothiazines via 10-lithio-1,2-dehydrophenothiazine.Attempts to trap the presumed 1,10-dilithio intermediate failed.The reaction of 1-chlorophenothiazine with s-butyl-lithium results in preferential metallation of the 9-position. 2-Chlorophenothiazine reacts with nitrogen nucleophiles (lithium dialkylamides) to give 2-substituted products.

Discovery of a Plasmodium falciparum Glucose-6-phosphate Dehydrogenase 6-phosphogluconolactonase Inhibitor (R,Z)-N-((1-Ethylpyrrolidin-2-yl)methyl)-2- (2-fluorobenzylidene)-3-oxo-3,4-dihydro-2H-benzo[b][1,4]thiazine-6-carboxamide (ML276) that reduces parasite growth in vitro

A high-throughput screen of the NIH’s MLSMR collection of ?340000 compounds was undertaken to identify compounds that inhibit Plasmodium falciparum glucose-6-phosphate dehydrogenase (Pf G6PD). PfG6PD is important for proliferating and propagating P. falciparum and differs structurally and mechanistically from the human orthologue. The reaction catalyzed by glucose-6-phosphate dehydrogenase (G6PD) is the first, rate-limiting step in the pentose phosphate pathway (PPP), a key metabolic pathway sustaining anabolic needs in reductive equivalents and synthetic materials in fast-growing cells. In P. falciparum, the bifunctional enzyme glucose-6-phosphate dehydrogenase-6- phosphogluconolactonase (Pf GluPho) catalyzes the first two steps of the PPP. Because P. falciparum and infected host red blood cells rely on accelerated glucose flux, they depend on the G6PD activity of PfGluPho. The lead compound identified from this effort, (R,Z)-N-((1-ethylpyrrolidin-2-yl)methyl)-2-(2- fluorobenzylidene)-3-oxo-3,4-dihydro-2H-benzo[b][1,4]thiazine-6-carbox-amide, 11 (ML276), is a submicromolar inhibitor of PfG6PD (IC50 = 889 nM). It is completely selective for the enzyme’s human isoform, displays micromolar potency (IC50 = 2.6 muM) against P. falciparum in culture, and has good drug-like properties, including high solubility and moderate microsomal stability. Studies testing the potential advantage of inhibiting Pf G6PD in vivo are in progress.

Sodium Triethylborohydride-Catalyzed Controlled Reduction of Unactivated Amides to Secondary or Tertiary Amines

The first transition-metal-free catalytic protocol for controlled reduction of amide functions using cheap and bench-stable hydrosilanes as reducing agents has been established. By altering the hydrosilane and solvent, the new method enables the selective cleavage of unactivated C-O bonds in amides and allows the C-N bonds to selectively break via the deacylated cleavage. Overall, this novel process may offer a versatile alternative to current methodologies employing stoichiometric metal systems for the controlled reduction of carboxamides.
