REACTION OF CHLORO DERIVATIVES OF 10-BENZYL- AND 10-(4′-FLUOROBENZYL)PHENOTHIAZINES WITH NITRILES AND AMINES UNDER ARYNE-FORMING CONDITIONS

2-Chloro-10-benzylphenothiazine (1) and 2-chloro-10-(4′-fluorobenzyl)phenothiazine (2) react with aliphatic nitriles (3 and 4) and LDA to yield typical 2-substituted aryne products (9a,b and 9g,h, respectively).However, treatment of 1 with aromatic nitriles (5-8) and LDA supplies 2-(arylmethyl)-1-cyano rearranged nitriles (10c-f), whereas 2, when treated similarly, affords both rearranged nitriles (10i-l) and typical 2-arylated nitrile products (9i-j).An explanation in terms of the effect of substituents on the competing aryne and tandem addition-rearrangement pathways is presented.The crystal structure of one of the rearranged 1-cyanophenothiazines (10c) was obtained and reveals that the molecule adopts the “extra” conformation in which the 10-benzyl group is in the pseudo axial position.The reaction of 1 and 2 with various lithium amides in the corresponding free amine solvents gives the corresponding 2-aminated products (11) and (12) in excellent yields.Both 1-chloro-10-benzylphenothiazine (18) and 1 supply the same product, 10-benzyl-2-N,N-diisopropylaminophenothiazine (11a), when made to react with LDA in diisopropylamine solvent, indicating that each of these reactions proceeds via the same aryne intermediate, and not through the SRN1 mechanism.

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.Reference of 1910-85-6, you can also check out more blogs aboutReference of 1910-85-6

Identification of a non peptidic RANTES antagonist

A series of phenothiazines demonstrating inhibition of RANTES binding to THP-1 cell membranes has been identified. The lead compound RP23618 (IC50 = 3 muM) was found to inhibit specific binding of 125I-RANTES, but not 125I-MCP-1 to THP-1 cell membranes and furthermore to antagonise RANTES, but not MCP-1-induced chemotaxis of THP-1 cells.

The catalyzed pathway has a lower Ea, but the net change in energy that results from the reaction is not affected by the presence of a catalyst. In my other articles, you can also check out more blogs about 38642-74-9.

Transition-metal-free synthesis of phenothiazines from S-2-acetamidophenyl ethanethioate and ortho-dihaloarenes

An efficient cesium carbonate-mediated synthesis of phenothiazine derivatives from S-2-acetamidophenyl ethanethioates and ortho-dihaloarenes has been developed. This protocol affords an efficient approach for the construction of phenothiazine derivatives without the need of transition-metal catalyst or ligand. A plausible mechanism is proposed.

Spectroscopic investigations of vinyl-substituted 10H-phenothiazine

Different 10H-phenothiazine derivatives modified at their 3- and 3,7-positions with conjugated electron-deficient pyridine or pyridinium groups using ethenyl linkers are described. Spectral variations of 3-((E)-2-(Methylpyridium-4-yl)vinyl)-10H-phenothiazine iodide and 3,7-bis((E)-2-(Methylpyridium-4-yl)vinyl)-10H-phenothiazine diiodide, which are attributed to intramolecular charge transfer, electronic rearrangement and contact ion-pair mechanisms, were observed to be either base or ion dependent. Depending on the extent of deprotonation of the nitrogen atom in the 10-position of the phenothiazine core, donor-acceptor or push-pull systems provide fluorophore-switching and potential near infrared sensor application.

Synthesis and biological properties of aryl methyl sulfones

A novel group of aryl methyl sulfones based on nonsteroidal anti-inflammatory compounds exhibiting a methyl sulfone instead of the acetic or propionic acid group was designed, synthesized and evaluated in vitro for inhibition against the human cyclooxygenase of COX-1 and COX-2 isoenzymes and in vivo for anti-inflammatory activity using the carrageenan induced rat paw edema model in rats. Also, in vitro chemosensitivity and in vivo analgesic and intestinal side effects were determined for defining the therapeutic and safety profile. Molecular modeling assisted the design of compounds and the interpretation of the experimental results. Biological assay results showed that methyl sulfone compounds 2 and 7 were the most potent COX inhibitors of this series and best than the corresponding carboxylic acids (methyl sulfone 2: IC50 COX-1 = 0.04 and COX-2 = 0.10 muM, and naproxen: IC50 COX-1 = 11.3 and COX-2 = 3.36 muM). Interestingly, the inhibitory activity of compound 2 represents a significant improvement compared to that of the parent carboxylic compound, naproxen. Further support to the results were gained by the docking studies which suggested the ability of compound 2 and 7 to bind into COX enzyme with low binding free energies. The improvement of the activity of some sulfones compared to the carboxylic analogues would be performed through a change of the binding mode or mechanism compared to the standard binding mode displayed by ibuprofen, as disclosed by molecular modeling studies. So, this study paves the way for further attention in investigating the participation of these new compounds in the pain inhibitory mechanisms. The most promising compounds 2 and 7 possess a therapeutical profile that enables their chemical scaffolds to be utilized for development of new NSAIDs.

Ratiometric polymer probe for detection of peroxynitrite and the application for live-cell imaging

Peroxynitrite (ONOO?) is one of the sources of oxidation stress involved in many biological signaling pathways. The role of ONOO? being a double-edged sword in biological systems drives the development of effective detection tools. In this work, a boronate-based polymeric fluorescent probe PB-PVA was synthesized and the probe performance was evaluated. The probe exhibits ratiometric sensing of ONOO? in a range of 0?6 muM. There is good linear relationship between the probe fluorescence intensity ratio and ONOO? concentration. The probe also displays moderate selectivity towards ONOO? over other ROS. Moreover, it is water-soluble and possesses good biocompatibility which aids the imaging of ONOO? in living cells. These properties could make the probe a promising tool in in vitro study related to ONOO?

2-Azaadamantane N-oxyl (AZADO)/Cu Catalysis Enables Chemoselective Aerobic Oxidation of Alcohols Containing Electron-Rich Divalent Sulfur Functionalities

The chemoselective oxidation of alcohols containing electron-rich sulfur functionalities (e.g., 1,3-dithianes and sulfides) into their corresponding carbonyl compounds with the sulfur groups can sometimes be a demanding task in modern organic chemistry. A reliable method for this transformation, which features azaadamantane-type nitroxyl radical/copper catalysis using ambient air as the terminal oxidant is reported. The superiority of the developed method was demonstrated by comparing it with various conventional alcohol oxidation methods.
