Discovery of a novel indole pharmacophore for the irreversible inhibition of myeloperoxidase (MPO)

Myeloperoxidase (MPO) activity and subsequent generation of hypochlorous acid has been associated with the killing of host-invading microorganisms (e.g. bacteria, viruses, and fungi). However, during oxidative stress, high MPO activity can damage host tissue and is linked to several chronic inflammatory conditions. Herein, we describe the development of a novel biaryl, indole-pyrazole series of irreversible mechanism-based inhibitors of MPO. Derived from an indole-containing high-throughput screen hit, optimization efforts resulted in potent and selective 6-substituted indoles with good oral bioavailability and in vivo activity.

Cp*Rh(III)-Catalyzed C-H Bond Difluorovinylation of Indoles with alpha,alpha-Difluorovinyl Tosylate

Unprecedented Rh(III)-catalyzed C-H bond difluorovinylation of indoles has been successfully developed, and this method provided an example of direct difluorovinylation reaction through C-H bond activation which was rarely reported. In this context, N-ethoxycarbamoyl served as the directing group and 2,2-difluorovinyl tosylates were used for the construction of difluorovinyl-substituted indoles.

Transition-Metal-Free Synthesis of 1,2-Disubstituted Indoles

Herein, we report a new transition-metal-free robust and cost-effective method for synthesis of 1,2-disubstituted indoles from easily available unactivated (i.e. without EWG, PPh3 or SiR3 groups) tertiary amides. Scope of synthetic applicability of the presented protocol was shown on 23 examples of 1,2-disubstituted indoles with different substitution patterns obtained in good to excellent yields. The reported method turned out to be especially effective for synthesis of N-arylated 2-CF3-indoles. Moreover, this approach can be performed in a one-pot two-step manner directly from commercially available secondary amines. Mechanistic studies showed that acyl transfer might be an important step in the course of the reaction. Viability of the presented approach for benzofurans and benzothiophenes synthesis was also discussed.

One-pot sequential synthesis of 3-carbonyl-4-arylbenzo[f]indole and 3-carbonyl-4-arylnaphthofuran fluorophores

The development of novel methods for the construction of valuable fluorophores, 3-carbonyl-4-arylbenzo[f] indoles and 3-carbonyl-4-arylnaphthofurans, is described. In this protocol, the important polycarbonyl key intermediate was generated via the ketonization of ortho-alkynylarylketone tethered with a 1,3-dicarbonyl moiety. This intermediate reacted with an amine to selectively form a pyrrole intermediate, followed by cyclization in acetic acid to provide 3-carbonyl-4-arylbenzo[f] indole. Importantly, these conditions did not cause any epimerization of the stereogenic center in chiral amine substrates. Moreover, the polycarbonyl intermediate could also be utilized to prepare 3-carbonyl-4-arylnaphthofuran using In (OTf) 3 as a catalyst for double cyclization under thermal conditions. In addition, the fluorescence properties of both fluorophores were also studied.

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. you can also check out more blogs about 574-98-1. HPLC of Formula: C10H8BrNO2.

Two C(sp(3))-F Bond Activation in a CF3 Group: ipso-Defluorinative Amination Triggered 1,3-Diamination of (Trifluoromethyl)alkenes with Indoles, Carbazoles, Pyrroles, and Sulfonamides

A novel strategy enabled cleavage of two C(sp(3))-F bonds in a CF3 group is reported. Triggered by ipso-defluorinative amination, this 1,3-diamination of (trifluoromethyl)alkenes with indoles, carbazoles, pyrroles, and sulfonamides gave acyclic 1,3-diamine products bearing a monofluoroalkene moiety in high yields with good to excellent Z/E selectivities. Preliminary mechanistic studies enable the isolation of the reaction intermediate and indicate that a unique sequential ipso-/gamma-selective defluorinative amination pathway is involved in this transformation.

2-Phenylindole derivatives as anticancer agents: synthesis and screening against murine melanoma, human lung and breast cancer cell lines

Indole derivatives have attractive anticancer properties and may be a future hope for better anticancer drug(s) of low toxicity and high potency. In this paper, syntheses of 2-phenylindole derivatives have been described via Fischer indole synthesis through a one-pot solvent-free method. The synthesized compounds were screened for anticancer potential in vitro against murine melanoma (B16F10), human lung cancer (A549), and human breast cancer (MDA-MB-231) cell lines. The results highlighted that 2-phenylindole derivatives are also promising anticancer agents in case of melanoma and lung cancer along with the breast cancer. Molecular docking analyses with possible targets for melanoma (NEDD4-1) and lung cancer (EGFR) were also performed to understand specific interactions of 2-phenylindole derivatives with the amino acid residues of the receptors.

Synthesis, characterization and electrochemical properties of some biologically important indole-based-sulfonamide derivatives

A new series of indole-based-sulfonamide derivatives (A1-A8) was synthesized by treating 5-fluoro-1H-indole-3-carbohydrazide with different aryl-sulfonyl chloride in the presence of pyridine. All synthesized derivatives (A1-A8) were characterized by different analytical methods. The electrochemical behavior of these compounds (A1-A8) was investigated in detail using cyclic voltammetry (CV) and square wave voltammetry (SWV) at the pencil graphite electrode (PGE). In the present study, the redox behavior of all derivatives varies due to the nature of substitutions in the indole sulfonamide moiety. Various fundamental electrochemical parameters, including the standard heterogeneous rate constants (k(s)), and the electroactive surface coverage (Gamma) were calculated from the obtained CVs. The obtained results shed light on the understanding of structure-activity relationships of this class of compounds.
