Synthesis, antitumor evaluation, and molecular docking studies of indole?indazolyl hydrazide?hydrazone derivatives

Abstract: A series of ten novel hydrazide?hydrazones linked indole and indazole moieties were designed and synthesized. All the synthesized compounds were evaluated for their cytotoxicity against four human cancer cell lines (HeLa, MDA-MB-231, MCF-7, and A549). Three of the synthesized compounds showed promising cytotoxicity specifically on some of the tested cell lines with IC50 values ranging between 1.93 and 25.6?muM. Further, one compound was identified as a promising drug lead which showed promising cytotoxicity with IC50 value of 1.93?muM towards MCF-7 breast cancer cell line as compared to the standard drug doxorubicin (IC50 value 0.98?muM). While, all these new compounds showed no cytotoxicity on the normal human embryonic kidney cell line, HEK-293. Graphical abstract: [Figure not available: see fulltext.]

Oxidative [3+3] Annulation of Atropaldehyde Acetals with 1,3-Bisnucleophiles: An Efficient Method of Constructing Six-Membered Aromatic Rings, Including Salicylates and Carbazoles

An oxidative [3+3] annulation of atropaldehyde acetals with various 1,3-bisnucleophiles was developed using either N-bromosuccinimide or copper(II) bromide as oxidizing reagent and Br¡ãnsted or Lewis acids as catalyst. The [3+3] annulations can be considered mechanistically as oxidizing reagent-induced acid-acid-catalyzed domino reactions established through the concept of auto-tandem catalysis. Alkyl acetoacetates, alpha-(indol-2-yl)acetate, anilines, 1-methyl-1H-pyrazol-3-amine, ethyl 5-amino-1H-pyrazole-3-carboxylate, and 3-amino-1H-indazole can all be used as 1,3-bisnucleophiles in this type of transformation. The established reactions can very efficiently construct six-membered aromatic rings, including salicylates and carbazoles. A four-step method of synthesizing the anti-inflammatory agent diflunisal was also developed based on the oxidative [3+3] annulation reaction, and the yield was high. (Figure presented.).

Multiple Roles of the Pyrimidyl Group in the Rhodium-Catalyzed Regioselective Synthesis and Functionalization of Indole-3-carboxylic Acid Esters

A regioselective synthesis of indole-3-carboxylic acid esters from anilines and diazo compounds has been realized by making use of the pyrimidyl group-assisted rhodium-catalyzed C-H activation and C-N bond formation. The reaction proceeds under mild conditions, exhibits good functional group tolerance and scalability. Reutilization of the pyrimidyl directing group in the resulting products provided an efficient strategy for further C-7 functionalization of indoles. Moreover, the pyrimidyl moiety could be readily removed as a leaving group to offer various free N-H indoles.
