Recent advances in the synthesis of biologically active cinnoline, phthalazine and quinoxaline derivatives

In the recent decades, N-heterocycles are widely used as versatile scaffolds for the development of biologically active compounds and considered as one of the privileged structures. Among the various N-heterocycles, benzodiazines, a series of bicyclic heterocycles in which benzene rings are fused with 6-membered heterocycles containing two nitrogens are especially interesting, due to their structural conciseness and usefulness as synthetic intermediates, and suitable physicochemical properties as potential drug candidates and chemical probes. For this reason, a series of synthetic methodologies for benzodiazines has been developed and generally used in organic and medicinal chemistry fields. Interestingly, synthesis of quinazoline, a kind of benzodiazine in which benzene is fused with pyrimidine, has been extensively reviewed, while cinnoline, phthalazine and quinoxaline, benzene fused with pyridazine or pyrazine, have been relatively less investigated. In this review, recent advances in the synthesis of biologically active benzodiazines, benzene ring-fused 6-membered heterocycles with two nitrogen atoms, cinnoline, phthalazine and quinoxaline, will be addressed. In each section, biological activities of various benzodiazines, recently served as novel scaffolds for drug discovery, are briefly summarized for comprehensive understanding of biological and medicinal significance in advance. Moreover, intensive investigation of the synthetic approaches to various benzodiazines such as cinnoline, phthalazine and quinoxaline is followed. It would hopefully be helpful for the readers who have interests in developing novel drug candidates and related useful chemical probes.

11H-Isoquino[4,3-c]cinnolin-12-ones: Novel anticancer agents with potent topoisomerase I-targeting activity and cytotoxicity

Recent studies have identified 2,3-dimethoxy-8,9-methylenedioxy-11-[(2- dimethylamino)ethyl]-11H-isoquino[4,3-c]cinnolin-12-one (1a) as a novel topoisomerase I-targeting agent with potent cytotoxic activity. The effect of varied substituents at the 11-position of 2,3-dimethoxy-8,9-methylenedioxy-11H- isoquino[4,3-c]cinnolin-12-ones on topoisomerase I-targeting activity and cytotoxicity was evaluated. Potent TOP1-targeting activity was observed when the 11-position was substituted with either a 2-(N,N-dimethylamino)ethyl, a 2-(N,N-diethylamino)ethyl, a n-butyl, or a 2-(pyrrolidin-1-yl)ethyl group. The addition of a beta-methyl group to 1a provided an analogue with dramatically reduced TOP1-targeting activity and cytotoxicity. Analogues of 1a wherein the 2-(N,N-dimethylamino)ethyl group was replaced with a (2-tetrahydrofuranyl) methyl, a 2-(piperidin-1-yl)ethyl, or a 2-(4-methylpiperazin-1-yl)ethyl substituent exhibited decreased activity as TOP1-targeting agents. Replacement of the dimethoxy groups of 1a with hydrogen atoms resulted in an analogue with significantly decreased TOP1-targeting activity and cytotoxicity. Removal of both the vicinal dimethoxyl groups and the methylenedioxy moiety resulted in a complete loss of TOP1-targeting activity. The presence of a 9-nitro substituent in place of the 8,9-methylenedioxy group of 1a resulted in a decrease in relative TOP1-targeting activity and cytotoxicity. Compounds 1a and the 11-n-butyl analogue 1d were evaluated for antitumor activity in the human tumor xenograft model using athymic nude mice. The non-estrogen responsive breast tumor cell line MDA-MB-435 was used in these assays. At dose levels that approached its maximum tolerated dose, 1a proved to be effective in inhibiting tumor growth in vivo when administered orally or by ip injection.

Palladium-Catalyzed Hydrocarbonylative Cyclization Enabled by Formal Insertion of Aromatic Ca? N Bonds into Pd-Acyl Bonds

An efficient new formal insertion strategy via combination of reductive elimination and oxidative addition sequence was reported, in which the transient N-acyliminium ions formed via hydrocarbonylation function as key intermediates. This strategy has enabled a novel palladium-catalyzed hydrocarbonylative cyclization of azaarene-tethered alkenes or dienes via sequential insertion of a Ca? C bond, CO, and a Ca? N bond into palladium-hydride bonds. This method provides a new and highly efficient synthetic approach to quinolizinones and its derivatives with extended I-conjugated systems, possessing tunable emission wavelengths and good photoluminescence capabilities.
