Nitrogen-containing heteroarene motifs are found in numerous pharmaceuticals, natural products, and synthetic materials. Although several elegant methods for synthesis of these compounds through dehydrogenation of the corresponding saturated heterocycles have been reported, some of the methods are hampered by long reaction times, harsh conditions, and the need for catalysts that are not readily available. This work reports a novel method for dehydrogenation of N-heterocycles. Specifically, O2.? generated in situ acts as the oxidant for N-heterocycle substrates that are susceptible to oxidation through a hydrogen atom transfer mechanism. This method provides a general, green route to N-heteroarenes.

Paragraph 0034-0036, (2017/04/29)
The invention provides 2-substituted-beta-carboline compounds and application thereof in preparing drugs for preventing or treating tumors. The structural general formula of the compounds is disclosed as Formula I. The compounds have high inhibiting actions on growth of tumor cells, and have approximate activity to the positive control paclitaxel. Part of the compounds have obviously better antitumor activity than the paclitaxel; the IC50 value is less than 1 mu M; and thus, the compounds can become efficient drugs for treating tumors.

A series of N9-substituted harmine derivatives were synthesized and evaluated for their anticancer activity on a panel of cancer cell lines, their apoptosis induction and their cell cycle effects. The results showed that N9-substituted harmine derivatives had anticancer effects. In particular, N9-haloalkyl derivatives 9a–9c and N9-acyl harmine derivatives 11c and 11d, with IC50values less than 1?μM, were more potent than doxorubicin against A-549 and/or MCF-7 cell lines. Moreover, structure–activity relationships (SARs) indicated that introducing a haloalkyl or benzenesulfonyl group in the N9-position of harmine could significantly increase the anticancer activity. The most active compound (11d) caused cell cycle arrest in the G2/M phase, and induced cell apoptosis in a dose-dependent manner.
