, (2021/04/15)
Marine alkaloids were divided into five categories from the perspective of anti-tumor activity. The optimization process, chemical synthesis, anti-tumor activity evaluation and structure–activity relationship of various compounds were discussed.
PhI(OAc)2/NaX-mediated halogenation providing access to valuable synthons 3-haloindole derivatives

This paper describes a mild phenyliodine diacetate mediated method for selective chlorination, bromination, and iodination of indole C-H bonds using sodium halide as a source for analogous halogenations. The combination of NaX and phenyliodine diacetate provides an invincible system for halogenation of indoles. This protocol was compatible with a wide array of indole substrates and provides straight forward access to potential halogenated arenes.

The human antigen R (HuR) is an RNA-binding protein known to modulate the expression of target mRNA coding for proteins involved in inflammation, tumorigenesis, and stress responses and is a valuable drug target. We previously found that dihydrotanshinone

Simple and efficient synthetic procedures for the selective preparation of 3-bromo/3-chloroindoles and 2,3-dibromo/2,3-dichloroindoles by using 1,3-dibromo-5,5-dimethylhydantoin (DBDMH) and 1,3-dichloro-5,5-dimethylhydantoin (DCDMH) were developed. Using 1,4-dioxane as the solvent, a variety of indoles, treated with 0.55 equiv DBDMH/DCDMH, afford the corresponding 3-bromo/3-chloroindoles selectively in 82-99% yield. In 1,2-dichloroethane (DCE), a series of 2,3-dichloro/2,3-dibromoindoles were selectively obtained in 84-95% yield by treating with DBDMH/DCDMH. All the processes do not need extra catalysts, dry solvents, or harsh reaction conditions.

A series of pyrrolic analogs and two series of regioisomeric pyrazolic analogs of the marine alkaloids granulatimide and isogranulatimide were prepared. The synthesis of the two first ones was based on the condensation reaction of diversely 5-substituted 3-bromoindoles with pyrrole or pyrazole followed by addition of the intermediates on maleimide or dibromomaleimide, respectively, the so-obtained acyclic adducts being finally photocyclized to the desired analogs. Compounds of the last series were obtained by reacting different 5-substituted-indole-3-glyoxylates with N-Boc-pyrazole-3-acetamide and subsequent photochemical cyclization of the adducts. All the compounds were evaluated for their in vitro growth inhibitory properties toward eight cancer cell lines. Several compounds were also assayed for their ability to abrogate the G2-cell cycle checkpoint or to inhibit a panel of Ser/Thr kinases. Lastly, computer-assisted phase-contrast microscopy (quantitative videomicroscopy) revealed that the three most potent compounds (4a, 9a, 9e), with IC50 growth inhibitory concentrations ranging between 10 and 20 μM, displayed cytostatic, not cytotoxic, anticancer effects.

Two series of regioisomeric pyrazolic analogues of the marine alkaloids granulatimide and isogranulatimide were prepared. The synthesis of the first series was based on the condensation reaction of diversely 5-substituted 3-bromoindoles with pyrazole followed by addition of the intermediates on dibromomaleimide, the so-obtained acyclic adducts being finally photochemically cyclised to the desired analogues. Compounds of the second series were obtained by reacting different 5-substituted-indole-3-glyoxylates with N-Boc-pyrazole-3-acetamide and subsequent photochemical cyclisation of the adducts.

Starting from simple indole precursors the synthesis of naphtho[a]carbazoles and benzo[c]carbazoles is described. Key steps include the use of the Suzuki-Miyaura reaction to afford 2- or 3-aryl substituted indoles, as well as a potassium t-butoxide and light assisted aromatic ring-forming reaction.
