Telomerase has become one of the new popular targets for the development of anti-tumor drugs. Based on the structural characteristics of the BIBR1532 which has entered the stage of clin. research, six series total of 64 new compounds with diverse structural characteristics were designed and synthesized. The inhibitory activity against SGC-7901, MGC-803, SMMC-7721, A375 and GES cell lines and their telomerase inhibitory activity were tested. Among them, eight compounds showed good activity against cancer cells, among them compounds 56, 57 and 59 also showed low toxicity. Some of them showed excellent telomerase inhibitory activity with IC₅₀ values ranging from 0.62μM to 8.87μM. Based on above, in depth structure-activity relationships were summarized, the compounds by replacing Me group with cyanide and retaining amide moiety had good anti-tumor activity, moderate cytotoxicity, and better telomerase inhibitory activity. The results should be used for reference in BIBR1532-based structural optimization for further development of small mol. telomerase inhibitors.

Aryl bromide is one of the most important compounds in organic chem., because it is widely used as synthetic building blocks enabling quick access to a wide array of bioactive mols., organic materials, and polymers via the versatile cutting-edge transformations of C-Br bond. Direct C-H bond functionalization of aryl bromide is considered to be an efficient way to prepare functionalized aryl bromides; however, it is rarely explored possibly due to the relatively low reactivity of aryl bromide toward C-H bond activation. Herein, a palladium-catalyzed coupling reaction between aryl iodide and aryl bromide for preparing brominated biaryl compounds via a silver-mediated C-H bond activation pathway is reported.

Polymeric carbon nitrides (PCNs) have emerged as promising heterogeneous photocatalysts for organic transformations as they are metal-free, inexpensive, and possess tunable bandgaps, with excellent chem. stability and photo-stability. However, current application of PCNs in organic synthesis is rather limited to several well-established materials, which limits the scope of reaction patterns and efficiency. We herein report the synthesis and fabrication of two PCN nanosheets by incorporating nanostructure construction, element doping, and vacancy engineering into one hybrid platform. The heteroatom doped PCN nanosheets with vacancies feature highly porous structures with extremely large substrate-catalyst interface areas and enhanced charge separation The generated heterogeneous catalysts demonstrate impressive photoredox catalytic performances in a variety of organic transformations (e.g., defluoroborylation; [2+2] cycloaddition; C-N, C-S, C-O cross-couplings; and an unprecedented regioselective hydrosilylation), providing efficiencies comparable to reported optimized homogeneous catalysts and exceeding those with commonly utilized PCNs.

Achieving C3-selective pyridine functionalization is a longstanding challenge in organic chem. The existing methods, including electrophilic aromatic substitution and C-H activation, often require harsh reaction conditions and excess pyridine and generate multiple regioisomers. Herein, authors report a method for borane-catalyzed tandem reactions that result in exclusively C3-selective alkylation of pyridines. These tandem reactions consist of pyridine hydroboration, nucleophilic addition of the resulting dihydropyridine to an imine, an aldehyde, or a ketone, and subsequent oxidative aromatization. Because the pyridine is the limiting reactant and the reaction conditions are mild, this method constitutes a practical tool for late-stage functionalization of structurally complex pharmaceuticals bearing a pyridine moiety.
