Duan, Zhe;Liu, Jingqiu;Niu, Liping;Wang, Jun;Feng, Mingqian;Chen, Hua;Luo, Cheng research published 《 Discovery of DC_H31 as potential mutant IDH1 inhibitor through NADPH-based high throughput screening》, the research content is summarized as follows. IDH1 mutations are early events in the development of IDH-mutant gliomas and leukemias and are associated with various regulation of mol. process. Mutations of active site in IDH1 could lead to high levels of 2-HG and the suppression of cellular differentiation, while these changes can be reversed by mol. inhibitors target mutant IDH1. Here, through inhouse developed enzymic assay-based high throughput screening platform, we discovered DC_H31 as a novel IDH1-R132H/C inhibitor, with the IC₅₀ value of 0.41 μmol/L and 2.7 μmol/L resp. In addition, saturable SPR binding assay indicated that DC_H31 bound to IDH1-R132H/C due to specific interaction. Further computational docking studies and structure-activity relationship (SAR) suggest that DC_H31 could occupy the allosteric pocket between the two monomers of IDH1-R132H homodimer, which accounts for its inhibitory ability. And it is possible to conclude that DC_H31 acts via an allosteric mechanism of inhibition. At the cellular level, DC_H31 could inhibit cell proliferation, promote cell differentiation and reduce the production of 2-HG with a dose-dependent manner in HT1080 cells. Taken together, DC_H31 is a potent selective inhibitor of IDH1-R132H/C both in vitro and in vivo, which can promote the development of more potent pan-inhibitors against IDH1-R132H/C through further structural decoration and provide a new insight for the pharmacol. treatment of gliomas.

In the present work, a promising approach for preparation of bipyridines and their (hetero) aromatic analogs I (Ar = 2-pyridyl, 4-O₂NC₆H₄, quinolin-2-yl, etc.) via a Pd-catalyzed reductive homocoupling reaction with simple piperazine as a ligand is discussed . The combination of Pd(OAc)₂ and piperazine in DMF was observed to form an excellent catalyst system and efficiently catalyzed the homocoupling of azaarenyl halides, in which DMF was used as the solvent without excess reductants although stoichiometric reductant was generally required to generate the low-oxidation-state active metal species in the catalytic cycles. In this case, good to excellent yields of bipyridines were obtained in the presence of 2.5 mol% of Pd(OAc)2 and 5 mol% of piperazine, using K₃PO₄ as a base in DMF at 140°C. The coupling reaction was operationally simple and displayed good substrate compatibility.

Chen, Tao;Li, Wen-Qin;Liu, Zheng;Jiang, Wen;Liu, Tian;Yang, Qing;Zhu, Xiao-Lei;Yang, Guang-Fu research published 《 Discovery of Biphenyl-Sulfonamides as Novel β-N-Acetyl-D-Hexosaminidase Inhibitors via Structure-Based Virtual Screening》, the research content is summarized as follows. Novel insecticidal targets are always in demand due to the development of resistance. OfHex1, a β-N-acetyl-D-hexosaminidase identified in Ostrinia furnacalis (Asian corn borer), is involved in insect chitin catabolism and has proven an ideal target for insecticide development. In this study, structure-based virtual screening, structure simplification, and biol. evaluation are used to show that compounds with a biphenyl-sulfonamide skeleton have great potential as OfHex1 inhibitors. Specifically, compounds 10k, 10u, and 10v have K_i values of 4.30, 3.72, and 4.56μM, resp., and thus, they are more potent than some reported nonglycosyl-based inhibitors such as phlegmacin B₁ (K_i = 26μM), berberine (K_i = 12μM), compound 2 (K_i = 11.2μM), and compound 3 (K_i = 28.9μM). Furthermore, inhibitory kinetic assessments reveal that the target compounds are competitive inhibitors with respect substrate, and based on toxicity predictions, most of them have potent insecticidal properties. The obtained results indicate that the biphenyl-sulfonamide skeleton characterized by simple chem. structure, synthetic tractability, potent activity, and low toxicity has potential for further development in pest management targeting OfHex1.
