IDO1 inhibitors have shown promise as immunotherapies for the treatment of a variety of cancers, including metastatic melanoma and renal cell carcinoma. We recently reported the identification of several novel heme-displacing IDO1 inhibitors, including the clin. mols. linrodostat (BMS-986205) and BMS-986242. Both mols. contain quinolines that, while being present in successful medicines, are known to be potentially susceptible to oxidative metabolism Efforts to swap this quinoline with an alternative aromatic system led to the discovery of 2,3-disubstituted pyridines as suitable replacements. Further optimization, which included lowering ClogP in combination with strategic fluorine incorporation, led to the discovery of compound 29 (I), a potent, selective IDO1 inhibitor with robust pharmacodynamic activity in a mouse xenograft model.

Chen, Ying;Xu, Lanting;Jiang, Yongwen;Ma, Dawei research published 《 Assembly of α-(Hetero)aryl Nitriles via Copper-Catalyzed Coupling Reactions with (Hetero)aryl Chlorides and Bromides》, the research content is summarized as follows. α-(Hetero)aryl nitriles are important structural motifs for pharmaceutical design. The known methods for direct synthesis of these compounds via coupling with (hetero)aryl halides suffer from narrow reaction scope. Herein, we report that the combination of copper salts and oxalic diamides enables the coupling of a variety of (hetero)aryl halides (Cl, Br) and Et cyanoacetate under mild conditions, affording α-(hetero)arylacetonitriles via one-pot decarboxylation. Addnl., the CuBr/oxalic diamide catalyzed coupling of (hetero)aryl bromides with α-alkyl-substituted Et cyanoacetates proceeds smoothly at 60°C, leading to the formation of α-alkyl (hetero)arylacetonitriles after decarboxylation. The method features a general substrate scope and is compatible with various functionalities and heteroaryls. Thus, e.g., 4-chloroanisole + Et cyanoacetate → 2-(4-methoxyphenyl)acetonitrile (up to 80%).

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.
