Li, YiXiang;Wu, Yong;Qin, ZhengSheng;Wang, Gang;Wu, Yuan;Wang, DongDong;Zhang, YiFan;Wang, XinYe;Wu, ChuanMing;Dong, HuanLi research published 《 Substitution effect on solid parking motif and luminescence of diphenylfuro[2,3-b]quinoxaline isomers》, the research content is summarized as follows. The organic mols. combining light-emitting and charge-transporting property are highly expected. We designed and synthesized a pair of isomers, 2,6-diphenylfuro[2,3-b]quinoxaline (26dPFQ) and 2,7-diphenylfuro[2,3-b]quinoxaline (27dPFQ), and investigated effect of changing substituent position on mol. packing motif, conducting and luminescence feature of resulting materials. In CH₂Cl₂ solution, both isomers, 26dPFQ and 27dPFQ, emit deep blue light with a wavelength of 422 nm and shows photoluminance quantum yield (PLQY) of 58.9% and 48.7%, resp. In crystal, the 26dPFQ employs H-type packing motif and retains blue florescent emission with low PLQY (10.0%) while 27dPFQ adopts J-aggregated packing motif and shows enhanced green fluorescent emission with a PLQY of 55.0%. The organic light-emitting devices for both emitters show deep blue emission, the EL peak at 410 nm for 26dPFQ and 424 nm for 27dPFQ, and resp. presents the maximum EQE of 1.2% and 1.0%. The 26dPFQ shows better charge transport capability over 27dPFQ. Our results suggested 2,6-substitution on furo[2,3-b]quinoxaline core are expected to afford such dual functional materials.

Lei, Hong-Xu;Zhang, KaiLi;Qin, Yu-Xi;Dong, Rong-Jian;Chen, De-Zhan;Zhou, HaiFeng;Sheng, Xie-Huang research published 《 A quantum-chemical approach to develop tetrahydroquinoxaline as potent ferroptosis inhibitors》, the research content is summarized as follows. Ferroptosis is a recently characterized form of regulated necrosis with the iron-dependent accumulation of (phospho)lipid hydroperoxides (LOOH). It has attracted considerable attention for its putative involvement in diverse pathophysiol. processes, such as cardiovascular disease and neurodegeneration. Here we describe the discovery of tetrahydroquinoxaline, a novel scaffold of ferroptosis inhibitors based on quantum chem. methods. Tetrahydroquinoxaline deviates showed very good inhibition of ferroptosis, while being non cytotoxic for human cancer cells. And, the advantage of them is their small mol. weight (MW. = 148 Da) that can be coupled with other drugs to form multi-target drugs to better meet the treatment of complicated diseases.

Larissa;Jennings, Laura E.;Hewings, David S.;Woodhouse, Fern;Reynolds, Jessica K.;Schiedel, Matthias;Humphreys, Philip G.;Biggin, Philip C.;Conway, Stuart J. research published 《 Fragment-Based Identification of Ligands for Bromodomain-Containing Factor 3 of Trypanosoma cruzi》, the research content is summarized as follows. The Trypanosoma cruzi (T. cruzi) parasite is the cause of Chagas disease, a neglected disease endemic in South America. The life cycle of the T. cruzi parasite is complex and includes transitions between distinct life stages. This change in phenotype (without a change in genotype) could be controlled by epigenetic regulation, and might involve the bromodomain-containing factors 1-5 (TcBDF1-5). However, little is known about the function of the TcBDF1-5. Here we describe a fragment-based approach to identify ligands for T. cruzi bromodomain-containing factor 3 (TcBDF3). We expressed a soluble construct of TcBDF3 in E. coli, and used this to develop a range of biophys. assays for this protein. Fragment screening identified 12 compounds that bind to the TcBDF3 bromodomain. On the basis of this screen, we developed functional ligands containing a fluorescence or ¹⁹F reporter group, and a photo-crosslinking probe for TcBDF3. These tool compounds will be invaluable in future studies on the function of TcBDF3 and will provide insight into the biol. of T. cruzi.

Selenium is an underexplored element that can be used for bioisosteric replacement of lower mol. weight chalcogens such as oxygen and sulfur. More studies regarding the impact of selenium substitution in different chem. scaffolds are needed to fully grasp this element′s potential. Herein, we decided to evaluate the impact of selenium incorporation in a series of tryptophan 2,3-dioxygenase (TDO2) inhibitors, a target of interest in cancer immunotherapy. First, we synthesized the different chalcogen isosteres through Suzuki-Miyaura type coupling. Next, we evaluated the isosteres′ affinity and selectivity for TDO2, as well as their lipophilicity, microsomal stability and cellular toxicity on TDO2-expressing cell lines. Overall, chalcogen isosteric replacements did not disturb the on-target activity but allowed for a modulation of the compounds′ lipophilicity, toxicity and stability profiles. The present work contributes to our understanding of oxygen/sulfur/selenium isostery towards increasing structural options in medicinal chem. for the development of novel and distinctive drug candidates.

C.;Mathieu, Caroline;Pilotte, Luc;Stroobant, Vincent;Van den Eynde, Benoit;Frederick, Raphael research published 《 Rational Design of Original Fused-Cycle Selective Inhibitors of Tryptophan 2,3-Dioxygenase》, the research content is summarized as follows. Tryptophan 2,3-dioxygenase (TDO2) is a heme-containing enzyme constitutively expressed at high concentrations in the liver and responsible for L-tryptophan (L-Trp) homeostasis. Expression of TDO2 in cancer cells results in the inhibition of immune-mediated tumor rejection due to an enhancement of L-Trp catabolism via the kynurenine pathway. In the study herein, we disclose a new 6-(1H-indol-3-yl)-benzotriazole scaffold of TDO2 inhibitors developed through rational design, starting from existing inhibitors. Rigidification of the initial scaffold led to the synthesis of stable compounds displaying a nanomolar cellular potency and a better understanding of the structural modulations that can be accommodated inside the active site of hTDO2.

A series of benz-fused five-membered heterocyclic compounds such as I [R¹ = H, Me, Br, etc.; R² = H, Br, NH₂, etc; X = O, S] were designed and synthesized as novel tubulin inhibitors targeting the colchicine binding site.

As epigenetic readers, bromodomain and extra-terminal domain (BET) family proteins bind to acetylated-lysine residues in histones and recruit protein complexes to promote transcription initiation and elongation. Inhibition of BET bromodomains by small mol. inhibitors has emerged as a promising therapeutic strategy for cancer. Herein, we describe our efforts toward the discovery of a novel series of 1-(5-(1H-benzo[d]imidazole-2-yl)-2,4-dimethyl-1H-pyrrol-3-yl)ethan-1-one derivatives as BET inhibitors. Intensive structural modifications led to the identification of compound 35f as the most active inhibitor of BET BRD4 with selectivity against BET family proteins. Further biol. studies revealed that compound 35f can arrest the cell cycle in G₀/G₁ phase and induce apoptosis via decreasing the expression of c-Myc and other proteins related to cell cycle and apoptosis. More importantly, compound 35f showed favorable pharmacokinetic properties and antitumor efficacy in MV4-11 mouse xenograft model with acceptable tolerability. These results indicated that BET inhibitors could be potentially used to treat hematol. malignancies and some solid tumors.
