Zhang, Hualin;Xie, Ruliang;AI-furas, Hawaa;Li, Yupeng;Wu, Qingxia;Li, Jian;Xu, Fang;Xu, Tianfeng research published 《 Design, Synthesis, and Biological Evaluation of Novel EGFR PROTACs Targeting Del19/T790M/C797S Mutation》, the research content is summarized as follows. The tertiary epidermal growth factor receptor (EGFR) C797S mutation predominates in the acquired mutational resistance in cancer patients to third-generation EGFR inhibitors. Small-mol. inhibitors targeting the EGFR C797S mutation have been developed with good efficiency. However, these compounds may still induce new EGFR mutations to evade the inhibition pathway. One EGFR protein degrader based on an allosteric inhibitor has shown some benefits of degrading the EGFR L858R/T790M/C797S triple mutant. However, the degrader of the other important triple EGFR mutation Del19/T790M/C797S has not been reported. Here we present the design and synthesis of a series of EGFR proteolysis-targeting chimeras (PROTACs) that can rapidly and potently induce EGFR degradation in Ba/F3 cells expressing the EGFR^{Del19/T790M/C797S} mutant. One representative compound 6h time- and dose-dependently induced EGFR degradation with a DC₅₀ of 8 nM. It also showed good antiproliferation activity (IC₅₀ = 0.02μM) against Ba/F3-EGFR^{Del19/T790M/C797S} cells. 6h may serve as a lead compound to develop therapeutic agents for the treatment of resistant non-small cell lung cancer patients with EGFR C797S mutants.

Zhang, Jun;Zheng, Mengmeng;Yan, Jiayan;Deng, Zixin;Zhu, Dongqing;Qu, Xudong research published 《 A Permissive Medium Chain Acyl-CoA Carboxylase Enables the Efficient Biosynthesis of Extender Units for Engineering Polyketide Carbon Scaffolds》, the research content is summarized as follows. The selective incorporation of new-to-nature extender units into polyketide synthesis is a highly effective way to engineer their carbon scaffolds. Currently, most atypical extender units are biosynthesized via reductive carboxylation of α,β-unsaturated thioesters catalyzed by crotonyl-CoA reductase/carboxylases or thioesterification of malonates by malonyl-CoA ligases followed by epimerase catalyzed enantiomerization. In this study, we identified an unusual β-subunit (Arm13) of the acyl-CoA carboxylase (ACCase) from the biosynthesis of armeniaspirols. This β-subunit is permissive to the α- and ε-subunits of propionyl-CoA carboxylase to form a fully active ACCase. Distinct from the other regular ACCases in substrate specificity, this ACCase can directly carboxylate medium chain acyl-CoAs ranging from C6 to C9 either with or without terminal substituents, e.g., alkyne or Ph groups, to produce corresponding alkylmalonyl-CoAs with high catalytic efficiency. By harnessing the power of this ACCase in extender unit biosynthesis, we introduced structural variation into the carbon scaffold of armeniaspirols by feeding corresponding carboxylate precursors. These findings not only enrich the knowledge of the medium chain-specific ACCases but also provide an important biocatalyst for diversifying building blocks, which will greatly facilitate polyketide engineering.

Merging thermally activated delayed fluorescence (TADF) and mechanochromic luminescence (MCL) into one single mol. is a promising strategy for developing multifunctional organic materials. Herein, a unique multifunctional mol. TPA-DQP, comprising a large π-conjugated diquinoxalino[2,3-a:2′,3′-c]phenazine (DQP) as the acceptor and triphenylamine (TPA) as the donor, is designed and synthesized. TPA-DQP possesses polymorphism, efficient TADF emission as well as MCL property with high-contrast in emission colors from 576 to 706 nm. Reversible crystal-to-crystal phase transitions in response to external stimuli such as vapor fuming and heating are realized on the basis of the two polymorphs of TPA-DQP. The distinct crystal-to-crystal phase transition is attributed ultimately to the change of packing arrangements and intermol. interactions of the two polymorphs under stimuli. Furthermore, TPA-DQP-based organic light emitting diode (OLED) device achieves external quantum efficiency as high as 18.3% at 676 nm, which represents the best performance for deep-red OLEDs based on MCL-active TADF emitters. This study reports a novel MCL-active TADF material that exhibits crystal-to-crystal phase transition and brings insight into the underlying relationship between mol. packing modes and the photoluminescent behavior.

Two Ru(II) complexes containing different substituents, [Ru(phen)2(7-CH3-dppz)]2+ (Ru1) and [Ru(phen)2(7-Br-dppz)]2+ (Ru2), have been synthesized in this study. The binding properties of Ru1 and Ru2 with the duplex RNA poly(U)•poly(A) (where “•” denotes the Watson – Crick base pairing) have been researched by biophys. techniques and viscosity measurements. Anal. of spectral titrations and viscosity measurements indicate that Ru1 and Ru2 bind to the duplex via intercalative, and the binding affinity of Ru1 with the duplex is remarkably higher than that of Ru2. Furthermore, fluorescence emission spectra demonstrates that although complexes Ru1 and Ru2 can act as mol. “light switches” for the duplex RNA, alters in fluorescence emission of Ru1 and Ru2 are prominent differences, and the effectiveness of Ru1 is more remarkable compared with that of Ru2. The melting experiments suggest that the duplex RNA stabilizing effects of Ru1 and Ru2 differ from each other, among them, complex Ru1 can obviously enhance the stability of the duplex RNA, while Ru2 has only a slightly stabilizing effect for the duplex RNA, indicating that Ru1 preferentially binds to RNA duplex over Ru2. The obtained results indicate that subtle modifications of the intercalative ligand of Ru(II) polypyridyl complex with either Me or bromide group have a significant effect on the duplex-binding discrimination.
