Ma, Xiaojun;Sun, Nannan;Li, Xinwei;Fu, Wei research published 《 Discovery of novel N-sulfonamide-tetrahydroisoquinolines as potent retinoic acid receptor-related orphan receptor γt agonists》, the research content is summarized as follows. Cancer immunotherapy has become a research hotspot in recent years. A variety of targets were developed for small mol. immuno-oncol. agents, including retinoic acid-related orphan receptor gamma t (RORγt), chemokine receptor, stimulator of interferon genes (Sting), indoleamine 2,3-dioxygenase (IDO), toll-like receptors (TLR), etc. Among them, the retinoic acid receptor-related orphan receptor γt (RORγt) has gradually attracted more attention in these years. In particular, LYC-55716 (cintirorgon), a small mol. RORγt agonist developed by Lycera, has entered the phase II clin. study. In this work, starting from compound 7, compound 28 was obtained after 4 rounds of compound design, synthesis and SAR studies, which had an EC50 of 0.021 ± 0.002 μM in dual Fluorescence Resonance Energy Transfer (dual-FRET) assay and an EC50 of 0.021 ± 0.002 μM in mouse Th17 cell differentiation assay. It indicated that compound 28 had excellent RORγt agonistic activity and was expected to be developed as a new type of small mol. drug for cancer immunotherapy. The mol. dynamic simulation revealed that the agonist 28 formed a strong HYF triplet intramol. interaction to stabilize H12, which helped RORγt to form the protein-binding site and therefore made the receptor ready to recruit coactivator. When the inverse agonist s27 bound with RORγt, the steric hindrance between s27 and H479 caused the destruction of the HYF triplet, leading to the collapse of H12, thus the transcription function of RORγt was interrupted due to the failure of recruiting a coactivator mol. The triplet HYF in RORγt and the rigidity of 28 and s27 were identified to be the structural determinants for the functional switch of RORγt.

Maegawa, Koshiro;Tanimoto, Hiroki;Onishi, Seiji;Tomohiro, Takenori;Morimoto, Tsumoru;Kakiuchi, Kiyomi research published 《 Taming the reactivity of alkyl azides by intramolecular hydrogen bonding: site-selective conjugation of unhindered diazides》, the research content is summarized as follows. Organic azides are still in the center of click chem. connecting two mols. However, taming the conjugation selectivity of azides is difficult without the help of bulky groups. Herein the unique reactivities of α-azido secondary acetamides (α-AzSAs) as minimal and unhindered azide structures is reported. The NH-azide interaction in the α-AzSAs, supposed by DFT calculations, allowed selective conjugation in the presence of other azido moieties, even without steric hindrance. With Staudinger-Bertozzi ligation, α-AzSAs underwent conjugation prior to the other primary alkyl azides. On the other hand, in propargyl cation-mediated triazole synthesis, other alkyl azides, including tertiary alkyl azides, underwent the conjugation faster than α-AzSAs. Authors also demonstrated site-selective integration of the functional components onto the diazide modular hubs.

Liu, Jiawei;Li, Lin;Xu, Zhongzheng;Chen, Jia;Zhao, Mingwei;Dai, Caili research published 《 CO₂-responsive zwitterionic copolymer for effective emulsification and facile demulsification of crude heavy oil》, the research content is summarized as follows. Viscosity reduction by emulsification would greatly facilitate the exploitation and pipelining transportation of heavy oil, as well as oil sands/sludge washing. However, the final demulsification process to achieve separation of oil and water is tricky. Therefore, developing smart emulsifiers that can be switched on demand to achieve both effective emulsification and facile demulsification in subsequent oil/water separation process would be of great significance to the practical applications. In this paper, a zwitterionic copolymer emulsifier comprising acrylamide (AM), 2-(diethylamino)ethyl methacrylate (DEAEMA) and 3-[dimethyl-[2-(2-methylprop-2-enoyloxy)ethyl]azaniumyl]propane-1-sulfonate (SBMA) was prepared via reversible addition-fragmentation chain transfer (RAFT) polymerization for better control of the mol. weight, exhibiting good salt resistance and fast CO2-responsiveness. The prepared copolymer can efficiently emulsify heavy crude oil with a viscosity reduction rate up to 98.6% in highly mineralized water. While in the presence of CO₂, the formed heavy oil/water emulsions can be rapidly broken to obtain oil-water two phases. Compared with traditional demulsification methods, the CO₂-responsive strategy presented in this work can achieve a lower oil content in water (1.4%) after separation Furthermore, the copolymer can also be applied to effectively emulsify and clean oily sludge. The CO₂-responsive zwitterionic copolymer emulsifier demonstrated great potential in various engineering applications including exploitation and pipelining transportation of heavy oil, and oil sands/sludge washing, facilitating reduction of water pollution and energy saving.
