Meden, Anze;Knez, Damijan;Malikowska-Racia, Natalia;Brazzolotto, Xavier;Nachon, Florian;Svete, Jurij;Salat, Kinga;Groselj, Uros;Gobec, Stanislav research published 《 Structure-activity relationship study of tryptophan-based butyrylcholinesterase inhibitors》, the research content is summarized as follows. A series of tryptophan-based selective nanomolar butyrylcholinesterase (BChE) inhibitors was designed and synthesized. Compounds were optimized in terms of potency, selectivity, and synthetic accessibility. The crystal structure of the inhibitor (I) in complex with BChE revealed the mol. basis for its low nanomolar inhibition (IC₅₀ = 2.8 nM). The favorable in vitro results enabled a first-in-animal in vivo efficacy and safety trial, which demonstrated a pos. impact on fear-motivated and spatial long-term memory retrieval without any concomitant adverse motor effects. Altogether, this research culminated in a handful of new lead compounds with promising potential for symptomatic treatment of patients with Alzheimer’s disease.

Mao, Runze;Bera, Srikrishna;Turla, Aurelya Christelle;Hu, Xile research published 《 Copper-Catalyzed Intermolecular Functionalization of Unactivated C(sp³)-H Bonds and Aliphatic Carboxylic Acids》, the research content is summarized as follows. A Cu-catalyzed process for the diverse functionalization of both unactivated C(sp³)-H bonds RH (cyclododecyl, n-hexyl, tetrahydrofuran-2-yl, etc.) and aliphatic carboxylic acids R¹C(O)OH (R¹ = 1-phenylethyl, tetrahydro-2H-pyran-4-yl, 4-oxocyclohexyl, etc.) was described. The process is enabled by trapping of alkyl radicals generated through hydrogen atom abstraction by arylsulfonyl-based SOMO-philes, which introduces a large array of C, N, S, Se, and halide-based functional groups. The chemoselectivity can be switched from C-H functionalization to decarboxylative functionalization by matching the bond dissociation energy of the hydrogen atom transfer reagent with that of the target C-H or O-H bond.

Malamas, Michael S.;Lamani, Manjunath;Farah, Shrouq I.;Mohammad, Khadijah A.;Miyabe, Christina Yume;Rajarshi, Girija;Wu, Simiao;Zvonok, Nikolai;Chandrashekhar, Honrao;Wood, JodiAnne;Makriyannis, Alexandros research published 《 Design and Synthesis of Highly Potent and Specific ABHD6 Inhibitors》, the research content is summarized as follows. Fine-tuning than complete disruption of 2-arachidonoylglycerol (2-AG) metabolism in the brain represents a promising pharmacol. approach to limit potential untoward effects associated with complete blockade of monoacylglycerol lipase (MGL), the primary hydrolase of 2-AG. This could be achieved through a/b-hydrolase domain containing 6 (ABHD6) inhibition, which will provide a smaller and safer contribution to 2-AG regulation in the brain. Pharmacol. studies with ABHD6 inhibitors have recently been reported, where modulation of ABHD6 activity either through CB1R-dependent or CB1R-independent processes showed promise in preclin. models of epilepsy, neuropathic pain and inflammation. Furthermore in the periphery, ABHD6 modulates 2-AG and other fatty acid monoacylglycerols (MAGs) and is implicated in Type-2 diabetes, metabolic syndrome and potentially other diseases. Herein, we report the discovery of single-digit nanomolar potent and highly specific ABHD6 inhibitors with >1000-fold selectivity against MGL and FAAH. The new ABHD6 inhibitors provide early leads to develop therapeutics for neuroprotection and the treatment of inflammation and diabetes.

Ma, Jianchao;Zhang, Siyu;Duan, Xiaoguang;Wang, Yuxin;Wu, Danlei;Pang, Jin;Wang, Xin;Wang, Shaobin research published 《 Catalytic oxidation of sulfachloropyridazine by MnO₂: Effects of crystalline phase and peroxide oxidants》, the research content is summarized as follows. Catalytic activation of different oxidants including peroxymonosulfate (PMS), peroxydisulfate (PDS), hydrogen peroxide (H₂O₂) and ozone (O₃) by MnO₂ for degradation of sulfachloropyridazine (SCP) was investigated and the effects of different crystalline phases of MnO₂ including nanowire α-MnO₂, nanorod β-MnO₂, nanofiber γ-MnO₂, and nanosphere δ-MnO₂ on catalytic ozonation of SCP were also studied. The SCP degradation and total organic carbon removal indicated that the oxidation efficiency of the peroxide oxidants followed an order of O3/MnO₂ > PMS/MnO₂ > PDS/MnO₂ > H₂O₂/MnO₂. In catalytic ozonation, SCP degradation rate constants of different MnO₂ phases followed an order of δ-MnO₂ > α-MnO₂ > γ-MnO₂> β-MnO₂. ESR (EPR) suggested that hydroxyl radicals (·OH) and singlet oxygen (¹O₂) might be more significant for SCP degradation than sulfate (SO·^–₄) and superoxide (·O^–₂) radicals. Radical competition experiments demonstrated that ¹O₂ and ·OH contributed to 63.16% and 28.07%, resp., for the catalytic ozonation of SCP. It was also found that more oxygen vacancies, sp. surface area and exposure of MnO₆ edges could facilitate the activation of O₃ for ¹O₂ and ·OH productions and SCP degradation The degradation pathways of SCP could mainly follow the cleavage of S-C or S-N bond and dechlorination, accompanied by hydroxylation and oxidation

Ma, Huijun;Qian, Anran;Zheng, Yazhou;Meng, Xin;Wang, Ting;Zhang, Yinyong;Sun, Lulu;Zou, Feng;Zhao, Bomei;Zhang, Shuhua;Zhang, Dan;Yang, Yushe research published 《 Design, Synthesis, and Structure-Activity Relationship Studies of Bisamide Derivatives of Amphotericin B with Potent Efficacy and Low Toxicity》, the research content is summarized as follows. Amphotericin B (AMB, 1) is the most powerful antibiotic in treating potentially life-threatening invasive fungal infections (IFIs), though severe toxicity derived from self-aggregation greatly limits its clin. application. Herein, we applied a bisamidation strategy at the C16-COOH and C3′-NH₂ to improve the therapeutic properties by suppressing self-aggregation. It was found that basic amino groups at the residue of C16 amide were beneficial to activity, while lipophilic fragments contributed to toxicity reduction Addnl., N-methyl-amino acetyl and amino acetyl moieties at C3′ amide could help keep the fungistatic effectiveness. The modification work culminated in the discovery of 36 (I) (ED₅₀ = 0.21 mg/kg), which exerted a 1.5-fold stronger antifungal efficacy than amphamide, the optimal derivative theretofore, in mice, low self-aggregation propensity, and thus low acute toxicity. With the improvement in therapeutic index and good PK profile, 36 is promising for further development as a second-generation polyene antifungal agent.

Luo, Tao;Peng, Ying;Chen, Long;Li, Jinjun;Wu, Feng;Zhou, Danna research published 《 Metal-free electro-activated sulfite process for As(III) oxidation in water using graphite electrodes》, the research content is summarized as follows. Transition-metal-activated sulfite [S(IV)] processes for water decontamination have recently received intense attention in the field of decontamination by advanced oxidation processes (AOPs). However, the drawback with respect to the secondary metal sludge contamination involved in various AOPs has been argued often. In this work, we developed a novel electro-sulfite (ES) process using stable and low-cost graphite electrodes to address that concern. Arsenite [As(III)] was used as the target compound for removal by the ES process because of its wide presence and high toxicity. Parameters, including cell voltage, S(IV) concentration, solution pH, and water matrix, and the mechanisms for reactions on anode and cathode were investigated in electrolytic cells containing one or two compartments, resp. The results show that the ES process using 1 mM S(IV) and 2 V cell voltage oxidizes 5μM As(III) at a rate of 0.127 min^-1, which is 15-fold higher than mere electrolysis without S(IV) addition (0.008 min^-1) at pH 7. Further studies using radical scavengers and ESR assays demonstrated that oxysulfur radicals (i.e., SO₅^•- and SO₄^•-) and HO^• are responsible for As(III) oxidation in the ES process. However, HO₂^• produced via the oxygen reduction reaction in the EO process plays a major role in As(III) oxidation, which explains the lower reaction rate in the absence of S(IV). The effectiveness of the ES process was moreover evidenced by 60-82% As(III) oxidation in field water within 40 min. Overall, this work realizes the metal-free activation of S(IV) and significantly leverages the S(IV)-based water treatment technologies.

Luo, Haopeng;Zhou, Xin;Chen, Quanyuan;Zhou, Juan research published 《 Removal of 2,4-dichlorophenoxyacetic acid by the boron-nitrogen co-doped carbon nanotubes: Insights into peroxymonosulfate adsorption and activation》, the research content is summarized as follows. B, N co-doped CNTs were synthesized by a simple one-step thermal process and the advanced oxidation processes (AOPs) of 2,4-dichlorophenoxyacetic acid (2,4-D) over the catalyst involved peroxymonosulfate (PMS) activation was investigated. The co-doped catalysts showed higher isoelec. points (IEPs) than those of CNTs and single doped CNTs, facilitating the adsorption of PMS anion (HSO-5) on the catalyst surface, and the AOPs of 2,4-D depended on PMS concentration could be illustrated by the Langmuir-Hinshelwood model. The removal efficiency of 2,4-D over CNTs, CB450, CN450 and CBN450-2 was 20%, 23%, 34% and 68%, resp. The enhancement of catalytic activity was due to the synergistic effect between B and N dopants and both the pyrrolic N and B-N complex played roles in the catalytic reaction. The quenching test and ESR (EPR) results showed that 1O₂ contributed most to the oxidation of 2,4-D and the reaction experienced both the free radical and non-radical pathways. Addnl., the DFT calculation results showed that the adsorption energy of PMS on the surface N dopants decreased by B co-doping, implying that a moderate adsorption energy may facilitate the release of active species generated by PMS activation.
