Ma, Junfu; Meng, Qingliang; Zhan, Junping; Wang, Huilian; Fan, Wei; Wang, Yanqi; Zhang, Sudan; Bian, Hua; Zheng, Fuzeng published the artcile< Paeoniflorin Suppresses Rheumatoid Arthritis Development via Modulating the Circ-FAM120A/miR-671-5p/MDM4 Axis>, Reference of 112-63-0, the main research area is paeoniflorin AMA microRNA MDM rheumatoid arthritis development; Circ-FAM120A; Paeoniflorin; Rheumatoid arthritis; mDM4; miR-671-5p.

Paeoniflorin is an active ingredient derived from Paeonia, which has an anti-inflammatory effect. However, the potential role and basis of paeoniflorin in rheumatoid arthritis (RA) are indistinct. Cell viability, cycle distribution, migration, and invasion were evaluated via Cell Counting Kit-8 (CCK-8), flow cytometry, and transwell assays. The contents of inflammatory cytokines were examined using ELISA (ELISA). RNA expression levels were determined via qRT-PCR and western blot. The targeting relationship between miR-671-5p and circ-FAM120A (hsa_circ_0003972) or murine double minute 4 (MDM4) was validated via dual-luciferase reporter assay. Paeoniflorin restrained proliferation, migration, invasion, and inflammation and accelerated cell cycle arrest in RA fibroblast-like synoviocytes (RA-FLSs). Circ-FAM120A was boosted in RA synovial tissues and RA-FLSs. Circ-FAM120A upregulation, miR-671-5p knockdown, or MDM4 augmentation reversed the repressive effect of paeoniflorin on RA-FLS progression. Moreover, paeoniflorin attenuated RA-FLS progression by regulating the circ-FAM120A/miR-671-5p/MDM4 axis. Paeoniflorin inhibited RA-FLS proliferation, mobility, and inflammation and triggered cell cycle arrest via mediating the circ-FAM120A/miR-671-5p/MDM4 pathway.

Yan, Guoyi; Pu, Chunlan; Lan, Suke; Zhong, Xinxin; Zhou, Meng; Hou, Xueyan; Yang, Jie; Shan, Huifang; Zhao, Lifeng; Li, Rui published the artcile< Discovery of 4-phenyl-2H-benzo[b][1,4]oxazin-3(4H)-one derivatives as potent and orally active PI3K/mTOR dual inhibitors>, Quality Control of 112-63-0, the main research area is benzooxazinone preparation SAR PI3K mTOR dual inhibitor antitumor human; Cancer treatment; Dual inhibitor; PI3K/mTOR; Structural optimization.

PI3K/Akt/mTOR signaling pathway plays an important role in cancer cell growth and survival. In this study, a new class of mols. with skeleton of 4-phenyl-2H-benzo[b][1,4]oxazin-3(4H)-one I (X = H, F, Cl, etc.; R1 = 4-HOC6H4, 3-quinoline, 3-(4-fluoro-benzenesulfonamido)phenyl, etc.) II (R = i-Pr, cyclopropyl, Cy; R1 = 4-HOC6H4, 3-quinoline, 3-(4-fluoro-benzenesulfonamido)phenyl, etc.) were designed and synthesized targeting this pathway. Bioassays showed that, among all the mols., I (X = 4-OMe; R1 = 2-methoxy-3-(4-fluoro-benzenesulfonamido)pyrid-5-yl) was a pan-class I PI3K/mTOR inhibitor with an IC50 of 0.63 nM against PI3Kα. In a wide panel of protein kinases assays, no off-target interactions of I (X = 4-OMe; R1 = 2-methoxy-3-(4-fluoro-benzenesulfonamido)pyrid-5-yl) were identified. I (X = 4-OMe; R1 = 2-methoxy-3-(4-fluoro-benzenesulfonamido)pyrid-5-yl) was orally available, and displayed favorable pharmacokinetic parameters in mice (oral bioavailability of 24.1%). In addition, I (X = 4-OMe; R1 = 2-methoxy-3-(4-fluoro-benzenesulfonamido)pyrid-5-yl) demonstrated significant efficiency in Hela/A549 tumor xenograft models (TGI of 87.7% at dose of 50 mg/kg in Hela model) without causing significant weight loss and toxicity during 30 days treatment. Based on the bioassays, compound I (X = 4-OMe; R1 = 2-methoxy-3-(4-fluoro-benzenesulfonamido)pyrid-5-yl) could be used as an anti-cancer drug candidate.

Drug-induced uveitis is a rare but sight-threatening condition. We seek to determine the spectrum of drug-induced uveitis at the era of immune checkpoint inhibitors (ICI). Retrospective pharmacovigilance study based on adverse drug reactions reported within VigiBase, the WHO international pharmacovigilance database. We included deduplicated individual case safety reports (ICSRs) reported as ‘uveitis’ at Preferred Term level according to the Medical Dictionary for Drug Regulatory Activities between 1967 and 04/28/2019. We performed a case/non-case anal. to study if suspected drug-induced uveitis were differentially reported for each suspected treatment compared to the full database. We excluded drugs with potential indication bias.1404 ICSRs corresponding to 37 drugs had a significant over-reporting signal with a median age of 57 [42-68] years and 45.7% of males. We identified five major groups of treatments: bisphosphonates (26.9%), non-antiviral anti-infectious drugs (25.4%), protein kinase inhibitors (15.5%), ICI (15.0%), and antiviral drugs (11.1%). Severe visual loss was reported in 12.1% of cases. ICI and protein kinase inhibitors were the most recently emerging signals. The time to onset between first infusion and uveitis was significantly different between groups ranging from 5 days [2-19] in the bisphosphonate group to 138.5 [47.25-263.75] in protein kinase inhibitors group (p < 0.0001). Anti-Programmed Cell death 1 represented more than 70% of ICI-induced uveitis. We identified Vogt-Koyanagi-Harada (VKH)-like syndrome as being associated with ICI use. The spectrum of drug-induced uveitis has changed with the evolution of pharmacopeia and the recent emergence of ICIs. VKH-like syndrome has been reported with ICI and protein kinase inhibitors therapy.

He, Lu; Huang, Jun; Chen, Yuhui published the artcile< First-Order or Second-Order? Disproportionation of Lithium Superoxide in Li-O2 Batteries>, Name: (9Z,12Z)-Methyl octadeca-9,12-dienoate, the main research area is lithium superoxide battery.

The disproportionation of LiO2 to Li2O2 is a key step in Li-O2 batteries, and it is regarded as a second-order reaction. However, its mechanism is not well addressed, and its kinetics is rarely studied due to the difficulties of quantifying the rate constants, particularly for high concentrations of superoxide (>10 mM). Here, we quantified the kinetic rate constant by a microkinetic model using a microelectrode tip with a thin diffusion layer and fast response. We report that the reaction order of LiO2 transitions from 1 at high concentrations of superoxide (~20 mM) to 2 at low concentrations of superoxide (~1 mM). LiO2 is chem. reduced by free superoxides to form Li2O2 and O2, instead of reacting with another LiO2 via a disproportionation step. This chem.-reduction mechanism explained the change of reaction order and the kinetics profile. As a rate-determining step, this step restricts the overall kinetics of the discharging process and should be the focus of future catalyst design.
