The effect of imides, monothioimides, trimellitimides, as well as 5'-deoxy-5'-phthaloylamino-derivatives of azidothymidine on tumor necrosis factor-alpha (TNF-alpha) production by genetically modified murine B78H1 melanoma cells transduced with the gene for human TNF-alpha (B78/TNF) was investigated. It was found that N-(adamant-1-yl)monothiophthalimide (1e) and N-(adamant-2-yl)-monothiophthalimide (1f) showed over 200% enhancing of TNF-alpha production while some of imides were inhibitors.

Risk of Cancers According to the Use of Biological Agents in Patients With Radiographic Axial Spondyloarthritis: A Nationwide Population-Based Cohort Study.
J Clin Rheumatol
January 2025
From the Division of Rheumatology, Department of Internal Medicine, Yonsei University College of Medicine, Seoul, South Korea.
Objective: As the duration of use of biological disease-modifying antirheumatic drugs (bDMARDs) in patients with radiographic axial spondyloarthritis (r-axSpA) accumulates over time, long-term real-world safety data on cancer risk are needed. This study assessed the association between tumor necrosis factor inhibitors (TNFis) and interleukin 17 inhibitors (IL-17is) exposures and cancer risk in patients with r-axSpA.
Methods: From the Korean nationwide database, we assembled 41,889 patients without prior history of cancer who were diagnosed with r-axSpA from 2010 onwards.
Antioxidant and anti-inflammatory function of walnut green husk aqueous extract (WNGH-AE) on human hepatocellular carcinoma cells (HepG2) treated with t-BHP.

Oxidative damage, oxidative inflammation, and a range of downstream diseases represent significant threats to human health. The application of natural antioxidants and anti-inflammatory agents can help prevent and mitigate these associated diseases. In this study, we aimed to investigate the effectiveness of walnut green husk (WNGH) as an antioxidant and anti-inflammatory agent in an in vitro setting.

A number of studies demonstrate the therapeutic effectiveness of Radix Bupleuri (RB) and Hedysarum Multijugum Maxim (HMM) in treating liver fibrosis, but the exact molecular mechanisms remain unclear. This study aims to explore the mechanism of RB-HMM drug pairs in treating liver fibrosis by using network pharmacology, bioinformatics, molecular docking, molecular dynamics simulation technology and in vitro experiments. Totally, 155 intersection targets between RB-HMM and liver fibrosis were identified.

Introduction: Ozoralizumab (OZR) is a novel tumor necrosis factor (TNF) inhibitor that was launched in Japan for treating patients with rheumatoid arthritis (RA) who have had an inadequate response to existing therapies. This post-hoc analysis aimed to compare the efficacy of OZR administered without methotrexate (MTX) with placebo or OZR administration in combination with MTX.
Methods: We analyzed the OZR group (30 mg) in the NATSUZORA trial (non-MTX, open trial) (OZR group; n = 94) and the placebo group (MTX group; n = 75) and the 30-mg OZR group (OZR + MTX group; n = 152) in the OHZORA trial (combined MTX, double-blind trial), and the covariates were adjusted by propensity score matching.
