Interestingly, the transcriptional regulator Nur77, a promising therapeutic target in cancer, has been recently identified as a crucial regulator of ferroptosis. However, no ferroptosis inducer targeting Nur77 has been reported currently. In this study, we built upon our prior research on Nur77 modulator 4-PQBH to design and synthesize four series of new compounds, with the objective of developing novel Nur77-mediated ferroptosis inducers. Among them, compound <strong>8f</strong> exhibited the most potency against the tested cancer cell lines, including human estrogen positive breast cancer and triple-negative breast cancer cell lines, while displaying lower toxicity towards human normal cell lines HaCaT and MCF-10A (IC₅₀ <em>&gt;</em> 50 μM). Furthermore, <strong>8f</strong> demonstrated superior Nur77-binding activity in comparison to the reference compound Csn-B, and it has the capacity to activate the Nur77-driven luciferase activity and increase the protein level of Nur77. Remarkably, <strong>8f</strong> induced an increase in the levels of reactive oxygen species (ROS), malondialdehyde (MDA), and lipid peroxidation, concurrently with a reduction in the expression of GPX4 protein, culminating in the induction of ferroptosis in a Nur77-dependent manner. <em>In vivo</em>, <strong>8f</strong> treatment has been observed to significantly suppress MCF7 xenograft tumor growth. Consequently, a novel ferroptosis inducer targeting Nur77 (<strong>8f</strong>) is first reported as a potent anti-EPBC agent, providing may serve as a promising lead for further drug development targeting Nur77-mediated ferroptosis.","PeriodicalId":314,"journal":{"name":"European Journal of Medicinal Chemistry","volume":"37 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143758719","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Inhibiting <em>α</em>-amylase enzyme is considered as one of the key strategies for controlling chronic hyperglycemia. Therefore, the current work focuses on design and discovery of a series of thioxothiazolidine derivatives (<strong>5a-u</strong> and <strong>6a-g</strong>) as selective <em>α</em>-amylase inhibitors. The target compounds were synthesized using the Knoevenagel condensation approach and evaluated for their <em>α</em>-amylase and <em>α</em>-glucosidase inhibitory activities. The <em>in vitro</em> assay results demonstrated that the tested thioxothiazolidine derivatives possess significantly high potency than the standard drug acarbose against <em>α</em>-amylase but were inactive against <em>α</em>-glucosidase. Among them, compound <strong>5r</strong> exhibited remarkable inhibitory potential depicting an IC₅₀ value of 0.71 ± 0.01 μM, significantly outperforming acarbose against <em>α</em>-amylase. <em>In vivo</em> results further demonstrated that the treatment of diabetic rats with compound <strong>5r</strong> led to a significant reduction in blood glucose level, indicating its effectiveness in managing hyperglycemia. Biochemical profiling of the treated rats revealed favorable outcomes, including improved urea, creatinine, ALT, AST, ALP, and HbA1C values. Furthermore, <em>in vivo</em> testing in diabetic rats also demonstrated that treatment with compound <strong>5r</strong> caused significant histopathological improvements in the kidney, liver and pancreas compared to acarbose. The Lineweaver-Burk plot analysis indicated that compound <strong>5r</strong> inhibits <em>α</em>-amylase through a mixed type of inhibition mechanism.

ADCs combine an antibody, a linker, and a payload to result in a targeted therapeutic that minimizes toxicity resulting from systemic drug exposure. This review explores the innovative application of ADC technology towards immunosuppressive therapeutics, primarily focusing on antibody-mediated delivery of glucocorticoids (GCs). Despite their potent anti-inflammatory effects, the clinical use of GCs is limited by adverse systemic effects including osteoporosis, high blood sugar, adrenal insufficiency, weight gain, and glaucoma. Therefore, targeted delivery via ADCs presents a promising strategy to enhance therapeutic efficacy while reducing toxicity. Herein, we review the current status of immune-suppressing ADC technology, starting with early investigations of CD163-targeted dexamethasone and moving to the design of ADCs employing next-generation ultra-potent GCs. Additionally, we will discuss the current status of anti-inflammatory ADCs that employ non-glucocorticoid immune-suppressive medications. Throughout, we will highlight preclinical and clinical data that serves to derisk and drive investment in this new therapeutic class. In parallel, we will focus on ADC design principles that illustrate the importance of careful selection of payload, linker, and conjugation technology in this emerging field.","PeriodicalId":314,"journal":{"name":"European Journal of Medicinal Chemistry","volume":"31 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143737123","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
