We recently described several highly potent, triazine (1) and triazolopyrimidine (2) scaffold-based, dual PI3K/mTOR-inhibitors (e.g., 1, PKI-587) that were efficacious in both in vitro and in vivo models. In order to further optimize these compounds we devised a novel series, the 2-oxatriazines, which also exhibited excellent potency and good metabolic stability. Some 2-oxatriazines showed promising in vivo biomarker suppression and induced apoptosis in the MDA-MB-361 breast cancer xenograft model.

Controlling microbial pollutants is a significant public health concern as they cause several chronic microbial infections and illnesses. In recent years, essential oils (EOs) have become intriguing alternatives for synthetic antimicrobials due to their biodegradability, natural source extraction, and strong antibacterial properties. The bactericidal properties of alginate containing lemon essential oil were examined in this investigation.

Background: Dermatomyositis is a chronic autoimmune disease with distinctive cutaneous eruptions and muscle weakness, and the pathophysiology is characterised by type I interferon (IFN) dysregulation. This study aims to assess the efficacy, safety, and target engagement of dazukibart, a potent, selective, humanised IgG1 neutralising monoclonal antibody directed against IFNβ, in adults with moderate-to-severe dermatomyositis.
Methods: This multicentre, double-blind, randomised, placebo-controlled, phase 2 trial was conducted at 25 university-based hospitals and outpatient sites in Germany, Hungary, Poland, Spain, and the USA.

Dermal papilla cells (DPCs) are a crucial subset of mesenchymal cells in the skin responsible for regulating hair follicle development and growth, making them invaluable for cell-based therapies targeting hair loss. However, obtaining sufficient DPCs with potent hair-inducing abilities remains a persistent challenge. In this study, the Food and Drug Administration (FDA)-approved drug library was utilized to screen small molecules capable of reprogramming readily accessible human skin fibroblasts into functional DPCs.

The emergence of New Delhi metallo-β-lactamase-1 (NDM-1) poses a significant threat to the clinical application of antibiotics, as it possesses the ability to hydrolyze nearly all β-lactam antibiotics. Regrettably, there are currently no clinical drugs targeting NDM-1, making it imperative to develop highly potent and minimally toxic NDM-1 inhibitors. Herein, a series of molecular Trojan horses targeting NDM-1 were synthesized by introducing ebselen into 7-aminocephalosporanic acid derivatives via a C-Se bond.

Article Synopsis
- Drug resistance in cancer is increasing, highlighting the need for new therapeutic targets, particularly through ion interference strategies involving calcium ions (Ca).
- The study investigates the link between calcium ions and ferroptosis (iron-induced cell death), suggesting that disrupted calcium balance could lead to increased ferroptosis in cancer cells, providing a novel treatment target.
- Findings indicate that Ca modulates ferroptosis by affecting reactive oxygen species (ROS) and glutathione (GSH) levels in various cancer and normal cells, with potential applications for plant-derived compounds as effective anticancer treatments.
