The formylated spirobyclic alcohol was computer modeled to be a mimetic of paclitaxel. In this model, the formyl group was used as a truncated paclitaxel side chain in order to reduce the computational work. Compound , carrying the paclitaxel side chain, was synthesized in six steps from optically active 1,3-diketone . Microtubule stabilization was not observed for , indicating that the model needs to be adjusted.

Prodrug-based nanoassemblies are promising platforms for cancer therapy. Prodrugs typically consist of three main components: drug modules, intelligent response modules, and modification modules. However, the available modification modules are usually hydrophobic aliphatic side chains, which affect the activation efficiency of the prodrugs.

Ovarian cancer is known to be a challenging disease to detect at an early stage and is a major cause of death among women. The current treatment for ovarian cancer typically involves a combination of surgery and the use of drugs such as platinum-based cytotoxic agents, anti-angiogenic drugs, etc. However, current treatment methods are not always effective in preventing the recurrence of ovarian cancer.

Background: Paclitaxel is a widely used anticancer drug for ovarian, lung, breast, and stomach cancers; however, its clinical use is often limited by the side effects of peripheral neuropathy. This study evaluated the effects of () extract and its active metabolite, α-cyperone, on paclitaxel-induced neuropathic pain.
Methods: The oral administration of extract at doses of 500 mg/kg and intraperitoneal administration of α-cyperone at doses of 480 and 800 μg/kg prevented both the development of cold and mechanical pain.

Article Synopsis
- The study investigated how different treatments (balloon angioplasty vs. drug-coated balloons) affect the changes in blood vessel tissues following arteriovenous fistula stenosis in pigs with chronic kidney disease.
- Significant differences in tissue composition were observed, with drug-coated balloons leading to lower neointimal growth and higher endothelial cell counts compared to standard angioplasty.
- The findings suggest that using drug-coated balloons may improve vessel healing and reduce complications over time, as shown by varied immune cell responses and tissue growth patterns.
Multimodal Therapeutic Exercises and Their Role in Mitigating Chemotherapy-Induced Peripheral Neuropathy: A Longitudinal Study on Patient Outcomes.

Introduction A common side effect post chemotherapy is chemotherapy-induced peripheral neuropathy (CIPN). The purpose of this study was to investigate the effect of a multimodal exercise program compared to standard physical therapy in treating CIPN symptoms and improving daily living skills. Aim The aim of this study was to evaluate the effect of multimodal therapeutic exercises and their role in mitigating CIPN symptoms on the neuropathy score and instrumental activities of daily living.
