Cancer and antibiotic-resistant bacterial infections are significant global health challenges. The resistance developed in cancer treatments intensifies therapeutic difficulties. In addressing these challenges, this study synthesised a series of N,N'-dialkyl urea derivatives containing methoxy substituents on phenethylamines.

Article Synopsis
  • Multiple myeloma (MM) is a type of cancer affecting plasma cells in the bone marrow, characterized by altered metabolism, particularly in glycolysis, lipid metabolism, and mitochondrial respiration.
  • Recent advancements in technology, like the Seahorse™ XF analyzer, allow researchers to monitor real-time changes in cell metabolism, specifically glycolytic flux and mitochondrial activity, in various cell types, though non-adherent suspension cells present challenges.
  • The authors present an optimized protocol for analyzing live myeloma cells under drug treatment using the XF analyzer, demonstrating that their method yields consistent results, which could be beneficial for future research on metabolic processes in similar cells.

Article Synopsis
  • Aerobic glycolysis is crucial for cancer cell proliferation, providing energy and building blocks for growth through the M2 isoform of pyruvate kinase (PKM2).
  • PKM2 is vital in the glycolytic pathway, transferring phosphate to ADP to produce ATP and pyruvate, with its activity regulated by various mechanisms involving oncogenes and tumor suppressor genes.
  • An in vitro kinase assay was developed to study PKM2 phosphorylation by JNK, aiding in understanding kinase-substrate interactions and allowing for the measurement of phosphorylation without radioactive materials.

Hesperidin is a prominent flavanone found in citrus fruits that has a broad range of biological effects, including anti-inflammatory and antioxidant capabilities. The study's objective was to evaluate the effects of hesperidin supplementation on anti-inflammatory and antioxidant parameters such as MDA, TAC, GSH, SOD, and CAT; CRP, TNF-α, IL-6, and IL-4 levels respectively, by analyzing human intervention trials. Google Scholar, PubMed, grey literature databases, and the ClinicalTrials website were scanned to identify eligible studies.

Stachys species belonging to Lamiaceae family have been used for medicinal purposes since ancient times. The aim of the present study was to investigate the chemical compositions and antibacterial, anti-tyrosinase activities of the essential oil of Stachys macrostachya. The essential oil was prepared by hydrodistillation method using a Clevenger-type apparatus and chemical composition was determined by gas chromatography (GC).

In cancer treatments, many natural and synthetic products have been examined; among them, protease inhibitors are promising candidates for anti-cancer agents. Since dysregulated proteolytic activities can contribute to tumor development and metastasis, antagonization of proteases with tailored inhibitors is an encouraging approach. Although adverse effects of early designs of these inhibitors disappeared after the introduction of next-generation agents, most of the proposed inhibitors did not pass the early stages of clinical trials due to their nonspecific toxicity and lack of pharmacological effects.

Background: In this study, we aimed to determine synergistic apoptotic and cytotoxic effects of methylstat and bortezomib on U266 and ARH77 multiple myeloma (MM) cells.

Methods: Cytotoxic effects of the drugs were demonstrated by MTT cell proliferation assay while apoptotic effects were examined by loss of mitochondrial membrane potential (MMP) by JC-1 MMP detection kit, changes in caspase-3 enzyme activity and Annexin-V apoptosis assay by flow cytometry. Expression levels of apoptotic and antiapoptotic genes were examined by qRT-PCR.

Chemotherapy frequently involves combination treatment protocols to maximize tumor cell killing. Unfortunately these intensive chemotherapeutic regimes, often show disappointing results due to the development of drug resistance and higher nonspecific toxicity on normal tissues. In cancer treatment, it is critically important to minimize toxicity while preserving efficacy.
