Over the last few decades, we have gained insight into how researchers attempted to modify some natural molecules to be utilized as prospective agents for cancer treatment. Many scientists synthesized new natural compounds by incorporating specific functional groups and metals that improved their antitumor activity while reducing undesirable side effects. In this investigation, we synthesized four novel structurally modified enones that differ in the functional groups attached to the carbonyl group of the enone system (methyl - E1; isopropyl - E2; isobutyl - E3; and cyclopropyl - E4) and explored their anticancer potential against human carcinoma of the colon HCT-116, the cervical HeLa, and normal lung cells MRC-5.

Heyde syndrome, marked by aortic stenosis, gastrointestinal bleeding from angiodysplasia, and acquired von Willebrand syndrome, is often underreported. Shear stress from a narrowed aortic valve degrades von Willebrand factor multimers, leading to angiodysplasia formation and von Willebrand factor deficiency. This case report aims to raise clinician awareness of Heyde syndrome, its complexity, and the need for a multidisciplinary approach.

Article Synopsis
  • A new cytokine called IL-41 is linked to several autoimmune diseases, including rheumatoid arthritis (RA), and this study seeks to evaluate its potential as a biomarker for RA treatment effectiveness and patient responses.
  • The research involves 189 patients from a Serbian rheumatology clinic, split into groups based on their treatment: methotrexate alone, methotrexate with TNF inhibitors, or the IL-6 inhibitor tocilizumab.
  • Results show that tocilizumab significantly lowers IL-41 levels and improves disease symptoms the most, while smoking is identified as a major predictor of higher IL-41 concentrations in RA patients.

This detailed review focuses on retroperitoneal undifferentiated pleomorphic sarcoma (UPS), a particularly aggressive soft-tissue sarcoma that poses unique diagnostic and therapeutic challenges due to its rarity and complex presentation. By documenting a new case of retroperitoneal UPS and conducting a comprehensive review of all known cases, this article aims to expand the existing body of knowledge on the epidemiology, molecular pathogenesis, and treatment strategies associated with this rare disease. The complexity of diagnosing UPS is emphasized given that it rarely occurs in the retroperitoneal space and its histological and molecular complexity often complicates its recognition.

Article Synopsis
  • Acute pancreatitis (AP) is an inflammatory condition that can cause systemic responses and organ dysfunction; this study examines the role of Galectin-3 in modulating immune responses in AP.
  • In experiments with mice, Galectin-3 deficiency led to reduced immune cell types (like CD3CD49 T and CD4 T helper cells) and altered cytokine production, indicating a shift toward a more anti-inflammatory response.
  • The findings suggest that Galectin-3 plays a significant role in acute pancreatitis and could be a potential target for new treatments aimed at managing inflammatory diseases of the pancreas.

Metformin, a medication known for its anti-glycemic properties, also demonstrates potent immune system activation. In our study, using a 4T1 breast cancer model in BALB/C WT mice, we examined metformin's impact on the functional phenotype of multiple immune cells, with a specific emphasis on natural killer T (NKT) cells due to their understudied role in this context. Metformin administration delayed the appearance and growth of carcinoma.

In order to discover new anticancer drugs, novel ruthenium(III) complexes [Ru(L)Cl(HO)], where L is tetradentate Schiff base bis(acetylacetone)ethylendiimine (acacen, 1), bis(benzoylacetone)ethylendiimine (bzacen, 2), (acetylacetone)(benzoylaceton)ethylendiimine (acacbzacen, 3), bis(acetylacetone)propylendiimine (acacpn, 4), bis(benzoylacetone)propylendiimine (bzacpn, 5) or (acetylacetone)(benzoylaceton)propylendiimine (acacbzacpn, 6), were synthesized. The complexes 1 - 6 were characterized by elemental analysis, molar conductometry, and by various spectroscopic techniques, such as UV-Vis, IR, EPR, and ESI-MS. Based on in vitro DNA/BSA experiments, complexes 2 (bzacen) and 5 (bzacpn) with two aromatic rings showed the highest DNA/BSA-activity, suggesting that the presence of the aromatic ring on the tetradentate Schiff base ligand contributes to increased activity.
