Marine algae are abundant and inexhaustive sources of the bioactive compounds with the various benefits for human health. Among these substances an attention is given to the sulfated polysaccharides presented as the complexes of polymer macromolecules with excellent biological features including antioxidant, anti-inflammatory anticoagulant, antiviral, and immunomodulatory activities. In addition to the aforementioned properties there is a growing number of research results suggesting the bioactive sulfated polysaccharides such as carrageenan, fucoidan, laminarin, and others exert anticancer and antimetastatic properties. The present review contains the main results of experimental studies of the carrageenan anticancer activity including systemic and intracellular mechanisms of the antiproliferative influence. Relationships between structure, physico-chemical properties of carrageenan and their antitumor effects are described. There are data on the toxicology and pharmacokinetics of carrageenans as well as other aspects of their pharmacotherapeutic and pharmacoprophylactic influence that allow considering them as the potential anticancer agents.

Purpose: The main purpose of the study was the formulation development of nanogels (NHs) composed of chondroitin sulfate (CS) and low molecular weight chitosan (lCH), loaded with a naringenin-β-cyclodextrin complex (NAR/β-CD), as a potential treatment for early-stage diabetic retinopathy.

Methods: Different formulations of NHs were prepared by varying polymer concentration, lCH ratio, and pH and, then, characterized for particle size, zeta potential, particle concentration (particles/mL) and morphology. Cytotoxicity and internalization were assessed in vitro using Human Umbilical Vein Endothelial Cells (HUVEC).

Combined blockade of the immune checkpoints PD-1 and CTLA-4 has shown remarkable efficacy in patients with melanoma, renal cell carcinoma, non-small-cell lung cancer and mesothelioma, among other tumor types. However, a proportion of patients suffer from serious immune-related adverse events (irAEs). In severe cases, a reduction of the doses or the complete cessation of the treatment is required, limiting the antitumor efficacy of these treatments.

Background/objectives: Ulcerative colitis (UC) is a chronic and easily recurrent inflammatory bowel disease. The gut microbiota and plasma metabolites play pivotal roles in the development and progression of UC. Therefore, therapeutic strategies targeting the intestinal flora or plasma metabolites offer promising avenues for the treatment of UC.

Osteoarthritis (OA) is a chronic disease characterized by cartilage degradation, leading to bone friction, inflammation, stiffness, pain, and reduced mobility. This study investigates the therapeutic effects of porcine-derived chondroitin sulfate sodium (CS) on OA symptoms at both cellular and animal levels. study, HTB-94 chondrocytes were treated with inflammatory stimuli and CS (10, 50, 100, and 200 μg/mL) to assess the release of inflammatory mediators and the expression of genes and proteins related to cartilage synthesis and degradation.
