The history of effective anti-cancer medications begins with the discovery of cisplatin’s anti-cancer properties. Second-generation analogue, carboplatin, with a similar range of effectiveness, made progress in improving these drugs with fewer side effects and better solubility. Renewed interest in platinum-based drugs has been increasing in the past several years. These developments highlight a revitalized enthusiasm and ongoing exploration in platinum chemotherapy based on the series of dinuclear platinum(II) complexes, [{Pt(L)Cl}₂(μ-bridging ligand)]²⁺, which have been synthesized and evaluated for their biological activities. These complexes are designed to target various cancerous conditions, exhibiting promising antitumor, antiproliferative, and apoptosis-inducing activities. The current work aims to shed light on the potential of these complexes as next-generation platinum-based therapies, highlighting their enhanced efficacy and reduced side effects, which could revolutionize the approach to chemotherapy.

Myocarditis is still a major global health issue that frequently manifests due to oxidative stress, immune-mediated myocardial damage, and unpredictable clinical progression. Experiments with autoimmune myocarditis (EAM) models have shown different ways that T-cell subsets, proinflammatory cytokines, macrophage polarization, and mitochondrial dysfunction are all connected and play a part in both acute inflammation and chronic remodeling of the heart. As a possible multimodal intervention that could affect several of these disease-causing pathways, hyperbaric oxygen therapy (HBOT) has become popular. This therapy delivers 100% oxygen to different tissues at higher atmospheric pressures. Early research shows that HBOT improves the delivery of oxygen to the inflamed myocardium, suppress the activation of NF-κB and NLRP3 inflammasomes, lowers oxidative stress, protects mitochondrial function, and boosts immune-regulatory T-cell responses. Despite these potentially promising findings, there are still a number of important translational obstacles to overcome, such as inconsistent protocols, a lack of long-term outcome data, insufficient mechanistic profiling, and doubts about the best protocol length and patient selection. To assess safety and effectiveness in human myocarditis, future studies should aim to integrate multi-omics analyses, HBOT regimens that are already standardized, sophisticated imaging, and carefully planned early-phase clinical trials. Overall, the currently available evidence supports HBOT as a biologically plausible and potentially valuable adjunct therapy for autoimmune myocarditis, expressing the need for further mechanistic and clinical investigation.
