| dc.description.abstract | Chemotherapy-associated side effects significantly contribute to the challenges of cancer treatment, impacting the well-being of patients and complicating existing conditions. Chemotherapy-induced oedema, characterized by abnormal fluid accumulation and swelling, worsens cancer-related issues, such as impaired wound healing. This oedema may result from drug-induced vascular changes and electrolyte imbalances. Addressing such side effects is crucial for improving prognostic outcomes of cancer patients. The rat paw oedema model is a valuable tool for studying inflammatory oedema, testing novel therapies, and understanding their mechanisms. Conventional treatments for cancer chemotherapy-induced oedema have limitations, highlighting the need for alternative or complementary approaches, such as exploring natural products like Syzygium aromaticum (clove), known for its anti-inflammatory properties and potential to alleviate edema. This study examined the effects of Syzygium aromaticum ethanol extract on inflammatory oedema in rats, identified the responsible active compound (s), and explored the possible mechanism involved through computational modeling. Ethanol extract of Syzygium aromaticum (SAEE) was prepared. In vivo anti-inflammatory activities of the extract were evaluated at a specific controlled timeframe in formalin-induced paw oedema in Wistar rats. The binding affinities and interactions of the initially identified chemical constituents of the extract were modeled, through Glide standard precision and quantum polarized ligand docking, against cyclooxygenase-2 for their potential for their possible inhibitory mechanism. SAEE displayed significant time- and dose-dependent amelioration of inflammatory oedema and dose-dependent inhibition of key proinflammatory cytokines in the rat models. In silicomodeling of identified SAEE compounds revealed delphinidin, rhamnetin, and quercetin as responsible for the observed in vivo protective effects of SAEE in rat paw oedema models. This study found that Syzygium aromaticum ethanol extract effectively reduced inflammation-induced paw swelling and modulated key inflammatory markers in the rats, with the inhibitory activities of constituting delphinidin, quercetin, and rhamnetin against cyclooxygenase 2 being possibly responsible for the observed in vivo effects. Further experimental validation and dynamic simulations are needed to confirm their potential potency in more advanced preclinical and clinical models, as well as explore the mechanistic pathways involved. | |
