In-silico, in-vitro antioxidant and anti-inflammatory potential of cynanchum callialatum leaves

Inflammatory disorders, including various forms of rheumatic diseases, are a serious global issue. For the treatment of such disorders, the world's population is increasingly turning to herbal treatments. Many plants have been tested for anti-inflammatory and anti-arthritic properties, but only a handful have reached the therapeutic level. The purpose of this research is to determine the anti-inflammatory potential of Cynanchum callialatum leaves using in-silico and in-vitro investigations. The leaves' ethanol extract was produced and analysed for antioxidant capability using the DPPH and nitric oxide scavenging assays. Through molecular docking investigations, the phytoconstituents found in the leaves were docked against PLA2, COX-1, COX-2, and 5-LOX proteins. µAt 1000 µg/ml, the leaf extract had a maximum inhibitory percentage of 67.61 percent (nitric oxide) and 70.41 percent (DPPH), with an IC50 of 414.4 g/ml (nitric oxide) and 446.6 µg/ml (DPPH) (DPPH). The docking investigations indicated that the ligands inhibited the PLA2 protein via a mechanism and were submitted to a PLA2 inhibition experiment. The extract inhibited the enzyme by 71.92 percent at 1000 µg/ml, with an IC50 of 289.8 µg/ml. To assess the full inhibitory efficacy of PLA2, the phytoconstituents must be exposed to additional preclinical and clinical research.
