Plants are an entity essential to the function of the biosphere as well as human health. In the context of human health, this research investigated the effect of Lasia spinosa (Lour) leaf methanolic extracts (LSML) on antioxidative enzymes and gene expression as well as biochemical and histological markers in a streptozotocin (STZ)-induced diabetes model. Fructose-fed streptozotocin (STZ)-induced diabetic animals were subjected to a four-week intervention followed by the assessment of the animal’s blood and tissues for enzymatic, biochemical, histological, and genetic changes. LSML-treated groups were shown to decrease plasma glucose levels and improve body and organ weights compared to the untreated group in a dose-dependent manner. At the doses of 125 and 250 mg/kg b.w., LSML were able to normalize serum, hepatic, and renal biochemical parameters and restore the pancreas, kidney, liver, and spleen tissue architectures to their native state. A considerable increase (p < 0.01) of liver antioxidant enzymes CAT, SOD, GSH, and a decrease of MDA level in LSML-treated groups were found at higher doses. The improved mRNA expression level of antioxidant genes CAT, SOD2, PON1, and PFK1 was also found at the doses of 125 mg/kg and 250 mg/kg BW when compared to untreated control groups. The results demonstrate that LSML impacts the upregulation of antioxidative gene expressions, thus improving the diabetic complications in animal models which need to be affirmed by compound-based antioxidative actions for therapeutic development.

This research investigated pharmacological properties mainly the anti-inflammatory, anthelmintic, thrombolytic and anxiolytic potential of methanol extract of Syzygium samarangense (MESS) var. parviflorum. Anti-inflammatory action by bovine serum albumin, egg albumin denaturation and membrane stabilization, anthelmintic by live parasites, thrombolytic by clot lysis and anxiolytic by elevated plus maze (EPM) and light and dark box (LDB) tests were measured. The four targeted pharmacological properties were further justified using the most prevalent compounds, isolated from this plant, to be undergone for their pharmacokinetic property’s analyses, sitemap analyses and lignad-receptor interactions by computational models through SwissADME and Schrödinger, 2018 softwares against PDB 6COX, 6D6T, 1JFF receptors. MESS was found to display statistically significant (P < 0.05) inhibition of Bovine Serum albumin and Egg albumin denaturation compared to reference drug diclofenac sodium. Remarkable vermicidal effect on the paralysis and death of anthelmintic parasites was observed at MESS concentration 200 mg/dL. A nondescript clot lysis of MESS compared to streptokinase was evident in in vitro thrombolytic assay. MESS increased the number of times the animal crossed from one compartment to the other and the time spent in the brightly-lit chamber of the LDB. Three-methylchalcone derivatives out of seven MESS compounds were undertaken, based on cut off value and sitemap prediction score, for further ligand-receptor binding efficiency. All these three compounds showed promising docking score, glide emodel and glide energy against PDB 6COX, 6D6T and 1DDJ, plasmin proteins demonstrating the prospects of MESS to be materialized for anti-inflammatory, anthelmintic, and thrombolytic therapeutics with further clarification.
