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.

The synthesis of novel N-tosyl tetraaza cyclophanes and N-tosyl diaza cyclophane incorporating m-terphenyl as spacer units is described. Anti-arthritic activity was studied by inhibition of the protein denaturation method (bovine serum albumin). All the N-tosyl aza cyclophanes exhibit excellent anti-arthritic activity. Anti-inflammatory activity of the synthesized cyclophanes was investigated using the human red blood cells (HRBC) membrane stabilization method and some of the N-tosyl aza cyclophanes exhibited good anti-inflammatory activity.

Ochna schweinfurthiana has been used in traditional medicine to treat pain, inflammation, and arthritis. It is a rich source of complex dimers of flavonoids with potential use as templates for the development of therapeutic drugs. Hence, the aim of this study was to study the phytochemical content and evaluate the in vitro cytotoxic, genotoxic, and anti-inflammatory activities of the aqueous extract of Ochna schweinfurthiana bark (OSE). Phytochemical study was carried out according to LC-MS procedures, while isolation was carried out using thin layer and column chromatographies. Cytotoxicity was investigated by the mitochondrial viability [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide] (MTT) method while genotoxicity potential of the extract was ascertained using the Salmonella typhimurium test strains TA98 and TA100. The anti-inflammatory effect of OSE was evaluated by the in vitro inhibition of 15-lipooxygenase enzyme and bovine serum albumin denaturation (BSA) assays. The investigation of compounds extracted from OSE led to the identification and isolation of six known compounds, namely, hemerocallone (9), 6,7-dimethoxy-3’-4’-dimethoxyisoflavone (10), lithospermoside (13), amentoflavone (14), agathisflavone (15), and β-D-fructofuranosyl-α-D-glucopyranoside (17). In the anti-inflammatory assay, aqueous extracts of the bark showed selective inhibition of 15-lipooxygenase with IC50 value of 32.2±0.36  μg/mL and the result of the bovine serum albumin denaturation assay with IC50 value of 130± 5.78 μg/mL showed moderate activity. The toxicity assay indicated that OSE are noncytotoxic on Vero cell line with LC50 value of 50 mg/mL and nongenotoxic toward Salmonella typhimurium tester strain TA98 and TA100. Result from this study supports the traditional use of the selected medicinal plants in Cameroon for the treatment of inflammatory conditions. Noncytotoxicity and nongenotoxicity of OSE suggest that this plant is safe for use.
