Özet

Plant phenolics are known to display many pharmacological activities. In the current study, eight phenolic compounds, e.g., luteolin 5-O-beta-glucoside (1), methyl rosmarinate (2), apigenin (3), vicenin 2 (4), lithospermic acid (5), soyasaponin II (6), rubiadin 3-O-beta-primeveroside (7), and 4-(beta-D-glucopyranosyloxy) benzyl 3,4-dihydroxybenzoate (8), isolated from various plant species were tested at 0.2 mM against carbonic anhydrase-II (CA-II) and urease using microtiter assays. Urease inhibition rate for compounds 1-8 ranged between 5.0-41.7%, while only compounds 1, 2, and 4 showed a considerable inhibition over 50% against CA-II with the IC50 values of 73.5 +/- 1.05, 39.5 +/- 1.14, and 104.5 +/- 2.50 mu M, respectively, where IC50 of the reference (acetazolamide) was 21.0 +/- 0.12 mu M. In silico experiments were also performed through two docking softwares (Autodock Vina and i-GEMDOCK) in order to find out interactions between the compounds and CA-II. Actually, compounds 6 (30.0%) and 7 (42.0%) possessed a better binding capability toward the active site of CA-II. According to our results obtained in this study, among the phenolic compounds screened, particularly 1, 2, and 4 appear to be the promising inhibitors of CA-II and may be further investigated as possible leads for diuretic, anti-glaucoma, and antiepileptic agents.
