Urease inhibition potential and molecular docking of dihydroquercetin and dihydromyricetin isolated from Picea smithiana (wall) Boiss

摘要: Three flavanonol namely quercetin, dihydroquercetin and dihydromyricetin were isolated from ethyl acetate fraction of Picea smithiana (wall) Boiss by using standard isolation schemes. The evaluated for their enzyme inhibition potential against urease, carbonic anhydrase Phosphodiesterases-I. Flavanonol showed significant activity urease with IC50 value 29.73 ± 1.22 μM, While quercetin found to be weak inhibitors values 208.87 2.11 202.87 2.01 μM respectively. Thiourea was used as a the (IC50=21 0.12). On other hand 2 potent phosphodieseterase-1 when compared EDTA (IC50=273 1.69 μM). Newly identified may lead discovery new drug treat urolithiasis, cardiovascular associated disorder. In silico designing plays an important role in target. Compounds 1-3 screen docking study. docked conformations compounds reference thiourea potency 1-3. From statistics, it is observed that binding affinity compound 3 -8.5 kcal/mol (Autodock vina energies), which best than (-3.4 kcal/mol).
