摘要

The paper studies the complexation of pravastatin with transition metal ions (Co2+, Mn2+) using high-resolution nuclear magnetic resonance (NMR) spectroscopy and molecular dynamics (MD) methods. It was shown that the presence of transition metal ions leads to changes in 1H, 13C NMR chemical shifts of CH2-14, CH-15, CH2-16 groups of pravastatin. MD modeling for systems of pravastatin aqueous solutions with cobalt and manganese ions confirms the experimental assumption about the most probable area of metal ions near the pravastatin molecule.
