Inhibition of cholesterol biosynthesis at post-squalene steps provide the alternative to classic statin therapy. Sterol-14α-demethylase (CYP51) is one of potential targets for such inhibition. In this study screening of potential ligands of human CYP51 (CYP51A1) among natural low-weight compounds containing steroid-like moiety has been performed by means of integration of surface plasmon resonance and spectral titration methods. Four compounds (betulafolientriol, holothurin A, theasaponin, capsicosine) exhibited high affinity to the active site of CYP51A1. These data extend the known range of compounds, which may be used as specific inhibitors of CYP51.
