A quantum chemistry investigation on antimalarial mechanism of Qinghaosu based on cleavage of the peroxide bridge / 药学学报

ABSTRACT

<p><b>AIM</b>To investigate antimalarial mechanism of Qinghaosu ( QHS) and its derivatives.</p><p><b>METHODS</b>The electronic structure of QHS and its derivatives were completely optimized and calculated at B3LYP/6-31G * level, while the route was at HF/STO-3G level.</p><p><b>RESULTS</b>The peroxide bridge is the active center of QHS and induced by ferrous iron to produce cyclic product.</p><p><b>CONCLUSION</b>Heme can link with QHS derivatives.</p>
