Abstract: Dihydroartemisinin derivatives with antimalarial activity against P. falciparum resistant to mefloquine are proposed with the aid of quantum chemistry and multivariate analysis methods (PCA, KNN, and SIMCA). The principal component analysis (PCA) and hierarchical cluster analysis (HCA) showed that the descriptors: molecular softness (MS), total surface area (TSA), Randic's index, path-1 molecular connectivity-average (CHl1A), bond information index (BIC), shape index based on paths of length 2 of Kier (2K), and directional (related to molecular size, dimension: axis I and weight: van der Waals' volume) and non-directional (related to linear contribution to the total molecular size and weight: van der Waals' volume) WHIM-31) indices (L1v and Tv), respectively, are responsible for the classification between the higher and lower antimalarial. activity of the derivatives. The compounds predicted as of high activity by the three methods are 22 and 28 in Fig. 2. (C) 2001 Published by Elsevier Science B.V.
