Abstract

An improved method for the synthesis of (6′R)-6′-C-methylneplanocin A (RMNPA, 2), a potent S-adenosyl-L-homocysteine (AdoHcy) hydrolase inhibitor, was developed via a chelation-controlled stereoselective addition of MeTiCl₃ to the neplanocin A 6′-aldehyde derivative 6. Compound 2 effectively inhibited the growth of malaria parasites both in vitro and in vivo. The antimalarial EC₅₀ value of 2 against Plasmodium berghei in mice was 1.0 mg/kg/day, which was superior to that of chloroquine (EC₅₀ = 1.8 mg/kg/day).
