where
R1 is H or various substituents;
D is —NHCO—, —CONH—, —O—, —C(═O)—, —CH═CH, —C≡C—, —NR5—;
R4 is hydrogen or various substituents;
R5 is H, C1-C4 alkyl, C1-C4 alkanoyl;
E is Si or C;
R6, R7 and R8 are independently selected from C1-C8 alkyl, C2-C8 alkenyl, C2-C8 alkynyl or a stable monocyclic, bicyclic or tricyclic ring system;
G is —O—, —S—, —CHR10—, —C(═O)—;
J is —CH2—, or when G is CHR10 may also be —O— or —NH—;
R10 is H, F, —CH3, —CH2NH2, —CH2OH, —OH;
R11 is H, F, —CH3, —CH2NH2, —CH2OH, CH(OH)CH3, CH(NH2)CH3; or
R10 and R11 together define an olefinic bond, or together form a —CH2-group, thereby defining a cis or trans cyclopropyl group;
have utility in the prophylaxis or treatment of protozoal diseases such as malaria.
