Phenoxypropoxybiguanides, Prodrugs of DHFR−Inhibiting Diaminotriazine Antimalarials
摘要:
A total of 34 analogues of the biguanide PS-15 (5s), a prodrug of the diaminotriazine WR99210 (8s), have been prepared. Several of them, such as 5b (PS-33) and 5m. (PS-26), maintain or exceed the in vivo activity of PS-15 while not requiring the use of highly regulated starting materials. The putative diaminotriazine metabolites of these new analogues (compounds 8) have also been prepared and shown to maintain the activity against resistant P. falciparum strains. The structure-activity relationships of biguanides 5 and putative metabolites 8 are discussed.

azaspiroketal Mannich bases perturbed phospholipid vesicles, permeabilized bacterial cells, and induced the mycobacterial cell envelope stress reporter promoter piniBAC. Surprisingly, their membrane disruptive effects did not appear to be associated with bacterial membrane depolarization. This profile was not uniquely associated with azaspiroketal Mannich bases but was characteristic of indolyl Mannich bases
