AB  - The syntheses and antiplasmodial activities of various substituted aminoquinolines coupled to an adamantane carrier are described. The compounds exhibited pronounced in vitro and in vivo activity against Plasmodium berghei in the Thompson test. Tethering a fluorine atom to the aminoquinoline C(3) position afforded fluoroaminoquinolines that act as intrahepatocytic parasite inhibitors, with compound 25 having an IC50 = 0.31 mu M and reducing the liver load in mice by up to 92% at 80 mg/kg dose. Screening our peroxides as inhibitors of liver stage infection revealed that the tetraoxane pharmacophore itself is also an excellent liver stage P. berghei inhibitor (78: IC50 = 0.33 mu M). Up to 91% reduction of the parasite liver load in mice was achieved at 100 mg/kg. Examination of tetraoxane 78 against the transgenic 3D7 strain expressing luciferase under a gametocyte-specific promoter revealed its activity against stage IV-V Plasmodium falciparum gametocytes (IC50 = 1.16 +/- 0.37 mu M). To the best of our knowledge, compounds 25 and 78 are the first examples of either an 4-aminoquinoline or a tetraoxane liver stage inhibitors.

AB  - Steroidal and adamantane aminoacridine derivatives were prepared and tested as both botulinum neurotoxin (BoNT) inhibitors and antimalarials. Steroid-bound acridines provided good potency against both the BoNT/A and BoNT/B light chains (LCs). The observed inhibition of the BoNT/B LC by ca. 50% is the highest attained inhibitory activity against this serotype by acridine-based compounds to date. With respect to the antimalarial activity, the adamantane acridines were the most potent derivatives (IC50 = 6-9 nM, SI > 326), indicating that an adamantyl group is a better carrier than a steroidal motif for this indication. .
AB  - Sintetisani su derivati steroidnih i adamantil-akridina i ispitana je njihova inhibitorna aktivnost prema botulinum neurotoksinima (BoNT) i parazitu malarije. Steroidni akridini pokazuju dobru inhibiciju prema kratkom nizu (LCs) BoNT/A i BoNT/B. Ostvarena inhibicija BoNT/B LC od oko 50% je najviša postignuta vrednost akridinskih derivata prema ovom serotipu. Adamantil-akridinski derivati su pokazali najveću antimalarijsku aktivnost (IC50 u opsegu 6-9 nM, SI > 326), pokazujući da je adamantil-grupa bolji nosač farmakofore u poređenju sa steroidnim, prema ovoj indikaciji. .
