AB  - Significantly more potent second generation 4-amino-7-chloroquinoline (4,7-ACQ) based inhibitors of the botulinum neurotoxin serotype A (BoNT/A) light chain were synthesized. Introducing an amino group at the C(3) position of the cholate component markedly increased potency (IC50 values for such derivatives ranged from 0.81 to 2.27 mu M). Two additional subclasses were prepared: bis(steroidal)-4,7-ACQ derivatives and bis(4,7-ACQ)cholate derivatives; both classes provided inhibitors with nanomolar-range potencies (e.g., the K-i of compound 67 is 0.10 mu M). During BoNT/A challenge using primary neurons, select derivatives protected SNAP-25 by up to 89%. Docking simulations were performed to rationalize the compounds' in vitro potencies. In addition to specific residue contacts, coordination of the enzyme's catalytic zinc and expulsion of the enzyme's catalytic water were a consistent theme. With respect to antimalarial activity, the compounds provided better IC90 activities against chloroquine resistant (CQR) malaria than CQ, and seven compounds were more active than mefloquine against CQR strain W2.

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. .

AB  - Botulinum neurotoxins (BoNTs), composed of a family of seven serotypes (categorized A-G), are the deadliest of known biological toxins. The activity of the metalloprotease, light chain (LC) component of the toxins is responsible for causing the life-threatening paralysis associated with the disease botulism. Herein we report significantly more potent analogs of novel, lead BoNT serotype A LC inhibitor 2,5-bis(4-amidinophenyl)thiophene (K-i = 10.881 mu M +/- 0.90 mu M). Specifically, synthetic modifications involved simultaneously replacing the lead inhibitor's terminal bis-amidines with secondary amines and the systematic tethering of 4-amino-7-chloroquinoline substituents to provide derivatives with K-i values ranging from 0.302 mu M (+/- 0.03 mu M) to 0.889 mu M (+/- 0.11 mu M).
