  A series of structurally simple chloroquine chemosensitizing dibemethin derivatives that inhibit chloroquine transport by PfCRT

  摘要：

  A series of 12 new dibemethin (N-benzyl-N-methyl-1-phenylmethanamine) derivatives bearing an Naminomethyl group attached to the one phenyl ring and an H, CI, OCH3 or N(CH3)(2) group on the other have been synthesized. These compounds all showed strong chloroquine chemosensitizing activity, comparable to verapamil, when present at 1 mu M in an in vitro culture of the chloroquine-resistant W2 strain of the human malaria parasite, Plasmodium falciparum. Their N-formylated derivatives also exhibited resistance-reversing activity, but only at substantially higher IC10 concentrations. A number of the dibemethin derivatives were shown to inhibit chloroquine transport via the parasite's 'chloroquine resistance transporter' (PfCRT) in a Xenopus laevis oocyte expression system. The reduced resistance-reversing activity of the formylated compounds relative to their free amine counterparts can probably be ascribed to two factors: decreased accumulation of the formylated dibemethins within the parasite's internal digestive vacuole (believed to be the site of action of chloroquine), and a reduced ability to inhibit PfCRT. The resistance-reversing activity of the compounds described here demonstrates that the amino group need not be attached to the two aromatic rings via a three or four carbon chain as has been suggested by previous QSAR studies. These compounds may be useful as potential side chains for attaching to a 4,7-dichloroquinoline group in order to generate new resistance-reversing chloroquine analogues with inherent antimalarial activity.

  A series of 4-amino-7-chloroquinolines with dibenzylmethylamine (dibemethin) side chains were shown to inhibit synthetic hemozoin formation. These compounds were equally active against cultures of chloroquine-sensitive (D10) and chloroquine-resistant (K1) Plasmodium falciparum. The most active compound had an IC50 value comparable to that of chloroquine, and its potency was undiminished when tested in three additional chloroquine-resistant strains. The three most active compounds exhibited little or no cytotoxicity in a mammalian cell line. When tested in vivo against mouse malaria via oral administration, two of the dibemethin derivatives reduced parasitemia by over 99%, with mice treated at 100 mg/kg surviving the full length of the experiment. Three of the compounds were also shown to inhibit chloroquine transport via the parasite's chloroquine-resistance transporter (PfCRT) in a Xenopus oocyte expression system. This constitutes the first example of a dual-function antimalarial for which the ability to inhibit both hemozoin formation and PfCRT has been demonstrated directly.
