  8,8-Dialkyldihydroberberines with Potent Antiprotozoal Activity

  摘要：

  Semisynthetic 8,8-dialkyldihydroberberines (8,8-DDBs) were found to possess mid- to low-nanomolar potency against Plasmodium falciparum blood-stage parasites, Leishmania donovani intracellular amastigotes, and Trypanosoma brucei brucei bloodstream forms. For example, 8,8-diethyldihydroberberine chloride (5b) exhibited in vitro IC50 values of 77, 100, and 5.3 nM against these three parasites, respectively. In turn, two 8,8-dialkylcanadines, obtained by reduction of the corresponding 8,8-DDBs, were much less potent against these parasites in vitro. While the natural product berberine is a weak DNA binder, the 8,8-DDBs displayed no affinity for DNA, as assessed by changes in the melting temperature of poly(dA.dT) DNA. Selected 8,8-DDBs showed efficacy in mouse models of visceral leishmaniasis and African trypanosomiasis, with 8,8-dimethyldihydroberberine chloride (5a) reducing liver parasitemia by 46% in L. donovani-infected BALB/c mice when given at an intraperitoneal dose of 10 mg/kg/day for five days. The 8,8-DDBs may thus serve as leads for discovering new antimalarial, antileishmanial, and antitrypanosomal drug candidates.
