Activities of hexadecylphosphocholine (miltefosine), AmBisome, and sodium stibogluconate (Pentostam) against Leishmania donovani in immunodeficient scid mice.

چکیده
In both scid and BALB/c mouse-Leishmania donovani models, hexadecyphosphocholine (miltefosine) and AmBisome had similar levels of activity. In contrast, sodium stibogluconate (Pentostam) was significantly less active against L. donovani in scid mice than in BALB/c mice. The in vitro anti-leishmanial activity of miltefosine was similar in peritoneal macrophages derived from both scid and BALB/c mice, whereas Pentostam and AmBisome were significantly more active in the latter.

Tucaresol, a novel immunomodulator, was inactive against Leishmania donovani amastigotes in both peritoneal and bone marrow macrophages in vitro at concentrations between 100 and 1 microM, with toxicity to macrophages and parasites at 300 microM. However, against L. donovani in BALB/c mice at doses between 80 and 1.25 mg/kg of body weight administered once daily by the oral route during days 7 ...

The in-vitro activities of four anticancer alkyllysophospholipids, ET-18-OCH3 (edelfosine), hexadecylphosphocholine (miltefosine), ilmofosine and SRI 62-834, were determined with ED50 values for Leishmania donovani and Trypanosoma cruzi amastigotes between 0.2 and 5.0 microM and for Trypanosoma brucei trypomastigotes between 7.0 and 50.8 microM. In BALB/c mice miltefosine and ilmofosine were th...
متن کاملThe in vivo susceptibility of Leishmania donovani to sodium stibogluconate is drug specific and can be reversed by inhibiting glutathione biosynthesis.
Resistance to pentavalent antimonial (Sb(v)) agents such as sodium stibogluconate (SSG) is creating a major problem in the treatment of visceral leishmaniasis. In the present study the in vivo susceptibilities of Leishmania donovani strains, typed as SSG resistant (strain 200011) or SSG sensitive (strain 200016) on the basis of their responses to a single SSG dose of 300 mg of Sb(v)/kg of body ...

The in vitro leishmanicidal activity of miltefosine® (Zentaris GmbH) was assessed against four medically relevant Leishmania species of Brazil: Leishmania (Leishmania) amazonensis, Leishmania (Viannia) braziliensis, Leishmania (Viannia) guyanensis and Leishmania (Leishmania) chagasi. The activity of miltefosine against these New World species was compared to its activity against the Old World s...
