Lactoferrin-modified Betulinic Acid-loaded PLGA nanoparticles are strong anti-leishmanials.


Visceral Leishmaniasis (VL), caused by the protozoan parasite Leishmania donovani, is a potentially fatal disease. The only orally bioavailable drug miltefosine is toxic and the effective liposomal Amphotericin B (AmBisome) is limited by its prohibitive cost and requirement for parenteral administration. Therefore, finding a new potential drug candidate and an alternative delivery system is imperative. We report that Betulinic acid (BA), a pentacyclic triterpenoid from Betula alba bark, was loaded onto uniformly spherical PLGA nanoparticles (BANPs; diameter 187.5 ± 5.60 nm) coated with Lactoferrin (Lf-BANPs). The amastigotes count in macrophages was more effectively reduced by Lf-BANP than BA and BANP. Lf-BANPs reduced the pro-parasitic, anti-inflammatory cytokine IL-10, but increased nitric oxide (NO), production in L. donovani-infected macrophages indicating that Lf-BANP possesses a significant anti-leishmanial activity.
