BSF2 is a anti-Leishmania agent. BSF2 modulates gene expression linked to ubiquitination, chromatin remodeling, and peroxisomal membrane transport pathways in Leishmania braziliensis. BSF2 downregulates TNF, IL-17, NF-kappaB, and Toll-like receptor pathways in Leishmania-infected macrophages. BSF2 exerts leishmanicidal activity against intracellular Leishmania braziliensis amastigotes. BSF2 can be used for the research of american tegumentary leishmaniasis[1].
