Leishmania (Viannia) braziliensis growth in vitro culture relies more on folic acid availability than Leihsmania (Leishmania) amazonensis

open access: yesMemorias do Instituto Oswaldo Cruz, 2005
We compared the in vitro growth of promastigotes from two Leishmania species in TC-100 and Schneider media. Leishmania (Leishmania) amazonensis replication rates were similar in both tissue culture media and reached maximum rates by 48 h.

Unveiling the Leishmanicidal Mechanism of 4‐Nerolidylcatechol Isolated From Piper peltatum Against Leishmania infantum

open access: yesChemistry &Biodiversity, Volume 23, Issue 1, January 2026.
ABSTRACT The present study assessed the leishmanicidal activity of 4‐nerolidylcatechol (4‐NC) (1) isolated from Piper peltatum leaves against promastigotes and amastigotes of Leishmania amazonensis, L. braziliensis, and L. infantum. The plant was fractionated, leading to the isolation and chemical identification of 4‐NC (1). Biochemical techniques were
