生物活性:
PT4 is a therapeutic agent against Cutaneous leishmaniasis (CL). PT4 is effective against both species of Leishmania, with IC50s of 125.18 and 233.18 μM for L. amazonensis and L. braziliensis, respectively. PT4 decreases of mitochondrial membrane potential and increases production of reactive oxygen species, which leads to parasite death. PT4 has a potent in vivo anti-inflammatory activity.

体外研究:
PT4 (0-1256.5 μM, 48 hours) can inhibit mammalian cells viability.PT4 (314.1-19.6 μM, 48 hours) inhibits the growth of promastigote and amastigote of L. amazonensis and L. braziliensis promastigotes.PT4 causes depolarization of the mitochondrial membrane of L. amazonensis and L. braziliensis promastigotes and increasing ROS in mitochondria.
