Ferulate Anion Intercalated into Zn/Al Layered Double Hydroxide: A Promising Intercalation Compound for Inhibition of Leishmania (L.) amazonensis
Ferulic acid (FERH) is known to exert leishmanicidal action against Leishmania (Leishmania) amazonensis. In this study, the ferulate anion (FER–) was intercalated into a layered double hydroxide (LDH) for FER– delivery during an antileishmania in vitro test. The LDH-FER– intercalation compound was prepared by coprecipitation and was characterized by X-ray powder diffraction, thermogravimetry, UV-Vis, infrared, and Raman spectroscopy analyses. Leishmania (L.) amazonensisin vitro assays were conducted to assess the LDH-FER– potential. LDH-FER– was found to promote a dose-dependent reduction of L. (L.) amazonensis amastigotes (intracellular form, half maximal inhibitory concentration (IC50) = 1.78 µg mL-1) without exerting a deleterious effect on the host macrophages (medium cytotoxic concentration (CC50) = 212.61 µg mL-1 and selectivity index = 119.4). LDH-FER– was found to be an effective inhibitor of the amastigote form of L. (L.) amazonensis, suggesting that LDH-FER– was able to deliver FER– inside the parasitophorous vacuoles where the pH is more acidic.
