“…It was about 250 times more toxic than thymol (LC50 480.20 μg/mL), which was used as a reference substance. In agreement with our data, a number of works indicates that thymol showed several biological activities, such as cytotoxicity (Buyukleyla & Rencuzogullari, 2009), antifungal, genotoxic (Stammati et al, 1999) and antileishmanial (De Medeiros et al, 2011) effects. Moreover, recent published data showed that thymol significantly increased the sister chromatid exchange, especially at the lower concentrations (75 and 100 µg/mL), induced both the chromosome aberration (CA) and frequency of micronucleus (MN), as well as dose-dependently decreased the nuclear division index (NDI) in human peripheral lymphocytes (Buyukleyla & Rencuzogullari, 2009).…”

“…In T. cruzi, both eugenol (Santoro, Cardoso, Guimarães, Mendonça et al., 2007) and thymol (Santoro, Cardoso, Guimarães, Salgado et al., 2007) caused cytoplasmic swelling, rounding of the cell body, and altered nuclear morphology. In Leishmania major , both eugenol (Ueda‐Nakamura et al., 2006) and thymol (de Medeiros et al., 2011) affected mitochondria. In the yeast Candida albicans , both eugenol and thymol altered membrane morphology (Braga, Sasso, Culici, & Alfieri, 2007).…”

“…In the yeast Candida albicans , both eugenol and thymol altered membrane morphology (Braga, Sasso, Culici, & Alfieri, 2007). Although neither compound affected the plasma membrane of T. cruzi (Santoro, Cardoso, Guimarães, Mendonça et al., 2007; Santoro, Cardoso, Guimarães, Salgado et al., 2007), eugenol altered the mitochondrial membrane in L. donovani (Ueda‐Nakamura et al., 2006), and thymol caused membrane wrinkling and submembrane accumulation of lipid droplets in L. amazonensis (de Medeiros et al., 2011). Given the similar chemical structures and modes of action of eugenol and thymol, we predicted that these compounds would behave additively.…”

“…The effect of thymol, isolated from L. sidoides, has been demonstrated against the promastigote form of Leishmania amazonensis (Medeiros et al, 2011). Antiprotozoal activity also was observed against Trypanosoma cruzi (Santoro et al, 2007;Escobar et al, 2010a).…”

“…and Lippia sidoides Cham., popularly known as ''canelinha'' and ''alecrim-pimenta'', respectively. These species have shown antibacterial action and against promastigotes and amastigotes of Leishmania amazonensis (Costa et al, 2008;Medeiros et al, 2011). The volatile oils (VOs) of these plants also exhibit antimalarial activity against Plasmodium berghei in mice and Plasmodium falciparum in vitro (Mota et al, 2012).…”
