Background Cyclotides are disulfide-rich miniproteins with the unique structural features of a circular backbone and knotted arrangement of three conserved disulfide bonds. These features make them exceptionally stable and they have applications as plant defense (insecticidal) agents and stable drug frameworks. So far they have been found mainly in two plant families, including in every species...

Background The genus Guettarda (Rubiaceae) comprises plants widely distributed in tropical areas [1]. Regarding the Guettarda sericea species, the literature shows that there is a lack of botanical and phytochemicals studies [2]. Thus, the present study aimed to evaluate the antibacterial effect of ethanol extract of leaves of G. sericea (EEFGS) on the growth of Streptococcus oralis ATCC 10557 ...
