The capacity of hematopoietic tissues to produce and mobilize phagocytes to the site of infection and tumor growth is of central importance to mediate the early immunological response. In this perspective, studies from our laboratory have defined Listeria monocytogenes infection and the Ehrlich
Gallic acid (1) and methyl gallate (2) were isolated from Juca, a Brazilian folk medicine, fruits of Caesalpinia ferrea MART (Leguminosae), decreased significantly the average number of papillomas per mouse in the experiment of the promoting effects of 12-O-tetra- decanoylphorbol-13-acetate (TPA) on
The anti-tumor promoting effects of fruits of Caesalpinia ferrea MART. (Leguminosae) were tested by the in vitro Epstein-Barr virus early antigen (EBV-EA) activation assay, and its active constituents were identified as gallic acid (1) and methyl gallate (2). A total of 49 related compounds of 1 and
Colorectal cancer is noted for being one of the most frequent of tumors, with expressive morbidity and mortality rates. In new drug discovery, plants stand out as a source capable of yielding safe and high-efficiency products. Well known in Brazilian popular medicine, Libidibia ferrea (Mart. Ex
Libidibia ferrea (juca) is a plant belonging to the Fabaceae (Leguminosae) family, whose antioxidant activity has been widely described in the literature. We evaluated this parameter of Aqueous ethanol extract (AE), ethyl acetate (ACO), chloroform (CLO) and hexane (HEX) extracts of L. ferrea. We
Libidibia ferrea (L. ferrea) has been used in folk medicine to treat several conditions and to prevent cancer. This study performed a chromatographic analysis of the crude aqueous extract of Libidibia ferrea (Mart. ex. Tul.) L.P. Queiroz (LfAE) leaves and evaluated its in vivo Libidibia ferrea has been used in folk medicine throughout Brazil, and this study evaluated the biological activities of crude extract (CE) as well as a partially purified fraction (F80) obtained from its pods. Results from the MTT assay revealed that only F80 inhibited NCI-H292 cell growth;
