The bark of Croton cajucara Benth, is used in Brazilian folk medicine as an infusion to treat gastrointestinal disorders. The aim of the present study was to assess the mechanisms involved in the antiulcerogenic activity of dehydrocrotonin (DHC), a diterpene isolated from C. cajucara bark. We
Diterpenes exhibit potent antineoplastic properties against human and murine carcinoma cell lines. trans-Dehydrocrotonin from Croton cajucara, a Brazilian medicinal plant, is a nor-diterpene with antiulcerogenic activity. In this work, we examined the effect of trans-dehydrocrotonin (t-DCTN) on the
The effect of three new derivatives from dehydrocrotonin (DHC-compound I) on gastric damage in different animal models including gastric ulceration induced by a necrotic agent and hypothermic restrained-stress was studied: compound II (produced by reducing the cyclohexenone moiety of DHC with
Derivatives of dehydrocrotonin (DHC; Compound I) with different anti-ulcerogenic properties but less toxicity were produced by reducing the cyclohexenone moiety of DHC with NaBH4 (Compound II), reducing the cyclohexenone and lactone moieties with LiAlH4 (Compound III) and transforming the lactone
Oxidative stress can be involved in several cellular responses, such as differentiation, apoptosis and necrosis. Dehydrocrotonin (DCTN, diterpene lactone) from Croton cajucara, Brazilian medicinal plant, slightly induced NBT-reducing activity. In presence of protein phosphatase inhibitors
Dehydrocrotonin (DHC) is a diterpene lactone obtained from Croton cajucara (Sacaca). Dimethylamide-crotonin (DCR), a DHC derivative, has a similar inhibitory effect on leukemic HL60 cells than its parent compound evaluated by different endpoints of cytotoxicity. No cytotoxicity or morphological
A variety of stimuli can induce cells to undergo apoptosis, with one of the most reproducible inducers being mild oxidative stress following exposure to anticancer agents. Apoptosis involves events mediated by cysteine proteases (caspases) that are classified as initiators (-8, -9 and -12) or
