Abstract
Natural products continue to provide a platform to study biological systems. A bioguided study of cancer cell models led us to a new member of the jatrophane natural products from Jatropha gossypiifolia, which was independently identified and characterized as jatrogossone A (1). Purification and structure elucidation was performed by column chromatography and high-performance liquid chromatography-mass spectrometry and NMR techniques, and the structure was confirmed via X-ray crystallography. The unique molecular scaffold of jatrogossone A prompted an evaluation of its mode of action. Cytotoxicity assays demonstrated that jatrogossone A displays selective antiproliferative activity against cancer cell models in the low micromolar range with a therapeutic window. Jatrogossone A (1) affects mitochondrial membrane potential (ΔΨm) in a time- and dose-dependent manner. This natural product induces radical oxygen species (ROS) selectively in cancer cellular models, with minimal ROS induction in noncancerous cells. Compound 1 induces ROS in the mitochondria, as determined by colocalization studies, and it induces mitophagy. It promotes also in vitro cell death by causing cell arrest at the G2/M stage, caspase (3/7) activation, and PARP-1 cleavage. The combined findings provide a potential mechanism by which 1 relies on upregulation of mitochondrial ROS to potentiate cytotoxic effects through intracellular signaling.

Abstract
CONTEXT Jatropha isabellei Müll. Arg. (Euphorbiaceae) has been used in the traditional medicine to treat arthritis. OBJECTIVE To evaluate the anti-inflammatory and antinociceptive activities of the dichloromethane fraction (DFJi) from underground parts of J. isabellei, and to develop an analytical method to quantify the diterpene jatrophone. MATERIALS AND METHODS Anti-inflammatory and antinociceptive activities of the DFji were determined by an acute arthritis model through assessment of the paw elevation time (PET) and articular diameter (AD) of Wistar rats treated orally (50, 100 or 200 mg/kg in a single-dose), and intravenously (0.1, 1, 10, 25 or 50 mg/kg in a bolus administration). The isolation of jatrophone from the DFji was carried out and confirmed by spectroscopic techniques. A UFLC-DAD method was developed and validated. RESULTS When orally administered, the highest dose (200 mg/kg) of DFJi was able to significantly reduce the PET to 24.8 ± 1.4 s (p < 0.01), when compared with the control group (33.7 ± 1.8 s). The administration of the intravenous dose of 10 mg/kg reduced the PET to 14.8 ± 0.3 s (p < 0.001). The oral and intravenous administration of the DFJi at dose of 200 and 10 mg/kg significantly prevented the formation of edema, reducing the AD in 25.3% and 32.5% (p < 0.01), respectively. The UFLC-DAD method allowed the quantification of jatrophone, which was found to be around 90 μg/mg of fraction. DISCUSSION AND CONCLUSION The DFJi displayed antinociceptive and antiedematogenic activities, representing a promising plant product for the arthritis treatment.

Abstract
Jatropha is a nonedible oil seed plant belonging to Euphorbiaceae family. Global awareness of sustainable and alternative energy resources has propelled research on Jatropha oil as a feedstock for biodiesel production. During the past two decades, several cultivation projects were undertaken to produce Jatropha oil. In future, the increased cultivation of toxic Jatropha plants and utilization of its agro-industrial by-products may raise the frequency of contact with humans, animals, and other organisms. An attempt was thus made to present known information on toxicity of Jatropha plants. The toxicity of Jatropha plant extracts from fruit, seed, oil, roots, latex, bark, and leaf to a number of species, from microorganisms to higher animals, is well established. Broadly, these extracts possess moluscicidal, piscicidal, insecticidal, rodenticidal, antimicrobial, and cytotoxic properties, and exert adverse effects on animals including rats, poultry, and ruminants. The toxicity attributed to these seeds due to their accidental consumption by children is also well documented. An attempt was also made to identify areas that need further study. The information provided in this review may aid in enhancing awareness in agroindustries involved in the cultivation, harvesting, and utilization of Jatropha plants and its products with respect to the potential toxicity of Jatropha, and consequently in application and enforcement of occupational safety measures. Data on the wide range of bioactivities of Jatropha and its products were collated and it is hoped will create new avenues for exploiting these chemicals by the phamaceutical industry to develop chemotherapeutic agents.

JOURNAL OF ETHNOPHARMACOLOGY 2007; 111:553-9.

Abstract
A new jatrophone derivative (6), jatrophone (3), jatropholone A (4) and jatropholone B (5), acetyl aleuritolic acid (1), cyperenoic acid (2) and a monoterpene were isolated from the rhizomes of the Paraguayan crude drug Jatropha isabelli. The compounds were characterized by spectroscopic means. The gastroprotective effect of jatrophone, jatropholone A and B as well as 9beta,13alpha-dihydroxyisabellione 6 and the triterpene 1 was assessed in the HCl/EtOH-induced gastric lesions model in mice. Jatrophone elicited a strong gastroprotective effect with no significant differences between 25, 50 or 100 mg/kg and reducing lesions from 88 to 93%. The jatropholones A and B showed remarkable differences in the gastroprotective assay. Jatropholone A presented a dose-related response, with maximum effect (54% lesion reduction) at the highest dose (100 mg/kg), jatropholone B showed a strong action at all the doses, reducing lesions by 83-91%. The cytotoxicity of the compounds was assessed towards fibroblasts and AGS cells. Jatrophone was toxic against both cell lines (IC50 values: 2.8 and 2.5 microM, respectively). Jatropholone B (5) was not cytotoxic while jatropholone A (4) displayed a selective effect against AGS cells (IC50: 49 microM). The relevance of stereochemistry in the biological effects is clear comparing the effect of jatropholone A and B against AGS cells, with IC50 values of 49 and > 1000 microM for the beta and alpha C-16 isomers, respectively. The results provide scientific support for the use of "yagua rova" as a gastroprotective crude drug in Paraguayan traditional medicine.
