OBJECTIVE To assess the safety of Brucea javanica and Cantharidin combined with chemotherapy in treating patients with non-small-cell lung carcinoma. METHOD A consecutive cohort of patients with NSCLC were divided into four groups: experimental group A treated with Brucea javanica injection combined with chemotherapy; experimental group B with Cantharidin injection combined with chemotherapy;...
Using small molecule probes to understand gene function is an attractive approach that allows functional characterization of genes that are dispensable in standard laboratory conditions and provides insight into the mode of action of these compounds. Using chemogenomic assays we previously identified yeast Crg1, an uncharacterized SAM-dependent methyltransferase, as a novel interactor of the pr...
Cancer metastasis becomes an initial cause of cancer death in human population. In many cancers, it has been shown that the high levels of matrix metalloproteinase (MMP)-2 and/or MMP-9 are associated with the invasive phenotypes of cancer cells. In this study, we investigated the effects of cantharidin, a derivative of blister beetles which is one of the traditional Chinese medicines, on the ad...
We present evidence of a possible case of self-medication in a lekking bird, the great bustard Otis tarda. Great bustards consumed blister beetles (Meloidae), in spite of the fact that they contain cantharidin, a highly toxic compound that is lethal in moderate doses. In addition to anthelminthic properties, cantharidin was effective against gastrointestinal bacteria that cause sexually-transmi...
The cantharidin blister model provides an in vivo assessment of the innate inflammatory response in humans. It allows researchers to profile the acute and resolving inflammatory response in healthy and diseased states and for the design of crossover trials for the testing of new treatments for acute inflammation. Below we describe the materials and methods required to prepare, induce, aspirate ...
Cantharidin, a natural vesicant, inhibits the activity of several PPP family phosphatases, displays antitumor activity, and induces apoptosis in many types of tumor cells. However, the molecular mechanisms underlying the antitumor activity of cantharidin are not clear. Here, doseresponse studies confirm a strong correlation between the suppression of phosphatase activity and cell death. Flow cy...
Cantharidin, a vesicant agent, and asiaticoside, which promotes the healing of skin ulcers, were tested for carcinogenicity by topical applications to the skin of hairless mice. A short-term tetrazolium test indicated that both compounds were weak carcinogens. The compounds were then separately painted twice weekly on the dorsal skin up to about 20 months; some of the mice had previously been i...
As part of a larger study synthesizing a more directed form of chemotherapy, we have begun to assess the efficacy of different potential toxins that could be delivered locally rather than systemically. In doing so, we hope to reduce the systemic side effects commonly observed, while maintaining a high level of toxicity and eliminating the need for metabolic alterations. In a search for this mor...
