cucurbitacin d/trichosanthes kirilowii

Trichosanthes kirilowii tuber is a traditional medicine which exhibits various medicinal effects including antidiabetic and anticancer activities in several cancer cells. Recently, it was reported that Cucurbitacin D (CuD) isolated from Trichosanthes kirilowii also induces apoptosis in several

The aim of the present study is to examine the effects of the anti-tumor component isolated from Trichosanthes kirilowii on human hepatocellular carcinoma cells. Using Sephadex G-25 column chromatography, Sep-Pak Plus C18 cartridge and high-performance liquid chromatography (HPLC), we isolated the

Cucurbitacins 1 and 2 were isolated from the root of Trichosanthes kirilowii by tyrosinase inhibitory activity-guided fractionation. Spectroscopic analysis revealed that compounds 1 and 2 were cucurbitacin D and 23,24-dihydro-cucurbitacin D, respectively. Compounds 1 and 2 effectively inhibited the

From the fresh roots of Trichosanthes kirilowii Maxim. var. japonicum Kitam., the following substances were identified: methyl palmitate, palmitic acid, suberic acid, alpha-spinasterol, stigmast-7-en-3 beta-ol, alpha-spinasterol 3-O-beta-D-glucopyranoside, stigmast-7-en-3 beta-ol

Pancreatic cancer has a poor prognosis with a five-year survival rate of less than 10%. Moreover, chemotherapy is mostly rendered ineffective owing to chemotherapy resistance and cytotoxicity. Therefore, the development of effective therapeutic strategies and novel drugs against pancreatic cancer is

We previously reported that cucurbitacin D isolated from Trichosanthes kirilowii has anti-tumor roles to leukemia cells. However, the effect of cucurbitacin D on immune cells is not fully understood although there is no toxic activity to normal cells. In this study, immunomodulating activities of

A mixture of alpha-spinasterol, stigmast-7-en-3-beta-ol (1) and its 3-O-beta-D-glucopyranoside (2), bryonolic acid (3), 23,24-dihydrocucurbitacin B (4), cucurbitacin B (5), cucurbitacin D (6) were obtained from the fresh roots of Trichosanthes multiloba Miq. (Cucurbitaceae). 1, 2, 4, 5 and 6 were
