体外研究
(In Vitro)

Exposure of the COLO205 cells to Cucurbitacin I significantly decreases cell viability. The anticancer activity of Cucurbitacin I is accomplished by downregulating p-STAT3 and MMP-9 expression[1]. PE-induced cell enlargement and upregulation of ANF and β-MHC are significantly suppressed by pretreatment of the cardiomyocytes with Cucurbitacin I. Notably, Cucurbitacin I also impaires connective tissue growth factor (CTGF) and MAPK signaling, pro-hypertrophic factors, as well as TGF-β/Smad signaling, the important contributing factors to fibrosis[2]. Incubation of the Seax cell line with the Jak/Stat3 inhibitor Cucurbitacin I result in a time- and concentration-dependent decrease of P-Stat3 and Stat3. In freshly isolated Sz cells (n=3), Cucurbitacin I induces a concentration-dependent decrease in Stat3 expression whereas P-Stat3 is undetectable. Finally, incubation of freshly isolated Sz cells (n=4) with 30 μM Cucurbitacin I for 6 hours induces apoptosis in the large majority (73-91%) of tumor cells[3].

体内研究
(In Vivo)

No major side effects are noted throughout the study. It is shown that average tumor volumes at the end of the study are as follows: control, 616 mm3(±130); CQ, 580 mm3(±107); Cucurbitacin I, 346mm3(±79); and combination, 220mm3(±62). The differences in tumor volume between the Cucurbitacin I and control, combination and control, and combination and Cucurbitacin I arms are significant. Furthermore, combination-treated tumors exhibit a significantly lower average tumor weight at study termination than the control. Moreover, there was no effect on the body weights of mice[4].
