Inhibition of Telomerase Activity by Cucurbitacin I in Colon Cancer Cell Line, LS174T

open access: yesProceedings, 2017
Telomerase activity is dependent on the expression level of human telomerase reverse transcriptase (hTERT) in cancer cells. hTERT messenger ribonucleic acid (mRNA) is expressed in more than 85% of cancer cells, but not in normal human somatic cells ...

JSI-124 Induces Cell Cycle Arrest and Regulates the Apoptosis in Glioblastoma Cells

open access: yesBiomedicines, 2023
Cucurbitacin I (JSI-124), derived from Cucurbitaceae, has shown the potential to induce apoptosis and cell cycle arrest in some cancer cells. However, the effect of JSI-124 on glioblastoma multiforme (GBM) cell cycle and apoptosis is still unclear.

New Cytotoxic Cucurbitacins fromWilbrandia ebracteataCogn.

open access: yesPlanta Medica, 2011
Chemical investigation of the roots of Wilbrandia ebracteata Cogn. (Cucurbitaceae) led to the isolation of two new (1- 2) and four known (3- 6) cucurbitacins. Their structures were elucidated by NMR and MS and compared with related compounds. The in vitro cytotoxicity of isolated compounds was evaluated against RD, KB, HCT-8, and A549 cell lines ...
