goyazensolide/悪性腫瘍

As part of the screening program for anticancer agents from natural sources, the sesquiterpene lactone goyazensolide (GZL) was identified as a potent NF-κB inhibitor. The hollow-fiber assay was used to evaluate the anti-tumor efficacy of GZL in vivo. The mechanistic effects of GZL were evaluated in

OBJECTIVE Cucurbitacin D and goyazensolide, 2 plant-derived natural compounds, possess potent growth-inhibitory activity in schwannoma and meningioma cells. BACKGROUND Currently, no FDA-approved drugs are available for neurofibromatosis type 2 (NF2)-associated schwannomas and meningiomas. Selected

Bioassay-directed fractionation of an antiproliferative ethanol extract of the leaves and twigs of Piptocoma antillana (Asteraceae) afforded two new goyazensolide-type sesquiterpene lactones named 5-O-methyl-5-epiisogoyazensolide (1) and 15-O-methylgoyazensolide (2), together with the known

c-myb is a proto-oncogene encoding a transcription factor which is highly expressed in hematopoietic progenitor cells. It regulates the expression of genes important for lineage determination, cell proliferation, and differentiation. Deregulation of c-myb expression is known to be involved in the

This work reports for the first time the production a furanoheliangolide (goyazensolide) by plant cell culture. Monitoring of the goyazensolide metabolism revealed that the maximum production occurred during the lag phase of the Lychnophora ericoides callus culture. The antiproliferative activity of

Gliomas are responsible for more than 60% of all primary brain tumors. Glioblastoma multiforme (GBM), a grade IV tumor (WHO), is one of the most frequent and malignant gliomas. Despite two decades of advances in the discovery of new markers for GBM, the chemotherapy of choice falls to temozolomide
