Breakthroughs in cancer management result from the development of drugs that can be used for early diagnosis and effective treatment. Surgery, chemotherapy, radiotherapy and hormone therapy are the main anticancer therapies. However, traditional cancer chemotherapy is associated with serious
Although gemcitabine is the standard chemotherapy treatment for advanced pancreatic cancer, its benefits are quite limited due to prevalent chemoresistance, and the mechanism underlying gemcitabine chemoresistance remains unclear. Currently, Nrf2 has been deemed as a significant contributor to
Brusatol, isolated from brucea, has been proved to exhibit anticancer influence on various kind of human malignancies. However, the role that brusatol plays in pancreatic cancer is seldom known by the public. Through researches brusatol was proved to inhibit growth and induce apoptosis in both
Pancreatic cancer is highly resistant to chemotherapeutic agents and is known to have a poor prognosis. The development of new therapeutic entities is badly needed for this deadly malignancy. In this study, we demonstrated for the first time that brusatol, a natural quassinoid isolated from a
Colorectal cancer (CRC) is a common and life‑threatening type of malignant cancer, which is associated with a high mortality rate. Cisplatin (CDDP) is a commonly used chemotherapy drug with significant side effects. Brusatol (BR) is one of the principal chemical compounds isolated from the Chinese
Brusatol, a natural quassinoid isolated from a traditional Chinese herbal medicine known as Bruceae Fructus, has recently been reported to possess powerful cytotoxic effects against various cancer cell lines, highlighting its potential as an anti-cancer drug. However, the precise molecular
Nrf2 is a transcription factor that regulates cellular stress response and irinotecan-metabolising pathways. Its aberrant activity has been reported in a number of cancers, although relatively few studies have explored a role for Nrf2 in colorectal cancer (CRC). This study assessed the expression of
Background
Natural products from herbal medicines have long been investigated for their potentials as
cancer therapeutics. Besides the development of several herbal medicine-derived anti-
cancer agents, such as paclitaxel, vincristine and podophyllotoxin, many recent laboratory
The HER2-targeting antibody trastuzumab has shown effectiveness in treating HER2-positive breast and gastric cancers; however, its responses are limited. Currently, Nrf2 has been deemed as a key transcription factor in promoting cancer progression and resistance by crosstalk with other proliferative

The KEAP1/Nrf2 pathway senses and responds to changes in intracellular oxidative stress. Mutations that result in constitutive activation of Nrf2 are present in several human tumors, especially non-small cell lung cancer. Therefore, compounds that inhibit Nrf2 activity might be beneficial in
Purpose: Brusatol, a natural quassinoid that is isolated from a traditional Chinese herbal medicine known as Bruceae Fructus, possesses biological activity in various types of human cancers, but its effects in nasopharyngeal carcinoma (NPC) have not been reported.
Background: Tumor progression and tumor response to anticancer therapies may be affected by activation of oncogenic pathways such as the antioxidant one induced by NRF2 (nuclear factor erythroid 2-related factor 2) transcription factor
The quassinoids (brusatol, bruceantin, bisbrusatolyl esters, and bisbruceantinyl esters of succinic and malonic acids) were observed not to be universal protein synthesis inhibitors. Rather, they were selective for both the types of cancers, e.g., P-388 lymphocytic leukemia, Ehrlich and hepatoma
A series of brusatol, bisbrusatol, and bruceantin esters were examined for their ability to inhibit protein synthesis in P-388 lymphocytic leukemia cells. Compounds which produced high T/C % values (170-272) resulted in ID50 of 5.4-15.5 microM for inhibition of whole cell protein synthesis, ID50 of
