Chemico-biological interactions, 221, 13-23 (2014-08-12)
Honokiol, an active constituent of oriental medicinal herb Magnolia officinalis, caused Ca(2+) mobilization and apoptosis in different cancer cells. In vivo, honokiol crossed the blood-brain or -cerebrospinal fluid barrier, suggesting that it may be an effective drug for the treatment...

Journal of cellular biochemistry, 115(11), 1888-1899 (2014-06-07)
Honokiol is a small biphenolic compound, which exerts antitumor activities; however, the precise mechanism of honokiol-induced apoptosis in the human colorectal cancer cells remains unclear. Here, we show that survivin and p53 display the opposite role on the regulation of...
Eun-Ryeong Hahm et al.
The Prostate, 74(4), 408-420 (2013-12-18)
We have shown previously that honokiol (HNK), a bioactive component of the medicinal plant Magnolia officinalis, inhibits growth of human prostate cancer cells in vitro and in vivo. However, the effect of HNK on androgen receptor (AR) signaling has not...

Current molecular medicine, 12(10), 1244-1252 (2012-07-28)
Honokiol (3',5-di-(2-propenyl)-1,1'-biphenyl-2,4'-diol) is a bioactive natural product derived from Magnolia spp. Recent studies have demonstrated anti-inflammatory, anti-angiogenic, anti-oxidative and anticancer properties of honokiol in vitro and in preclinical models. Honokiol targets multiple signaling pathways including nuclear factor kappa B (NF-κB)...

Die Pharmazie, 67(10), 811-816 (2012-11-10)
Honokiol is a small-molecule pharmacologically active component which has various medicinal applications. Increasing interest is paid on its multifunctional anti-tumor effects including inducing tumor cell death, anti-angiogenesis, anti-migration and anti-multiple drug resistance. We addressed a brief summary of the anti-tumor...
