Application
Human cisplatin-resistant gastric cancer cell line was treated with SKI-II to study the mechanism of reversion of multidrug resistance.1
SKI II has been used to study the regulatory mechanism and signaling pathway induced by SKI II in inhibiting tumor growth.
Biochem/physiol Actions
Sphingosine kinase (SK) plays a pivotal role in regulating tumor growth and SK can act as an oncogene. Expression of SK RNA is significantly elevated in a variety of solid tumors, compared with normal tissue from the same patient. A number of novel inhibitors of human SK were identified, and several representative compounds were characterized in detail. These compounds demonstrated activity at sub- to micromolar concentrations, making them more potent than any other reported SK inhibitor, and were selective toward SK compared with a panel of human lipid and protein kinases. Kinetic studies revealed that the compounds were not competitive inhibitors of the ATP-binding site of SK. 4-[4-(4-chloro-phenyl)-thiazol-2-ylamino]-phenol (SKI-II) inhibitor is orally bioavailable, detected in the blood for at least 8 h, and showed a significant inhibition of tumor growth in mice with IC50 = 0.5 μM; SKI II does not act at ATP-binding site. Displays no inhibition of ERK2, PI 3-kinase, or PKCa at concentrations up to 60 μM.SKI II induces apoptosis and inhibits proliferation in several other tumor cell lines in vitro (IC50 = 0.9-4.6 μM).

Targeting the type 1 insulin-like growth factor receptor (IGF1R) in breast cancer remains an ongoing clinical challenge. Oncogenic IGF1R-signaling occurs via activation of PI3K/AKT/MAPK downstream mediators which regulate cell proliferation and protein synthesis. To further understand IGF1R signaling we have

Previously, we found that exposure to a 50-Hz magnetic field (MF) could induce human amniotic epithelial (FL) cell proliferation and sphingosine kinase 1 (SK1) activation, but the mechanism was not clearly understood. In the present study, the possible signaling pathways
