应用
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.
生化/生理作用
SKI II is a selective non-lipid sphingosine kinase (SK) inhibitor. IC50 = 0.5 μM; does not act at ATP-binding site. Displays no inhibition of ERK2, PI 3-kinase, or PKCα at concentrations up to 60 μM. Induces apoptosis and inhibits proliferation in several other tumor cell lines in vitro (IC50 = 0.9-4.6 μM).
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).

Recent studies suggested an important contribution of sphingosine-1-phospate (S1P) signaling via its specific receptors (S1PRs) in the production of pro-inflammatory mediators such as Interleukin (IL)-1β in cancer and inflammation. In an inflammation-driven cancer setting, we previously reported that myeloid S1PR1

The non-dioxin-like environmental toxicant 2,2',4,4',5,5'-hexachlorobiphenyl (PCB153), member of a group of persistent organic pollutants wide-spread throughout the environment, reduces gap junction intercellular communication (GJIC), an event possibly associated with tumor promotion. Since very few studies have investigated the signaling effectors
