Description

General description

A cell permeable, orally bioavailable thiazolidine-2,4-dione derivative that acts as a selective, sphingosine competitive inhibitor of spingosine Kinase -2 (SphK2; IC₅₀ = 4.3 µM; Ki = 6.4 µM), but does not affect the activities of sphingosine kinase-1, ceremide kinase, and ceramide synthase even at high concentration (~10 micro;M). Shown to inhibit the growth of U937 human leukemic monocyte lymphoma cells by inducing apoptosis and inhibiting the phosphorylation of ERK and Akt. Blocks the growth of U937 cells in nude mice and inhibits the growth of JC tumor cells in BALB/c mice without any apparent toxicity.
