SKI II

SKI II (SphK-I2) is a highly selective and non ATP-competitive sphingosine kinase (SphK) inhibitor with IC50 of 0.5 μM, while exhibiting no inhibitory action on other kinases including PI3K, PKCα and ERK2.

S7177

PF-543

PF-543, a novel sphingosine-competitive inhibitor of SphK1, inhibits SphK1 with IC50 and Ki of 2.0 nM and 3.6 nM, exhibits >100-fold selectivity over the SphK2 isoform. PF-543 induces apoptosis, necrosis, and autophagy.

S0817

SKI-V

SKI V is a noncompetitive and potent inhibitor of non-lipid sphingosine kinase with IC50 of 2 μM for GST-hSK. SKI-V also inhibits PI3K with IC50 of 6 μM for hPI3k. SKI-V decreases formation of the mitogenic second messenger sphingosine-1-phosphate (S1P) and induces apoptosis with antitumor activity.

S5989New

SKI-178

SKI-178 is a potent inhibitors of sphingosine kinase-1 (SphK1) and SphK2 with IC50 values ranging from ∼500 nM to ∼1 μM depending on AML cell lines.

S6512

Defensamide (MHP)

Defensamide (MHP) is an activator of sphingosine kinase (SPHK1). It can modulate the innate epidermal immune response by potentiating SPHK1 activity and inducing cAMP production.
