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 (SPHK/SK) 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.

S7174

Opaganib (ABC294640)

Opaganib (ABC294640) is an orally bioavailable and selective sphingosine kinase-2 (SphK2) inhibitor with IC50 of approximately 60 μM. Phase 1/2.

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.
