SphK1 Inhibitors (8):

Cat. No. Product Name Effect Purity
  • HY-15425A
    PF-543 Citrate
    Inhibitor 98.35%
    PF-543 Citrate (Sphingosine Kinase 1 Inhibitor II Citrate) is a potent, selective, reversible and sphingosine-competitive SPHK1 inhibitor with an IC50 of 2 nM and a Ki of 3.6 nM. PF-543 Citrate is >100-fold selectivity for SPHK1 over SPHK2. PF-543 Citrate is an effective potent inhibitor of sphingosine 1-phosphate (S1P) formation in whole blood with an IC50 of 26.7 nM. PF-543 Citrate induces apoptosis, necrosis, and autophagy.
  • HY-12892
    Inhibitor 98.05%
    SKI-178 is a potent sphingosine kinase-1 (SphK1) and SphK2 inhibitor. SKI-178 is cytotoxic at IC50 concentrations ranging from 1.8 to 0.1 μM in both agent sensitive and multi-agent resistant cancer cell lines (i.e., MTR3, NCI-ADR and HL60/VCR cells). SKI-178 induces apoptosis in a CDK1-dependent manner in human acute myeloid leukemia cell lines.
  • HY-119016A
    SK1-​I hydrochloride
    Inhibitor 99.49%
    SK1-I hydrochloride (BML-258 hydrochloride), an analog of sphingosine, is an isozyme-specific competitive SPHK1 inhibitor with a Ki value of 10 µM. SK1-I hydrochloride shows no activity at SPHK1 PKCα, PKCδ, PKA, AKT1, ERK1, EGFR, CDK2, IKKβ or CamK2β. SK1-I hydrochloride enhances autophagy and has antitumor activity.
  • HY-147282
    Inhibitor 99.00%
    Amgen-23 (compound 23) is a potent sphingosine kinases (SPHK) inhibitor with IC50 values of 20 nM and 1.6 μM for SPHK1 and SPHK2, respectively. Amgen-23 can be used for researching anticancer.
  • HY-150615
    SphK1-IN-2 is a potent, selective SphK1 inhibitor with IC50 values of 19.81 nM and >10 μM for SphK1 and SphK2, respectively. SphK1-IN-2 exhibits anti-proliferative activities and induces cell cycle arrest and apoptosis. SphK1-IN-2 can be used for cancer research.
  • HY-148707
    SphK1&2-IN-1 is a SphK inhibitor targeting to SphK1 and SphK2. SphK1&2-IN-1 has thermal stability.
  • HY-143296
    SphK1-IN-1 (compound 48) is a SphK1 inhibitor with effective antitumor activity. SphK1-IN-1 inhibits SphK1 ATPase with an IC50 value of 4.02 μM. SphK1-IN-1 can be used for the research of cancer.
  • HY-148262
    SphK1-IN-3 is an effective sphingosine kinase-1 (SphK1) inhibitor. SphK1-IN-3 inhibits SphK1 kinase activity with an IC50 value of 2.48 μM. SphK1-IN-3 can be used for the research of many diseases such as cancer, rheumatoid arthritis, diabetes, asthma, and pulmonary fibrosis.
