生物活性

SK1-I (BML-258), an analog of sphingosine, is an isozyme-specific competitive SPHK1 inhibitor with a Ki value of 10 µM. SK1-I shows no activity at SPHK1 PKCα, PKCδ, PKA, AKT1, ERK1, EGFR, CDK2, IKKβ or CamK2β. SK1-I enhances autophagy and has antitumor activity.

体外研究

SK1-I (0-10 μM; 24 hours) attenuates cancer cell growth and survival in a TP53-dependent manner in HCT116 cells and HCT116 cells bearing TP53 null cancer.
SK1-I (0-20 μM; 12 hours) induces more CASP3 cleavage in HCT116 cells, compared to HCT116 cells lacking TP53, leading to a hallmark of apoptosis.

Cell Viability Assay

Cell Line: HCT116 cells and HCT116 cells bearing TP53 null cancer
Concentration: 0 µM, 2.5 µM, 5 µM, 7.5 µM, 10 µM
Incubation Time: 24 hours
Result: Decreased cancer cell growth and survival.

Western Blot Analysis

Cell Line: HCT116 cells and HCT116 cells bearing TP53 null cancer
Concentration: 0 µM, 5 µM, 10 µM, 20 µM
Incubation Time: 12 hours
Result: Induced more CASP3 cleavage in HCT116 cells, compared to HCT116 cells lacking TP53.
体内研究

Pre-treatment with SK1-I (BML-258; intraperitoneal (i.p.) injection; once; 24 hours prior to baseline mean arterial blood pressure (MAP) measurement; 75 mg/kg) before anandamide (i.v. injection; two doses; 1 and 10 mg/kg) significantly decreases the hypotensive response.

Animal Model: Male C57BL/6 mice (24 ± 3.5 g)
Dosage: 75 mg/kg
Administration: Intraperitoneal (i.p.) injection; once; 24 hours prior to baseline MAP measurement
Result: Significantly lowered baseline mean arterial blood pressure (MAP).
