Description

SK1-I hydrochloride (BML-258 hydrochloride), an analog of sphingosine, is an isozyme-specific competitive SPHK1 inhibitor with a Ki value of 10 µM[1]. SK1-I hydrochloride (BML-258 hydrochloride) has good water solubility. SK1-I hydrochloride (BML-258 hydrochloride) shows no activity at SPHK1 PKCα, PKCδ, PKA, AKT1, ERK1, EGFR, CDK2, IKKβ or CamK2β. SK1-I hydrochloride (BML-258 hydrochloride) enhances autophagy and has antitumor activity[2].

IC50 & Target

Ki: 10 µM (SPHK1)[1]

In Vitro

SK1-I hydrochloride (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[2].
SK1-I hydrochloride (0-20 μM; 12 hours) induces more CASP3 cleavage in HCT116 cells, compared to HCT116 cells lacking TP53, leading to a hallmark of apoptosis[2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Viability Assay[2]

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[2]

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.
In Vivo

Pre-treatment with SK1-I hydrochloride (BML-258 hydrochloride; 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[3].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Male C57BL/6 mice (24 ± 3.5 g) [3]
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).
