Summary
SK1-I hydrochloride (BML-258 hydrochloride), an analog of sphingosine, is an isozyme-specific competitive SPHK1 inhibitor with a K i value of 10 µM [1] . 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 [2] .
IC50 & Target

SphK1

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]
.

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] .
