SK1-I (BML-258), an analog of sphingosine, is an isozyme-specific competitive SPHK1 inhibitor with a Ki value of 10 μM[1]. 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[2]. | [in vivo]
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[3]. | 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). |
