| In Vitro | 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[2]. 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[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 (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). |
