Raptinal

Research use only, not for human use.

Raptinal activates caspase-3 directly and initiates intrinsic caspase-dependent apoptosis pathway in multiple cell lines.

Raptinal, a agent that directly activates caspase-3, initiates intrinsic pathway caspase-dependent apoptosis. Raptinal is able to rapidly induce cancer cell death by directly activating the effector caspase-3, bypassing the activation of initiator caspase-8 and caspase-9.

Cell Viability Assay Cell Line:Human Lymphoma U-937, SKW 6.4, or Jurkat cell lines Concentration:0.7-3.4 μM Incubation Time:24 hours Result:The IC50?values of Raptinal against U-937, SKW 6.4, or Jurkat cell lines were 1.1±0.1, 0.7±0.3, 2.7±0.9 μM, respectively.Western Blot Analysis Cell Line:Human gastric cancer cell lines AGS, MKN28, MKN45 Concentration:10?μM Incubation Time:2 hours Result:Induced apoptosis by activating caspase-3 within 30?min at a concentration of 10?μM. Treatment with 10?μM of Raptinal for 2?h induced the cleavage of pro-caspase-3 into it’s active form in all three cell lines.?

Animal Model:C57BL/6 and BALB/c female mice (6-8 weeks old) bearing the B16-F10 model or 4T1 modelsDosage:20 mg/kg Administration:Administered intraperitoneally; once daily for 3 consecutive days for B16-F10 and 4 consecutive days for 4T1 models Result:Retard tumor volume and tumor mass by 60% relative to controls in the B16-F10 model.Similar efficacy was observed for the 4T1 murine breast cancer tumor model with 50% growth inhibition after treatment.?
