Raptinal
Based on 10 publication(s) in Google Scholar
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.

Caspase 3 |
H. pylori infection-induced apoptosis resistance in gastric epithelial cells triggered by Raptinal[1].
Treatment with 10 μM of Raptinal for 2 h induces the cleavage of pro-caspase-3 into it’s active form in human gastric cancer cell lines AGS, MKN28, MKN45[1].
Raptinal initiates intrinsic pathway caspase-dependent apoptosis within minutes in multiple cell lines. Raptinal induces death against various cancer and non-cancerous cell lines with 24 hour IC50 values between 0.7-3.4 μM, indicating activity across a wide variety of cell lines[2].

-
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.
-
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.
Raptinal (20 mg/kg; administered intraperitoneally; once daily for 3 consecutive days for B16-F10 and 4 consecutive days for 4T1 models) exerts anticancer activity in vivo[2].
C57BL/6 mice are administered intravenous Raptinal across a range of dosages as a one-time injection. When administered intravenously at a dosage of 37.5 mg/kg, the peak plasma concentration and elimination half-life of Raptinal are 54.4±0.9 μg/mL and 92.1±5.8 minutes, respectively. Single-dose intravenous Raptinal is well tolerated across a wide dose range (15-60 mg/kg) and does not cause hematologic toxicity as assessed 7 days post-administration[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:C57BL/6 and BALB/c female mice (6-8 weeks old) bearing the B16-F10 model or 4T1 models[2]
-
Dosage: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.

Annexin V staining assays to quantify the number of apoptotic cells following expression of mARG vectors. HEK293T cells transfected with pgvpA-IRES-mCherry with the start codon removed in front of gvpA were used to establish a baseline (Not Treated). A subset of these cells was treated with Raptinal (10 μM; 18 h) to induce apoptosis (Raptinal Treated). Other cell populations were transfected solely with a fully functional pgvpA-IRES-mCherry (gvpA-IRES-mCherry), the two-vector system (Two-vector), or the ACC/ACC SEMPER mARG plasmid (SEMPER mARG).
