Applications

Angelicin displays a wide variety of potent and interesting biological activities. These include antifungal activities, inducing S-phase delay in the rad 14Δmutant, inhibition of mutagenesis of 2-amino-3-methylimidazo[4,5-f]quinoloine, inhibitory effects on the biotransformation of aflatoxin B1 to aflatoxin B1-8,9-epoxide, and inhibition of inducible nitric oxide synthase.


Angelicin is structurally related to psoralens, a well-known chemical class of photosensitizers used for its antiproliferative activity in treatment of different skin diseases. To verify the activity of angelicin, we employed human SH-SY5Y neuroblastoma cells to investigate its cytotoxicity, although its mechanism of action has not yet been fully elucidated. Here, we examined the cellular cytotoxicity of angelicin by cell viability assay, DNA fragmentation by DNA ladder assay, and activation of caspases and Bcl-2 family proteins by western blot analyses. The results of our investigation suggest that angelicin increased cellular cytotoxicity in a dose- and time-dependent manner with IC(50) of 49.56 μM at 48 h of incubation. In addition, angelicin dose-dependently downregulated the expression of anti-apoptotic proteins including Bcl-2, Bcl-xL, and Mcl-1 suggesting the involvement of the intrinsic mitochondria-mediated apoptotic pathway which did not participate in Fas/FasL-induced caspase-8-mediated extrinsic, MAP kinases, and PI3K/AKT/GSK-3β pathway. Furthermore, we clarified the dose-dependent upregulation of caspase-9 and caspase-3 which indicated that angelicin-induced apoptosis is mediated primarily through the intrinsic caspase-mediated pathway. In particular, the caspase-3 inhibitor, DEVD-fmk, induced a reduction in angelicin-induced cytotoxicity which confirmed that the intrinsic caspase-dependent pathway during this apoptosis which did not prevent cytotoxicity using MAP kinases and GSK-3 inhibitor. Taken together, our data shows that angelicin is an effective apoptosis-inducing natural compound of human SH-SY5Y neuroblastoma cells which suggests that this compound may have a role in future therapies for human neuroblastoma cancer.

After Receiving
The packaging of the product may have turned upside down during transportation, resulting in the product adhering to the neck or cap of the vial. take the vial out of its packaging and gently shake to let the compounds fall to the bottom of the vial. for liquid products, centrifuge at 200-500 RPM to gather the liquid at the bottom of the vial. try to avoid loss or contamination during handling.
