Scoulerine
Scoulerine shows significant cytotoxic effects against both two cancer cell lines (Caco-2 and Hep-G2 cancer cells), with IC50 values 6.44 ± 0.87 and 4.57 ± 0.42, respectively. It shows antiplasmodial activity with IC(50) values of 5.4uM and 3.1uM against the antifolate sensitive and the multidrug resistant P. falciparum strains: TM4/8.2 and K1CB1, respectively.

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to
24 months(2-8C).
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20C. Generally, these will be useable for up to two weeks. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.

The packaging of the product may have turned upside down during transportation, resulting in the natural compounds 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.

Cytotoxicity of Naturally Occurring Isoquinoline Alkaloids of Different Structural Types.[Pubmed:
27534109]
METHODS AND RESULTS:
Forty-six isoquinoline alkaloids, of eleven structural types isolated in our laboratory, have been evaluated for their cytotoxicity against two cancer cell lines (Caco-2 and Hep-G2 cancer cells), as well as against normal human lung fibroblast cells. Only Scoulerine, aromoline, berbamine and parfumidine showed significant cytotoxic effects, but only Scoulerine was active against both Caco-2 and Hep-G2 cells (IC50 values 6.44 ± 0.87 and 4.57 ± 0.42, respectively). Unfortunately, except for parfumidine, the other active alkaloids were also cytotoxic to the normal human lung fibroblast cells.

Antimalarial alkaloids from a Bhutanese traditional medicinal plant Corydalis dubia.[Pubmed:
22796506]
METHODS AND RESULTS:
Corydalis dubia is used in Bhutanese traditional medicine as a febrifuge and for treating infections in the blood, liver and bile which correlate to the signs and symptoms of malarial and microbial infections.A systematic extraction and isolation protocol yielded one new natural product, dubiamine, and seven known isoquinoline alkaloids, Scoulerine, cheilanthifoline, protopine, capnoidine, bicuculline, corydecumbine and hydrastine.
CONCLUSIONS:
Among the four alkaloids tested, Scoulerine showed the best antiplasmodial activity with IC(50) values of 5.4μM and 3.1μM against the antifolate sensitive and the multidrug resistant P. falciparum strains: TM4/8.2 and K1CB1, respectively. None of the alkaloids tested showed significant antimicrobial or cytotoxicity activities.
