Longilactone

Longilactone is a quassinoid diterpenoid isolated from the roots of Eurycoma longifolia. Longilactone induces apoptosis in MCF-7 cells via the extrinsic caspase pathway, activating the cleavage of caspase-8, caspase-7 and PARP. Longilactone can be used in research related to breast cancer and human lung cancer.

In Vitro

Longilactone (0.32-20 µg/mL; 72 h) potently inhibits the viability of human breast cancer MCF-7 cells, with an IC₅₀ of 0.53 µg/mL after 72 h of treatment^[1].
Longilactone (compound 36) exhibits cytotoxic activity against human lung cancer (A-549) cells with an ED₅₀ value of 4.6 μg/mL; it also shows cytotoxic activity against human breast cancer (MCF-7) cells with an ED₅₀ value of 6.1 μg/mL^[3].
Longilactone (5 µg/mL; 12-72 h) induces time-dependent apoptosis in human breast cancer MCF-7 cells^[1].
Longilactone (5 µg/mL; 72 h) induces apoptosis in human breast cancer MCF-7 cells^[1].
Longilactone (5 µg/mL; 0-72 h) activates caspase-8 in a time-dependent manner in human breast cancer MCF-7 cells, but has no effect on the activity of caspase-9^[1].
Longilactone (5 µg/mL; 0-72 h) upregulates the levels of activated caspase-8, activated caspase-7 and cleaved PARP in a time-dependent manner, activates the extrinsic apoptotic pathway in human breast cancer MCF-7 cells, and does not alter the expression of Bax and Bcl-2 or activate caspase-9^[1].
Longilactone exhibits no significant anti-HIV activity in H9 lymphocytes^[3].

Cell Cytotoxicity Assay^[1]

Cell Line:

human breast cancer MCF-7 cells
Concentration:

0.32, 0.16, 0.8, 4, 20 µg/mL
Incubation Time:

72 h
Result:

Exerted strong cytotoxic activity on MCF-7 cells, with an IC₅₀ of 0.53 µg/mL.

Apoptosis Analysis^[1]

Cell Line:

human breast cancer MCF-7 cells
Concentration:

5 µg/mL
Incubation Time:

12, 24, 48, 72 h
Result:

Induced typical apoptotic nuclear morphology changes including fragmentation, hypercondensation, and shrinkage after 48 h incubation.
Increased the percentage of apoptotic MCF-7 cells in a time-dependent manner, reaching 74.3% after 72 h.

Western Blot Analysis^[1]

Cell Line:

human breast cancer MCF-7 cells
Concentration:

5 µg/mL
Incubation Time:

12, 24, 48, 72 h
Result:

Increased levels of pro-caspase-8 (55 kDa), active caspase-8 (29 kDa), active caspase-7 (20 kDa), and cleaved poly (ADP-ribose) polymerase (PARP, 89 kDa) in a time-dependent manner.
Did not alter basal levels of Bax (20 kDa) and Bcl-2 (26 kDa), and active caspase-9 was not detected.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
