Haplophytin-A
Based on 1 Customer Validation
Haplophytin-A is a quinoline alkaloid. Haplophytin-A is a potent apoptosis inducer that exerts robust anti-leukemic activity by activating the caspase-8-dependent apoptotic pathway. Haplophytin-A can be used for the research of promyelocytic leukemia.

Haplophytin-A (48 h) induces cytotoxicity in human cancer cell lines, with the highest potency against HL-60 promyelocytic leukemia cells (IC50 = 13.7 μM)[1].
Haplophytin-A (15-50 μM; 0-6 h) induces apoptosis in HL-60 cells, as shown by time- and dose-dependent DNA fragmentation and increased Annexin V-positive cells[1].
Haplophytin-A (50 μM; 0-6 h) activates caspase-8, caspase-9, caspase-3, and cleaves PARP in HL-60 cells[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
-
Cell Line:human promyelocytic leukemia HL-60 cells
-
Concentration:15, 30 and 50 μM
-
Incubation Time:0, 1, 2, 4 and 6 h
-
Result:Caused time- and dose-dependent DNA fragmentation, with ~70% fragmentation observed at 50 μM for 6 h.
Produced a DNA ladder pattern at 4 h with 50 μM.
Increased Annexin V-positive cells to 42.29% after 6 h with 50 μM.
-
Cell Line:human promyelocytic leukemia HL-60 cells
-
Concentration:50 μM
-
Incubation Time:0, 1, 2, 4 and 6 h
-
Result:Activated caspase-8 and -9 at 2 h, and caspase-3 and cleaved PARP at 4 h.
Was blocked from inducing DNA fragmentation at 50 μM for 6 h when co-treated with caspase inhibitors (z-DEVD-fmk, z-IETD-fmk, z-LEHD-fmk, z-VAD-fmk).\n
Induced Fas-FasL interaction at 1 h and FADD-procaspase-8 association at 2 h, forming the Fas-FasL-FADD-caspase-8 DISC complex.
-
Cell Line:human promyelocytic leukemia HL-60 cells
-
Concentration:50 μM; 50 μM (with 5 μM CsA pretreatment for 30 min)
-
Incubation Time:0, 1, 2, 4 and 6 h
-
Result:Reduced cytosolic Bid/Bax and increased mitochondrial Bid/Bax.
Decreased Bcl-2/Bcl-XL levels, reduced Δψₘ (attenuated by CsA), and induced cytochrome c/Smac/DIABLO release to cytosol.
Increased Smac/DIABLO-XIAP interaction and dissociated XIAP from procaspase-9/-3.
