SP2509
(Synonyms: HCI-2509, LSD1 Inhibitor VII) 目录号 : GC14631
A reversible inhibitor of LSD1
Cas No.:1423715-09-6
Sample solution is provided at 25 µL, 10mM.
SP2509 is a novel Lysine specific demethylase 1 (LSD1) antagonist (IC50 = 13nM) with no effect on MAO-A and MAO-B. [1]
LSD1 demethylates mono-/di-methylated lysine 4 on histone H3. High expression of LSD1 is associated with poor prognosis in cancer. [2]
In cultured human AML cells, SP2590 inhibited LSD1 activity, deplete colony growth and elicit apoptosis. SP2590 also inhibited the LSD1 binding to CoREST, increase promoter-specific H3K4Me3 and induces p53, p21 and C/EBPα in AML cells. Moreover, SP2590 promotes differentiated of cultured and primary AML cell. [1]
In mice carrying AML xenografts, SP2590 treatment alone significantly improved the survival of mice and co-treatment with an-HDAC inhibitor (HDI) panobinostat (PS) exhibited superior in vivo activity. [1]

SP2509 activity assay |
Test compounds were diluted to 20 × the desired test concentration in 100% dimethyl sulfoxide and 2.5 μl of the diluted drug sample was added to a black 384-well plate. The LSD1 enzyme stock was diluted 17-fold with assay buffer and 40 μl of the diluted LSD1 enzyme was added to the appropriate wells. Substrate, consisting of horseradish peroxidase, dimethyl K4 peptide corresponding to the first 21 amino acids of the N-terminal tail of histone H3, and 10-acetyl-3,7-dihydroxyphenoxazine was then added to wells. Resorufin was analyzed on a plate reader with an excitation wavelength of 530 nm and an emission wavelength of 595 nm. |

Applications |
SP2509 inhibits LSD1 activity, reduces colony growth and induces apoptosis of cultured AML cells. SP2509 treatment also inhibits the association of LSD1 with CoREST, increases promoter-specific H3K4Me3 and induces p53, p21 and C/EBPα in AML cells. Furthermore, treatment with SP2509 induces differentiation of cultured and primary AML cells |

Animal models |
NOD/SCID mice |
|
Dosage form |
25 mg/kg SP2509 administered twice per week (Tuesday and Thursday) intraperitoneally for 3 weeks |
|
Applications |
Treatment with either SP2509 improves the median survival of the mice infused with OCI-AML3 cells (37 and 36.5 days, respectively, versus 19.5 days for vehicle control). Notably, combined treatment with panobinostat and SP2509 further improves the median survival of the mice (44.5 days), as compared with treatment with SP2509 or panobinostat alone (P<0.01). |
|
Other notes |
Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal. |
