(Rac)-GSK-3484862
Based on 1 Customer Validation
(Rac)-GSK-3484862 (GSK3482364) is a selective, orally active, reversible DNA methyltransferase 1 (DNMT1) inhibitor with an IC50 of 0.4 μM. (Rac)-GSK-3484862 inhibits the methyltransferase activity of DNMT1 independently of DNA incorporation, reduces global DNA methylation levels, and relieves the transcriptional repression of HBG1 and HBG2 genes. (Rac)-GSK-3484862 increases fetal hemoglobin levels and the proportion of red blood cells expressing fetal hemoglobin in erythroid progenitor cells and a transgenic mouse model of sickle cell disease. (Rac)-GSK-3484862 can be used in studies related to sickle cell disease.

DNMT1 0.4 μM (IC50) |
(Rac)-GSK-3484862 (0.01-10 μM; 5 days) induces dose-dependent genome-wide and HBG1/HBG2 promoter hypomethylation, upregulation of HBG1/HBG2 mRNA, and HbF protein expression in human bone marrow-derived EPCs, with an IC50 of 0.24 μM for genome-wide DNA hypomethylation[1].
(Rac)-GSK-3484862 (1.0 μM; 18 days) increases the number of HbF-positive cells to more than 4-fold the original level in human bone marrow CD34+ cells induced to differentiate into reticulocytes over 18 days, without affecting the maturation of erythroid cells[1].
(Rac)-GSK-3484862 reduces the methylation activity of DNMT1, reactivates the globin genes HBG1 and HBG2, upregulates the expression of HbF, and increases the proportion of HbF-containing red blood cells in an unspecified in vitro cell system[2].

(Rac)-GSK-3484862 reduces DNMT1 activity, reactivates globin genes, and increases HbF expression and HbF-containing erythrocytes in transgenic murine models of sickle cell disease[2].

Animal Model:B6;129-HBAtm1(HBA)Tow/HBBtm2(HBG1,HBB)Tow/J (male and female, 6-8 weeks old, sickle cell disease transgenic model)[1]
-
Dosage:3.7-100 mg/kg (12-day dosing); 3.7-100 mg/kg (2-week intermittent dosing); 3.7-100 mg/kg (4-week intermittent dosing)
-
Administration:p.o.; b.i.d. on weekdays; 12 days, 2 weeks, or 4 weeks
-
Result:Increased HbF levels to 3.3% (from vehicle 0.4%) at 10 mg/kg.
Increased F-cells to 22.7% (from vehicle 4.3%) at 10 mg/kg.
Increased HbF 10.3-fold relative to vehicle (to 5.3%) at 50 mg/kg.
Increased F-cells 8.4-fold relative to vehicle (to 35.5%) at 50 mg/kg.
Increased HbF dose-dependently up to 9-fold versus vehicle across 3.7-100 mg/kg doses, reaching a plateau at 33.3 mg/kg and 100 mg/kg.
Reduced -53 bp HBG1 promoter methylation by a maximum 25% at 33.3 mg/kg in bone marrow.
Increased HBG1 mRNA levels up to 29-fold versus vehicle across all dose groups in bone marrow.
Maintained unchanged HBB and HBA1 mRNA levels in bone marrow.
Showed no significant changes in peripheral blood cell counts (RBC, platelets, neutrophils, lymphocytes, monocytes) at any dose compared to vehicle.
Showed no abnormalities in cellularity or hematopoietic cell composition in sternal bone marrow histology at 100 mg/kg.
Produced robust HbF induction with no body weight changes during intermittent dosing (b.i.d. on 3 weekdays) for 2 or 4 weeks.
Showed a small non-significant increase in HbF with 4-week intermittent dosing compared to 2-week dosing.
