HM-279
HM-279 is a potent and orally active ALK5 inhibitor with an IC50 of 4.7 nM. HM-279 shows cross-reactivity with ALK7 (IC50 = 6.8 nM), but HM-279 has fair to good selectivity against other TGF-β receptor family kinases, with 4.5-693-fold selectivity. HM-279 demonstrates antitumor activity in vivo through CD8+ T cell immunity. HM-279 can be used for the research of colon cancer.

HM-279 exhibits an excellent kinase selectivity and inhibits only 9 kinases: AurA, BUB1/BUB3, FLT4, KDR, NuaK1, PDGFRα, PDGFRβ, QIK, and MST1[1].
HM-279 has very weak antiproliferative activity against CT26 cells (IC50 = 15 μM).
HM-279 (1.5 h; 1-300 nM) strongly inhibits the phosphorylation of Smad3 in A549 cells (IC50 = 21.6 nM)[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

HM-279 (30 mg/kg; p.o.; 5days ON/2days OFF; for 15 days) loses its antitumor activity in both female BALB/c Slc-nu/nu mice and female BALB/cCrSlc mice handled with the anti-CD8 antibody (5 mg/kg; i.p.; twice a week), confirming the involvement of CD8+ T cells in the antitumor immune response elicited by HM-279[1].

-
Animal Model:Female BALB/c Slc-nu/nu mice (7 weeks old) were inoculated subcutaneously in the flank with CT26.WT cells (1 × 106 cells) to establish a xenograft model[1].
-
Dosage:30 mg/kg
-
Administration:p.o.; 5 days ON/2 days OFF; for 15 days
-
Result:Did not have antitumor activity.
-
Animal Model:Female BALB/cCrSlc mice (7 weeks old) were handled with the anti-CD8 antibody (5 mg/kg; i.p.; twice a week) or isotype control antibody (5 mg/kg; i.p.; twice a week) to establish a CD8-depletion model. Then the mice were inoculated subcutaneously in the flank with CT26.WT cells (1 × 106 cells)[1].
-
Dosage:30 mg/kg
-
Administration:p.o.; 5 days ON/2 days OFF; for 15 days
-
Result:Did not have antitumor activity in the isotype combination group and the anti-CD8 combination group.
-
Animal Model:Female BALB/cCrSlc mice (7 weeks old) were inoculated subcutaneously in the flank with CT26.WT cells (1 × 106 cells) to establish a syngeneic model[1].
-
Dosage:30 mg/kg; 30 mg/kg plus anti-PD-1 antibody (10 mg/kg; i.p.; BIW)
-
Administration:p.o.; 5 days ON/2 days OFF; for 20 days
-
Result:Showed partial antitumor activity with TGI of 60% without body weight loss in orally administration.
When used in combination with anti-PD-1 antibody, the TGI was 89%.
