HG-7-85-01

HG-7-85-01 (0-1 μM; 24 hours; BCR-ABL-, BCR-ABL-T315I-, Kit-T670I-, PDGFRα-T674M-, and PDGFRα-T674I-expressing cells) treatment leads to G0G1 arrest of BCR-ABL-expressing cells^[1].
HG-7-85-01 (0-1 μM; 72 hours; BCR-ABL-, BCR-ABL-T315I-, Kit-T670I-, PDGFRα-T674M-, and PDGFRα-T674I-expressing cells) treatment also leads to induction of apoptosis of BCR-ABL-expressing cells^[1].
HG-7-85-01 treatment potently and selectively inhibits the proliferation of 32D- and Ba/F3 cells expressing nonmutant BCR-ABL and the BCR-ABL-T315I gatekeeper mutant. HG-7-85-01 shows higher potency against nonmutant BCR-ABL and BCR-ABL-T315I (IC₅₀ = 0.06-0.14 μM)^[1].
HG-7-85-01 inhibits BCR-ABL kinase activity in a concentration-dependent manner, suggesting selective targeting of the BCR-ABL kinase as the mechanism of action of HG-7-85-01^[1].
HG-7-85-01 potently inhibits the proliferation of Ba/F3 cells expressing the Kit-T670I gatekeeper mutation (Ba/F3- Kit-T670I) and Ba/F3 cells expressing TEL/PDGFRβ and no effect on parental Ba/F3 cells. HG-7-85-01 inhibits Kit, PDGFR phosphorylation in a concentration-dependent manner^[1].
The PDGFRα-T674M and PDGFRα-T674I gatekeeper mutant variants are highly responsive to HG-7-85-01 and significant IL-3 rescue^[1].
HG-7-85-01 inhibits the proliferation of Ba/F3 cells transformed with human c-Src (EC₅₀ = 190 nM), T338I Src (EC₅₀ = 290 nM), and T338M Src (EC₅₀ = 150 nM; chicken c-Src numbering). And potently inhibits the proliferation of exon 11 Kit mutant-expressing cells, exon 9 kit mutant-expressing cells are significantly less responsive^[1].
