PF15
PF15 is an orally active FLT3-ITD PROTAC degrader with a DC50 of 76.7 nM and an IC50 of 36 nM against FLT3-ITD. PF15 induces FLT3-ITD protein degradation, thereby downregulating its phosphorylation level. PF15 inhibits the proliferation of FLT3-ITD-positive cells and reduces the phosphorylation level of STAT5, a downstream molecule of FLT3-ITD. PF15 exhibits efficacy in in vivo xenograft models of acute myeloid leukemia and prolongs survival. PF15 can be used for the research of acute myeloid leukemia.

PF15 potently and selectively inhibits FLT3 kinase with an IC50 of 36 nM, and its inhibitory potency against c-Kit kinase is over 35-fold lower; it exhibits high selectivity for FLT3 among a panel of 93 tumor-related kinases[1].
PF15 (1-2000 nM; 1-24 h) induces proteasome-dependent degradation of FLT3 protein in BaF3-FLT3-ITD cells, with a DC50 of 76.7 nM, and prolonged incubation achieves complete degradation of the protein[1].
PF15 (10-1000 nM; 2 h) upregulates FLT3 mRNA levels in BaF3-FLT3-ITD cells at low concentrations (10 nM, 30 nM)[1].
PF15 (72 h) potently inhibits the proliferation of MV4-11 FLT3-ITD-positive AML cells with an IC50 of 4.83 nM; potently inhibits the proliferation of Molm-13 FLT3-ITD-positive AML cells with an IC50 of 4.01 nM; potently inhibits the proliferation of BaF3-FLT3-ITD transformed cells with an IC50 of 7.85 nM; inhibits the proliferation of drug-resistant BaF3-FLT3-ITD-D835V transformed cells with an IC50 of 120.1 nM; inhibits the proliferation of drug-resistant BaF3-FLT3-ITD-F691L transformed cells with an IC50 of 116.6 nM; and exhibits only extremely low antiproliferative activity against FLT3 wild-type cancer cells (THP-1, K562, Daudi, HEL, Jurkat, RS4;11)[1].
PF15 (10-1000 nM; 6 h) downregulates the phosphorylation levels of FLT3 and STAT5 in BaF3-FLT3-ITD, BaF3-FLT3-ITD-D835V, and BaF3-FLT3-ITD-F691L cells at a concentration of 100 nM after 6 h of treatment, whereas a higher concentration is required for FLT3 degradation[1].
