flt3 in 6

FLT3-IN-6 is a potent and selective inhibitor of FLT3-ITD [FLT3 mutation], with an IC50 of 1.336 nM.

Pacritinib (SB1518) (SB1518) is an effective and specific inhibitor of JAK2 and FLT3 (IC50: 23 22 nM, in cell-free assays).

HPK1-IN-2 (Thieno[2,3-b]pyridin-6(7H)-one, 4-amino-5-[6-(4-methyl-1-piperazinyl)-1H-benzimidazol-2-yl]-HPK1-IN-2) is a potent and orally active inhibitor of hematopoietic progenitor kinase-1 (HPK1; IC50<0.05 μΜ). It also inhibits Lck (0.05 μΜFlt3 (IC50<0.05 μΜ) kinase activities with antitumor activity.

AKN-028 acetate, a novel tyrosine kinase (TK) inhibitor, is a potent, orally active FMS-like receptor tyrosine kinase 3 (FLT3) inhibitor with an IC50 value of 6 nM. It inhibits FLT3 autophosphorylation and induces a dose-dependent cytotoxic response (mean IC50 = 1 μM). AKN-028 acetate also induces apoptosis by activation of caspase 3 and can be used in acute myeloid leukemia (AML) research [1].

Pacritinib hydrochloride is a potent inhibitor of wild-type JAK2 (IC50: 23 nM) and the JAK2V617F mutant (IC50: 19 nM), and can be used in the study of acute myeloid leukaemia (AML) and myelofibrosis (MF).

1. Crotonoside (Isoguanosine) has much more active than adenosine in reducing the blood pressure in rabbits and cats, in decreasing the tone of isolated intestinal strips of the rabbit, guinea pig and hamster and in stimulating the isolated uterus of guinea pigs and hamsters. 2. Crotonoside inhibits the growth of S-18 and Ehrlich solid tumor in mice at the optimal doses of 96 mg kg day x 12 and 48 mg kg day x 12, with 1-T C values of 65% and 6%, respectively.

Antiproliferative Agent-34 (Compound A14), a multitarget kinase inhibitor, demonstrates IC50 values of 177 nM for EGFR L858R T790M and 1567 nM for EGFR WT. Additionally, it inhibits JAK2, ROS1, FLT3, FLT4, and PDGFRα with respective IC50s of 30.93 nM, 106.90 nM, 108.00 nM, 226.60 nM, and 42.53 nM. In normoxic conditions, it suppresses the proliferation of H1975 and HCC827 cells with IC50 values below 40 nM, while under hypoxic conditions, its potency increases 4-6 fold, yielding IC50 values less than 10 nM [1].

Pacritinib (SB1518) citrate effectively inhibits wild-type JAK2 (IC 50 =23 nM) and the JAK2 V617F mutant (IC 50 =19 nM). It also targets FLT3 (IC 50 =22 nM) and the FLT3 D835Y mutant (IC 50 =6 nM). This compound is utilized in the study of acute myeloid leukemia (AML) and myelofibrosis (MF) [1] [2] [3].

FLT3 ITD-IN-5 (Example 6) is an orally active inhibitor of both FLT3 and FLT3-ITD, exhibiting IC50 values of 0.088 nM and 0.348 nM, respectively. This compound is utilized in cancer research.

Pacritinib-d8 is a deuterated compound of Pacritinib. Pacritinib has a CAS number of 937272-79-2. Pacritinib (SB1518) is an effective and specific inhibitor of JAK2 and FLT3 (IC50: 23 22 nM, in cell-free assays).
