Blockage of more than one oncoprotein or pathway is now a standard approach in modern cancer therapy. Multiple inhibition is typically achieved with two or more drugs. Herein, we describe a pharmacophore merging strategy combining the JAK2/FLT3 inhibitor pacritnib with the pan-HDAC inhibitor, vorinostat, to create bispecific single molecules with both JAK and HDAC targeted inhibition. A preferred ether hydroxamate, 51, inhibits JAK2 and HDAC6 with low nanomolar potency, is 50-fold selective for JAK2 in a panel of 97 kinases. Broad cellular antiproliferative potency is supported by demonstration of JAK-STAT and HDAC pathway blockade in several hematological cell lines, inhibition of colony formation in HEL cells, and analysis of apoptosis. This study provides new tool compounds for further exploration of dual JAK-HDAC pathway inhibiton achieved with a single molecule.

Herein, we describe the synthesis and SAR of a series of small molecule macrocycles that selectively inhibit JAK2 kinase within the JAK family and FLT3 kinase. Following a multiparameter optimization of a key aryl ring of the previously described SB1518 (

Discovery of the activating mutation V617F in Janus Kinase 2 (JAK2 V617F), a tyrosine kinase critically involved in receptor signaling, recently ignited interest in JAK2 inhibitor therapy as a treatment for myelofibrosis (MF). Herein, we describe the design and synthesis of a series of small molecule 4-aryl-2-aminopyrimidine macrocycles and their biological evaluation against the JAK family of kinase enzymes and FLT3. The most promising leads were assessed for their in vitro ADME properties culminating in the discovery of 21c, a potent JAK2 (IC50 = 23 and 19 nM for JAK2 WT and JAK2V617F, respectively) and FLT3 (IC50 = 22 nM) inhibitor with selectivity against JAK1 and JAK3 (IC50 = 1280 and 520 nM, respectively). Further profiling of 21c in preclinical species and mouse xenograft and allograft models is described. Compound 21c (SB1518) was selected as a development candidate and progressed into clinical trials where it is currently in phase 2 for MF and lymphoma.
