Abstract: In the present study, a series of novel dual-target histone deacetylase (HDAC) and mammalian target of rapamycin (mTOR) inhibitors were designed and synthesized using pyrimidine-pyrazolyl pharmacophore to append HDAC recognition cap and hydroxamic acid as a zinc-binding motif. Among them, 12l was the optimal lead compound with potent inhibition activities against mTOR and HDAC1 with half-maximal inhibitory concentration of 1.2 and 0.19 nM, respectively. Western blot confirmed that 12l could upregulate acetylation of H3 and α-tubulin and downregulate mTOR-related downstream mediators. 12l could also stimulate cell cycle arrest in G0/G1 phase and induce tumor cell apoptosis. 12l showed comparable antitumor activity with the combination medication in MM1S xenograft model with a tumor growth inhibitory rate of 72.5%, without causing significant loss of body weight and toxicity. All of the results indicated that 12l could be a promising dual target inhibitor for treating hematologic malignancies.
