The discovery of novel anti-AML therapeutic agents is urgently needed, but the complex heterogeneity of the disease has so far hampered the development of a curative treatment. FLT3 inhibitors have shown therapeutic potential in clinical trials; but a monotherapy regimen has been associated with resistance mediated by the activation of parallel signalling circuitry, including MAPK and mTOR. Therefore, inhibiting a nexus of the two signalling pathways along with inhibition of FLT3 might be advantageous. Herein, we propose that a dual inhibition of FLT3 and Mnk would provide a better clinical option for AML patients compared to targeting FLT3 alone. Thus, a series of N-phenyl-4-(thiazol-5-yl)pyrimidin-2-amines and 4-(indol-3-yl)-N-phenylpyrimidin-2-amines were prepared. Potent Mnk2 inhibitors, FLT3 inhibitors, and dual inhibitors of Mnk2 and FLT3 were identified and their anti-proliferative activities assessed against MV4-11 AML cell lines. Dual inhibition of FLT3 and Mnk2 caused the increased apoptotic cell death of MV4-11 cells compared to inhibition of FLT3 or Mnk2 alone.
One-pot desulfonylative alkylation of N-sulfonyl azacycles using alkoxides generated by phase-transfer catalysis

Sulfonamide heterocycles, specifically 3-acylindoles, undergo a deprotection/alkylation sequence in the presence of an appropriate alcohol when cesium carbonate or potassium carbonate and a phase-transfer catalyst are utilized. The outcome of the one-pot protocol was found to be significantly dependent on both the alcohol and sulfonamide heterocycle employed. Strictly anhydrous conditions are not necessary for this protocol. Georg Thieme Verlag Stuttgart · New York.
Novel heterocycle-substituted pyrimidines as inhibitors of NF-κB transcription regulation related to TNF-α cytokine release

Novel heterocyclic ring-substituted pyrimidines have been designed as inhibitors of glycogen synthase kinase-3β (GSK-3β) from the modification of known inhibitors. Several potent inhibitors exhibiting nanomolar activities were discovered against GSK-3β kinase as well as in an NF-κB reporter gene assay. Based on the results from in vitro TNF-α release inhibition and in vivo endotoxima, these inhibitors are expected to be useful candidates for treatment of inflammation-related diseases.
