Design, synthesis and biological evaluation of novel 7-amino-[1,2,4]triazolo[4,3-f]pteridinone, and 7-aminotetrazolo[1,5-f]pteridinone derivative as potent antitumor agents

To develop novel therapeutic agents with anticancer activities, two series of novel 7-amino-[1,2,4]triazolo[4,3-f]pteridinone, and 7-aminotetrazolo[1,5-f]pteridinone derivatives were designed and synthesized. All compounds were tested for anti-proliferative activities against five cancer cell lines. The structure-activity relationships (SARs) studies were conducted through the variation in two regions, the moiety of A ring and the terminal aniline B on pteridinone core. 1-Methyl-1,2,4-triazole derivative L7 with 2,6-dimethylpiperazine showed the most potent antiproliferative activity against A549, PC-3, HCT116, MCF-7 and MDA-MB-231 cell lines with IC50 values of 0.16 μM, 0.30 μM, 0.51 μM, 0.30 μM, and 0.70 μM, respectively. Combined with the results of the molecular docking and enzymatic studies, the PLK1 was very likely to be one of the drug targets of compound L7. Furthermore, to clarify the anticancer mechanism of compound L7, further explorations in the bioactivity were conducted. The results showed that compound L7 obviously inhibited proliferation of A549 cell lines, induced a great decrease in mitochondrial membrane potential leading to apoptosis of cancer cells, suppressed the migration of tumor cells, and arrested G1 phase of A549 cells.

Design, synthesis and biological evaluation of novel 2,4-diaminopyrimidine derivatives as potent antitumor agents

For developing novel therapeutic agents with anticancer activities, two series of novel 2,4-diaminopyrimidine derivatives possessing triazolopiperazine or 1,4,8-triazaspiro[4.5]decan-3-one scaffolds were designed and synthesized. Preliminary investigations showed that some compounds exhibited moderate to excellent potency against four tested cancer cell lines as compared with palbociclib and momelotinib. In particular, the most promising compounds 9k and 13f showed the most potent antitumor activities with IC50 values of 2.14/1.98 μM, 3.59/2.78 μM, 5.52/4.27 μM, and 3.69/4.01 μM against A549, HCT-116, PC-3 and MCF-7 cell lines, respectively. Structure-activity relationship (SAR) studies were conducted based on the variation of the moiety of the aromatic ring and the terminal aniline on the pyrimidine core. Furthermore, the mechanism of their anticancer activity was clarified by further exploring the bioactivity. The results showed that compound 9k obviously inhibited the proliferation of A549 cell lines, induced a great decrease in the mitochondrial membrane potential leading to apoptosis of cancer cells, suppressed the migration of tumor cells and prolonged the A549 cell cycle distribution, representing blockage at the G2-M phase and accumulation at the S phase.

Discovery of 4-piperazinyl-2-aminopyrimidine derivatives as dual inhibitors of JAK2 and FLT3

Hybridization strategy is an effective strategy to obtain multi-target inhibitors in drug design. In this study, we assembled the pharmacophores of momelotinib and tandutinib to get a series of 4-piperazinyl-2-aminopyrimidine derivatives. All compounds were tested for the inhibition of JAK2 and FLT3 enzymes, of which, compounds with potent enzyme activities were assayed for antiproliferative activities against three cancer cell lines (HEL, MV4-11, and HL60). The structure-activity relationship studies were conducted through variations in two regions, the “A” phenyl ring and “B” phenyl ring. Compound 14j showed the most balanced in vitro inhibitory activity against JAK2 and FLT3 (JAK2 IC50 = 27 nM, FLT3 IC50 = 30 nM), and it also showed potent inhibition against the above tested cell lines. In the cellular context, 14j strongly induced apoptosis by arresting cell cycle in the G1/S phase, and was selected as a promising JAK2/FLT3 dual inhibitor.

Regiospecific N-Arylation of Aliphatic Amines under Mild and Metal-Free Reaction Conditions

A transition metal-free N-arylation of primary and secondary amines with diaryliodonium salts is presented. Both acyclic and cyclic amines are well tolerated, providing a large set of N-alkyl anilines. The methodology is unprecedented among metal-free methods in terms of amine scope, the ability to transfer both electron-withdrawing and electron-donating aryl groups, and efficient use of resources, as excess substrate or reagents are not required.
