- 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.

- Design, synthesis, biological evaluation and molecular docking studies of novel 3-aryl-4-anilino-2H-chromen-2-one derivatives targeting ERα as anti-breast cancer agents
-
The estrogen receptor (ER) has played an important role in breast cancer development and progression and is a central target for anticancer drug discovery. In order to develop novel selective ERα modulators (SERMs), we designed and synthesized 18 novel 3-aryl-4-anilino-2H-chromen-2-one derivatives based on previously reported lead compounds. The biological results indicated that most of the compounds presented potent ERα binding affinity and possessed better anti-proliferative activities against MCF-7 and Ishikawa cell lines than the positive control tamoxifen. The piperidyl substituted compounds such as 16d and 18d demonstrated strong ERα binding affinities and excellent anti-proliferative activities respectively. Compound 18d displayed the most potent ERα binding affinity with RBA value of 2.83%, while 16d exhibited the best anti-proliferative activity against MCF-7 cells with IC50 value of 4.52?±?2.47?μM. Further molecular docking studies were also carried out to investigate binding pattern of the newly synthesized compounds with ERα. All these results together with the structure–activity relationships (SARs) indicated that these 3-aryl-4-anilino-2H-chromen-2-one derivatives with basic side chain could serve as promising leads for further optimization as novel SERMs.

- Discovery of biphenyl-based VEGFR-2 inhibitors. Part 3: Design, synthesis and 3D-QSAR studies
-
VEGFR-2 plays an essential role in angiogenesis and is a central target for anticancer drug discovery. In order to develop novel VEGFR-2 inhibitors, we designed and synthesized 33 biphenyl amides based on our previously reported lead compound. The biological results indicated that four compounds (18b, 20e, 20h and 20j) are potent VEGFR-2 inhibitors which are comparable to positive control. Compound 18b displayed the most potent VEGFR-2 inhibition with IC50 value of 2.02 nM. Moreover, it exhibited promising antiproliferative activity against MCF-7 and SMMC-7721 cells with IC50 values of 1.47 μM and 5.98 μM, respectively. Molecular docking and 3D-QSAR studies were also carried out. The results indicated that these biphenyl amides could serve as promising leads for further optimization as novel VEGFR-2 inhibitors.

- Design, synthesis and biological evaluation of pyridin-3-yl pyrimidines as potent Bcr-Abl inhibitors
-
A series of pyridin-3-yl pyrimidines was synthesized and evaluated for their Bcr-Abl inhibitory and anticancer activity. The preliminary results indicated that some compounds were promising anticancer agents. Compounds A2, A8, and A9 exhibited potent Bcr-Abl inhibitory activity, suggesting that aniline containing halogen substituents might be important for biological activity. Molecular docking was carried out to investigate the binding mode of them with Bcr-Abl. Details of synthesis and SAR studies of these compounds are described. A series of phenylaminopyrimidines was designed and synthesized as potent Bcr-Abl inhibitors. The screening of these rationally designed compounds for antitumor activity had identified three candidate leads which could be further optimized to improve the anticancer activities.

- Design, synthesis and biological activities of Nilotinib derivates as antitumor agents
-
A novel class of Nilotinib derivatives, B1-B20, were synthesized in high yields using various substituted anilines. All the title compounds were evaluated for their inhibitory activities against Bcr-Abl and antiproliferative effects on human leukemia cell (K562). The pharmacological results indicated that some compounds exhibited promising anticancer activity. In particular, compound B14 containing tertiary amine side chain exhibited Bcr-Abl inhibitory activity similar to that of Nilotinib. It was suggested that the introduction of the tertiary amine moiety could improve Bcr-Abl inhibitory activity and antitumor effects.
