SARs of a novel series of s-triazine compounds targeting vimentin to induce methuotic phenotype

Herein, we describe the design, synthesis and structure?activity relationships of a series of novel s-triazine compounds can induce methuotic phenotype in various types of cancer cells. (E)-1-(4-Chlorophenyl)-3-(4-((4-morpholino-6-styryl-1,3,5-triazine-2-yl)amino)phenyl)urea, compound V6, exhibited a striking methuotic phenotype with a minimal effective concentration of less than 10 nM in U87 glioblastoma cells. Based on structure?activity relationship studies, we designed and synthesized an active probe P1 that retained the full potential of V6 in inducing the methuotic phenotype in U87 glioblastoma cells. Using this probe following affinity-based proteomic profiling strategy, we identified vimentin as the specific target protein of compound V6. Molecular docking revealed that V6 can form hydrogen bonds with vimentin at 273R and 276Y in its rod domain.

Discovery of novel 2,4-disubstituted pyrimidines as Aurora kinase inhibitors

In order to explore novel Aurora kinase inhibitors, a series of novel 2,4-disubstituted pyrimidines were designed, synthesized and evaluated their in vitro anti-proliferative activities against a panel of cancerous cell lines (A549, HCT-116 and MCF-7). Among them, compound 12a showed the moderate to high anti-proliferative activities against A549 (IC50 = 12.05 ± 0.45 μM), HCT-116 (IC50 = 1.31 ± 0.41 μM) and MCF-7 (IC50 = 20.53 ± 6.13 μM) cells, as well as the Aurora A and Aurora B inhibitory activities with the IC50 values of 309 nM and 293 nM, respectively. Furthermore, compound 12a induced apoptosis by upregulated the pro-apoptotic proteins Bax and decreased the anti-apoptotic protein Bcl-xl in HCT-116 cells. Moreover, the molecular docking study showed that compound 12a had good binding modes with Aurora A and Aurora B and the bioinformatics prediction discovered that compound 12a exhibited good drug likeness using SwissADME. Taken together, these results indicated that 12a may be a potential anticancer compound that was worthy of further development as Aurora kinase inhibitor.

Discovery of N-phenyl-(2,4-dihydroxypyrimidine-5-sulfonamido) phenylurea-based thymidylate synthase (TS) inhibitor as a novel multi-effects antitumor drugs with minimal toxicity

Thymidylate synthase (TS) is a hot target for tumor chemotherapy, and its inhibitors are an essential direction for anti-tumor drug research. To our knowledge, currently, there are no reported thymidylate synthase inhibitors that could inhibit cancer cell migration. Therefore, for optimal therapeutic purposes, combines our previous reports and findings, we hope to obtain a multi-effects inhibitor. This study according to the principle of flattening we designed and synthesized 18 of N-phenyl-(2,4-dihydroxypyrimidine-5-sulfonamido)phenyl urea derivatives as multi-effects inhibitors. The biological evaluation results showed that target compounds could significantly inhibit the hTS enzyme, BRaf kinase and EGFR kinase activity in vitro, and most of the compounds had excellent anti-cell viability for six cancer cell lines. Notably, the candidate compound L14e (IC50 = 0.67 μM) had the superior anti-cell viability and safety to A549 and H460 cells compared with pemetrexed. Further studies had shown that L14e could cause G1/S phase arrest then induce intrinsic apoptosis. Transwell, western blot, and tube formation results proved that L14e could inhibit the activation of the EGFR signaling pathway, then ultimately achieve the purpose of inhibiting cancer cell migration and angiogenesis in cancer tissues. Furthermore, in vivo pharmacology evaluations of L14e showed significant antitumor activity in A549 cells xenografts with minimal toxicity. All of these results demonstrated that the L14e has the potential for drug discovery as a multi-effects inhibitor and provides a new reference for clinical treatment of non-small cell lung cancer.

Design, synthesis and molecular modeling study of certain VEGFR-2 inhibitors based on thienopyrimidne scaffold as cancer targeting agents

Different series of novel thieno [2,3-d]pyrimidine derivative (9a-d,10a-f,l,m and 15a-m) were designed, synthesized and evaluated for their ability to in vitro inhibit VEGFR-2 enzyme. Also, the cytotoxicity of the final compounds was tested against a panel of 60 different human cancer cell lines by NCI. The VEGFR-2 enzyme inhibitory results revealed that compounds 10d, 15d and 15 g are among the most active inhibitors with IC50 values of 2.5, 5.48 and 2.27 μM respectively, while compound 10a remarkably showed the highest cell growth inhibition with mean growth inhibition (GI) percent of 31.57%. It exhibited broad spectrum anti-proliferative activity against several NCI cell lines specifically on human breast cancer (T7-47D) and renal cancer (A498) cell lines of 85.5% and 77.65% inhibition respectively. To investigate the mechanistic aspects underlying the activity, further biological studies like flow cytometry cell cycle together with caspase-3 colorimetric assays were carried on compound 10a. Flow cytometric analysis on both MCV-7 and PC-3 cancer cells revealed that it induced cell-cycle arrest in the G0-G1phase and reinforced apoptosis via activation of caspase-3. Furthermore, molecular modeling studies have been carried out to gain further understanding of the binding mode in the active site of VEGFR-2 enzyme and predict pharmacokinetic properties of all the synthesized inhibitors.

Phenyl and Diaryl Ureas with Thiazolo[5,4-d]pyrimidine Scaffold as Angiogenesis Inhibitors: Design, Synthesis and Biological Evaluation

Angiogenesis is crucial for tumor growth and inhibition of angiogenesis has been regarded as a promising approach for cancer therapy. Vascular endothelial growth factor receptor-2 (VEGFR-2) is an important factor in angiogenesis. In this work, a novel series of thiazolo[5,4-d]pyrimidine derivatives inhibiting angiogenesis were rationally designed and synthesized. Their inhibitory activities against human umbilical vein endothelial cells (HUVEC) were investigated in vitro. 1-(4-Fluorophenyl)-3-{4-[(5-methyl-2-phenyl[1,3]thiazolo[5,4-d]pyrimidin-7-yl)amino]phenyl}urea (19b) and 1-(3-Fluorophenyl)-3-{4-[(5-methyl-2-phenyl[1,3]thiazolo[5,4-d]pyrimidin-7-yl)amino]phenyl}urea (19g) exhibited the most potent inhibitory effect on HUVEC proliferation (IC50=12.8 and 5.3 μm, respectively). Compound 19g could inhibit the migration of human umbilical vein endothelial cells. These results support the further investigation of these compounds as potent anticancer agents.

Design and discovery of 4-anilinoquinazoline-urea derivatives as dual TK inhibitors of EGFR and VEGFR-2

EGFR and VEGFR-2 are involved in pathological disorders and the progression of different kinds of tumors, the combined blockade of EGFR and VEGFR signaling pathways appears to be an attractive approach to cancer therapy. In this work, a series of 4-anilinoquinazoline derivatives containing substituted diaryl urea or glycine methyl ester moiety were designed and identified as EGFR and VEGFR-2 dual inhibitors. Compounds 19i, 19j and 19l exhibited the most potent inhibitory activities against EGFR (IC50?=?1?nM, 78?nM and 51?nM, respectively) and VEGFR-2 (IC50?=?79?nM, 14?nM and 14?nM, respectively), they showed good antiproliferative activities as well. Molecular docking established the interaction of 19i with the DFG-out conformation of VEGFR-2, suggesting that they might be type II kinase inhibitors.

Increasing the binding affinity of VEGFR-2 inhibitors by extending their hydrophobic interaction with the active site: Design, synthesis and biological evaluation of 1-substituted-4-(4-methoxybenzyl)phthalazine derivatives

A series of anilinophthalazine derivatives 4a-j was initially synthesized and tested for its VEGFR-2 inhibitory activity where it showed promising activity (IC50 = 0.636-5.76 μM). Molecular docking studies guidance was used to improve the binding affinity for series 4a-j towards VEGFR-2 active site. This improvement was achieved by increasing the hydrophobic interaction with the hydrophobic back pocket of the VEGFR-2 active site lined with the hydrophobic side chains of Ile888, Leu889, Ile892, Val898, Val899, Leu1019 and Ile1044. Increasing the hydrophobic interaction was accomplished by extending the anilinophthalazine scaffold with a substituted phenyl moiety through an uriedo linker which should give this extension the flexibility required to accommodate itself deeply into the hydrophobic back pocket. As planned, the designed uriedo-anilinophthalazines 7a-i showed superior binding affinity than their anilinophthalazine parents (IC50 = 0.083-0.473 μM). In particular, compounds 7g-i showed IC50 of 0.086, 0.083 and 0.086 μM, respectively, which are better than that of the reference drug sorafenib (IC50 = 0.09 μM).

Diarylureas and Diarylamides with Oxazolo[5,4-d]pyrimidine Scaffold as Angiogenesis Inhibitors

A series of oxazolopyrimidine-based ureas and amides were designed, synthesized, and biologically evaluated for their antiproliferative and antiangiogenic activities. These compounds were identified to exhibit inhibitory activities against human umbilical vein endothelial cells (HUVEC) in vitro. Among these compounds, compound 22 effectively inhibited the migration and capillary-like tube formation of human umbilical vein endothelial cells. It also exhibited a concentration-dependent inhibition on capillary sprouting from the rat aorta rings. Preliminary mechanistic studies revealed that compound 22 suppressed protein kinases activation, by decreasing PI3K and ERK 1/2 phosphorylation. These results support the further investigation of this class of compounds as potential anticancer agents.
