- Discovery of novel anti-angiogenesis agents. Part 8: Diaryl thiourea bearing 1H-indazole-3-amine as multi-target RTKs inhibitors
-
VEGFR-2, TIE-2, and EphB4 are essential for both angiogenesis and tumorigenesis. Herein, we designed and prepared three classes of multi-target inhibitors based on the extensive sequence homology along the kinase domain of angiogenic RTKs. Biological evaluation indicated that these multi-target inhibitors exhibited considerable potential as novel anti-angiogeneic and anticancer agents. Among them, a diaryl thiourea bearing 1H-indazole-3-amine (16a) displayed the most potent RTK inhibition and excellent selectivity. It also showed inhibition on viability of human umbilical vein endothelial cells and anti-proliferation against a broad spectrum of cancer cells. Therefore, 1H-indazole-3-amine could serve as a promising hinge binding group for multi-target inhibitors of VEGFR-2, Tie-2, and EphB4.

- Discovery of novel anti-angiogenesis agents. Part 7: Multitarget inhibitors of VEGFR-2, TIE-2 and EphB4
-
Herein, we embarked on a structural optimization campaign aiming at the discovery of second generation anti-angiogenesis agents with our previously reported BPS-7 as lead compound. A library of 27 compounds has been afforded based on the highly conserved ATP-binding pocket of VEGFR-2, Tie-2, and EphB4. Several title compounds exhibited simultaneous inhibitory effects against three angiogenic RTKs. These compounds with a ‘triplet’ inhibition profile have been identified as novel anti-angiogenic and anticancer agents. The representative VDAU11 displayed prominent anti-angiogenic and anticancer potency and could be considered as a candidate for further optimization. These results indicate that N-(pyridin-2-yl)acrylamide could serve as a novel hinge-binding group of triple inhibitors.

- Diaryl urea compounds with anti-tumor activity as well as preparation method and application of diaryl urea compounds
-
The invention provides diaryl urea compounds with anti-tumor activity as well as a preparation method and an application of the diaryl urea compounds. A structural formula of the compounds is shown in the specification, wherein R1 represents hydrogen, and R2 represents isopropyl or halogen groups. The compounds have good inhibition activity for VEGFR-2 (vascular endothelial growth factor-2) kinase, and can block VEGFR-2 kinase induced signaling pathways and inhibit tumor cell proliferation and migration by inhibiting activity of VEGFR-2 kinase, so that the compounds can be applied to preparation of anti-tumor drugs. Besides, the preparation method of the compounds has the advantages that raw materials are easily available, reaction conditions are mild, a reaction process is simple to operate and used reagents are cheap.

- Diarylurea compound with antitumor activity, and preparation method and application thereof
-
The invention provides a diarylurea compound with antitumor activity, and a preparation method and application thereof. The compound has a structural formula as described in the specification. In the structural formula, R1 and R2 are selected from the group consisting of hydrogen, alkane groups or halogen groups. The compound provided by the invention has good inhibitory activity to VEGFR-2 kinase, so a signal channel induced by the VEGFR-2 kinase can be blocked through inhibition of the activity of the VEGFR-2 kinase, and proliferation and migration of tumor cells are inhibited; thus, the compound can be applied in preparation of antitumor drugs. Meanwhile, the preparation method for the compound has the following advantages: raw materials are easily available; reaction conditions are mild; the process of reaction is simple to operate; and used reagents are cheap.

- Discovery of N-(4-(3-amino-1H-indazol-4-yl)phenyl)-N′-(2-fluoro-5- methylphenyl)urea (ABT-869), a 3-aminoindazole-based orally active multitargeted receptor tyrosine kinase inhibitor
-
In our continued efforts to search for potent and novel receptor tyrosine kinase (RTK) inhibitors as potential anticancer agents, we discovered, through a structure-based design, that 3-aminoindazole could serve as an efficient hinge-binding template for kinase inhibitors. By incorporating an N,N′-diaryl urea moiety at the C4-position of 3-aminodazole, a series of RTK inhibitors were generated, which potently inhibited the tyrosine kinase activity of the vascular endothelial growth factor receptor and the platelet-derived growth factor receptor families. A number of compounds with potent oral activity were identified by utilizing an estradiol-induced mouse uterine edema model and an HT1080 human fibrosarcoma xenograft tumor model. In particular, compound 17p (ABT-869) was found to possess favorable pharmacokinetic profiles across different species and display significant tumor growth inhibition in multiple preclinical animal models.
