In accordance with the significant impetus of the discovery of potent vascular endothelial growth factor receptor 2 (VEGFR-2) inhibitors, herein, we report the design, synthesis, and anticancer evaluation of 12 new N-substituted-4-phenylphthalazin-1-amine derivatives against HepG2, HCT-116, and MCF-7 cells as VEGFR-2 inhibitors. The results of the cytotoxicity investigation indicated that HCT-116 and MCF-7 were the most sensitive cell lines to the influence of the newly synthesized derivatives. In particular, compound 7a was found to be the most potent derivative among all the tested compounds against the three cancer cell lines, HepG2, HCT116, and MCF-7, with IC50 = 13.67 +/- 1.2, 5.48 +/- 0.4, and 7.34 +/- 0.6 mu M, respectively, which is nearly equipotent to that of sorafenib (IC50 = 9.18 +/- 0.6, 5.47 +/- 0.3, and 7.26 +/- 0.3 mu M, respectively). All synthesized derivatives, 4a,b-8a-c, were evaluated for their inhibitory activities against VEGFR-2. The tested compounds displayed high to low inhibitory activity, with IC50 values ranging from 0.14 +/- 0.02 to 9.54 +/- 0.85 mu M. Among them, compound 7a was found to be the most potent derivative that inhibited VEGFR-2 at an IC50 value of 0.14 +/- 0.02 mu M, which is nearly 72% of that of the sorafenib IC50 value (0.10 +/- 0.02 mu M). Compounds 7b, 8c, 8b, and 8a exhibited very good activity with IC50 values of 0.18 +/- 0.02, 0.21 +/- 0.03, 0.24 +/- 0.02, and 0.35 +/- 0.04 mu M, respectively. Molecular modeling studies were carried out for all compounds against the VEGFR-2 active site. The data obtained from biological testing highly correlated with that obtained from molecular modeling studies. However, these modifications led to new phthalazine derivatives with higher VEGFR-2 inhibitory activities than vatalanib and which are nearly equipotent to sorafenib.

In this work, a series of 2H-indazolo[2,1-b]phthalazine-triones and Biginelli-like products were efficiently synthesized for the first time using O-Sulfonic acid poly(4-vinylpyrrolidonium) chloride ([PVP-SO3H]Cl) as an eco-friendly polymer-supported catalyst. At first, the catalyst preparation process was optimized based on the chlorosulfonic acid amount and the sulfonation time to obtain a catalyst with the maximum acidity content. The maximum acidity content for [PVP-SO3H]Cl was obtained to be 3.31 mmol g(-1). Then, the optimized [PVP-SO3H]Cl was used as a catalyst for the synthesis of a series of 2H-indazolo[2,1-b]phthalazine-triones and Biginelli-like products. It was observed that only 10 mg of the catalyst was enough to catalyze these reactions under mild conditions, and the corresponding products were obtained in high to excellent yields. Moreover, the catalyst could be repeatedly used for at least five times without a noticeable decrease in its catalytic activity.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 54381-16-7, you can contact me at any time and look forward to more communication. Recommanded Product: 2,2′-((4-Aminophenyl)azanediyl)diethanol sulfate.
