A new heterocyclic compound 7-methoxy-6-(3-morpholinopropoxy)quinazolin-4(3H)-one (1), designed using methyl 5-hydroxy-4-methoxy-2-nitrobenzoate (2) as the starting material, was successfully obtained via multiple synthesis route and finally characterized by fourier transform infrared (FT-IR) spectroscopy, 1H nuclear magnetic resonance (NMR), and single crystal X-ray crystallography. We investigated its effect on cell viability and proliferation with Cell Counting Kit-8 (CCK8) assay. The results revealed that compound 1 could block the proliferation of Saos-2 bone cancer cells. In addition, Annexin V-FITC/PI assay and Western blot analysis were performed to detect whether compound 1 could induce cell apoptosis. The results indicated that compound 1 could increase the number of apoptotic cells remarkably. Moreover, we examined the impact of compound 1 on ROS generation. Results revealed that compound 1 up-regulated the reactive oxygen species (ROS) genes expression and promoted the accumulation of ROS in Saos-2 cells. Finally, molecular docking has been utilized to study the binding mode of compound 1 with tubulin.

Inhibitors of tyrosine kinase enzymatic activity represent a promising new class of antineoplastic agents. Although clinical studies performed over the last decade give more insight on the potential therapeutic applications of such drugs, identification of the individual patients who might benefit from them remains a major challenge. We have developed a synthetic strategy for the production of a wide variety of radiolabeled 6,7-disubstituted 4-anilinoquinazolines suitable for noninvasive imaging of tyrosine kinase receptors to predict therapy effectiveness. Three new F-18 labeled radiopharmaceuticals based on the therapeutic agents Tarceva, Iressa, and ZD6474 were synthesized. Decay-corrected yields varied between 25 and 40% for a total synthesis time of 120 min, thus providing F-18 labeled tyrosine kinase inhibitors in quantities and times practical for use as PET radiopharmaceuticals.
