Patent number: 9029394Abstract: 2-aryl-4-quinolones are converted into phosphates by reacting with tetrabenzyl pyrophosphate to form dibenzyl phosphates thereof, which are then subject to hydrogenation to replace dibenzyl groups with H, followed by reacting with Amberlite IR-120(Na+ form) to form disodium salts. The results of preliminary screening revealed that these phosphates showed significant anti-cancer activity. A novel intermediate, 2-selenophene 4-quinolone and N,N-dialkylaminoalkyl derivatives of 2-phenyl-4-quinolones are also synthesized. These novel intermediates exhibited significant anticancer activities.Type: GrantFiled: May 13, 2013Date of Patent: May 12, 2015Assignee: China Medical UniversityInventors: Sheng-Chu Kuo, Che-Ming Teng, Kuo-Hsiung Lee, Li-Jiau Huang, Li-Chen Chou, Chih-Shiang Chang, Chung-Ming Sun, Tian-Shung Wu, Shiow-Lin Pan, Tzong-Der Way, Jang-Chang Lee, Jing-Gung Chung, Jai-Sing Yang, Chien-Ting Chen, Ching-Che Huang, Shih-Ming Huang
