摘要

Some S'-substituted 4-alkyl (aryl) thioquinazoline derivatives were synthesized through thioetherification reaction of 4-chloroquinazolines 2 and thiol compounds 1 refluxed in acetone in the presence of K2CO3. Their structures were verified by elemental analysis, IR, 1H NMR, and 13C NMR. The compounds were evaluated for their anti-proliferative activities against some cancer cells in vitro by MTT method. Among them, 3c, 3a, 3d, 3f, and 3l were highly effective against PC3 cells and 3a-3m showed weak activities against Bcap37 and BGC823 cells. The IC50 value of 3c, 3a, 3d, 3f, and3l against PC3 cell was 1. 8, 5. 6, 8. 1, 8. 7, and 8. 9 μM, respectively.

摘要

Chiral α-aminophosphonates were synthesized using (R) or (S)-1-phenylethylamine in the presence of BF3•Et2O under microwave irradiation in moderate to good yields. The new compounds were identified by 1H NMR, 19F NMR, IR and elemental analysis. Their antifungal activities were evaluated and some compounds were found to exhibit excellent antifungal activities. To the best of our knowledge, this is the first report on antifungal activity of chiral α-aminophosphonates containing fluorine moiety.

摘要

In the title compound, C22H26F3N2O3PS, there are two independent molecules in the asymmetric unit. The two molecules differ in the orientation of the benzene ring with respect to the benzothiazole group [dihedral angles 58. 6 (2) and 71. 6 (2)0]. In the crystal structure, symmetry-related molecules are linked by N—H· · ·O hydrogen bonds.
