Quinazoline or quinoline derivatives of formula: (Formula I and II); wherein Z is CH or N; Y is O or S; X is OR5 or NR5R6; R1, R2, R3, R4, R5 and R6 are as disclosed. Also described is a method for the inhibiting the prolyl peptidase, inducing apoptosis and treating cancer by administering a therapeutically effective amount of compounds of the formula (I) or (II).
Triplex stability of oligodeoxynucleotides containing substituted quinazoline-2,4-(1H,3H)-dione
can be observed between double-stranded nucleicacids and a third strand through the formation of Hoogsteen hydrogen bond. We report here the use of quinazoline-2,4-dione derivatives as substitutes for thymine in TA∗T triplets. The synthesis and the characterization of monochloro derivatives of quinazoline-2,4-dione as well as 5-fluoro and 6-nitro substituted quinazoline rings are described. The ability
