title: MS and NMR investigation of bioactive quinazolones.
abstract: To prepare effective PARP [poly(ADP)-ribose)polymerase-1] inhibitors, starting from 2-mercapto-4(3H)-quinazolone (1), several S-alkyl derivatives--2-alkylsulfanyl-3H-quinazolin-4-ones (2-5, 7-9)--as well as an S-benzyl derivative (10) were prepared using a simple alkylation method. Some of them are known compounds. Their structure was studied thoroughly by MS and NMR methods.
