Synthesis of 5,6-dimethoxyquinazolin-2(1H)-one derivatives was the subject of investigations leading to the preparation of title compounds 11, 13, 14 and 26. Target quinazolines 1 were synthesized in three ways; the route starting from o-vanillin via the intermediacy of 6-amino-2,3-dimethoxyacetophenone (19) was used for most of the preparative work. The unexpected formation of an acid-labile dimer
A process for preparing 2-acyl-3,4-dialkoxyanilines is described. The 2-acyl-3,4-dialkoxyanilines are useful intermediates in the preparation of 5,6-dialkoxy-4-alkyl-2(1H)-quinazolinones. The substituted quinazolinones are active as cardiotonic agents.

The present invention pertains to the modification of the eukaryotic ubiquitin system by using the bacterial virulence factor SdeA and variants and mutants thereof. The invention is based on the phosphodiesterase activity of SdeA, which catalyzes a phospho-ribosylation (or simply "ribosylation") event of ubiquitin and ubiquitin-like proteins. The invention provides SdeA proteins and mutants without said phosphodiesterase activity, as well as medical applications of these recombinant proteins, their encoding nucleic acids, ribosylated ubiquitin proteins, and compounds which may act as selective or non-selective phosphodiesterase inhibitors.
