Synthesis of 6-arylisocytosines and their potential for hydrogen bonding interactions
摘要:
The synthesis of a number of 6-arylisocytosines, including linked bis-isocytosines, from the reaction of guanidine with beta-ketoesters is described. The compounds were investigated for their ability to form hydrogen-bonded structural networks, and for their potential interactions with the telomeric quadruplex forming sequence AGGG(TTAGGG)(3).

based inhibitors of xanthine oxidase is described. After a high-throughput screening campaign, an NMR based counterscreen was used to distinguish actives, which interact with XO in a reversible manner, from assay artefacts. This approach identified pyrimidone 1 as a reversible and competitiveinhibitor with good lead-like properties. A hit to lead campaign gave compound 41, a nanomolar inhibitor of hXO
