The directed synthesis of 2-(piperazin-1-yl)quinazolin-4-one, 2-(homopiperazin-1-yl)quinazolin-4-one and 2-(2,5-diazabicyclo[2.2.1]heptan-2-yl)quinazolin-4-one derivatives was carried out. It was shown that the studied 2,6-substituted quinazolin-4-one derivatives inhibit the binding of fibrinogen to αIIbβ3 with IC50 values from 33 μM to 0.1 μM. The antiaggregatory properties of the synthesized 3H-quinazolin-4-one derivatives were also studied and it was found that the IC50 values are in the range from 62 μM to 0.04 μM. According to the previously developed method, 7- and 9-(dialkylaminoalkyl)amino triptanthrines were prepared - potential DNA intercalators and antiviral agents, and at the same time - precursors for the synthesis of potential anti-inflammatory drugs. The methods for the synthesis of 8-hydroxy and 8-aminotriptanthrine - convenient precursors for the synthesis of water-soluble triptanthrine derivatives - potential therapeutic agents - were optimized. Starting from N-(4-hydroxyphenyl)acetamide, 7(8)-(dialkylaminoethoxy)indenoquinoxalinones were synthesized in the form of a regioisomeric mixture. Separation of the mixture and establishment of the absolute configuration of the products are ongoing. The affinity of the synthesized compounds to DNA was studied by fluorimetric titration. All the studied compounds belong to intercalators of moderate strength. Product Description popup.authors Krysko Andrii А. Karpenko Oleksandr S. Kornilov Oleksandr Yu.
