4-Hydroxy-2-quinolones 173*. 1-R-3-(2-diethylamino- ethyl)-1H-quinazoline- 2,4-dione hydrochlorides as potential local anesthetic agents
摘要:
Different variants of the preparation and procedures in the synthesis of a series of 1-R-3-(2-dialkylaminoethyl)-1H-quinazoline-2,4-dione hydrochlorides having a structural similarity to the 4-hydroxy-2-quinolinone anesthetic chinoxicaine are discussed. A comparative analysis of the biological properties of the synthesized compounds and the known local anesthetics chinoxicaine and lidocaine is reported.

Synthesis of quinazolindionyl amino acid derivatives as possible antitumour agents
摘要:
A series of 1-ethyl-2,4-dioxo-(1H,3H)-quinazolin-3-yl amino acid and hydrazone derivatives were synthesized and tested for their antitumor activity. The alcohol and acid derivatives of quinazolindione were conjugated with the amino acid derivatives at N-3 site via ester or amide bonds by carbodiimide and azide methods. The carbodiimide-mediated amide and esterification steps were performed in the presence of HOBt or DMAP respectively otherwise the side-products N-acyl urea derivatives are formed, instead of the desired derivatives. Nine compounds exhibited encouraging antitumor activity against human liver carcinoma cell line (HepG2).[GRAPHICS].
