Structural simplification of bioactive natural products with multicomponent synthesis. 4. 4H-Pyrano-[2,3-b]naphthoquinones with anticancer activity
摘要:
4H-Pyrano-[2,3-b]naphthoquinone is a structural motif commonly found in natural products manifesting anticancer activities. As part of a program aimed at structural simplification of bioactive natural products utilizing multicomponent synthetic processes, we developed a compound library based on this heterocyclic scaffold. We found that several library members displayed low micromolar antiproliferative activity and induced apoptosis in human cancer cells. Selected compounds showed promising activity against cancer cell lines resistant to proapoptotic stimuli, demonstrating their potential in treating cancers with dismal prognoses.

Abstract In this investigation, a new application of 1 H -imidazol-3-ium tricyanomethanide catalyst was explored. The catalyst presented a robust catalytic applicability for the preparation of naphthoquinone-based compounds under mild and green reaction conditions. A wide range of aromatic aldehydes were able to react with 2-hydroxynaphthalene-1,4-dione and 3-methyl-1-phenyl-1 H -pyrazol-5(4 H )-one

CeO<sub>2</sub>/CuO@N‐GQDs@NH<sub>2</sub>nanocomposite as a high‐performance catalyst for the synthesis of benzo[g]chromenes
A three‐component reaction of aromatic aldehydes, malononitrile or ethyl cyanoacetate and 2‐hydroxy‐1,4‐naphthaquinone has been achieved in the presence of an amino‐functionalized CeO2/CuO@ nitrogen graphene quantum dot nanocomposite as a highly effective heterogeneous catalyst to produce benzo[g]chromenes. The catalyst has been characterized by X‐ray diffraction, scanning electron microscopy, transmission
A series of 1,4-pyranonaphthoquinone derivatives were synthesized via the reaction of arylidenemalononitrile and 2-hydroxynaphthalene-1,4-dione in the mixed solvent of N,N-dimethylformamide and glacial acetic acid (HOAc) under microwave irradiation withoutcatalyst. This protocol has the notable advantages of short reaction time, high yield, and convenient operation. J. Heterocyclic Chem., (2009).
