Main results
The project has successfully accomplished all its objectives and research contents, achieving the following main results:
­ On Chemical Synthesis: Successfully established efficient synthetic procedures using green/inexpensive catalysts (Fe, Cu) or multicomponent one-pot reactions to create 129 novel heterocyclic compounds (exceeding the registered target) belonging to 5 structural frameworks: Benzo[f]indole, Chromeno[2,3-d]pyrimidine, Indolopyrano[2,3-d]pyrimidine, Carboline, and Imidazopyridine. All compounds were fully characterized by modern spectroscopic methods (NMR, MS).
­ On Biological Evaluation: Screened and identified several compounds with potent activity, notably:
Cytotoxic activity: Chromeno[2,3-d]pyrimidine derivatives (10c, 10l) and BimPy derivatives (32b, 32c) strongly inhibited lung (A549), breast (MCF-7), and liver (HepG2) cancer cell lines with IC₅₀ values ranging from 1.7 – 4.3 µM, comparable to or better than the reference drug Ellipticine.
Enzyme inhibitory activity: Indolopyrano[2,3-d]pyrimidine derivatives (10’d, 10’e) exhibited α-glucosidase inhibitory activity superior to the drug Acarbose, opening up potential applications in diabetes treatment.
­ On Publications and Training:
Published 04 papers in prestigious international SCIE journals (RSC Advances, ChemistrySelect, Bioorg. Med. Chem. Lett.), exceeding the target (03 papers).
Successfully supported the training of 02 Masters, exceeding the target (01 Master).
Novelty and actuality and scientific meaningfulness of the results
­- Methodology: The project contributed advanced synthetic solutions (domino reactions, oxidative C-H/C-H coupling), allowing for the rapid construction of complex heterocyclic molecular frameworks from simple starting materials, minimizing costs and environmental impact.
­- Practical Value: The discovery of "hit compounds" with potent and selective inhibitory activity (especially superior α-glucosidase inhibition compared to commercial drugs) provides valuable data for the future development of new drugs for cancer and diabetes treatment.
­- Provided new and valuable scientific data on the structure-activity relationship (SAR) of the studied heterocyclic classes, serving as a basis for designing and optimizing drug molecules in the future.
