Background:
A green and efficient synthetic methodology for a wide family of Nacylhydrazones
(yields: 42-76%) using microwave irradiation is described, as well as their full characterization.
Their potential antineoplastic activity was evaluated in vitro via EMSA by testing protein-
DNA interactions. Among the 11 compounds tested, N-acylhydrazone derivative 5 bearing a hydroxyl
group, showed the highest affinity to bind and inhibit the hnRNP K KH3 domain. Docking simulations
of compound 5 showed three possible modes of interaction between the KH3 domain of hnRNP K protein
and compound predict.
:
The N-acylhydrazones are knows as powerful chemical entities for Medicinal Chemistry, since it has
been identified in a huge number of hit and lead compounds that act on various types of molecular targets,
including in tumorigenesis processes.
Objective:
We evaluated their potential ability to inhibit the KH3 domain of the hnRNP K protein binding
to single stranded DNA (ssDNA). Furthermore, a docking simulation was performed for the newly
synthetized compounds to evaluate their interactions between proteins and N-acylhydrazine derivative.
Methods:
The N-acylhydrazone derivatives were synthetized through three reaction steps, from a simple
and commercial substrate, using microwave irradiation as a green energy source. The N-acylhydrazone
derivatives ability to bind with the hnRNP K protein was evaluated via EMSA by testing protein-DNA
interactions. The docking simulations were performed in a Gold 5.2.2 software using 100 conformers,
10.000 operations, 95 mutations and 95 crossovers.
Results:
Eleven new N-acylhydrazone derivatives were synthetized using microwave showing yields
between 42% and 76%. Among the eleven compounds tested, compound 5 was shown to be most
capable to prevent the natural binding of hnRNP K protein to the oligonucleotide. Regarding the docking
simulation, compound 5 can bind to the main binding residues of KH3 domain and compete with the
natural ligand ssDNA of this protein.
Conclusion:
A green and efficient synthetic methodology for a wide family of N-acylhydrazones
(yields: 42-76%) using microwave irradiation is described, as well as their full characterization. Their
potential antineoplastic activity was evaluated in vitro via EMSA by testing protein-DNA interactions.
Among the 11 compounds tested, N-acylhydrazone derivative 5 bearing a hydroxyl group, showed the
