Microwave-assisted synthesis, molecular docking and anti-HIV activities of some drug-like quinolone derivatives

In targeted therapy of breast cancer, human epidermal growth factor receptor 2 HER2 (PDB ID: 3PP0) is being considered as a promising route to design novel anti-breast cancer drugs. In this work, we report two of novel N-substituted pyrrolidine at C-8 position of quinolone derivatives 18 and 19, their synthesis under microwave technique, spectral methods, molecular docking study and anti-HIV activities. Docking study exhibited hydrogen bonding, polar, and Van der Waals interactions with the active site residues of HER2 target. The binding energy and hydrogen bonding interactions show that synthesized compounds are being considered to have a potential activity against breast cancer. In addition, quinolone derivatives were evaluated in vitro for antiviral activity against the replication of HIV-1 and HIV-2 in MT-4 cells. The results showed that quinolone derivatives 18 and 19 possess a potent activity against HIV-1 replication with IC50 values of ≥15.20 and 14.26 μM, SI ≤ 6 and >7, respectively.
