Naproxenylamino acid derivatives: Design, synthesis, docking, QSAR and anti-inflammatory and analgesic activity

Abstract

This work aimed to design and synthesize a safe nonsteroidal anti-inflammatory drug NSAIDs agent based on Naproxen scaffold. The structure of compounds 6-21 established on the basis of different spectral data. Anti-inflammatory and analgesic profile were examined for synthesizing compounds. The compounds 6 and 17 have shown a higher anti-inflammatory potency than Naproxen. The compounds 16, 19 and 21 have exhibited the highest analgesic potency compared to other tested compounds. The synthesized compounds have shown negligible ulcerogenic effect and may be considered as safer drugs than naproxen for treating inflammatory conditions. The molecular docking against COX-2 was performed, it verified that compound 6, 17 show stronger interactions with COX-2. This may result in a better inhibitory effect on COX-2. The best generated QSAR model shows correlation between BCUT_SMR_3 and vsurf_Wp6 with biological activity. ADMET in silico showed that these compounds are a good oral bioavailability without observed carcinogenesis affect.
