摘要
This study focused on the recent synthesis of new compounds from aryl propionic acid derivatives compared to naproxen. The present study aimed to investigate the safety and efficiency of the new derivatives in improving analgesic effects and reducing adverse effects via modifying its chemical structure by adding new functional groups. The new compounds were characterized, and evaluate their pharmacodynamic effects. The analysis and characterization of new compounds were by 1HMNR and FT-IR spectrum. The investigation of the adverse effect after 5 days of remedy with 20 mg/kg daily administered with naproxen derivatives to the healthy male albino mice (25-30 g) for analgesic activity using the hot plate method. Mice were parted into 5 groups, consisting of the control group and 4 groups that administered naproxen or derivatives of aryl propionic acid (E, H, D1 and D2). The main tests are done by a hot plate, biochemical, macroscopic, and microscopic inspection. The results confirmed that the new drugs have potent analgesic activity. The results showed that mice administered with D1 expressed less ulcerative effect than parent naproxen, H, E and ethanol. Moreover, the number of lesions was significantly less in the D2 group, while D1-treated mice recorded no evidence of ulcers or hemorrhage in their stomachs after being examined under a dissecting microscope. The study concluded that the new D1 derivative is a compound worthy of research and future clinical applications due to its relatively high efficacy and low adverse effects compared to other derivatives prepared and tested in this study.
