Abstract EN
This study was aimed to design novel diclofenac hydrazones having anti-inflammatory and analgesic activity with gastric sparing effect.
A new series of 2-[2-(2,6-dichloroanilino)phenyl]-N’-[(substituted phenyl) methylidene] acetohydrazide derivatives (1−14) were synthesized and evaluated for their anti-inflammatory, analgesic, and ulcerogenic activity.
The compounds were identified and confirmed by elemental analysis and spectral data.
During anti-inflammatory activity by carrageenan-induced paw edema method, compounds (2, 3, 7, 8, 11, and 13) were found to be most promising.
Compounds 3, 8, and 13 have been found to have significant analgesic activity compared to the reference drug diclofenac in analgesic activity by both the hot plate method and acetic acid-induced writhing method.
The compounds which presented highly significant anti-inflammatory and analgesic activity were further tested for their ulcerogenic activity.
Compounds 3 and 8 showed maximum ulcerogenic reduction activities.
Compound 8 was found to have LD50 of 168 mg/kg.
Compound 8 with 3,5-dimethoxy-4-hydroxyphenyl substitution was found to be the most promising anti-inflammatory and analgesic agent with gastric sparing activity.
Molecular docking of compounds was performed for COX−1/COX−2 binding site.
Lead compound 8 showed better binding affinities of −9.4 kJ/mol with both COX-1 and COX-2 as compared to the standard drug, diclofenac with binding affinities of −6.6 kJ/mol and −8.1 kJ/mol for COX−1 and COX−2, respectively.
