Novel aryl carboximidamide and 3-aryl-1,2,4-oxadiazole analogues of naproxen as dual selective COX-2/15-LOX inhibitors: Design, synthesis and docking studies
A series of novel naproxen analogues containing 3-aryl-1,2,4-oxadiazoles moiety (4B-G) and their reaction intermediates aryl carboximidamides moiety (3B-G) was synthesized and evaluated _in vitro_ as dual COXs/15-LOX inhibitors. Compounds 3B-G exhibited superior inhibitory activity than celecoxib as COX-2 inhibitors. Compounds 3B-D and 3G were the most potent COX-2 inhibitors with IC50 range of 6.4 – 8.13 nM and higher selectivity ... Read more

Synthesis, in vitro Antibacterial and in vivo Anti-inflammatory Activity of Some New pyridines
Reaction of 4,6-diamino-3-cyano-2-methylthiopyridine (I) with chloroacetyl chloride or acetic acid afforded the corresponding 6-acetamide derivatives IIa and IIb, respectively. Chloroacetamide derivative IIa reacted with various thiols, secondary amines, potassium thiocyanate, compounds containing active methylene group,1-anilino-2,2-dicyanoethenethiolate, and o-mercatocyanopyridines to give S-alkyl, N-alkyl, thiazole, pyrrole, thiophene, and thienopyridine derivatives, respectively. Antibacterial and anti-inflammatory activities of some new pyridine derivatives were studied. Read more
