As STAT3 has been validated as an anticancer target, its inhibitors have been shown to possess therapeutic promise for the treatment of human cancers. To identify novel and selective STAT3 inhibitors, a virtual screening based on the STAT3 SH2 domain was performed and a small molecule, 2-phenylquinoline-4-carboxylic acid (5a), with an inhibition constant Ki value of 17.53 μM to STAT3 was discovered
The quinoline scaffold is an important class of heterocyclic compounds that possesses diverse chemotherapeutic activities. Thus, the 2-phenylquinoline-4-carboxamide derivatives containing a variety of moieties, such as 2-(2-furanyl)-1,3,4-oxadiazole, N-(2-methylphenyl)-4-(3-pyridinyl)-2-pyrimidinamine, 4,4'-bithiazole, purine, adamantine and resorcinol, have been designed and synthesized via Suzuki coupling, acid-base coupling and other typical reactions.
