STAT3 belongs to the signal transducers and activators of transcription (STAT) family. It has been demonstrated that STAT3 is constitutively activated in many tumors, playing a role in carcinogenesis and tumor progression. For this reason, it has being considered a potential target for cancer therapy. In this context, we have designed, synthesized and evaluated 1,​4-​dimethyl-​carbazole derivs., targeting the STAT3 protein. Moreover, MTT assay performed on A375 and HeLa, showed significant antiproliferative activity of some of synthesized compds. (3-​5)​. The same compds. (3-​5) considerably reduced STAT3 expression, as demonstrated by Western blot anal. Our multidisciplinary approach shows that 1,​4-​dimethyl-​carbazoles are potential building blocks to develop more affinity ligands of STAT3.

Abstract

STAT3 belongs to the signal transducers and activators of transcription (STAT) family. It has been demonstrated that STAT3 is constitutively activated in many tumors, playing a role in carcinogenesis and tumor progression. For this reason, it has being considered a potential target for cancer therapy. In this context, we have designed, synthesized and evaluated 1,​4-​dimethyl-​carbazole derivs., targeting the STAT3 protein. Moreover, MTT assay performed on A375 and HeLa, showed significant antiproliferative activity of some of synthesized compds. (3-​5)​. The same compds. (3-​5) considerably reduced STAT3 expression, as demonstrated by Western blot anal. Our multidisciplinary approach shows that 1,​4-​dimethyl-​carbazoles are potential building blocks to develop more affinity ligands of STAT3.
