The Influence of the Substitution Pattern on the Molecular Conformation of Ureido-1,2,5-oxadiazoles, Related to STAT3 Inhibitors: Chemical Behavior and Structural Investigation
activator of transcription 3 (STAT3) is a protein constitutively activated by aberrant upstream tyrosine kinase activities in a broad spectrum of human solid and blood tumors. Therefore, the availability of drugs affecting STAT3 may have important therapeutic potential for the treatment of cancer. Pursuing our efforts in exploring the influence of the substitutionpattern of the ureido 1,2,5‐oxadiazole
