Oxadiazole-substituted naphtho[2,3- b ]thiophene-4,9-diones as potent inhibitors of keratinocyte hyperproliferation. Structure−activity relationships of the tricyclic quinone skeleton and the oxadiazole substituent
3-b]thiophene-4,9-diones were synthesized in which the tricyclic quinone skeleton was systematically replaced with simpler moieties, such as structures with fewer rings and open-chain forms, while the oxadiazole ring was maintained. In addition, variants of the original 1,2,4-oxadiazole ring were explored. Overall, the complete three-ring quinone was essential for potent suppression of human keratinocyte

The structurally conserved lipopolysaccharide core region of many Gram-negative bacteria is composed of trisaccharides containing 4-O-phosphorylated l-glycero-d-manno-heptose (l,d-Hep) units, which act as ligands for antibodies and lectins. The disaccharides Glc-(1→3)-Hep4P Hep-(1→3)-Hep4P and Hep-(1→7)-Hep4P and the branched trisaccharide Glc-(1→3)-[Hep-(1→7)]-Hep4P, respectively, have been synthesized

mebendazole.10 Similarly, benzoxazole is the core ring structure in the non-steroidal anti-inflammatory drug flunoxaprofen,11 while the benzothiazole unit is found in zopolrestat12 and riluzole,13 which are used to treat diabetes. Current strategies to prepare these ring systems involve oxidative cyclizations of Schiff bases,14–22 metal-catalyzed amide cyclizations23–25 and reaction of o-substituted
