Metabolic dysfunction-associated fatty liver disease (MAFLD) presents a significant global health challenge, characterized by the accumulation of fat and impacting considerable portion worldwide population. Despite its widespread occurrence, effective treatments for MAFLD are limited. The liver-specific isoform pyruvate kinase (PKL) has been identified as promising target developing therapies. Urolithin C, an allosteric inhibitor PKL, shown potential in preliminary studies. Expanding upon...

A highly efficient, regioselective, and environmentally friendly method has been developed for water-mediated synthesis of 2,3,6-trisubstituted pyridines 5,6,7,8-tetrahydroquinolines. The introduced allows easy preparation various polysubstituted 5,6,7,8-tetrahydroquinolines via domino reaction an enolizable ketone, ammonia enones derived from different Mannich bases in mild conditions. Montmorillonite K-10 promoted this one-pot three-component gave both new known good yields. protocol...

An efficient synthetic route has been described for the alkylation of 1$H$-indole, 1$H$-benzimidazole, and 1$H$-benzotriazole. This approach features heteroaromatics through in situ generated enones from ketonic Mannich bases under metal-free conditions. A series alkylated have synthesized via K10 catalyzed reactions these with a variety bases. Environmentally benign catalyst, water-mediated mild reaction conditions, synthesis products are advantages this method.
