De Souza, Fayene Zeferino Ribeiro [UNESP]; De Almeida, Amanda Cosmo [UNESP]; Ferreira, Patrícia Osorio [UNESP]; Fernandes, Richard Perosa [UNESP]Made available in DSpace on 2022-04-28T19:50:00Z (GMT). No. of bitstreams: 0 Previous issue date: 2022-01-01; Quercetin (QUE) is a nutraceutical compound that exhibits pharmacological properties such as antioxidant, cardioprotective, anti-ulcer, and anti-inflammatory effects. Although QUE is well-known for its benefits, its efficacy is limited due to low solubility. Thus, cocrystallization acts as an interestin...

Ferreira, Patrícia Osório [UNESP]; de Moura, Aniele [UNESP]; de Almeida, Amanda Cosmo [UNESP]; dos Santos, Éverton Carvalho [UNESP]Made available in DSpace on 2021-06-25T10:25:15Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-01-01; Cocrystallization is a very efficient strategy to improve the physicochemical properties of bioactive agents. A new norfloxacin (NOR)–saccharin cocrystal and a cocrystal–solvate were synthesized through the mechanochemical method (neat and liquid-assisted grinding), and the characterization was performe...
