Abstract
We herein report the synthesis of a derivative of the natural compound celastrol linked to the antimalarial drug primaquine through an amide obtained by the activation of the carboxylic acid with HOBt/EDC. The chemical structure of the new molecule was fully characterized by proton nuclear magnetic resonance (H-1-NMR), carbon-13 nuclear magnetic resonance (C-13-NMR), heteronuclear single quantum coherence (HSQC), correlation spectroscopy (H-1-H-1-COSY), distortionless enhancement by polarization transfer (DEPT), mass spectrometry, Fourier-transform infrared (FTIR), and ultraviolet (UV) spectroscopies. Computational studies were enrolled to predict the interaction of the synthesized compound with sarco-endoplasmic reticulum (SR) Ca2+ transport ATPase (SERCA), a target of relevance for developing new therapeutics against arthritis. The drug-likeness of the compound was also investigated by predicting its pharmacokinetic properties.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
