Synthesized Depside Molecules Suppress the Progression of Colorectal Cancer by Binding VDAC1/PHB/MMP9 Being at the Crossroads of Stemness, Motility, Apoptosis, and Metabolism. [PDF]
MedComm (2020)This study suggests that newly synthesized depside compounds suppress the progression of colorectal cancer by directly targeting VDAC1/PHB/MMP9. Especially, SB4 demonstrated significant bioavailability and successfully suppressed the tumor growth. ABSTRACT Lichen secondary metabolites have shown potential in cancer therapy, but strategies to enhance ...
