Methyl protodioscin (NSC-698790, Smilax saponin B) is a multi-target, selective, steroidal diglycoside inhibitor with antitumor activity that induces cell cycle arrest. The mechanism of action of Methyl protodioscin is complex, involving the induction of G2/M cell cycle arrest, regulation of the Bcl-2/Bax apoptotic pathway, inhibition of the Akt1/c-Myc axis and MAPK/ERK signaling, while simultaneously downregulating ADAM15 and inducing FOXO1 to reduce cholesterol synthesis. It also inhibits the JNK/c-Jun pathway, reducing the production of inflammatory factors (IL-6, TNF-alpha). Methyl protodioscin exhibits significant antitumor (inhibiting proliferation, migration, invasion, and inducing apoptosis), anti-inflammatory, and anti-restenosis activities. Methyl protodioscin can be used in research on lung cancer, prostate cancer, pancreatic cancer, and other tumors, as well as inflammatory diseases such as airway inflammation and enteritis[1][2][3][4][5][6][7].
