Repositioning of Montelukast to inhibit proliferation of mutated KRAS pancreatic cancer through a novel mechanism that interfere the binding between KRAS and GTP/GDP.

Pancreatic cancer is one of the most lethal cancer types with 5-year survival rate of ∼10.8%. Various KRAS mutations exist in ∼85% pancreatic cancer cell lines.

Repositioning Lomitapide to block ZDHHC5-dependant palmitoylation on SSTR5 leads to anti-proliferation effect in preclinical pancreatic cancer models.

Palmitoylation of proteins plays important roles in various physiological processes, such as cell proliferation, inflammation, cell differentiation etc. However, inhibition of protein palmitoylation has led to few new drugs to date. ZDHHC5 serves as a key enzyme to catalyze palmitoylation on SSTR5 (a proven anti-proliferation receptor in pancreatic cells).

Magnetic Co-based carbon materials derived from core-shell metal-organic frameworks for organic contaminant elimination with peroxymonosulfates.

The exploitation of highly efficient and reusable catalysts based on peroxymonosulfate (PMS) activation has attracted considerable attention in the environmental catalysis field. Herein, Co-doped graphitic carbon (Co-GC) on nitrogen-doped carbon (NC@Co-GC) was constructed and first employed as an efficient heterogeneous catalyst to activate PMS for the removal of organic contaminants. Coupled with only 0.
