NSAID-Derived Selenazoles/Thiazoles as Potential Cancer TherapeuticsID# 2014-4259
A cyclic Se-Aspirin compound, AS-10, was identified through extensive SAR studies focused on Se-NSAID hybrid compounds based on potency determination, toxicity, and drug-likeness. AS-10 is selectively toxic to cancer cells in vitro, demonstrating high efficacy across different PDAC cell lines at 48h, with IC50 ranging from 0.7-2.5 µM compared to Gemcitabine (Gem), which has an IC50 >500 µM. AS-10 inhibits tumor growth without apparent systemic toxicity by inducing apoptosis in various cancer cells, especially PDAC. Experimental evidence shows a synergistic effect with Gem observed both in cell culture and xenograft mouse models in both male and female mice.
Application & Market Utility
Pancreatic cancer is one of the deadliest cancers, with a median survival of less than one year and a five year survival rate of less than 10%. Most patients do not have symptoms in earlier stages – 80% of pancreatic cancers are metastatic at the time of diagnosis. Given this dire prognosis, AS-10 may address a significant unmet need, aiming to improve outcomes for advanced pancreatic cancer patients through the use of a novel, small molecule therapeutic compound as a monotherapy or in combination with the current standard of care.
