Abstract 789: Multi-targeted novel 5-substituted pyrrolo[3,2-d]pyrimidines with tumor-selective targeting and inhibition of cytosolic de novo purine biosynthesis and mitochondrial one-carbon metabolism
Abstract:One-carbon (C1) metabolism supports a number of physiological and pathophysiological processes ranging from stem cell renewal to cancer progression. Clinically used antifolates are transported into both tumor and normal cells by the ubiquitously expressed reduced folate carrier (RFC). Uptake of targeted agents via tumor-specific folate receptors (FRs) over RFC would permit tumor-selectivity, while limiting dose-limiting toxicities associated with standard chemotherapy. Serine catabolism in mitochondria is the … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
