Novel therapeutics to overcome the toxic effects of organophosphorus (OP) chemical agents are needed due to the documented use of OPs in warfare (e.g. 1980-1988 Iran/Iraq war) and terrorism (e.g. 1995 Tokyo subway attacks). Standard OP exposure therapy in the United States consists of atropine sulfate (to block muscarinic receptors), the(More)
AIMS Due to pralidoxime chloride's (2-PAM) positive charge, it's penetration through the blood brain barrier (BBB) and reactivation of organophosphate (OP) inhibited central nervous system (CNS) acetylcholinesterase (AChE) is poor. The results of CNS inhibited AChE are seizures. Pro-2-PAM (1-methyl-1,6-dihydropyridine-2-carbaldoxime), a pro-drug of 2-PAM,(More)
Given the impressive success of Gilead's Sofosbuvir, many laboratories, including ours, have explored the unique 2'-sugar modification (2'-Me, 2'-F) of nucleoside analogues in the hopes of exploiting the biological activity that this unique modification has imparted to the nucleoside scaffold. In that regard, we have combined our tricyclic "expanded" purine(More)
The chemotherapeutic drug Gemcitabine, 2',2'-difluoro-2'-deoxycytidine, has long been the standard of care for a number of cancers. Gemcitabine's chemotherapeutic properties stem from its 2',2'-difluoro-2'-deoxyribose sugar, which mimics the natural nucleoside, but also disrupts nucleic acid synthesis, leading to cell death. As a result, numerous analogues(More)
