5-Fluorouracil (5-FU) is the first rationally designed antimetabolite, which achieves its therapeutic efficacy through inhibition of the enzyme thymidylate synthase (TS), which is essential for the synthesis and repair of DNA. However, prolonged exposure to 5-FU induces TS overexpression, which leads to 5-FU resistance in cancer cells. Several studies have(More)
Muscarinic acetylcholine receptors contain two distinct ligand binding sites, i.e. the orthosteric site for acetylcholine and other conventional ligands, and an allosteric site located at the entrance of the ligand binding pocket. We used a set of allosteric agents to probe whether muscarinic M2 receptors whose orthosteric site is occupied by an agonist(More)
