Discovery of dihydrobetulinic acid as a potent small molecule CD73 inhibitor
{{output}}
Betulinic acid (BA) is a pentacyclic triterpene compound with various biological activities. Herein, we designed and synthesized a series of dihydrobetulinic acid (DHBA) and its derivatives for the discovery of potent ecto-5'-nucleotidase (CD73) inhibitors. B... ...
