Chebulinic Acid is a naturally occurring ellagitannin isolated from T. chebula with various biological activities. It acts as an inhibitor of protein
tyrosine phosphatase non-receptor 9 (PTPN9) and PTPN11 with IC50s of 34 and
37 nM, respectively. It also inhibits M. tuberculosis DNA gyrase, SMAD-3 phosphorylation, and H+ K+-ATPase activity.
