    • Bio Activity:

      Calyculin A is a potent inhibitor of the catalytic subunit of type-2A phosphatase, with IC50 values of 0.5 to 1 nM. ;Target: protein phosphataseCalyculin A induces contraction in smooth muscle fibers. With the catalytic subunit of protein phosphatase type-1, calyculin A is an effective inhibitor , IC50 values for calyculin A is about 2 nM and. The endogenous phosphatase of smooth muscle myosin B was inhibited by calyculin A with IC50 values of 0.3 to 0.7 nM for calyculin A. The partially purified catalytic subunit from myosin B had IC50 values of 0.7 nM for calyculin A. MedChem Express HY-18983
