Abstract: Removal of each of the acyl groups of thapsigargin at O-3, O-8 and O-10 significant reduces the affinity of the inhibitors to the SERCA1a pump. Replacement of the acyl groups at O-3 and O-10 with flexible residues could be performed with only a minor decrease of the affinity, whereas introduction of voluminous stiff residues caused dramatic reduction of the affinity. The results can be rationalized on the basis of the interactions of thapsigargin with the SERCA1a pump as revealed from 3D X-ray structural models of thapsigargin bound to the SERCA1a. In conclusion the results confirm and elaborate the previously suggested pharmocophore model of thapsigargin.
