SR CA(2+)-ATPASE IN THE HNE2 STATE COMPLEXED WITH THE THAPSIGARGIN DERIVATIVE BOC-12ADT.

Overview

An analysis of the binding of the, 8-O-N-tert-butoxycarbonyl-12-aminododecanoyl derivative of, 8-O-debutanoylthapsigargin to the target molecule, the SERCA pump, has, revealed the importance of the length and flexibility of the side chain, attached to O-8. Based on the analysis a series of analogues to the, 2-unsubstituted analogue trilobolide has been constructed and shown to be, equipotent with thapsigargin as SERCA inhibitors. Only the, 12-Boc-aminododecaonoyl derivative, however, was found to be apoptotic.
