  Cantharidin and its analogues have been of considerable interest as potent inhibitors of the serine/threonine protein phosphatases 1 and 2A (PP1 and PP2A). However, limited modifications to the parent compounds is tolerated. As part of an ongoing study we have developed a new series of cantharidin analogues, the cantharimides. Inhibition studies indicate that cantharimides possessing a D- or L-histidine, are more potent inhibitors of PP1 and PP2A (PP1 IC50 = 3.22 +/- 0.7 muM; PP2A IC50 = 0.81 +/- 0.1 muM and PP1 IC50 = 2.82 +/- 0.6 muM; PP2A IC50 = 1.35 +/- 0.3 muM, respectively) than norcantharidin (PP1 IC50 = 5.31 +/- 0.76 muM; PP2A IC50 = 2.9 +/- 1.04 muM) and essentially equipotent with cantharidin (PP1 IC50 = 3.6 +/- 0.42 muM; PP2A IC50 = 0.36 +/- 0.08 muM). Cantharimides with non-polar or acidic amino acid residues are only poor inhibitors of PP1 and PP2A. (C) 2001 Elsevier Science Ltd. All rights reserved.

  L- and D-histidine norcantharimide was showed significant PP2A inhibitors effect. They were synthesized through a highly efficient combinatorial approach , to a solution of norcantharidin and L-histidine in 95 % EtOH under temperature affords L-histidine norcantharimide in 97 % yield. L-histidine norcantharimide was characterized by X-ray. This single crystal was orthorhombic with the space group P2(1)2(1)2(1). One unit cell dimensions were a = 10.1553(4) Å, b = 10.4840(5) Å and c = 12.8749(6) Å, respectively. a = b = g = 90°, Mr = 305.29, V = 1370.77(11) Å3, D = 1.479 Mg/m3, F(000) = 640 and Z = 4. The crystal structure is stabilized by a network of intermolecular hydrogen bonds involving N-H and COO– group.
