  Cyclopeptidic inactivators for chymotrypsin-like proteinases

  摘要：

  Cyclopeptides containing a functionalized meta-aminobenzoic acid residue (m-aB[CH2X] with X = OC6H5, OAc, Br, Cl) linked to a tetraglycyl-phenylalanyl sequence, have been synthesized in solution. A phenyl ether group has been used during chain elongation and cyclisation, and then cleaved by treatment with HBr/HOAc to give the corresponding bromide, from which the acetate and the chloride have been obtained. The functionalized aminobenzoic acid residues possess a latent quinonimmonium methide electrophilic function, and these cyclopeptides are potential ''suicide'' substrates of chymotrypsin-like proteases. The cyclopeptides with X = Br or Cl irreversibly inhibit alpha-chymotrypsin (k(inact)/K(I) = 180 M-1min-1 for X = Cl). The compounds with poorer leaving groups X = OAc or OC6H5 are devoid of inactivating effect and only behave as substrates of this enzyme (k(cat)/K(M) = 31 800 M-1min-1 and 120 000 M-1min-1, respectively).
