• Synthesis of symmetrical pseudopeptides as potential inhibitors of the human immunodeficiency virus-1 protease

  It is demonstrated that HIV-1 protease is essential for the assembly and infectivity of the acquired immunodeficiency syndrome (AIDS) virus. This protease is an aspartyl protease with a 2-fold symmetry axis. Potential inhibitors were synthesized and consisted of a spacer linking 2 peptidic chains. They had to satisfy the following constraints: a C-2 symmetry axis, a backbone similar to the peptidic substrates, and side-chains filling the subsites S-n...S'(n). The compounds were synthesized via peptidic synthetic methods and evaluated in an enzymatic test with HIV-1 protease. Several compounds displayed an inhibitory activity at 10 mu M. They possessed the spacers CO, CO-CO, CO-CH2-CHOH-CO and the terminal chain Phe-O-iC(4)H(9). However, the structural-variation-based optimization of these different compounds failed and no potent inhibitors were prepared.

  endo-cis-(2S,3R)-Bicyclo[2.2.1]hept-5-en (norbornene) dicarbonyl unit with a built-in U-architecture has been demonstrated to be an excellent reverse-turn molecular scaffold. A large variety of endo-cis-(2S,3R)-norborneno bispeptides containing almost all of the coded amino acids were synthesized and examined for conformational preferences by H-1 NMR, FT-IR, CD, and X-ray crystallographic studies. While FT-IR and H-1 NMR variable-temperature studies ruled out the presence of any significant amount of intramolecular hydrogen bonding in simple bispeptides (3a-h) (except in Aib bispeptide), the CD studies were clearly in favor of a beta-turn type structure. Single-crystal X-ray studies on Aib, Val and Leu containing norborneno bispeptides (3b-d) provided convincing proof for the presence of reverse-turn conformation. While the interstrand C-alpha-C-alpha' distances (5.2-5.7 Angstrom) were well within the range of those for beta-turn structures, no interstrand intramolecular hydrogen bonding was seen in Val and Leu bispeptides; the Aib bispeptide forms a seven-membered hydrogen-bonded ring, thus, showing that the norbornene (2S,3R)-dicarbonyl template assembles peptide chains in reverse-turn conformation by virtue of its built-in U-shaped architecture at these positions, and hydrogen bonding may not be necessary to stabilize the turn structure. The endo-cis-(2S,3R) orientation of bispeptide chains is essential for turn structure as shown by the crystal structure of trans-(2R, 3R) and trans-(2S,3S) derivative of Val bispeptide wherein the two peptide chains move away from each other with the C-alpha-C-alpha' distance increasing to 7.1-8.2 Angstrom. The norbornene 5,6-double bond was hydrogenated to 5,6-dihydro derivative which showed almost the same CD spectrum as its olefinic analogue. Oxidative cleavage [Ru (VIII)] of the 5,6-double bond in norborneno bispeptides, as demonstrated with Leu bispeptide, afforded novel cyclopentanoid peptide analogues. The promise of norbornene unit as a template for nucleating the formation of two-stranded parallel beta-sheets with minimum structural complexity is shown by the preparation of higher members of norborneno bispeptides with the general structure NBE(Pep)(2) [NBE = endo-cis-(2S,3R)-bicyclo[2.2.1]hept-5-en (norbornene) dicarbonyl unit; Pep = peptide strand with two, three, or four (same or different) amino acid residues]. In H-1 NMR, the high (3)J(HN alpha) values (7.0-9.3 Hz) observed for the amide protons (Table 5) coupled with the presence of medium to strong intrastrand sequential ROE connectivities d(alpha N(i,i+1)) spanning the entire three- or four-residue sequence in the peptide strands of 9a-e and 10 and the exhibition of relatively low-temperature coefficients (d delta/dT = -0.2 to -3.4 ppb/K) for amide protons in DMSO-d(6) solvent (Table 4) clearly suggested that hydrogen-bonded beta-sheet conformers dominate the population. FT-IR and CD studies provided further support for parallel beta-sheet structures. A particularly unique feature of the norborneno bispeptides is their strong tendency to self-assemble in the solid state.Thus, while endo-cis-(2S,3R)-Aib bispeptide (3b) forms 16-membered hydrogen bonded centrosymmetric dimers, the half-ester half-acid and the dicarboxylic acid derivatives of 3b self-assemble to form highly ordered hydrogen-bonded molecular ribbons. The Val and Leu cis-(2S, 3R)-bispeptides organize into hydrogen-bonded chains and the trans isomer of Val bispeptide self-assembles into hydrogen-bonded beta-sheet ribbon.
