• Inhibition of HIV-1 Replication by Disruption of the Processing of the Viral Capsid-Spacer Peptide 1 Protein
  申请人：SALZWEDEL Karl

  公开（公告）日：2008-09-25

  Inhibition of HIV-1 replication by disrupting the processing of the viral Gag capsid (CA) protein (p24) from the CA-spacer peptide 1 (SP1) protein precursor (p25) is disclosed. Amino acid sequences containing a mutation in the Gag p25 protein, with the mutation resulting in a decrease in the inhibition of processing of p25 to p24 by dimethylsuccinyl betulinic acid or dimethylsuccinyl betulin, polynucleotides encoding such mutated sequences and antibodies that selectively bind such mutated sequences are also included. Methods of inhibiting, inhibitory compounds and methods of discovering inhibitory compounds that target proteolytic processing of the HIV Gag protein are included. In one embodiment, such compounds inhibit the interaction of the HIV protease enzyme with Gag by binding to Gag rather than to the protease enzyme. In another embodiment, viruses or recombinant proteins that contain mutations in the region of the Gag proteolytic cleavage site can be used in screening assays to identify compounds that target proteolytic processing.

  本文揭示了通过破坏病毒Gag外壳蛋白（CA）从CA-spacer肽1（SP1）蛋白前体（p25）中的处理来抑制HIV-1复制的方法。包括含有Gag p25蛋白中突变的氨基酸序列，该突变导致二甲基琥珀酰基白桦酸或二甲基琥珀酰基白桦醇对p25到p24的处理抑制减少，编码这种突变序列的多核苷酸以及选择性结合这种突变序列的抗体。还包括抑制，抑制性化合物和发现靶向HIV Gag蛋白的蛋白酶加工的抑制性化合物的方法。在一种实施方式中，这些化合物通过结合Gag而不是蛋白酶酶来抑制HIV蛋白酶酶与Gag的相互作用。在另一种实施方式中，包含在Gag蛋白酶剪切位点区域中的突变病毒或重组蛋白可以用于筛选测定，以识别靶向蛋白酶加工的化合物。
