  Irreversible Inhibition of the HIV-1 Protease:  Targeting Alkylating Agents to the Catalytic Aspartate Groups

  摘要：

  Irreversible inhibition of the HIV-1 protease by agents that specifically alkylate its catalytic aspartate residues is a potentially useful approach for circumventing the evolution of HIV strains that are resistant to protease inhibitors. Five haloperidol- and two FMOC-based epoxides of differing reactivities have been synthesized and tested as irreversible inhibitors of the HIV-1 protease (HIV-1 PR). Of these, two trisubstituted epoxides, a cis-1,2- disubstituted epoxide, a 1,1-disubstituted epoxide, and a monosubstituted epoxide function as irreversible inhibitors, but two trans-1,2-disubstituted epoxides do not. The most effective of the epoxides (6) inactivates HIV-1 PR with K-inact = 65 mu M and V-inact = 0.009 min(-1). 1,2-Epoxy-3-(p-nitrophenoxy)propane (EPNP), a nonspecific inactivating agent for aspartyl proteases, has been used to validate a protocol for establishing the stoichiometry and site of protein alkylation. Mass spectrometric analysis of the inactivated enzyme shows that one molecule of either EPNP or the cyclic 1,2-disubstituted epoxide 6 is covalently bound per HIV-1 PR dimer. Mass spectrometric sequencing of labeled proteolytic peptides shows that both inhibitors are covalently bound to a catalytic aspartate residue. The covalent binding of three alpha,beta-unsaturated ketone derivatives of haloperidol has been similarly examined. Analysis of HIV-1 PR inactivated by these agents establishes that they bind covalently to the two cysteines and the N-terminal amino group but not detectably to the catalytic aspartate residues. The results indicate that aspartate-targeted inactivation of HIV-1 PR depends on (a) matching the reactivity of the alkylating functionality to that of the aspartates, preferably by exploiting the two-aspartate catalytic motif of the protease to activate the alkylating agent, and (b) appropriate positioning of the alkylating functionality within the active site. These requirements are readily met by a monosubstituted, 1,1-disubstituted, or cyclic cis-1,2-disubstituted epoxide but not by trans-1,2-disubstituted epoxides or alpha,beta-unsaturated ketones.

  环丙烯基乙烯基芳烃的分子内 Diels-Alder 反应：获得苯正卡烷衍生物

  摘要：

  分子内狄尔斯-阿尔德乙烯基芳烃反应 (IMDAV) 是一种 [4 + 2] 环加成反应，采用苯乙烯衍生物作为共轭二烯，其反应性差是由于所需的芳香性损失造成的，而芳香性通过随后的 [1,3]-H 转移来恢复。在此，我们描述了使用环丙烯作为亲二烯体，利用其应变能来驱动 IMDAV 反应。苯正卡烷支架的形成具有良好的产率、优异的立体选择性和广泛的功能耐受性。理论计算和核磁共振研究揭示了重要的机制见解。

  Isomerization of oxime derivatives was researched in detail to find out the methods for the syn-anti isomerization of O-substituted oximes. Based on these findings were developed simple methods for the preparation of aza-heterocycles from both stereo­isomers of oximes. Quinolines were synthesized from β-aryl ketone oximes by treatment with trifluoroacetic anhydride and 4-chloranil. γ,δ-Unsaturated O-methoxyacetyloximes were transformed to 2H-dihydropyrroles by reaction with methoxy-acetic acid.

  A method based on hydroamination mediated by inorganic base was developed for the synthesis of cyclic nitrones from alkenyl oximes. DFT calculations of the reaction pathway suggested that this hydroamination could proceed through an unprecedented nucleophilic amination of the unactivated alkene by the oxime nitrogen atom. The transition state of this reaction is stabilized by an ionic interaction between
