  The design, synthesis and evaluation of novel HIV-1 protease inhibitors with high potency against PI-resistant viral strains

  摘要：

  Replacement of the pyridylmethyl moiety in indinavir with a pyridyl oxazole yielded HIV-1 protease inhibitors (PI) with greatly improved potency against PI-resistant HIV-1 strains. A meta-methoxy group on the pyridyl ring and a gem-dimethyl methyl linkage afforded compound 10 with notable in vitro antiviral activity against HIV-1 viral strains with reduced susceptibility to the clinically available PIs. Compound 10 also demonstrated favorable in vivo pharmacokinetics in animal models. (C) 2003 Elsevier Ltd. All rights reserved.

  A process for preparing &ggr;-hydroxy-4-[[2-oxazolyl]alkyl]-&agr;-[(cyclo)alkyl- or aryl- or heteroaryl-substituted methyl]-2-[[(un)substituted alkyl]aminocarbonyl]-1-piperazinepentanamides is disclosed. The piperazinepentanamides are useful as HIV protease inhibitors. A process for making a 4-[[2-oxazolyl]alkyl]-2-[[(un)substituted alkyl]aminocarbonyl]piperazine by treating a ketoamide precursor with fuming sulfuric acid in the presence of polyphosphoric acid is also disclosed. In addition, a process for enhancing the optical purity of 4-[[2-oxazolyl]alkyl]-2-[[(un)substituted alkyl]aminocarbonyl]-piperazines via the formation 2-naphthalenesulfonic acid crystal salts thereof is disclosed, as well as a method for purifying 2-naphthalenesulfonic acid.

  本发明公开了一种制备&ggr;-羟基-4-[[2-噁唑基]烷基]-&agr;-[(环)烷基-或芳基-或杂环芳基取代的甲基]-2-[[(非)取代的烷基]氨基甲酰-1-哌嗪戊酰胺的方法。哌嗪戊酰胺可用作HIV蛋白酶抑制剂。本发明还公开了一种通过在聚磷酸存在下用浓硫酸处理酮酰前体制备4-[[2-噁唑基]烷基]-2-[[(非)取代的烷基]氨基甲酰哌嗪的方法。此外，本发明还公开了一种通过形成2-萘磺酸晶体盐来增强4-[[2-噁唑基]烷基]-2-[[(非)取代的烷基]氨基甲酰哌嗪的光学纯度的方法，以及一种纯化2-萘磺酸的方法。

  A general procedure was developed to prepare alpha-BOC-aminoketones in good yields from alpha-BOC-amino Weinreb amides containing an exchangeable amino proton. By first deprotonating this amino group using 1 equiv. of a simple alkyl Grignard base, only a stoichiometric amount, rather than a large excess, of the nucleophile was needed to prepare the ketone. This procedure is therefore more economical to run and the purification is easier. (C) 2002 Elsevier Science Ltd. All rights reserved.
