  Benzoylalanine-Derived Ketoamides Carrying Vinylbenzyl Amino Residues:  Discovery of Potent Water-Soluble Calpain Inhibitors with Oral Bioavailability

  摘要：

  Novel benzoylalanine-derived ketoamides were prepared and evaluated for calpain I inhibition. Derivatives carrying vinylbenzyl amino residues in the P-2-P-3 region inhibited calpain in nanomolar concentrations and thus represent a novel class of nonpeptidic calpain inhibitors. Selected examples exhibited an improved pharmacokinetic profile including improved water-solubility and metabolic stability. In particular, these calpain inhibitors showed oral bioavailability in rats as demonstrated by N-(1-benzyl-2-carbamoyl-2-oxoethyl)-2-[E-2-(4-diethylaminomethylphenyl)ethen-1-yl]benzamide (5d). The closely related derivative N-(1-carbamoyl-1-oxohex-1-yl)-2-[E-2-(4-dimethylaminomethylphenyl)-ethen-1-yl]benzamide (5b) was evaluated for neuroprotective efficacy after experimental traumatic brain injury in a fluid percussion model in rats. When administered after injury, 5b reduced the number of damaged neurons by 41%, and this result would be in line with the suggested neuroprotective efficacy of calpain inhibition.

• Reactions of Nitroalkenes with Nitroalkanes or Sulfur Ylides Catalyzed by Amine-Thiourea Bifunctional Polymeric Organocatalysts
  作者：Patrick Toy、Jinni Lu

  DOI：10.1055/s-0031-1289900

  日期：2011.12

  Non-cross-linked and cross-linked bifunctional polystyrenes bearing both amine and thiourea groups have been synthesized and used as organocatalysts in reactions between nitroalkenes and nitroalkanes or sulfur ylides. Control experiments using monofunctional polymers with only either amine or thiourea groups attached indicated that both functional groups were essential for efficient catalysis of the reactions studied. The non-cross-linked polystyrene was soluble in typical organic solvents and was used as a homogeneous catalyst, while the cross-linked polystyrene was used as a heterogeneous catalyst.

  具有氨基和硫脲基团的双功能非交联和交联聚苯乙烯已被合成，并作为有机催化剂用于硝基烯烃与硝基烷烃或硫叶立德之间的反应。通过仅附着胺或硫脲基团的单功能聚合物的对照实验表明，两种功能基团对于所研究反应的高效催化都至关重要。非交联聚苯乙烯可溶于典型的有机溶剂，被用作均相催化剂，而交联聚苯乙烯则用作非均相催化剂。
