  Deracemisation of aryl substituted α-hydroxy esters using Candida parapsilosis ATCC 7330: effect of substrate structure and mechanism

  摘要：

  Candida parapsilosis ATCC 7330 was found to be an efficient biocatalyst for the deracemisation of aryl alpha-hydroxy esters (65-85% yield and 90-99% ee). A variety of aryl and aryl substituted alpha-hydroxy esters were synthesized to reflect steric and electronic effects on biocatalytic deracemisation. The mechanism of this biocatalytic deracemisation was found to be stereoinversion. (c) 2005 Elsevier Ltd. All rights reserved.

  commercially available racemic mixtures or l‐amino acids. These whole‐cell systems couple Proteus mirabilis l‐amino acid deaminase with an engineered aminotransferase that displays native‐like activity towards d‐phenylalanine, which we generated from Bacillus sp. YM‐1 d‐amino acid aminotransferase. Our cascades are applicable to preparative‐scale synthesis and do not require cofactor‐regeneration systems

  phenylalanine ammonia lyase (PAL) amination with a chemoenzymatic deracemization (based on stereoselective oxidation and nonselective reduction). A simple high‐throughput solid‐phase screening method has also been developed to identify PALs with higher rates of formation of non‐natural D‐phenylalanines. The best variants were exploited in the chemoenzymatic cascade, thus increasing the yield and ee value

  Psammaplin A (11c) is a marine metabolite previously reported to be a potent inhibitor of two classes of epigenetic enzymes: histone deacetylases and DNA methyltransferases. The design and synthesis of a focused library based on the psammaplin A core has been carried out to probe the molecular features of this molecule responsible for its activity. By direct in vitro assay of the free thiol generated upon reduction of the dimeric psammaplin scaffold, we have unambiguously demonstrated that 11c functions as a natural prodrug, with the reduced form being highly potent against HDAC1 in vitro (IC50 0.9 nM). Furthermore, we have shown it to have high isoform selectivity, being 360-fold selective for HDAC1 over HDAC6 and more than 1000-fold less potent against HDAC7 and HDAC8. SAR around our focused library revealed a number of features, most notably the oxime functionality to be important to this selectivity. Many of the compounds show significant cytotoxicity in A549, MCF7, and W138 cells, with the SAR of cytotcodcity correlating to HDAC inhibition. Furthermore, compound treatment causes upregulation of histone acetylation but little effect on tubulin acetylation. Finally, we have found no evidence for 11c functioning as a DNMT inhibitor.
