Asymmetric cyclopropanation of styrenes by tert-butyl diazoacetate followed by ester hydrolysis and Curtius rearrangement gave a series of tranylcypromine analogues as single enantiomers. The o,- m- and p-bromo analogues were all more active than tranylcypromine in a LSD1 enzyme assay. The m- and p-bromo analogues were micromolar growth inhibitors of the(More)
Three diastereomers of burkholdac B were prepared by total synthesis, enabling the full stereochemical assignment of the natural product. It is proposed that burkholdac B is identical to thailandepsin A independently isolated by Cheng from the same strain of Burkholderia thailandensis . Burkholdac B is the most potent among depsipeptide histone deacetylase(More)
The total synthesis of largazole and four analogues is reported. All analogues were nanomolar HDAC inhibitors. The antiproliferative activity is driven by lipophilicity and cell permeability. In murine liver homogenates, largazole is rapidly metabolized (half-life ≤5 min) to the thiol which has a half-life of 51 min.
We report a series of tranylcypromine analogues containing a fluorine in the cyclopropyl ring. A number of compounds with additional m- or p-substitution of the aryl ring were micromolar inhibitors of the LSD1 enzyme. In cellular assays, the compounds inhibited the proliferation of acute myeloid leukemia cell lines. Increased levels of the biomarkers(More)
82 Background: Hormonal strategies to inhibit androgen receptor (AR) signalling remain inadequate and so novel approaches are urgently required. Lysine (K)-specific demethylase 1A (LSD1), is an epigenetic AR co-activator which modifies chromatin structure through de-methylation of histone H3 lysine 9 at androgen response elements to activate transcriptional(More)
