  Synthesis and Biological Evaluation of 12-Aminoacylphorboids

  摘要：

  Spurred by the paradoxical anti-inflammatory activity of some aminoacylphorbol derivatives, the naturally occuring and epimeric N,N-dimethylvalinoyl-4 alpha-4-deoxyphorbol derivatives 3b and 3d have been prepared from 4 alpha-4-deoxyphorbol (3e), a byproduct of the isolation of phorbol from Croton oil and a phorboid polyol so far largely overlooked in terms of biological activity. The configuration of the side chain stereocenter was confirmed for both natural products and to investigate the side chain structure-activity relationships within this class of compounds, their corresponding, N,N-dimethylglycinate (3g) and nor (3h) and di-nor derivatives (3i, 3j) were also prepared. By using a PKC-sensitive model of, HIV-1 latency (activation of HIV- gene expression in Jurkat-LAT-GFP cells), it was found that both 3b and 3d can activate PKC-dependent responses, while a series of experiments with isoform-spcefic PKC inhibitors showed that these compounds target PKC alpha and -delta. Both N,N-dimethylation and the presence of side chain alpha-substitution were critical for activity. Selective PKC binding, rather than COX inhibition, might explain the paradoxical anti-inflammatory activity of extracts containing aminoacylphorboids in the mouse ear edema assay.
