The present application relates to novel C-1 substituted analogues of pancratistatin and 7-dexoypancratistatin of Formula (I), pharmaceutical compositions thereof and the use of said compounds of Formula (I) in the treatment of cancer The application also relates to processes for the preparation of said compound of Formula (I) and intermediates thereof.
Total Synthesis of 7-Deoxypancratistatin-1-carboxaldehyde and Carboxylic Acid via Solvent-Free Intramolecular Aziridine Opening: Phenanthrene to Phenanthridone Cyclization Strategy
Solid-state silica-gel-catalyzed opening of aziridine 6 provided phenanthrene 7, whose oxidative cleavage, recyclization, and further elaboration furnished the C-1 aldehyde and carboxylic acid derivatives of 7-deoxypancratistatin for potential analogue synthesis.
Chemoenzymatic Synthesis of Amaryllidaceae Constituents and Biological Evaluation of their C-1 Analogues. The Next Generation Synthesis of 7-Deoxypancratistatin and <i>trans</i>-Dihydrolycoricidine
this aldehyde to C-1 acetoxymethyl and C-1 hydroxymethyl derivatives is described along with the evaluation of their biological activity against several cancer cell lines and in an apoptosis study. The C-1 acetoxymethyl derivative has shown promising activity comparable to that of the natural product. In addition, a totalsynthesis of trans-dihydrolycoricidine and a formal totalsynthesis of 7-deoxypancratistatin
