  • Publication number: 20140135499
    Abstract: The present invention discloses and claims five (5) novel, highly efficient synthetic routes for the total synthesis of enantiomerically-pure (i.e., 99%) 7-(2?-trimethylsilyl)ethyl camptothecin (BNP1350; Karenitecin; Cositecan). These aforementioned synthetic schemes are the first to disclose the total syntheses of 7-(2?-trimethylsilyl)ethyl camptothecin using a highly novel direct, non-linear and convergent synthetic strategy which involves annealing the key C7-(trimethylsilyl)ethyl side chain-bearing A ring key synthons to an enantiomerically-pure tricyclic pyridone; rather than through the conventional methodology which incorporates the C7-(trimethylsilyl)ethyl side chain as the final synthetic step on a totally synthesized camptothecin parent compound.

  • Patent number: 7759488
    Abstract: Disclosed herein are novel platinum-based analogs with a single substituted azole ligand: RN?NR7, wherein the RN?NR7 functional group is covalently bonded to the platinum through nitrogen of NR7. The analogs also have nitrogen donor ligands capable of forming hydrogen bonds with the bases in DNA or RNA, and one or more leaving groups which can be displaced by water, hydroxide ions or other nucleophiles, which is thought to form active species in vivo, and then, form cross-linked complexes between nucleic acid strands, principally between purines in DNA (or RNA), i.e., at the Guanine or Adenine bases, thereof.
