  Synthesis of deuterated-BCX-34 (peldesine)

  摘要：

  BCX-34 (peldesine) is a novel purine nucleoside phosphorylase inhibitor that is in human clinical trials for the treatment of T-cell cancers and for: HIV infected patients. In support of our BCX-34 clinical program, a mass spectrometric assay has been developed utilizing a deuterated-BCX-34 analog as an internal standard. The synthesis of tetra-deuterated-BCX-34 (peldesine) from ethyl nicotinate. (2,4,5,6-[H-2](4)) is,described in this report.

  produce pyridyloxobutyl (POB)-DNA adducts. POB-DNA adduct formation plays a critical role in NNN and NNK carcinogenicity in rodents. To further investigate the significance of this pathway, we developed a high-performance liquid chromatography-electrospray ionization-tandem mass spectrometry (HPLC-ESI-MS/MS) method for quantitative analysis of four POB-DNA adducts with known structures. The corresponding

The synthetic strategy reported here is similar to that reported in the literature for the preparation of corresponding unlabeled compounds. The commercially available [2,4,5,6-d4]ethylnicotinate was used as starting material. During the course of these syntheses [2,4,5,6-d4]myosmine and [2,4,5,6-d4]nornicotine were

  N-Nitrosamines of tobacco alkaloids contribute to the cause of tobacco related cancers and, therefore, they are important analytes. Herein the preparation of four partially deuterated N-nitrosamines from simple, commercially available, deuterated educts is described, which can serve as useful standards in tobacco-smoke analysis.
