Synthesis of novel phytosphingosine derivatives and their preliminary biological evaluation for enhancing radiation therapy

Bioorg Med Chem Lett. 2007 Dec 1;17(23):6643-6. doi: 10.1016/j.bmcl.2007.09.037. Epub 2007 Sep 14.

Abstract

Eight d-ribo-phytosphingosine derivatives were synthesized from d-ribo-phytosphingosine and diverse acyl chlorides with N,N-diisopropylethylamine in tetrahydrofuran for 1h at room temperature. Effect of these compounds on IR-induced cell death was evaluated on blood cancer cells (Jurkat). Among these, 3d showed the highest enhancement of radiosensitizing effect.
