Abstract
The reaction between 1-aminosugars and trimethylisocyanate (TMSNCO) was optimised as a one-step synthetic strategy for the synthesis of sugar biurets. This protocol was successfully applied to a number of 1-aminosugars, which exclusively provided the corresponding biurets in 67-99% yields. The new methodology was applied in the de novo synthesis of N1-(2-deoxy-α/β-d-erythro-pentofuranosyl)biuret (dfBU) and N1-(2-deoxy-α/β-d-erythro-pentopyranosyl)biuret (dpBU), two known DNA lesions arising from the hydroxyl radical induced decomposition of 2'-deoxycytidine (dCyd).

Synthesis and in vitro growth inhibitory activity of novel silyl- and trityl-modified nucleosides. Bioorg Med Chem 2016; 24:2716-24. [PMID: 27157005 DOI: 10.1016/j.bmc.2016.04.036] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2016] [Revised: 04/14/2016] [Accepted: 04/19/2016] [Indexed: 12/17/2022]
Abstract
Seventeen silyl- and trityl-modified (5'-O- and 3',5'-di-O-) nucleosides were synthesized with the aim of investigating the in vitro antiproliferative activities of these nucleoside derivatives. A subset of the compounds was evaluated at a fixed concentration of 100μM against a small panel of tumor cell lines (HL-60, K-562, Jurkat, Caco-2 and HT-29). The entire set was also tested at varying concentrations against two human glioma lines (U373 and Hs683) to obtain GI50 values, with the best results being values of ∼25μM.
