The synthesis of piperidine nucleoside analogs—a comparison of several methods to access the introduction of nucleobases
摘要:
This work deals with the synthesis of piperidine and hydroxypiperidine analogs of nucleosides. Starting from commercially available 3-hydroxypiperidine, proline or 4-hydroxyproline, a series of piperidine derivatives of both purine and pyrimidine nucleobases was prepared. Various methods of nucleobase attachment were evaluated. The prepared compounds were tested for cytostatic, antibacterial, and antiviral properties but no significant activity was found.

Compounds of formula (I) and salts thereof: (I) wherein R1 is hydrogen, methyl or –(CH2 )2 OR3, R2 is methyl or –(CH2)2 OR4, or R1 and R2, together with the nitrogen atom to which they are attached, are linked to form a 5-or 6- membered heterocyclyl wherein the 6-membered heterocyclyl is optionally substituted by two hydroxy substituents; R3 and R4 are each independently hydrogen or methyl; and n is an integer having a value of 5 or 6, are inducers of human interferon. Compounds which induce human interferon may be useful in the treatment or prevention of various disorders, for example the treatment or prevention of allergic diseases and other inflammatory conditions, for example allergic rhinitis and asthma, infectious diseases and cancer, and may also be useful as vaccine adjuvants.
Novel compounds termed lipophosphonoxins were prepared using a simple and efficient synthetic approach. The general structure of lipophosphonoxins consists of four modules: (i) a nucleoside module, (ii) an iminosugar module, (iii) a hydrophobic module (lipophilic alkyl chain), and (iv) a phosphonate linker module that holds together modules i-iii. Lipophosphonoxins displayed significant antibacterial properties against a panel of Gram-positive species, including multiresistant strains. The minimum inhibitory concentration (MIC) values of the best inhibitors were in the 1-12 mu g/mL range, while their cytotoxic concentrations against human cell lines were significantly above this range. The modular nature of this artificial scaffold offers a large number of possibilities for further modifications/exploitation of these compounds.
