(+)-N6-Hydroxyagelasine D, the enantiomer of the proposed structure of (?)-ageloxime D, as well as N6-hydroxyagelasine analogs were synthesized by selective N-7 alkylation of N6-[tert-butyl(dimethyl)silyloxy]-9-methyl-9H-purin-6-amine in order to install the terpenoid side chain, followed by fluoride mediated removal of the TBDMS-protecting group. N6-Hydroxyagelasine D and the analog carrying a geranylgeranyl side chain displayed profound antimicrobial activities against several pathogenic bacteria and protozoa and inhibited bacterial biofilm formation. However these compounds were also toxic towards mammalian fibroblast cells (MRC-5). The spectral data of N6-hydroxyagelasine D did not match those reported for ageloxime D before. Hence, a revised structure of ageloxime D was proposed. Basic hydrolysis of agelasine D gave (+)-N-[4-amino-6-(methylamino)pyrimidin-5-yl]-N-copalylformamide, a compound with spectral data in full agreement with those reported for (?)-ageloxime D.

A series of 6-(ω-aroylthio)purines, which have not been described in the literature, has been obtained by the reaction of 6-purinethione with ω-chlorovalerophenone and its substituted derivatives. Some properties of the compounds synthesized have been studied, viz. reaction at the carbonyl group, methylation, and hydrolysis. 1999 KluwerAcademic/Plenum Publishers.

The reaction of 6-purinethione with α-haloketones has given a series of new 6-β-oxoalkyl(aralkyl, hetaralkyl, cycloalkyl)thiopurines.Their alkylation in position 9 and acid hydrolysis to hypoxanthine and its 9-alkyl derivatives has been studied.The hydrolysis of the acetals of 6-formylmethylthiopurine and the oxidation of 6-(2,3-dihydroxypropyl)thiopurine leads to 6-formylmethylthiopurine, which shows a ring-chain tautomerism and exists in the form of 7-hydroxy-7,8-dihydrothiazolopurine.
