Novel C-6 substituted pyrimidine derivatives are good substrates of herpes simplex virus type 1 thymidine kinase (HSV1-TK). Enzyme kinetic experiments showed that our lead compound, N-methyl DHBT (N-methyl-6-(1,3-dihydroxyisobutyl) thymine; N-Me DHBT), is phosphorylated at a similar rate compared to "gold standard" 9-[4-fluoro-3-(hydroxymethyl)butyl]guanine, FHBG, (K(m) = 10 +/- 0.3 muM; k(cat) = 0.036 +/- 0.015 sec(-1)). Additionally, it does not show cytotoxic properties on B16F1 cells up to a concentration of 10 mM. The x-ray analysis of the crystal structures of HSV1-TK with N-Me DHBT and of HSV1-TK with the fluorinated derivative N-Me FHBT confirmed the binding mode predicted by docking studies and their substrate characteristics. Moreover, the crystal structure of HSV1-TK with N-Me DHBT revealed an additional water-mediated H-bond interesting for the design of further analogues.

Molecular modeling and phosphorylation assay in vitro were employed to select a novel unsaturated 1,3-dihydroxyisobutenyl thymine derivative 6 as ligand for HSV-1 TK which may be of interest as lead for the development of an positron emission tomography (PET) imaging agent. Compound 6 was successfully prepared using modified approaches. A significant improvement over the syntheses involving pathways A and B (1% and 3% overall yield, respectively), was observed using synthetic route C (14% overall yield).
