Adenosine deaminase inhibitors. Synthesis and biological evaluation of C1' and nor-C1' derivatives of (+)-erythro-9-[2(S)-hydroxy-3(R)-nonyl]adenine
摘要:
The synthesis of various chiral derivatives of (+)-erythro-9-(2-hydroxy-3-nonyl)adenine, (+)-EHNA, from (2S,3R)-3-amino-1,2-O-isopropylidene-1,2-nonanediol by condensation with 5-amino-4,6-dichloropyrimidine is described. The compounds synthesized were Cl'- and nor-Cl'-(+)-EHNA derivatives. When tested with calf spleen ADA, Cl'-OH- and nor-Cl'-(+)-EHNA had comparable inhibitory activity that was 1 order of magnitude lower than that of (+)-EHNA. Potency was reduced further in nor-Cl' derivatives.

The synthesis of the title compound (15) and its 1'-fluoro (14) and 1'-hydroxy (12) derivatives is described. Key intermediate 10 was obtained by two routes through condensation of (2R,3R)-3-amino-1,2-O-isopropylidene-1,2-nonanediol (3) with either 2,4-dichloro- or 4-chloro-3-nitropyridine. When assayed as adenosine deaminase inhibitors, 15 was found to be almost twice as active as its racemate. While hydroxylation at the 1'-position resulted in an 80-fold decrease in activity, the 1'-fluoro derivative proved to have activity comparable to that of 3-deaza-(+)-EHNA.
