First synthesis of enantiomerically pure carbocyclic oxanosine as a potential chemotherapeutic agent
摘要:
The first synthesis of optically active carbocyclic oxanosine 2 has been achieved in 14 steps from commercially available D-ribonic acid gamma-lactone. When evaluated for the inhibition activity of NGF-induced differentiation on PC12 cells, 2 was about 10-fold less active than natural oxanosine.
A series of sugar-modified derivatives of oxanosine and its carbocyclic analogs were synthesized from natural oxanosine and (−)-2-azabicyclo[2.2.1]hept-5-en-3-one, respectively. Among nucleosides tested for anti-HIV activities in vitro, oxanosine 1, its 5′-monophosphate 9, and 2′-deoxyoxanosine 8 reduced the number of HIV particles in CEM cells to almost the same level as ddI.
