dc.description.abstract | The antiviral activities of carbocyclic adenosine analogues are well known and they have been shown to be due, or at least in part, to the inhibition of S-adenosylhomocysteine (SAH) hydrolase. Aristeromycin (the carbocylic analogue of adenosine) shows activity against vaccinia virus and inhibits SAH hydrolase with a Ki of 5 nM. Neplanocin A also inhibits vaccinia virus and has a Ki of 8 nM. Based on the potent inhibitory ancivites of racemic (±)-6--fluoroaristeromycin against SAH hydorolase, optically pure 6--fluoroaristeromycin and related analogues were synthesized from D-ribose using a Micheal reaction on the truncated cyclopentenone intermediate and electrophilic fluorination as key steps, because biological activity of the racemate generally resides of one enantiomer. ;Carbocyclic adenosine analogues의 antiviral activity는 잘 알려져 있고 이 acitivity는 S-adenosylhomocysteine(SAH) hydrolase를 저해하기 때문에 생긴 활성이다. aristeromycin과 neplanocin은 natural carbocyclic nucleoside로 vaccinia virus에 대해 활성을 보이고 SAH hydrolase를 저해하는 활성을 갖고 있다. 그러나 두 물질 모두 cytotoxicity가 강하기 때문에 임상적으로 쓰일 수 없어서, 적은 독성과 좋은 효능을 가진 SAH hydrolase 저해제를 개발하기 위해 많은 D-carbocyclic 유도체들이 설계, 합성 및 개발되어 왔다. 이전의 연구에서 6’-fluoroneplanocin이 neplanocin에 비해 독성이 적고 더 좋은 활성을 보인 것으로부터 착안하여 6’-fluoroaristeromycin을 합성하기로 하였다. 이미 개발이 된 (±)-6′-β-fluoroaristeromycin는 racemate지만 좋은 활성을 보였기 때문에 optically pure한 (-)-6′-β-fluoroaristeromycin와 그의 analogues를 합성하였다. 이 연구는 Michael reaction과 electrophilic fluorination을 이용한 (-)-D-6′-β-fluoroaristeromycin analogues의 성공적이고 asymmetric한 합성법과 biological activity에 대한 것이다. | - |
