  Enantiomeric Synthesis of d- and l-Cyclopentenyl Nucleosides and Their Antiviral Activity Against HIV and West Nile Virus

  摘要：

  Enantiomeric synthesis Of D- and L-cyclopentenyl nucleosides and their antiviral activity against HIV and West Nile virus are described. The key intermediate (-)- and (+)-cyclopentenyl alcohols (7 and 15) were prepared from D-gamma -ribonolactone and D-ribose, respectively. Coupling of 7 with appropriately blocked purine and pyrimidine bases via the Mitsunobu reaction followed by deprotection afforded the target L-(+)-cyclopentenyl nucleosides (24-28, 31, 33, and 36). D-(-)Cyclopentenyl nucleosides (1, 40, 43, and 52-56) were also prepared by a similar procedure for L-isomers from 15. The synthesized compounds were evaluated for their antiviral activity against two RNA viruses: HIV and West Nile virus. Among the synthesized D-(-)-nucleosides, adenine (1, neplanocin A), cytosine (55, CPE-C), and 5-fluorocytosine (56) analogues exhibited moderate to potent anti-HIV activity (EC50 0.1, 0.06, and 5.34 muM, respectively) with significant cytotoxicity in PBM, Vero, and CEM cells. Also, cytosine (55) and 5-fluorocytosine (56) analogues exhibited the most potent anti-West Nile virus activity (EC50 0.2-3.0 and 15-20 muM, respectively). Among L-(+)-nucleosides, only the cytosine (27) analogue exhibited weak anti-HIV activity (EC50 58.9 muM).

  Cyclopentenylcytosine (CPE-C, 2), a pyrimidine analogue of the fermentation derived carbocyclic nucleoside neplanocin A, has been synthesized from the optically active cyclopentenylamine 3b by two synthetic routes. CPE-C demonstrates significant antitumor activity against both the sensitive and ara-C resistant lines of L1210 leukemia in vivo. Multiple long term survivors are produced in both tumor

  环戊烯基胞嘧啶（CPE-C，2）是发酵衍生的碳环核苷内啡肽A的嘧啶类似物，它是通过光学合成的环戊烯基胺3b合成的。CPE-C在体内对L1210白血病的敏感株和ara-C耐药株均显示出显着的抗肿瘤活性。在两种肿瘤模型中均产生多个长期存活者。该化合物还对在无胸腺小鼠中生长的固体人A549肺和MX-1乳腺肿瘤异种移植物提供100％的生长抑制。还针对第三种人肿瘤异种移植模型转移性LOX黑色素瘤观察到良好的活性。CPE-C在体外对DNA和RNA病毒均具有显着活性。观察到针对HSV-1（TK +和TK-），HSV-2，牛痘，巨细胞病毒和水痘带状疱疹病毒的活性强。

  Compositions, devices, grafts and methods for reducing or preventing anti-neointima following cardiovascular injuries and interventions are disclosed. The compositions, devices, and grafts typically include an effective amount of a CTP synthase 1 inhibitor to reduce proliferation of vascular smooth muscle cells, without substantial reducing the proliferation of endothelial cells. Methods of reducing neointima formation, accelerating re-endothelialization, and reducing restenosis in a subject using the compositions, devices, and grafts are also disclosed.
