  Synthesis and antiviral activity of novel isonucleoside analogs

  摘要：

  A series of branched-chain sugar isonucleosides was synthesized and evaluated for antiviral activity against herpesviruses. The preparation of homochiral [3S-(3alpha,4beta,5alpha)]-2-amino-1,9-dihydro-9-[tetrahydro-4,5-bis(hydroxymethyl)-3-furanyl]-6H-purin-6-one (7, BMS-181,164) and related compounds was stereospecifically achieved starting from 1,2-isopropylidene-D-xylofuranose (10). An efficient two-step reduction of the anomeric center of bis-acetate 18 involved formation of the chloride intermediate 19, followed by diisobutylaluminum hydride reduction. Tosylation of the resulting alcohol 20 provided the key intermediate 21, which was coupled with a variety of nucleobase anions. Several members of this new class of compounds possess activity against herpes simplex virus types 1 and 2 (HSV-1 and -2), varicella-zoster virus (VZV), and human cytomegalovirus (HCMV). Compound 7 exhibits potent and selective activity against thymidine kinase encoding herpesviruses, in particular, HSV-1 and HSV-2. Evaluation of compound 7 for inhibition of WI-38 cell growth indicated an ID50 of > 700 muM. Although the antiherpetic activity in vitro of 7 is less than that of acyclovir (1), compound 7 displays superior efficacy in mouse model infections. The (bromovinyl)uridine analog 8 (BMS-181,165) also exhibits selective activity against HSV-1 and VZV, with no cytostatic effect on WI-38 cell growth at > 800 muM. Compound 8 is active against simian varicella virus and is efficacious in the corresponding monkey model.
