  SYNTHESIS OF HALOGEN-SUBSTITUTED 3-DEAZAADENOSINE AND 3-DEAZAGUANOSINE ANALOGUES AS POTENTIAL ANTITUMOR/ANTIVIRAL AGENTS

  摘要：

  Various 2-halogen-substituted analogues (38, 39, 43 and 44), 3-halogen-substituted analogues (51 and 52), and 2',3'-dihalogen-substituted analogues (57-60) of 3-deazaadenosine and 3-halogen-substituted analogues (61 and 62) of 3-deazaguanosine have been synthesized as potential anticancer and/or antiviral agents. Among these compounds, 3-deaza-3-bromoguanosine (62) showed significant cytotoxicity against L1210, P388, CCRF-CEM and B16F10 cell lines in vitro, producing IC50 values of 3, 7, 9 and 7 muM, respectively. Several 3-deazaadenosine analogues (38, 51, 57 and 59) showed moderate to weak activity against hepatitis B virus.

  This paper describes the ready preparation of 3,6-difluoro-3-deazapurine (4,7-difluoroimidazo[4,5-c]pyridine). This novel base was glycosylated under mild conditions using three different ribose sugar analogs. 3,6-Difluoro-3-deazapurine ribonucleoside analogs underwent direct SNAr amination reactions with liquid ammonia to give 3-fluoro-3-deazaadenosine analogs in excellent yield; in contrast, 6-c

  A versatile synthetic route to 3-deaza-3-haloinosines 6-8 and 46, -adenosines 15-17 and 64, and -guanosines 25, 26, and 52 is described. 3-Deaza-3-chloro-, -bromo-, and -iodopurine ribonucleosides can be synthesized by treating the 3-deazapurine ribonucleosides with N-halosuccinimides. For the synthesis of 3-deaza-3-fluoropurine ribonucleosides, 5-formylimidazole-4-carboxamide ribosides 34 and 35 prepared from 5-iodoimidazole-4-carboxamide derivatives 29 and 31 were us ed as the key intermediates. The reaction of 34 and 35 with lithium (trimethylsilyl)acetylide and sodium cyanide, respectively, followed by appropriate manipulations gave 3-deaza-3-fluoroinosine derivative 46 and 3-deaza-3-fluoroguanosine derivative 52. 3-Deaza-3-fluoroadenosine (64) was also synthesized by selective reductive deamination of 4,6-diamino-7-fluoroimidazo[4,5-c]pyridine derivative 51, followed by deprotection. A conformational analysis using H-1 NMR and NOE experiments showed that the introduction of halogens (chloro, bromo, and iodo) into the 3-position of 3-deazapurine ribonucleosides forced fixation of the glycosyl torsion angle in the anti region, but did not-abnormally influence sugar puckering. On the other hand, 3-deaza-3-fluoropurine ribonucleosides should rotate freely around the glycosyl bond.
