Kód oboru RIV: CC - Organická chemie
A series of novel 7-deazapurine ribonucleosides substituted with aryl and hetaryl groups has been prepared. Suzuki or Stille cross-coupling reactions with 6-chloro-7-deazapurine ribonucleosides substituted with H, F of Cl atom in position 7 were used in the key step of the synthesis. Either cross-coupling of protected ribonucleoside with appropriate (het)arylboronic acid or stannane followed by deprotection, or single-step aqueous-phase Suzuki cross-coupling reaction of unprotected 7-deazapurine ribonucleoside with boronic acid provided target (het)aryl-7-deazapurine ribonucleosides. 6-Furyl- and 6-thienyl-7-deazapurine ribonucleosides showed cytostatic effect in multiple cancer cell lines in nanomolar range. Application of cyclosaligenyl and alanyl-ester phosphoramidate prodrugs did not improved cytostatic activity of parent nucleosides.
