Some novel pyrazole acyclonucleosides were prepared through binding of pyrazole-3,5-substituted derivatives with acyclic substituents mimetizing individual fragments of the ribose ring such as: 1-[(2-hydroxyethoxy) methyl], 1-[4-(hydroxybutyl)], 1-[3- (hydroxypropyl)] and 1-[(2-hydroxyethyl amino) methyl]. Their syntheses were performed from easily accessible starting materials. The prepared compounds were evaluated for their antibacterial activity. Structure-activity relationship studies (SAR) indicate that introduction of modified arm in N1 position of pyrazole moieties has not any impact on the biolgical activity.
