The substraterecognition of Candida antarctica lipase B (CAL-B) in the acylation of nucleosides was revealed through rational substrate engineering for the first time. CAL-B displayed lower activities and excellent 5-regioselectivities (94 to 99 %) in the acylation of ribonucleosides 1f–1j as compared to those in the acylation of 2-deoxynucleosides 1a– 1e. The excellent regioselectivities might be

The substraterecognition of Pseudomonas cepacia lipase in the acylation of nucleosides was investigated by means of rational substrate engineering for the first time. P. cepacia lipase displayed excellent 3′-regioselectivities (96 to >99%) in the lauroylation of 2′-deoxynucleosides 1a–1e, while low to good 3′-regioselectivities (59–89%) in the lauroylation of ribonucleosides 1f–1j. It might be due

structures of the newly synthesised analogs were ascertained by analysing their physicochemical, elemental, and spectroscopic data. In vitro antimicrobial tests against five bacteria and two fungi, along with the prediction of activity spectra for substances (PASS), indicated promising antibacterial functionality for these thymidine analogs compared to antifungal activity. In support of this observation
