Popis: | Under the aegis of the Pilot Scale Library Program of the NIH Roadmap Initiative, a new library of propan-1-amine containing aza acyclic nucleosides was designed and prepared, and we now report a diverse set of 157 purine, pyrimidine, and 1,2,4-triazole- N-acetamide analogues. These new nucleoside analogues were prepared in a parallel high throughput solution-phase format. A set of diverse amines was reacted with several nucleobase N-propaldehydes utilizing reductive amination with sodium triacetoxyborohydride coupling to produce a small and diverse aza acyclic nucleoside library. All reactions were performed using 24-well reaction blocks and an automatic reagent-dispensing platform under an inert atmosphere. Final targets were purified on an automated system using solid sample loading prepacked cartridges and prepacked silica gel columns. All compounds were characterized by NMR and HRMS and were analyzed for purity by HPLC prior to submission to the Molecular Libraries Small Molecule Repository (MLSMR). Initial screening through the Molecular Libraries Probe Production Centers Network (MLPCN) demonstrated diverse and interesting biological activities. |
