Graphical Abstract

Sequence coins function: Sequences that bind m-THPC are selected from a library of thiolactone (Tla)/Michael oligomers by single-bead readout with MALDI-TOF MS/MS. The corresponding Tla/Michael-PEG conjugates make m-THPC available in solution and allow drug payload as well as drug release kinetics to be fine-tuned by sequence variation in the precision segment.

Abstract

Functional sequences of precision polymers based on thiolactone/Michael chemistry are identified from a large one-bead one-compound library. Single-bead readout by MALDI-TOF MS/MS identifies sequences that host m-THPC that is a second generation photo-sensitizer drug. The corresponding Tla/Michael-PEG conjugates make m-THPC available in solution and drug payload as well as drug release kinetics can be fine-tuned by the precision segment.
