DNA-encoded chemical libraries are increasingly being employed for the identification of binding molecules to protein targets of pharmaceutical relevance. Here, we describe the synthesis and characterization of a DNA-encoded chemical library, consisting of 4000 compounds generated by Diels-Alder cycloaddition reactions. The compounds were encoded with unique DNA fragments which were generated through

A simple and efficient one-pot three component synthesis of tetrahydropyrrolo[3′,4′:3,4]pyrrolo[2,1-a]isoquinoline-9,11-dione derivatives has been achieved from variously substituted isoquinolines, 2-bromo acetophenone and N-aryl maleimide derivatives in an aqueous micellar medium. The synthesis represents an environmentally benign alternative to classical methods.

A phase‐transfer catalytic 1,3‐dipolar [3+2] cycloaddition grants rapid generation of various trifluoromethyl spiro‐fused[succinimide‐pyrrolidine‐oxindole]s that might be of great utility for drug discovery. The gram‐scale reaction in conjunction with the derivatizations of the product demonstrate the synthetic potential of this methodology. The reaction mechanism is also discussed.
target for many diseases, however, up to now, there is no AC2-selective agonist reported. In this research, docking-based virtual screening with the combination of cell-based biological assays have been performed for discovering novel potent and selective AC2 agonists. Virtual screening disclosed a novel hit compound 8 as an AC2 agonist with EC50 value of 8.10 μM on recombinant human hAC2 + HEK293 cells
