Stereoselective synthesis of 3,4‐dihydropyrrolo[1,2‐a]pyrazin‐1(2H)‐one derivatives as PIM kinase inhibitors inspired from marine alkaloids

Abstract: We previously demonstrated that natural product‐inspired 3,4‐dihydropyrrolo[1,2‐a]pyrazin‐1(2H)‐ones derivatives delivered potent and selective PIM kinases inhibitors however with non‐optimal ADME/PK properties and modest oral bioavailability. Herein, we describe a structure‐based scaffold decoration and a stereoselective approach to this chemical class. The synthesis, structure–activity relationship studies, chiral analysis, and pharmacokinetic data of compounds from this inhibitor class are presented herein.… Show more

“…Although the bioavailability has improved, it may come at the cost of sacrificing some of the inhibitory potency against PIM enzymes (Figure 12A). 139 Furthermore, 112 (Usnic acid) is a metabolite extracted from lichen that possesses distinct anticancer properties due to its distinctive dibenzofuran scaffold. In order to enhance its therapeutic potential, flavonoids were incorporated into the structure of 112, which led to the synthesis of 113.…”

“…In 2022, Casuscelli et al described a structure-based scaffold decoration and a stereoselective approach to discover new PIM kinases inhibitors. The synthesis, structure-activity relationship studies, chiral analysis, and pharmacokinetic data of 3,4dihydropyrrolo[1,2-a]pyrazin-1(2H)-one derivatives revealed that compound ( 34) is an excellent Pim1 and Pim2 inhibitor (Casuscelli et al 2022).…”
