title: Pyrrolo[3,4-c]quinoline-1,3-diones as potent caspase-3 inhibitors. Synthesis and SAR of 2-substituted 4-methyl-8-(morpholine-4-sulfonyl)-pyrrolo[3,4-c]quinoline-1,3-diones.
abstract: Synthesis, biological evaluation and structure-activity relationships for a series of 2-substituted 4-methyl-8-(morpholine-4-sulfonyl)-1,3-dioxo-2,3-dihydro-1H-pyrrolo[3,4-c]quinolines are described. These compounds represent a new chemotype of nonpeptide small molecule inhibitors of caspase-3. Among the studied compounds, several potent inhibitors with IC50 in the range of 3-10 nM have been identified. The most active compound within this series, 7{49} and 7{58}, inhibited caspase-3 with IC50=3 nM.
