A novel series of pyrrolo[3,4-c] carbazoles fused with a quinolinyl/isoquinolinyl moiety were synthesized and their D1/CDK4 inhibitory and antiproliferative activity were evaluated. Compound 8H, 14H-isoquinolinyl[6,5-a]-pyrrolo[3,4-c]carbazole-7,9-dione (1d) was found to be a highly potent D1/CDK4 inhibitor with an IC50 of 69 nM. Compound Id also inhibited tumor cell growth, arrested tumor cells in G1 phase and inhibited pRb phosphorylation. (C) 2003 Elsevier Science Ltd. All rights reserved.
