title: Antitumor agents 187: synthesis and cytotoxicity of substituted 8,8-dimethyl-2H,8H-pyrano[6,5-h]quinoline-2-one and related compounds.
abstract: Several substituted 8,8-dimethyl-2H,8H-pyrano[6,5-h]quinoline-2-ones and related compounds were synthesized and evaluated for their in vitro cytotoxicity against a panel of human tumor cell lines. The most active compound (3) showed significant cytotoxic activity with GI50 values in the micromolar range.
