Dihydro-Spiro[Indoline-3:1'-Isoquinolin]-2-Ones and Their Analogues and Derivatives and Methods of Treating Cancer and Other Diseases

The present invention is directed to various 3′,4′-dihydro-2′H-spiro[indoline-3:1′-isoquinolin]-2-one compounds and methods for treating disease states and/or conditions which are mediated through sphingosine-1-phosphate receptor(s). The present invention is also directed to the use of these compounds as anticancer agents and as modulators of sphingosine-1-phosphate receptor function in the treatment of disease states and/or conditions which are mediated through these receptors. In addition, the invention relates to pharmaceutical compositions comprising one or more of these compounds alone or in combination with other therapeutic agents. The invention is also directed to methods of treatment of cancer and/or conditions that may respond to the modulation of sphingosine-1-phosphate receptor function and which employ compounds of the present invention or pharmaceutical compositions comprising one or more of the compounds of this invention.
