Abstract: Compounds of formula 1 are effective modulators of PI3 kinase: wherein R1 is H, hydroxy, amino, lower alkyl, or trihalomethyl; R2 is amino, lower alkylamino, lower acylamino, arylamino, arylacyl-amino, heteroaryl-amino, heteroaryl-acyl amino, where aryl and heteroaryl are substituted with 0-3 substituents selected from the group consisting of halo, trihalomethyl, hydroxy, lower alkyl and lower alkoxy, or a substituent of the form —(CH2)n—C(?X)—R8, where n is 014 3 inclusive and X is O or NR9, where R9 is H, lower alkyl, or R1 and R2 together form —CH?N—X— where X is CH, NH, O, or S, and R8 is H, lower alkyl, lower alkoxy, aryl, aralkyl, or —(CH2)mCR10R11R12, where m is 0-3 inclusive, and R10, R11, and R12 are each independently H, lower alkyl, aryl, aralkyl, hydroxy, lower alkoxy, aryloxy, aralkoxy, amino, lower alkyl-amino, arylamino, aralkylamino, heteroaryl amino, or heteroaralkyl amino, where aryl and heteroaryl are substituted with 0-3 substituents selected from the group consisting of halo, hydrox

Abstract: Compounds of formula 1 are effective modulators of PI3 kinase: wherein X is CR9R10, O, NR11 (where R9 and R10 are each independently H, lower alkyl, lower alkoxy, or halo, and R11 is H or lower alkyl); or single bond; R1 is H, lower alkyl, aryl, aralkyl; R2 is H, lower alkyl, aryl, aralkyl, heteroaryl, heteroaryl-alkyl, lower alkoxy, amino, lower alkylamino, lower acylamino, arylamino, arylacyl-amino, heteroaryl-amino, heteroaryl-acyl amino, thio, lower alkylthio, arylthio, or aralkyl-thio, where aryl and heteroaryl are substituted with 0-3 substituents selected from the group consisting of halo, trihalomethyl, hydroxy, lower alkyl and lower alkoxy; R3, R4, R5, R6, R7, and R8 are each independently H, lower alkyl, lower alkoxy, or halo; or a pharmaceutically acceptable salt or ester thereof.
