( diluted with the assay buffer to 0 . 25 nm ) was added to the plate at 20 μl per well , and the resulting mixture was stirred . a reaction was performed at 30 ° c . for one hour . after the plate was washed 4 times with a washing buffer ( 50 mm tris - cl ( ph 7 . 5 ), 150 mm nacl , and 0 . 02 ( v / v ) % tween - 20 ), a blocking buffer ( 0 . 1 % bovine serum albumin , 50 mm tris - cl ( ph 7 . 5 ), 150 mm nacl , and 0 . 02 ( v / v ) % tween - 20 ) was added to the plate at 150 μl per well , and incubated at 30 ° c . for 30 minutes . the blocking buffer was then removed , and a horse radish peroxidase - labeled anti - phosphorylated tyrosine antibody ( bd biosciences , inc .) ( diluted with the blocking buffer to 10 , 000 - fold ) was added to the plate at 100 μl per well , and the plate was incubated at 30 ° c . for 30 minutes . after the plate was washed 4 times with the washing buffer , a 3 , 3 ′, 5 , 5 ′- tetramethylbenzidine solution ( sigma - aldrich co ., ltd .) was added to the plate at 100 μl per well to develop the color for 10 minutes . the reaction was stopped by adding 0 . 1 m sulfuric acid at 100 μl per well . an absorbance at 450 nm was measured with a microplate reader ( model 3550 , manufactured by bio - rad , benchmark , manufactured by bio - rad , or imark , manufactured by bio - rad ). a non - linear regression analysis was performed for the measured absorbance with an sas system ( sas institute inc . ), and a concentration of each of the test substances of inhibiting the ros tyrosine kinase activity or jak2 tyrosine kinase activity at 50 % ( ic 50 ) was calculated . the inhibitory activity ( ic 50 , nm ) of each of the test substances against the ros tyrosine kinase or jak2 tyrosine kinase is shown in tables 6 to 8 . a baf3 cell which had been transformed by introducing the fig - ros fusion gene ( derived from u118mg human glioma cell ) ( fig - ros / baf3 cell ) was prepared on a culture medium , seeded on a 96 - well plate in the number of 1 × 10 3 / 100 μl per well , and then allowed to stand in a co 2 incubator ( at 37 ° c . and 5 % co 2 ). as the culture medium , 10 % fbs ( fetal bovine serum )- incorporated rpmi - 1640 was used . a test substance was dissolved in dimethyl sulfoxide ( dmso ) to 10 mm and further diluted with dmso to 100 - fold to prepare a 100 μm solution . this was diluted with a 1 % dmso - incorporated medium to concentrations of 10 - fold of the concentration to be measured ( 10 , 000 , 1 , 000 , 100 , 10 , and 1 nm ). each of the medicine solutions was added at 11 μl per well and mixed . to a control having no medicine added thereto , a 1 % dmso - incorporated medium was added , and incubated in a co 2 incubator ( at 37 ° c . and 5 % co 2 ) for 3 days . after completion of the incubation , the number of live cells was counted using a cell counting kit . first of all , each cell counting kit solution was added at 5 μl per well and mixed , and incubated in a co 2 incubator ( at 37 ° c . and 5 % co 2 ) for 4 hours . an absorbance at 450 nm was measured with a microplate reader ( model 3550 , manufactured by bio - rad , benchmark , manufactured by bio - rad , or imark , manufactured by bio - rad ) with a reference wavelength of 650 nm . a non - linear regression analysis was performed for the measured absorbance with an sas system ( sas institute inc . ), and a concentration of each of the test substances of inhibiting the cell proliferation at 50 % ( ic 50 ) was calculated . the proliferation inhibitory activity ( ic 50 , nm ) of each of the test substances against the fig - ros / baf3 cell is shown in table 9 . as described above , the compound of the present invention or its pharmaceutically acceptable salt has high ros tyrosine kinase inhibitory activity and can be used as a preventing agent or a treating agent for especially glioma , non - small cell lung cancer , angiosarcoma , inflammatory myofibroblastic tumor , ovarian cancer , gastric cancer , ovarian cancer , epithelioid hemangioendothelioma , colorectal cancer , liposarcoma , or spitzoid neoplasms .
