experiment example 1

[0148] Experimental example 1 Inhibition experiment of PI3K (p110α subtype)

[0149] The assay was performed with an enzyme (bovine p110α) produced by a baculovirus expression system. Enzymes were prepared according to "Cell (Cell)" by I Hile et al., 70, 419, 1992. Compounds to be evaluated were prepared as 10 mM (millimolar) DMSO solutions and serially diluted with DMSO.

[0150] Compounds (0.5 μl) and enzymes were evaluated in 25 μl buffer (40 mM Tris-HCl (pH 7.4), 200 mM NaCl, 2 mM dithiothreitol, 5 mM MgCl 2 ) after mixing, add 10 micrograms of PI (Sigma), 2µCi (microcurie) [γ- 32 P] ATP (Amersham Pharmacia), 80 μM (micromolar) non-radioactive ATP (Sigma) in 25 μl of 5 mM Tris-HCl (pH 7.4) buffer, the reaction was initiated. After reacting at 37°C for 15 minutes, add 200 μl of 1M HCl, 400 μl of CHCl 3 / MeOH (1:1), stirring, centrifugation. The organic layer was extracted two more times with 150 microliters of MeOH / 1M HCl (1:1), and its radioactivity was measured by C...

[0154] Experimental Example 2 Intestinal Cancer Cell Proliferation Inhibition Experiment

[0155] Intestinal cancer cell line HCT116 was cultured in McCoy's 5A medium (GIBCO) containing 10% fetal bovine serum. HCT116 (5000 cells / well) was inoculated on a 96-well plate and cultured overnight. Compounds diluted with culture medium were added thereto to a final concentration of 0.1-30 μM (final DMSO concentration, 1%). After culturing for 72 hours, Alamar Blue reagent was added. After 2 hours, the inhibitory activity IC was obtained from the fluorescence intensity ratio of the excitation wavelength of 530 nm and the emission wavelength of 590 nm 50 . of the present invention Co 14 , Co 24 , Co 25 , Co 31 , Co 46 with Co 47 The compound has a good inhibitory effect on cancer cell proliferation.

experiment example 3

[0156] Experimental Example 3 Proliferation Inhibition Experiment of Melanoma Cells

[0157] Melanoma cell line A375 cells were cultured in DMEM medium (GIBCO) containing 10% fetal bovine serum. A375 cells were pre-seeded at 10000 cells / 100 microliters on a 96-well plate containing 1 microliter per well (final concentration 0.001-30 microliters). After 46 hours of incubation, Alamar Blue reagent (10 μl / well) was added. After 2 hours, use the same method as above to determine the IC of the test compound from the fluorescence intensity ratio of the excitation wavelength of 530 nm and the emission wavelength of 590 nm 50 .

[0158] The compounds of the present invention have good growth inhibitory activity. E.g, Co 17 , Co 33 , Co 50 , Co 69 , Co 164 , Co 172 , Co 174 , Co 186 , Co 190 with Co 191 It has a good inhibitory effect on the proliferation of melanoma cells. its IC 50 Values ​​were 0.33-4.26 μM. The value of LY294002, which is a well-known ...

Abstract

Medicinal compositions which are useful as phosphatidylinositol 3-kinase (PI3K) inhibitors and anticancer agents; and novel bicyclic or tricyclic condensed heteroaryl derivatives or salts thereof having favorable effects of inhibiting PI3K and suppressing the proliferation of cancer cells.

Description

technical field [0001] The present invention relates to fused heteroaryl derivatives useful as pharmaceuticals, especially phosphatidylinositol 3-kinase (PI3K) inhibitors and anticancer agents. Background technique [0002] Phosphatidylinositol (hereinafter referred to as "PI") is one of cell membrane phospholipids, which is known to play a role in intracellular information transmission. In particular, it is well understood that PI(4,5) diphosphate (PI(4,5)P2) is broken down by phospholipase C into diacylglycerol and inositol (1,4,5) triphosphate, causing Activation of protein kinase C and intracellular calcium mobilization [MJ Berridge et al., Nature, 312, 315, (1984), Y Nishizuka, Science, 225, 1365 (1984)]. [0003] On the other hand, in the second half of the 1980s, PI3K was identified as an enzyme that phosphorylates the 3-position of the PI-inositol ring [D Whitman et al., Nature, 332, 664 (1988)]. [0004] PI3K was once thought to be a single enzyme when it was firs...
