- Mouse leukemia ⁇ 88 cells or human BCRP gene transfected P388 cells (P388 / BCRP cells, obtained from Yoshikazu Sugimoto, Cancer Chemotherapy Center, Cancer Society of Japan) suspended in 10% FBS / RPMI1640 in a 96-well microphone plate after seeding (1 X 10 4 cells / 50 l / wel 1), Jifue two Ruakurironi Bok Lil derivative and SN-38 to 103 ⁇ 4 FBS / RPNI16 40 were each dissolved 25 1 was added, 48 in 5% C0 2, 37 under Cultured for hours. After the culture, the number of viable cells was measured using Tetra Color ONE according to the attached operation procedure. Figure 6 shows the results.
- Human uterine cancer MES-SA cells or MES-SA / Dx5 cells with high expression of P-glycoprotein and acquired multidrug resistance [Cancer Res. 45, 4091-4096 (1985)] are suspended in 10% FBS / DMEM. Nigoshi, were cultured in 5% C0 2, 37 ° C conditions, it was seeded in 9 6-well microphone opening plate (3 X 10 3 cel ls / 50 xl / wel l). After overnight incubation, the 10% FBS / DMEM was dissolved diphenyl acrylonitrile derivatives and Pas Kuritakiseru added each 25 1, and cultured for 48 hours under 5% C0 2, 37 condition.
- EC 5 The ⁇ boss acting in Table 5 in multidrug resistance of each diphenyl ⁇ methacrylonitrile nitrile derivatives. Indicated by value. In addition, EC 5. The value is the concentration of the diphenylacrylonitrile derivative at which the relative resistance is reduced by 50%. As a result, the diphenylacrylonitrile derivative did not affect the paclitaxel resistance of MES-SA / DX5 cells in the concentration range studied. In addition, the diphenylacrylonitrile derivative itself did not affect the growth of MES-SA cells and 3 ⁇ 4ES-SA / Dx5 cells. The results indicated that the diphenylacrylonitrile derivative of the present invention did not act on P-glycoprotein and had specificity for BCRP.
- the cells were disrupted by adding 375 / l of PBS and sonication. To this cell lysate was added 375 of methanol and 15 xl of a 10% zinc sulfate solution, and the mixture was stirred and centrifuged (2 ° C, 12,500 xg, 5 min) to recover the supernatant. After dispensing the supernatant collected in a white 96-well microphone plate for fluorescence intensity measurement (200 ⁇ / well), the amount of SN-38 in the supernatant was measured using a microplate fluorometer (SN-38). : Excitation wavelength 380 nm, measurement wavelength 560 nm), and the amount of accumulation in cells was calculated.
- the diphenyl acrylonitrile derivative of the present invention increased the amount of P388 / BCRP cells accumulated in SN-38 cells.
- the diphenylacrylonitrile derivative of the present invention increased the amount of SN-38 accumulated in MCF-7 cells. This result suggests that the diphenylacrylonitrile derivative of the present invention inhibits BCRP and increases the amount of an anticancer agent taken into cells.
- Example 11 Effect of diphenylacrylonitrile derivative on in vivo resistance to anticancer drugs
- mice Six-week-old CDF, strain, female mice (5 / group) were inoculated with ⁇ 88 cells or P388 / BCRP (1 ⁇ 10 6 cel ls / mouse) intraperitoneally, and diphenylacrylonitrile derivative and irinotecan hydrochloride ( CPT-11) was intraperitoneally administered once a day for a total of 10 times from 1 day to 10 days after tumor implantation.
- the diphenyl acrylonitrile derivative is a physiological saline solution or ethanol, polyoxyethylene (20) sorbitan monooleate CTween 80 (trade name, manufactured by Tokyo Chemical Industry Co., Ltd.) and a 5% glucose mixture (ethanol I Tween).
- the BCRP inhibitory action of the diphenylacrylonitrile derivative of the present invention makes it possible to overcome BCRP-related resistance to anticancer drugs. It is also possible to enhance the effects of anticancer drugs against BCRP-expressing cancers. Furthermore, it is expected to improve the bioavailability of anti-acne drugs, which is expected to lead to improved treatment results in cancer chemotherapy.
