產(chǎn)品名稱：Olaparib 產(chǎn)品貨號(hào)：LC O-9201 產(chǎn)品規(guī)格：100 MG Olaparib is a poly(ADP-ribose) polymerase 1 (PARP1) inhibitor and an anti-cancer drug being tested in patients with mutations in the genes BRCA1 or BRCA2. PARP1 acts as a critical molecule in the repair of DNA single-strand breaks (SSBs) and plays an important role in maintaining DNA integrity. de Murcia, J., et al. "Requirement of poly(ADP-ribose) polymerase in recovery from DNA damage in mice and in cells." Proc. Natl. Acad. Sci. USA 94: 7303-7307 (1997). PARP inhibitors inhibit PARP1 during S-phase and induce inactivation of SSB repair and thus cause DNA double-strand breaks, which induces BRCA-deficient cancer cell apoptosis. Bryant, H.E., et al. "Specific killing of BRCA2-deficient tumours with inhibitors of poly(ADP-ribose) polymerase." Nature 434: 913-917 (2005). Farmer, H., et al. "Targeting the DNA repair defect in BRCA mutant cells as a therapeutic strategy." Nature 434: 917-921 (2005). The PARP inhibitor olaparib was tested in a genetically engineered mouse model for BRCA1-associated breast cancer. Olaparib inhibited tumor growth and significantly improved survival without signs of toxicity. Rottenberg, S., et al. "High sensitivity of BRCA1-deficient mammary tumors to the PARP inhibitor AZD2281 alone and in combination with platinum drugs." Proc. Natl. Acad. Sci. USA 105: 17079-17084 (2008). Long-term treatment with olaparib caused the development of drug resistance, which was induced by up-regulation of Abcb1a/b genes encoding P-glycoprotein efflux pumps. The resistance to olaparib could be overcome by tariquidar, a P-glycoprotein inhibitor. Rottenberg, S., et al. "High sensitivity of BRCA1-deficient mammary tumors to the PARP inhibitor AZD2281 alone and in combination with platinum drugs." Proc. Natl. Acad. Sci. USA 105: 17079-17084 (2008). Combination treatment using olaparib with cisplatin or carboplatin improved the recurrence-free and overall survival in a murine model, indicating that olaparib enhances the effect of these DNA-damaging agents. Rottenberg, S., et al. "High sensitivity of BRCA1-deficient mammary tumors to the PARP inhibitor AZD2281 alone and in combination with platinum drugs." Proc. Natl. Acad. Sci. USA 105: 17079-17084 (2008). Olaparib inhibited the growth of BRCA2-deficient versus BRCA2-proficient mammary tumor cells. Combination treatment of olaparib and cisplatin had a synergistic cytotoxicity against BRCA2-deficient cells but not against BRCA2-proficient control cells. Evers, B., et al. "Selective inhibition of BRCA2-deficient mammary tumor cell growth by AZD2281 and cisplatin." Clin. Cancer Res. 14: 3916-3925 (2008). Other CAS numbers previously assigned to olaparib, namely 894104-70-2, 937799-91-2, and 1021843-02-6, have been deleted by CAS and are no longer in use. Storage: Store at or below -20 ºC. Solubility: Soluble in DMSO at 33 mg/mL; soluble in ethanol at 1.7 mg/mL with slight warming; very poorly soluble in water; maximum solubility in plain water is estimated to be about 10-20 µM buffers, serum, or other additives may increase or decrease the aqueous solubility.
