IC50& Target | |
体外研究 (In Vitro) | Elimusertib potently inhibits the proliferation of a broad spectrum of human tumor cell lines with a median IC50of 78 nM[1]. Elimusertib potently suppresses hydroxyurea-induced H2AX phosphorylation (IC50: 36 nM)[1]. Elimusertib shows good selectivity against mTOR (ratio of IC50values: mTOR/ATR 61)[3]. Elimusertib reveals high selectivity against other related kinases, such as DNA-PK (IC50: 332 nM), ATM (IC50: 1420 nM), and PI3K (IC50: 3270 nM)[3]. Elimusertib has potent antiproliferative activity against various cancer cell lines in vitro, 25 for example in the CRC cell lines HT-29 (IC50: 160 nM) and LoVo (IC50: 71 nM), and in the B-cell lymphoma cell line SU-DHL-8 (IC50: 9 nM)[3].

体内研究 (In Vivo) | Elimusertib shows potent anti-tumor efficacy in monotherapy in a variety of xenograft models of ovarian and colorectal cancer, and causes complete tumor remission in mantle cell lymphoma models[2]. Elimusertib (50 mg/kg; p.o.; b.i.d.; 3 days on/4 days off; for 11 days) exhibits strong antitumor efficacy in the ATM-mutated SU-DHL-8 (ATM K1964E) human GCB-DLBCL cell line derived xenograft model in mice[3]. Elimusertib (20 mg/kg, and 10 mg/kg from day 14; p.o.; daily; 2 days on/5 days off; for 42 days) in combination with Carboplatin (40 mg/kg; i.p.; daily; 1 day on/6 days off) results in synergistic antitumor activity in the platinum-resistant ATM protein low expressing CR5038 human CRC PDX model in NOD/SCID mice[3]. Elimusertib exhibits moderate oral bioavailability (rat 87%, dog 51%) following oral administration (rat and dog 0.6-1 mg/kg)[3]. Elimusertib exhibits terminal elimination half-lives (mouse 0.17 h, rat 1.3 and, dog 1.0 h) due to plasma clearance (3.5, 1.2, and 0.79 L/h/kg respectively) following intravenous administration (mouse, rat and dog 0.3-0.5 mg/kg)[3].
Animal Model: | Female C.B-17 SCID mice, SU-DHL-8 GCB-DLBCL xenograft model[3] | Dosage: | 50 mg/kg | Administration: | Oral administration, b.i.d., 3 days on/4 days off, for 11 days | Result: | Inhibited tumor area. |
Animal Model: | Male Wistar rats[3] | Dosage: | 0.3-0.5 mg/kg for i.v.; 0.6-1 mg/kg for oral (Pharmacokinetic Analysis) | Administration: | Intravenous injection and oral administration | Result: | Oral bioavailability (87%), T1/2(1.3 h). |
Animal Model: | Female beagle dogs[3] | Dosage: | 0.3-0.5 mg/kg for i.v.; 0.6-1 mg/kg for oral (Pharmacokinetic Analysis) | Administration: | Intravenous injection and oral administration | Result: | Oral bioavailability (51%), T1/2(1.0 h). |
