: CX-5461 dihydrochloride purchased from MedChemExpress. Usage Cited in: Clin Cancer Res. 2017 Nov 1;23(21):6529-6540. [Abstract]; Western blot analysis verifying G2/M phase arrest in 6 cell lines. Treatment with IC₅₀ dosages of CX-5461 shows an increase in expression of pCDC2(tyr15) and Cyclin-B versus untreated controls at 72 hours.

: CX-5461 dihydrochloride purchased from MedChemExpress. Usage Cited in: Clin Cancer Res. 2017 Nov 1;23(21):6529-6540. [Abstract]; Western blot analysis shows activation of the pCHK1(ser317) and pCHK2(T68), downstream substrates of ATM and ATR kinases. TP53 wild type cell lines show a subsequent activation of p21 but drug response is independent of TP53 status.

IC₅₀ & Target

体外実験

CX-5461 is a potent and orally bioavailable inhibitor of Pol I-mediated rRNA synthesis, with IC₅₀s of 142 nM in HCT-116, 113 nM in A375, and 54 nM in MIA PaCa-2 cells, and shows little or no effect on Pol II (IC₅₀, ≥25 μM). CX-5461 has modest inhibition on DNA replication and protein translation. CX-5461 also exhibits broad antiproliferative activity against a panel of human cancer cell lines, with a mean EC₅₀ of 147 nM, but has minimal effect on viability of nontransformed human cells, with EC₅₀ values of appr 5000 nM. EC₅₀s of CX-5461 for HCT-116, A375, and MIA PaCa-2 cell lines are 167, 58, and 74 nM, respectively. CX-5461 induces autophagy and senescence in solid tumor cancer cells, rather than apoptosis, through a p53-independent process^[1]. Eμ-Myc lymphoma cells from tumor-bearing mice are exquisitely sensitive to CX-5461 with an IC₅₀ of 27.3 nM ± 8.1 nM for Pol I transcription after 1 hr and IC₅₀ of 5.4 nM ± 2.1 nM for cell death after 16 hr. CX-5461 activates p53 via the nucleolar stress response in Eμ-MycLymphoma Cells^[2].

体内実験

CX-5461 displays antitumor activity against human solid tumors in murine xenograft models. CX-5461 (50 mg/kg, p.o.) shows significant MIA PaCa-2 growth inhibition with TGI equal to 69% on day 31 and 79% TGI on A375 on day 32^[1]. CX-5461 (50 mg/kg, p.o.) inhibits the Eμ-Myc tumor cells with 84% repression in Pol I transcription at 1 hr posttreatment in C57BL/6 mice. CX-5461 also induces a rapid reduction in tumor burden in the lymph nodes and a concomitant reduction of spleen size to within the normal range^[2].

細胞実験 ^[1]	Cells are plated on 96-well plates and treated the next day with dose response of CX-5461 for 96 hours. Cell viability is determined using Alamar Blue and CyQUANT assays^[1]. MedChemExpress (MCE) はこれらの方法の精度を確認していません。こちらは参照専用です。
動物実験 ^[1]	Mice^[1] Animal experiments are performed with 5- to 6-week-old female athymic (NCr nu/nu fisol) mice of Balb/c. Mice are inoculated with athymic (NCr nu/nu fisol) mice in 100 μL of cell suspension subcutaneously in the right flank. Tumor measurements are performed by caliper analysis, and tumor volume is calculated using the formula (l×w²)/2, where w=width and l=length in mm of the tumor. established tumors (appr 110-120 mm³) are randomized into vehicle (50 mM NaH₂PO₄, pH 4.5), NSC 613327, or CX-5461 treatment groups. Tumor growth inhibition (TGI) is determined on the last day of study according to the formula: TGI (%)=[100 − (Vf^D− Vi^D)/ (Vf^V − Vi^V) × 100], where Vi^V is the initial mean tumor volume in vehicle-treated group, Vf^V is the final mean tumor volume in vehicle-treated group, Vi^D is the initial mean tumor volume in drug-treated group, and Vf^D is the final mean tumor volume in drug-treated group.
