Sapacitabine

SKU: orb1679012

Description

Sapacitabine (CS-682) is an orally bioavailable nucleoside analog prodrug investigated for acute myeloid leukemia (AML). Preclinical in vitro and in vivo studies demonstrate its anti-tumor activity via DNA synthesis inhibition, supporting its role as a research compound for oncology and hematology.

Bioactivity

• In Vivo:
  On day 14, the average tumor volume in the sapacitabine (5 mg/kg) + vorinostat (33 mg/kg) group was 245 mm3, and the tumor growth inhibition (TGI) was 92%, while the sapacitabine (15 mg) group /kg) group, the average tumor volume was 245mm3, and the tumor growth inhibition (TGI) was 92%; the +vorinostat (33 mg/kg) group had an average tumor volume of 107mm3, and the TGI was 112% .

• In Vitro:
  The IC50 values of sapacitabine concentrations against colon cancer cell line HCT116 and breast cancer cell line MDA-MB-435 were 3 ± 0.6 µM and 67 ± 14 µM. Cell cycle analysis showed that 35% of the cells treated with sapacitabine were arrested in the late S phase and 41% were arrested in the G2/M phase. Sapacitabine is sensitive (IC50 20±6 μM) to L1210 cells with deoxycytidine kinase (dCK) activity .

• Cell Research:
  A panel of the colon (HT29, HCT116, COLO205, HCC2998), breast (MCF7, MDA-MB-435), lung (HOP62, HOP92), ovarian (OVCAR3, IGROV1) cancer cell lines are used in this study. The cell cycle stage and percentage of apoptotic cells are assessed by flow cytometry. In brief, cells are seeded in 25 cm3 flasks and are untreated or treated with various concentrations of Sapacitabine. At the indicated time points, adherent and non-adherent cells are collected, washed with PBS, fixed in 70% ethanol and stored at 4°C until use. Cells are rehydrated in PBS, incubated for 20 min at room temperature (25°C) with 250 μg/mL RNAse A with Triton X-100 and 20 min at 4°C with 50 μg/mL propidium iodide in the dark. The cell cycle distribution and percentage of apoptotic cells are determined with a flow cytometer and analysed by FACS Calibur .

• Animal Research:
  Female (nu/nu) mice are injected subcutaneously with 1×107 MV4-11 cells resuspended in 50% Matrigel at a single site on their flanks. Once tumour volumes are 126 to 256 mm3 (16 days post-implantation) animals are pair-matched by tumour size into treatment groups (minimum of six mice per group) with a mean tumour size of ~190 mm3. Tumour measurements are calculated using the formula: volume (mm3)=width2 (mm)×length (mm)×0.5. Sapacitabine is administered once a day orally (5 or 15 mg/kg) for 4 days, followed by a 3-day break before another 4 days of treatment; dosing starts on the same day as distribution to the treatment groups .
