Dalpiciclib (0-4 μM, 72 h) inhibits cell proliferation in a dose-dependent manner. Dalpiciclib (0-10 μM, 6 d) inhibits the proliferation of retinoblastoma-positive tumor cell lines. Cell Proliferation Assay Cell Line: Eca 109, Eca 9706, and KYSE-510 ESCC cell lines Concentration: 0-4 μM Incubation Time: 72 hours Result: Inhibited cell proliferation in a dose-dependent manner, with Eca 109 being the relative sensitive one and Eca 9706 being the relative resistant one. Cell Viability Assay Cell Line: MCF7, MCF7/TR, BT-474/T cell lines Concentration: 0-10 μM Incubation Time: 6 days Result: Inhibited MCF7/TR cells, parental MCF7 cells and BT-474/T resistant cells with the IC50 values of 229.5, 115.4 and 210.7 nM, respectively. |

Dalpiciclib (oral gavage; 150 mg/kg; once weekly; 3 weeks) shows antitumor activity against ESCC xenografts. Dalpiciclib combined with Paclitaxel (PTX) or Cisplatin (CDDP) offer synergistic inhibitory effects in ESCC xenografts. Dalpiciclib (oral gavage; 37.5 mg/kg, 75 mg/kg, 150 mg/kg; once daily; 30 days) shows antitumor activity in human xenograft models. Animal Model: NOD/SCID mice (ESCC PDXs models) Dosage: 150 mg/kg Administration: Oral gavage; 150 mg/kg; once weekly; 3 weeks Result: Suppressed the growth of tumor. Animal Model: 5-week-old female Balb/cA-nude mice subcutaneously inoculated MCF7/ARO, COLO 205 and U87MG Dosage: 37.5 mg/kg, 75 mg/kg, 150 mg/kg Administration: Oral gavage; 37.5 mg/kg, 75 mg/kg, 150 mg/kg; once daily; 30 days Result: Caused regression of all tumor xenografts at the highest dose tested. |
