4、TIVITY物活性 MKT-077种花菁染料，也 种热休克蛋 70 (Hsp70) 抑制剂，且具有显着的抗肿瘤活性。IC50 & Target HSP70体外研究 MKT-077 is a rhodacyanine dye and also a heat shock protein 70 (Hsp70) inhibitor which exhibits significantantitumor activity. MKT-077 treatment (0.1 to 10 M dose ranges) for 48 hours can effectively decrease TTcell vi

5、ability. MKT-077 treatment results in accumulation of cells in the G0/G1 phase in a dose-dependentmanner, and also increases sub-G0/G1 phase population in TT cell culture in a dose-dependent manner.MKT-077 also downregulates cellular levels of the proliferation marker, Ki67, and the S-phase transcri

Moreover, flow cytometry using different doses of MKT-077reveales that TT cells can uptake and retain MKT-077 at significantly higher levels than MZ-CRC-1 cells 1.MKT-077 has EC50 values of 1.40.2 and 2.20.2 M against MDA-MB-231 and MCF7 breast cancer ce

7、lls,respectivelyl 2.体内研究 Systemic administration of MKT-077 significantly delays the growth of TT xenografts in mice throughout thetreatment. At the end of MKT-077 treatment, it is found that tumor weights are about two-times less in MKT-077-treated group than in control group. MKT-077 treatment als

Group 1 receives only the vehicle (1:9mixture of DMSO/saline) and group 2 receives MKT-077 (10 mg/kg body weight/dose). A 200 L of ethersolution is administered by intraperitoneal injec
