Quinacrine (5-20 μM; 24 hours) inhibits the growth of SGC-7901 cells[1].
Quinacrine (7.5 and 15 μM; 24 hours) induces apoptosis in SGC-7901 cells, which is associated with mitochondria-dependent signal pathway and involves p53 upregulation and caspase-3 activation pathway[1].
Quinacrine (15 μM; 24 hours) treatment significantly increased the levels of proapoptotic proteins, including cytochrome c, Bax, and p53, and decreased the levels of antiapoptotic protein Bcl-2, thus shifting the ratio of Bax/Bcl-2 in favor of apoptosis [1].

-
Cell Line:SGC-7901 cells
-
Concentration:0, 5, 10, 15, and 20 μM
-
Incubation Time:24 hours
-
Result:Cell viability was inhibited in a dose-dependent manner, and the mean IC50 value is 16.18 μM.
-
Cell Line:SGC-7901 cells
-
Concentration:7.5 and 15 μM
-
Incubation Time:24 hours
-
Result:The percentage of apoptotic cells, including the early phase and late phase apoptosis, increased to 26.30%, compared with control group of 3.37%.
-
Cell Line:SGC-7901 cells
-
Concentration:15 μM
-
Incubation Time:24 hours
-
Result:The relative quantity of cytochrome c protein was upregulated, increased from 0.10 to 0.24.
The relative quantity of p53 protein was dramatically increased, from 0.06 to 0.19.
The Bax/Bcl-2 ratio was dramatically elevated from 1.21 to 2.59.

Animal Model:Female SCID mice with acute myeloid leukemia (AML)-PS model[2]
-
Dosage:100 mg/kg
-
Administration:Administered by oral gavage (po); three times a week for two consecutive weeks
-
Result:In the first AML mouse in vivo study, evaluation of circulating leukemic cells detected in blood samples (in percent of white blood cells (WBC)) at day 30/31 showed 72% human tumor cells in the control mice, whereas in mice treated with Quinacrine, this was only 2.2%.
The MST of control mice was 34 days whereas it was 46 days in Quinacrine-treated mice.

Cell viability of trophoblast cells treated with 10 μM Raptinal, 15 μM Quinacrine dihydrochloride, or 500 μg/mL PS-NPs, and co-treated with 10 μM Z-VAD-FMK for 48 h. The results showed that treatment with Raptinal, Quinacrine dihydrochloride, or PS-NPs reduced trophoblast cell viability, and co-treatment with Z-VAD-FMK rescued trophoblast cell viability.
