A549	2.5 ~ 60 µM		Blocked the PI3K/AKT signaling pathway, mediated mitochondrial apoptosis and inhibited autophagy	PMC11232884
MiaPaca-2	100 μM	72 h	Assess the cytotoxicity of CQ-HES, results showed similar cytotoxicity between CQ-HES and HCQ	PMC5996760
MiaPaca-1	100 μM	72 h	Assess the cytotoxicity of CQ-HES, results showed similar cytotoxicity between CQ-HES and HCQ	PMC5996760
Calu-3 cells	119 μM		To study the inhibitory effect of CQ and HCQ on SARS-CoV-2 infection, results showed that the effective dose in Calu-3 cells was significantly higher than in Vero E6 cells.	PMC7989365
Vero E6 cells	6.5 μM		To study the inhibitory effect of CQ and HCQ on SARS-CoV-2 infection, results showed that CQ and HCQ effectively inhibited viral invasion in Vero E6 cells.	PMC7989365

C57BL/6J mice	Nilotinib-induced nephrotoxicity model	Intragastric administration	30 mg/kg	Daily for 30 days	To investigate the intervention effect of chloroquine on nilotinib-induced nephrotoxicity. The results showed that chloroquine significantly ameliorated nilotinib-induced renal injury, reduced blood urea nitrogen and serum creatinine levels, and decreased renal fibrosis.	PMC10502815
Sprague Dawley (SD) rats	24-month-old rats	Oral	0.1 mg/kg	Twice a week for 5 months	Low-dose CQ treatment extended the lifespan of rats, repressed systemic inflammation, and inhibited fibrosis across multiple tissues. CQ treatment also reduced serum TNF-α levels and the numbers of circulating white blood cells and neutrophils, indicating attenuated chronic inflammation.	PMC9095792
Mice	C57Bl/6j mice	Intraperitoneal injection	50 mg/kg	Once daily for 10 days	Detected eIF2α phosphorylation levels, indicating that HCQ can induce eIF2α phosphorylation in vivo	PMC7790317
Mouse	Breast cancer model	Intraperitoneal injection	40 mg/kg	Once every two days	Inhibition of autophagy/mitophagy, induced apoptosis	PMC11232884
Mice	HCoV-OC43 infection model	Not specified	15 mg/kg	Not specified	To study the preventive effect of CQ on HCoV-OC43 infection, results showed that 15 mg/kg of CQ effectively prevented infection in mice.	PMC7989365
