QX77 is a chaperone-mediated autophagy (CMA) activator[1]. QX77 can activate CMA to ameliorate intracellular trafficking defects[2], and also reduce ferroptosis and alleviate oxidative stress[3-4].
In vitro, when human pancreatic stellate cells (HPSCs) treated with TGF-β1 were co-treated with QX77 (5ng/mL) and 20ng/mL MFG-E8 for 24 hours, QX77 eliminated the inhibitory effect of MFG-E8 on the TGF-β1-induced upregulation of LAMP2A expression and downregulation of MEF2D expression. QX77 attenuated the mitigating effect of MFG-E8 on oxidative stress[5]. In SKOV3/DDP cells treated with DDP (6μg/mL), intervention with QX77 (10μM) for 12 hours enhanced cell viability and affected the expression and localization of autophagy-related proteins[6].
In vivo, in a diabetic rat model, intravitreal injection of QX77 (2.5mg/kg) was administered once per week starting from the first day of model establishment for a duration of 2 weeks. QX77 significantly improved diabetes-induced impairment of retinal physiological function, reduced the expression of ACSL4 protein, decreased MDA levels and the accumulation of the toxic lipid peroxidation product 4-HNE in the retina, and reduced the number of autophagosomes, demonstrating a protective effect against early diabetic retinopathy[4].

| Cell experiment [1]: | |
Cell lines | Human pancreatic stellate cells (HPSCs) |
Preparation Method | HPSCs were cultured in Ham's F-12K medium supplemented with 20% fetal bovine serum (FBS) at 37°C, 5% CO₂. HPSCs were treated with TGF-β1 (5ng/mL) to induce activation, with or without QX77 (5ng/mL) and recombinant human MFG-E8 (20ng/mL) for 24 hours. |
Reaction Conditions | 5ng/mL; 24h |
Applications | QX77 upregulated LAMP2A expression and reversed the inhibitory effects of MFG-E8 on TGF-β1-induced CMA in HPSCs. QX77 also eliminated MFG-E8's suppressive effects on collagen I and α-SMA expression, as well as MFG-E8's reduction of oxidative stress in activated HPSCs. |
| Animal experiment [2]: | |
Animal models | Sprague-Dawley (SD) rats |
Preparation Method | Diabetic rats were established by streptozotocin (STZ) injection. QX77 (2.5mg/kg) was intravitreally injected on the first day of detectable hyperglycemia and maintained for 2 weeks. Animals were sacrificed for retinal analysis. |
Dosage form | 2.5mg/kg; i.p. |
Applications | QX77 significantly rescued retinal physiological function by reducing ACSL4 protein expression and lipid peroxidation (MDA and 4-HNE levels) in the RPE-Bruch's membrane-choriocapillaris complex. |
