One derivative of probucol is probucol disuccinate [1].
Probucol disuccinate exhibited antioxidant activity in vitro, with a DPPH free radical scavenging IC50 value of 23.6 μM [1] - In human hepatoma HepG2 cells, Probucol disuccinate inhibited intracellular lipid accumulation by 38% at a concentration of 50 μM, without significant cytotoxicity (cell viability > 85% at 100 μM) [1] - The compound showed inhibitory effects on LDL oxidation in vitro, reducing the formation of oxidized LDL by 45% at 20 μM after 24 hours of incubation [1] |
|---|---|
| ln Vivo |
In C57BL/6 mice fed a high-fat diet, oral administration of Probucol disuccinate at 50 mg/kg once daily for 4 weeks reduced serum total cholesterol by 32% and triglycerides by 27% compared to the model group [1]
- In apolipoprotein E knockout (ApoE-/-) mice, Probucol disuccinate (100 mg/kg, p.o., q.d. for 8 weeks) decreased aortic atherosclerotic plaque area by 41% and reduced serum oxidative stress markers (malondialdehyde) by 35% [1] |
| Enzyme Assay |
DPPH radical scavenging assay: A series of concentrations of Probucol disuccinate were mixed with DPPH solution (0.1 mM) in ethanol. The mixture was incubated in the dark at room temperature for 30 minutes, and the absorbance at 517 nm was measured. The IC50 value was calculated from the concentration-response curve of radical scavenging rate [1]
- LDL oxidation inhibition assay: Human LDL was incubated with CuSO4 (10 μM) to induce oxidation, and Probucol disuccinate was added at different concentrations. After incubation at 37°C for 24 hours, the content of oxidized LDL was determined by thiobarbituric acid reactive substances (TBARS) assay, and the inhibition rate was calculated [1] |
| Cell Assay |
HepG2 cell lipid accumulation assay: HepG2 cells were seeded in 6-well plates and cultured overnight, then treated with oleic acid (0.2 mM) to induce lipid accumulation. Probucol disuccinate was added at serial concentrations, and the cells were incubated for 24 hours. After fixation with formaldehyde, the cells were stained with Oil Red O, and the lipid content was quantified by measuring the absorbance at 510 nm after elution [1]
- Cell viability assay: HepG2 cells were seeded in 96-well plates and treated with Probucol disuccinate at concentrations ranging from 10 to 200 μM for 24 hours. MTT reagent was added and incubated for 4 hours, then the formazan crystals were dissolved, and the absorbance at 570 nm was measured to calculate cell viability [1] |
| Animal Protocol |
High-fat diet-induced hyperlipidemia mouse model: C57BL/6 mice (6-8 weeks old) were fed a high-fat diet for 2 weeks to establish the model. Mice were randomized into groups (n=10 per group), and Probucol disuccinate was formulated in 0.5% carboxymethylcellulose sodium solution and administered orally at 25 mg/kg, 50 mg/kg, or 100 mg/kg once daily for 4 weeks. Control group received vehicle. Serum lipid parameters (total cholesterol, triglycerides, LDL-C, HDL-C) were measured at the end of the study [1]
- Atherosclerotic mouse model: ApoE-/- mice (8 weeks old) were fed a high-cholesterol diet. Probucol disuccinate (100 mg/kg, p.o., q.d.) was administered for 8 weeks. At the end of the experiment, mice were sacrificed, and the aorta was isolated for atherosclerotic plaque staining and quantification. Serum oxidative stress markers and inflammatory factors were detected [1] |
| ADME/Pharmacokinetics |
Compared to the parent compound probucol (<0.1 mg/mL), probucol disuccinate has higher water solubility (12.8 mg/mL) [1]
- In a rat pharmacokinetic study, the oral bioavailability of probucol disuccinate (50 mg/kg) was 42%, which is 2.3 times that of probucol (18%) [1] - The plasma elimination half-life (t1/2) of probucol disuccinate in rats was 6.8 hours, and it was widely distributed in the liver, spleen and adipose tissue [1] |
| Toxicity/Toxicokinetics |
Acute toxicity studies in mice: Single oral administration of up to 2000 mg/kg of probucol succinate did not cause death or significant weight loss. Gross pathological examination of major organs showed no obvious abnormalities [1]
- Repeated-dose toxicity studies in rats (4 weeks, daily oral administration of 100, 300 or 600 mg/kg): No dose-related toxicity was found. Hematological, biochemical and histopathological parameters were all within the normal range [1] - The plasma protein binding rate of probucol succinate in human plasma was 86% as determined by balanced dialysis [1] |

| Additional Infomation |
Probucol disuccinate is a succinate derivative of probucol designed to improve the water solubility and oral bioavailability of the parent compound[1]. The compound exerts its pharmacological effects primarily through antioxidant activity and regulation of lipid metabolism, showing potential in the treatment of hyperlipidemia and atherosclerosis[1]. Compared to probucol, probucol disuccinate has better solubility and bioavailability, which may enhance its in vivo efficacy and reduce the frequency of administration[1].
