Hydroxypropyl-beta-cyclodextrin is an ether derivative generated by the reaction of beta-Cyclodextrin with epichlorohydrin[1]. Hydroxypropyl-beta-cyclodextrin can form water-soluble complexes by encapsulating poorly soluble drug molecules in hydrophobic cavity, significantly enhancing the solubility and bioavailability of the drugs. Hydroxypropyl-beta-cyclodextrin can also be used as a pharmaceutical excipient in oral, injectable, and mucosal drug delivery systems[2]. Hydroxypropyl-beta-cyclodextrin can bind and dissolve cholesterol crystals within cells, promote cholesterol efflux and metabolism, and enhance lysosomal function and autophagic clearance by activating transcription factor EB[3]. Hydroxypropyl-beta-cyclodextrin can disrupt cholesterol homeostasis, inducing G2/M cell cycle arrest and apoptosis in leukemia cells, and systemic administration has been shown to be safe[4].
In vitro, after pre-treatment of bone marrow-derived macrophages (BMDMs) with Hydroxypropyl-beta-cyclodextrin (1.95mM) for 4 hours, followed by stimulation with lipopolysaccharide (LPS; 100ng/ml) for 4 hours, Hydroxypropyl-beta-cyclodextrin significantly increased the protein secretion of the pro-inflammatory cytokine TNF-α, upregulated the expression of pro-inflammatory genes, and downregulated the expression of anti-inflammatory genes[5]. Hydroxypropyl-beta-cyclodextrin (2.5–20mM) pre-treatment of Vero E6 cells and Calu-3 lung epithelial cells for 1 hour, followed by infection with SARS-CoV-2 (MOI = 0.1–0.5) for 24–72 hours, significantly inhibited viral replication and reduced virus-induced inflammation[6].
In vivo, Hydroxypropyl-beta-cyclodextrin (4000mg/kg; intraperitoneal injection twice a week) was used to treat Tg19959 Alzheimer's disease model mice for 4 months. Hydroxypropyl-beta-cyclodextrin significantly improved the learning and memory functions of the mice, reduced amyloid-beta (Aβ) plaque deposition, and attenuated tau pathology in the brain[7]. Hydroxypropyl-beta-cyclodextrin (10% w/v) was used as a drug carrier and administered intravenously three times a week (at a dose of 2.5–20mg/kg) to NOD/SCID mice that had been inoculated with SU-DHL-6 tumor cells. Hydroxypropyl-beta-cyclodextrin significantly increased the water solubility of Purinostat Mesylate (PM), enhanced its anti-tumor efficacy, and improved its pharmacokinetic properties[8].

| Cell experiment [1]: | |
Cell lines | Vero E6 cells (African green monkey kidney epithelial cell line) |
Preparation Method | Vero E6 cells were maintained in Dulbecco's minimal essential medium (DMEM) supplemented with 10% heat-inactivated fetal bovine serum (FBS) at 37°C, 5% CO₂. Cells were pretreated with Hydroxypropyl-beta-cyclodextrin at concentrations of 5-20mM for 1 hour, followed by infection with SARS-CoV-2 (MOI=0.1) for 1 hour. The virus inoculum was then replaced with fresh medium, and cells were cultured for up to 72 hours. |
Reaction Conditions | 5-20mM; 1-hours pretreatment |
Applications | Hydroxypropyl-beta-cyclodextrin pretreatment significantly inhibited SARS-CoV-2 replication, reducing intracellular viral genomic RNA (gRNA) and subgenomic RNA (sgRNA) levels. Hydroxypropyl-beta-cyclodextrin also markedly decreased the production of infectious virus particles, leading to a reduction in viral titer by over 90%. |
| Animal experiment [2]: | |
Animal models | Tg19959 transgenic mice (overexpressing human APP with Swedish and Indiana familial AD mutations) |
Preparation Method | Mice were subcutaneously administered Hydroxypropyl-beta-cyclodextrin (4000mg/kg, 20% w/v solution in isotonic saline) twice weekly, starting at postnatal day 7 (P7) and continuing for 4 months. Control mice received saline injections on the same schedule. |
Dosage form | 4000mg/kg; s.c. |
Applications | Hydroxypropyl-beta-cyclodextrin administration significantly improved spatial learning and memory deficits in the Morris water maze test. Hydroxypropyl-beta-cyclodextrin also markedly diminished Aβ plaque deposition in both the cerebral cortex and hippocampus, and reduced the area occupied by phosphorylated tau (AT8)-immunoreactive dystrophic neurites. |
