    Structure and composition

    The sodium sulfobutylbetacyclodextrin produced by us is β- The product of substitution reaction between cyclodextrin and 1,4-butanesulfolactone. Betacyclodextrin glucose unit is formed by connecting 7-pyranoglucose through a-1 and 4-glycosidic bonds, and the substitution reaction takes place in β- At the 2,3,6 carbon hydroxyl position of the CD glucose unit, the obtained product is SBECD with a degree of substitution of 6.2-6.9.

    Product features

    It can be used as solubilizer, wetting agent, chelating agent (complexing agent) and multivalent masking agent. Sulfobutylbetacyclodextrin sodium is a new type of anionic highly water-soluble cyclodextrin derivative, which can be well combined with drug molecules to form a non covalent complex, thus improving the stability, water solubility and safety of the drug, reducing renal toxicity, easing drug hemolysis, controlling drug release rate, covering bad smell, etc. It has good solubilization, convenient administration, safety and stability. Betacyclodextrin( β- CD).  In contrast, sulfobutylbetacyclodextrin sodium has good water solubility, small hemolysis and low nephrotoxicity, so it is a new pharmaceutical excipient with very broad application prospects.

    Product performance

    1. Solubility:

    Neutral, positive and negative APIs can effectively combine with sulfobutylbetacyclodextrin, which can increase the solubility of compounds in the API water by 10 to 25000 times.

    2. Convenient administration:

    Sulfobutylbetacyclodextrin has good biocompatibility and can be administered by injection, oral administration, eye, nose, external use and inhalation.

    3. Good safety:

    Generally, it can be eliminated from the kidney rapidly and completely after administration. In vitro and in vivo acute, metastable and chronic toxicity studies provide safe data and are approved for human drug preparations.

    4. Good stability:

    The interaction with sulfobutylbetacyclodextrin can provide a beneficial protection environment for the API in its lipophilic cavity, while the water-resistant surface provides excellent water solubility and stability.

    Case application

    Sulfobutylbetacyclodextrin sodium is commonly used in insoluble compounds, such as voriconazole, capezolomide, ziprasidone, aripiprazole, maropenitan (animal medicine), posaconazole, carbamazepine, mefalen, deloxacin, mebendazole, topiramate, omeprazole, clopidogrel, docetaxel, sofibuvir, ziprasidone mesylate, levo phenylalanine mustard, meloxicam Tetrahydroprogesterone and several other nitrogen-containing APl bases are at different clinical stages.

    Sulfobutyl currently marketed by FDA- β- Cyclodextrin sodium inclusion complex injection mainly includes:

    Voriconazole (trade name: Vfend)

    Ziprasidone (trade name: Geodon)

    Posaconazole (trade name: Noxafil)

    Remdesivir for injection has started the phase III clinical study of anti new coronary disease (2019 nCoV) in Beijing Sino Japan Friendship Hospital. Gilead has done a lot of research on the dose and safety of Remdisivir. At the clinical dose, Remdesivir shows good overall safety, except for its impact on liver function. Redcevir freeze-dried preparation also contains the following non active ingredients: water for injection, sulfobutyl- β- Sodium cyclodextrin (SBECD), adjust the pH of the preparation to 3.0-4.0 with HCL and/or NAOH, and then freeze dry. According to the current stability data, the freeze-drying can be kept below 30 ℃ for three years.
