Abstract
Cyclodextrins (CDs) are versatile agents used to solubilize small drugs and stabilize proteins. This dual functionality may be particularly beneficial for antibody-drug conjugates (ADCs), as CDs may "mask" the hydrophobicity of the drug payloads. In this study, we explored the effect of CDs on the physical stability of ADCs composed of the same antibody but with different payloads (maytansinoid, auristatin, and fluorophore payloads). The aggregation of ADCs was evaluated under shaking stress conditions and elevated temperatures using size-exclusion chromatography, turbidity, and backgrounded membrane imaging. Our results showed that hydroxypropyl-(HP)-CDs effectively stabilized all ADCs during shaking stress, with increasing stabilization in the order of HPαCD < HPγCD < HPβCD at concentrations of 7.5 mM and (near) complete stabilization at 75 mM. Native CDs without surface activity also stabilized certain ADCs, although less effectively than HP-CDs under agitation stress. During quiescent incubation, the HP-CD effects were small for most ADCs. However, for an ADC with a fluorophore payload that rapidly aggregated after conjugation, HPγCD substantially reduced aggregate levels, in line with fluorescence data supporting CD-ADC interactions. In contrast, sulfobutylether-β-CD (SBEβCD) increased the aggregation rates in all ADCs under all stress conditions. In conclusion, this study highlights the potential of appropriate CD formulations to improve the physical stability of ADCs.

[PMID: 38494236 DOI: 10.1016/j.carbpol.2024.121985] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2024] [Revised: 02/06/2024] [Accepted: 02/23/2024] [Indexed: 03/19/2024]
Abstract
Sodium Sulfobutylether-β-cyclodextrin (SBE-β-CD) is a derivative of β-cyclodextrin, characterized by its stereo structure, which closely resembles a truncated cone with a hydrophobic internal cavity. The solubility of insoluble substances within the hydrophobic cavity is significantly enhanced, reducing contact between the guest and the environment. Consequently, SBE-β-CD is frequently employed as a co-solvent and stabilizer. As the research progresses, it has been observed that the inclusion of SBE-β-CD is reversible and competitive. Besides, some inclusion complexes undergo distinct physicochemical property alterations compared to the guests. Additionally, certain guests exhibit varying inclusions with SBE-β-CD at different concentrations. These features have contributed to the expanding applications. SBE-β-CD finds widespread application in pharmaceutics as a protective agent and pKa regulator, in pharmaceutical analysis as a chiral substance separator, and in biomedical engineering for encapsulating dyes and modifying sensors. The article will elaborate in detail on the physicochemical properties of SBE-β-CD, encapsulation principles, and factors influencing the formation of inclusion complexes. Furthermore, the review focuses on the application of SBE-β-CD through encapsulation in pharmaceutics, pharmaceutical analysis, and biomedical engineering. Finally, the prospects and potential applications of SBE-β-CD are discussed.

Inclusion complex of quercetin with sulfobutylether β-cyclodextrin: preparation, characterization, antioxidant and antibacterial activities and the inclusion mechanism. RSC Adv 2024; 14:9472-9481. [PMID: 38516163 PMCID: PMC10951979 DOI: 10.1039/d3ra08936c] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2023] [Accepted: 02/29/2024] [Indexed: 03/23/2024] Open
Abstract
Quercetin (QCT) has a variety of pharmacological effects, such as antioxidant, antibacterial, anticancer, anticardiovascular and antiaging effects. However, its poor water solubility, stability and bioavailability limit its applications. The special structure of cyclodextrins and their derivatives with a hydrophobic inner cavity and hydrophilic outer wall can load a variety of hydrophobic drugs of a suitable size and shape, thereby improving the stability and solubility of these molecules. In this study, an inclusion complex of quercetin and sulfobutylether-β-cyclodextrin was prepared. It was characterized via FT-IR, UV, 1H NMR, XRD, DSC, and SEM analysis, which revealed the successful formation of the inclusion complex. In vitro biological activity estimations were carried out and the results indicated that the inclusion complex displayed higher antioxidative and antibacterial properties compared with free QCT. In addition, the mechanisms of inclusion were explored using 1H NMR analysis and docking calculations, thus providing a theoretical basis for obtaining an inclusion complex.

Leveraging the use of in vitro and computational methods to support the development of enabling oral drug products: An InPharma commentary. Eur J Pharm Sci 2023; 188:106505. [PMID: 37343604 DOI: 10.1016/j.ejps.2023.106505] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/13/2023] [Revised: 06/18/2023] [Accepted: 06/19/2023] [Indexed: 06/23/2023]
Abstract
Due to the strong tendency towards poorly soluble drugs in modern development pipelines, enabling drug formulations such as amorphous solid dispersions, cyclodextrins, co-crystals and lipid-based formulations are frequently applied to solubilize or generate supersaturation in gastrointestinal fluids, thus enhancing oral drug absorption. Although many innovative in vitro and in silico tools have been introduced in recent years to aid development of enabling formulations, significant knowledge gaps still exist with respect to how best to implement them. As a result, the development strategy for enabling formulations varies considerably within the industry and many elements of empiricism remain. The InPharma network aims to advance a mechanistic, animal-free approach to the assessment of drug developability. This commentary focuses current status and next steps that will be taken in InPharma to identify and fully utilize 'best practice' in vitro and in silico tools for use in physiologically based biopharmaceutic models.

Abstract
The understanding of the relationship between molecular structure and the thermodynamics of host-guest binding is essential for the rational design of the applications of inclusion complexes. To obtain insight into the factors governing the driving force of complex formation in aqueous solutions, the encapsulation of five pharmaceutically important protoberberine alkaloids was studied in sulfobutylether-β-cyclodextrin having on average 6.4 degrees of substitution (SBE6.4βCD). Spectrophotometric, fluorescence spectroscopic, and isothermal calorimetric measurements showed 1:1 complexation in dilute solutions. From 1.92 × 104 M−1, about an eight-fold decrease of the association constant was observed in the series of berberine ≈ coptisine >> palmatine > epiberberine > dehydrocorydaline. The embedment of these alkaloids in the SBE6.4βCD cavity was entropy-controlled with mildly negative enthalpy contributions. These findings suggest that the stabilization of the examined complexes arises primarily from the hydrophobic interaction between the constituents. The more than three orders of magnitude smaller association constants of protoberberine alkaloids with SBE6.4βCD than with cucurbit[7]uril, a host having similar cavity size, originates from the much smaller exothermicity of the confinement in the former macrocycle.
