Abstract
This research planned to ameliorate an aqueous solubility and dissolution of Curcumin (CUR) by the formulation of inclusion complex with β-cyclodextrin (β-CD) and polyvinylpyrrolidone (PVP). The phase solubility study was performed to assess the solubility of CUR. The prepared CUR complex assessed for dissolution study, physicochemical evaluation, in-vitro antioxidant activity, molecular modeling, and anti-inflammatory assessment. The pivotal findings of phase-solubility studies demonstrate apparent stability constant (Kc) and complexation efficiency (CE) values for CUR-β-CD and CUR-β-CD-PVP complex was 175.4 M -1, 1.15% and 833.3.2 M -1 and 5.21%, respectively. The characterization results revealed amorphization of crystalline state (CUR) into amorphous state. The maximum drug release found with the ternary CUR complex (F7), i.e. 45.41 ± 3.78% in 6 h study. The chemical shift in the NMR supports that the aromatic ring of CUR is completely complexed inside the β-CD cavity. The antioxidant activity of pure CUR was found to be 58.02 ± 2.21% and CUR ternary complex (F7) showed significantly higher activity to 96.02 ± 2.46%. The in-vivo effect of CUR complex (F7) was also found significantly higher than that of pure CUR. The molecular modeling study depicted that PVP increased the stability of the ternary complex by forming the link between CUR and β-CD. Thus, the ternary inclusion complex of CUR-β-CD-PVP could contribute as an innovative outcome in the enhancement of solubility and in-vivo activity.

Stimulatory Effects of Soluplus® on Flufenamic Acid β-Cyclodextrin Supramolecular Complex: Physicochemical Characterization and Pre-clinical Anti-inflammatory Assessment. AAPS PharmSciTech 2020; 21:145. [PMID: 32430787 DOI: 10.1208/s12249-020-01684-2] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2020] [Accepted: 04/11/2020] [Indexed: 01/02/2023] Open
Abstract
The present study demonstrates the solubility and dissolution of flufenamic acid (FLF)/β-cyclodextrin (β-CD)/Soluplus® supramolecular ternary inclusion complex. The binary and ternary inclusion complexes were prepared using solvent evaporation and the microwave irradiation method. The prepared inclusion complexes were evaluated for physicochemical characterization and anti-inflammatory activity using a murine paw edema mol. The phase solubility studies demonstrated 4.59-fold and 17.54-fold enhancements in FLF solubility with β-CD alone and β-CD:Soluplus® combination compared with pure FLF, respectively. The in vitro drug release results revealed a significant improvement (P < 0.05) in the release pattern compared with pure FLF. Maximum release was found with flufenamic acid binary and ternary complexes prepared using the microwave irradiation method, i.e., 75.23 ± 3.12% and 95.36 ± 3.23% in 60 min, respectively. The physicochemical characterization results showed complex formation and conversion of the crystalline form of FLF to an amorphous form. The SEM study revealed the presence of a more agglomerated and amorphous structure of the solid particles, which confirmed the formation of complexes. The anti-inflammatory effect of the complex was higher than pure FLF. Therefore, the FLF:β-CD:Soluplus® inclusion complex may be a very valuable formulation with improved solubility, dissolution, and anti-inflammatory effect.

Abstract
Progesterone (PGT) is a natural hormone that stimulates and regulates various important functions, such as the preparation of the female body for conception and pregnancy. Due to its low water solubility, it is administered in a micronized form and/or in vehicles with specific solvents requirements. In order to improve the drug solubility, inclusion complexes of PGT and β-cyclodextrins were obtained by the freeze-drying method. Two β-cyclodextrins (native and methylated) in two solvents (water and water:ethanol) and different molar ratio of the reagents were the variables tested for the selection of the best condition for the preparation of the complexes. The PGT/randomly methylated-β-cyclodextrin complexes were incorporated into chitosan thermosensitive hydrogels, as an alternative formulation for the vaginal administration of PGT. Neither the micro and macroscopic characteristics of the gels nor the transition time from solution to gel were modified after the complexes incorporation. In addition, chitosan gels with complexes resisted better the degradation in simulated vaginal fluid in comparison to commercial gel (Crinone®). The chitosan gel with inclusion complexes and Crinone® were tested in vitro in a diffusion assay to evaluate the delivery of the hormone and its diffusion through porcine epithelial mucosa obtained from vaginal tissue. Chitosan gel presented sustained diffusion similar to the exhibited by commercial gel. The use of chitosan gels with inclusion complexes based on cyclodextrins would be a viable alternative for vaginal administration of PGT.

Abstract
The cyclodextrins (CDs) complexation technique was performed for the enhancement of hydroxylation yield from dehydroepiandrosterone (DHEA) by Colletotrichum lini ST-1. Using DHEA/methyl-β-cyclodextrin (M-β-CD) or DHEA/hydroxypropyl-β-cyclodextrin (HP-β-CD) inclusion complexes as substrate (10g/L), the hydroxylation yields were increased by 14.98% and 20.54% respectively, and the biotransformation course was shortened by 12h. X-ray diffractometry, differential scanning calorimetry, and phase solubility analyses showed an inclusion complex was formed between CDs and DHEA at a molar ratio of 1:1, which remarkably increased the solubility of DHEA, and then improved substrate biotransformation efficiency and hydroxylation yield. Meanwhile, results of thermodynamic parameters (ΔG, ΔH, ΔS and Ks) analysis revealed the complexation process was spontaneous and DHEA/CDs inclusion complex was stable. Scanning electron microscopy and transmission electron microscopy showed that the enhancement of DHEA hydroxylation yield also depended on the improvement of cell permeability through interaction between cytomembrane and CDs. These results suggested that the CDs complexation technique was a promising method to enhance steroids hydroxylation yield by increasing steroids solubility and decreasing membrane resistance of substrate and product during biotransformation process.
