Solubility of Piperine and Its Inclusion Complexes in Biorelevant Media and Their Effect on Attenuating Mouse Ileum Contractions. ACS OMEGA 2021; 6:6953-6964. [PMID: 33748609 PMCID: PMC7970567 DOI: 10.1021/acsomega.0c06198] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/21/2020] [Accepted: 02/18/2021] [Indexed: 06/12/2023]
Abstract
This study evaluated the solubility of piperine (PP) in biorelevant media and the effect of its ground mixtures (GMs) and coprecipitates (CPs) on intestinal contractions when presented in inclusion complexes with α-, β-, and γ-cyclodextrins (CDs). In the powder X-ray diffraction (PXRD) and differential scanning calorimetry (DSC) measurements, CP (PP/αCD) and CP (PP/γCD) suggest the formation of inclusion complexes. The 1H-nuclear magnetic resonance (NMR) analysis showed the integrated intensity ratios of CP (PP/αCD) and CP (PP/γCD) protons to be 1/2 and 1/1, the same as the respective molar ratios in the respective GM inclusion complexes. The intestinal contraction test confirmed that the intestinal contraction rate of carbachol (CCh) in the presence of 2.0 × 10-5 M PP was comparable to that in the absence of PP. On the other hand, CP (PP/αCD), GM (PP/αCD = 1/2), and GM (PP/βCD = 1/1) formed inclusion complexes that significantly suppressed the intestinal contractility at PP 1.0 × 10-8 M. No significant differences were observed between CP and GM. The solubility of the PP/αCD inclusion complex was 6-7 times higher than that of PP in the fasted-state-simulated intestinal fluid (FaSSIF, pH 6.5). PP functioned to suppress intestinal contraction by forming an inclusion complex. Based on this result, PP/αCD might be expected to be effective as an antidiarrheal.

Abstract
A polyrotaxane (PR) with poly(methyl methacrylate) (PMMA) as the main chain polymer was prepared via reversible addition-fragmentation chain transfer (RAFT) polymerization. Because of the special mechanism of RAFT, the suprastructure of a PMMA-based PR is established by synthesizing inclusion complexes of methyl methacrylate and gamma-cyclodextrin (γCD) into the middle of the poly-N-(3-dimethylamino) propyl methacrylamide segments. The presence of threaded γCD was determined via diffusion ordered spectroscopy from the alignment of the mobility of γCD and the main chain polymer. A PMMA-based PR with 2-20% CD coverage and a molecular weight of 7K-60K g/mol of PMMA-based PR was synthesized with a targeted molecular structure by mediating the RAFT polymerization. The PMMA-based PR prepared in this study is expected to be suitable for wide applications of tough materials with good heat resistance. Moreover, the investigation of this synthetical approach opened possibilities for more variety of PR with controllable properties.

Evaluation of the Molecular State of Piperine in Cyclodextrin Complexes by Near-Infrared Spectroscopy and Solid-State Fluorescence Measurements. INTERNATIONAL JOURNAL OF MEDICINAL CHEMISTRY 2019; 2019:7530480.

Abstract
The purpose of this study was to evaluate the physicochemical properties of piperine (PP) in ground mixtures (GMs) of PP with α-, β-, or γ-cyclodextrin (CD) under conditions of humidity, heat, and humidity-heat. In solid-state fluorescence measurements, the fluorescence maxima for GM (PP/αCD = 1/2), GM (PP/βCD = 1/1), and GM (PP/γCD = 1/1) were observed at 463, 472, and 469 nm, respectively. On the other hand, the humidified GMs exhibited maxima at 454, 460, and 465 nm, while the humidified-heated samples displayed fluorescence maxima at 455, 455, and 469 nm, respectively. Therefore, the molecular behavior of PP with α, β, and γCD was concluded to vary upon the coordination of water molecules. NIR and solid-state fluorescence measurements revealed that the molecular behavior of PP inside the α, β, and γCD cavity changed by water and heat factors depends on the mobility of the methylenedioxyphenyl group.
