Berberine is a plant-origin quaternary isoquinoline alkaloid with a vast array of biological activities, including antioxidant and blood-glucose- and blood-lipid-lowering effects. However, its therapeutic potential is largely limited by its poor oral bioavailability. The aim of this study was to investigate the in vitro solubility and Caco-2 cell permeability followed by pharmacokinetic profiling in healthy volunteers of a new food-grade berberine delivery system (i.e., Berberine LipoMicel). X-ray diffractometry (XRD), in vitro solubility, and Caco-2 cell permeability indicated higher bioavailability of LipoMicel Berberine (LMB) compared to the standard formulation. Increased aqueous solubility (up to 1.4-fold), as well as improved Caco-2 cell permeability of LMB (7.18 × 10 ± 7.89 × 10 cm/s), were observed when compared to standard/unformulated berberine (4.93 × 10 ± 4.28 × 10 cm/s). Demonstrating better uptake, LMB achieved significant increases in AUC and C compared to the standard formulation (AUC: 78.2 ± 14.4 ng h/mL vs. 13.4 ± 1.97 ng h/mL, respectively; < 0.05; C: 15.8 ± 2.6 ng/mL vs. 1.67 ± 0.41 ng/mL) in a pilot study of healthy volunteers ( = 10). No adverse reactions were reported during the study period. In conclusion, LMB presents a highly bioavailable formula with superior absorption (up to six-fold) compared to standard berberine formulation and may, therefore, have the potential to improve the therapeutic efficacy of berberine. The study has been registered on ClinicalTrials.gov with Identifier NCT05370261.
黄连素是一种植物源季铵型异喹啉生物碱,具有广泛的生物活性,包括抗氧化以及降血糖和降血脂作用。然而,其治疗潜力在很大程度上受到口服生物利用度差的限制。本研究的目的是研究一种新型食品级黄连素递送系统(即黄连素脂质微球)的体外溶解度和Caco-2细胞通透性,随后在健康志愿者中进行药代动力学分析。X射线衍射法(XRD)、体外溶解度和Caco-2细胞通透性表明,与标准制剂相比,脂质微球黄连素(LMB)具有更高的生物利用度。与标准/未配制的黄连素(4.93×10±4.28×10 cm/s)相比,LMB的水溶性增加(高达1.4倍),同时Caco-2细胞通透性也有所改善(7.18×10±7.89×10 cm/s)。在一项针对10名健康志愿者的初步研究中,LMB表现出更好的吸收,与标准制剂相比,其AUC和C显著增加(AUC:分别为78.2±14.4 ng·h/mL和13.4±1.97 ng·h/mL;P<0.05;C:15.8±2.6 ng/mL和1.67±0.41 ng/mL)。研究期间未报告不良反应。总之,与标准黄连素制剂相比,LMB具有高生物利用度配方和卓越的吸收性(高达六倍),因此可能有潜力提高黄连素的治疗效果。该研究已在ClinicalTrials.gov上注册,标识符为NCT05370261。
