Background: 3-Acetyl-11-keto-β-boswellic acid (AKBA) has attracted considerable interest due to its therapeutic potential against inflammatory and cancer-related disorders. However, its poor oral bioavailability remains a critical limitation for clinical application. This study aimed to enhance the bioavailability of AKBA by developing a nanoemulsion (NE)-based delivery system.

Results: Several NE formulations were optimized and characterized based on drug loading, stability, and droplet size. The optimized NE-AKBA showed a droplet size of 12-15 nm, a low polydispersity index, and a zeta potential of - 14.5 mV. Permeability studies revealed significantly improved transport of NE-AKBA across Caco-2 monolayers within the first hour. Pharmacokinetic analysis revealed a notable increase in systemic exposure: Cmax increased from 3.36 to 12.23 µg/mL and AUC0 - t increased from 40.9 to 72.1 µg·h/mL, while Tmax remained unchanged at 6 h, indicating an enhanced extent of absorption without alteration of absorption kinetics.

Conclusion: These findings demonstrate that nanoemulsion-based delivery significantly improves the oral bioavailability of AKBA and provides a promising platform for its future therapeutic development.

背景:3-乙酰基-11-酮-β-乳香酸(AKBA)由于其治疗炎症和癌症相关疾病的潜力而引起了相当大的兴趣。然而,其较差的口服生物利用度仍然是临床应用的关键限制。本研究旨在通过开发纳米乳给药系统来提高AKBA的生物利用度。结果:根据载药量、稳定性和滴度对几种NE制剂进行了优化和表征。优化后的NE-AKBA液滴尺寸为12-15 nm,多分散性指数低,zeta电位为- 14.5 mV。渗透性研究表明,在第一个小时内,NE-AKBA通过Caco-2单层的运输显著改善。药代动力学分析显示,全身暴露量显著增加:Cmax从3.36增加到12.23µg/mL, AUC0 - t从40.9增加到72.1µg·h/mL,而Tmax在6 h时保持不变,表明吸收程度增强,但吸收动力学没有改变。结论:纳米乳化给药可显著提高AKBA的口服生物利用度,为其未来的治疗开发提供了良好的平台。
