Abstract
10-HCPT is a topoisomerase I inhibitor effective in the treatment of liver cancer but its use is hampered by its resistance. The expression of hypoxia-inducible factor-1α (HIF-1α) is reportedly upregulated in liver cancer tissues, which is directly linked to the resistance of 10-HCPT. While BBR can significantly decrease the level of HIF-1α according to the literature report. Thus, the aim of this study was to prepare a novel intravenous 10-HCPT-BBR-loaded lipid microsphere (LM) and evaluate their synergistic effect on liver cancer treatment. The optimal preparation mainly included 10.0% oil phase (medium-chain triglyceride:long-chain triglyceride = 1:1), emulsifier (egg lecithin E80 and pluronic F68), antioxidant (0.02% NaHSO3), and pH regulator (0.1 mol/L Hcl). Then, the behaviors of BBR-10-HCPT loaded LM in vitro and in vivo were systematically investigated. In vitro, it showed an obvious sustained-release effect in different release mediums, good physicochemical stability at accelerated and long-term storage conditions, and great anti-proliferative capability toward human liver cancer Hep-3B cells. In vivo, the prepared LM exhibited a longer half-life and higher AUC compared to BBR injection and 10-HCPT injection. More importantly, it was found that The LM was distributed more in the liver, spleen, and tumors, but less in the lungs and heart, especially in the lung. And then, it showed significant inhibition of tumor growth against nude mouse with Hep-3B tumor, and the tumor inhibition rate reached 91.55%. Thus, the data obtained in our study suggested that BBR combined with 10-HCPT can raise curative effect and reduce the toxicity of 10-HCPT.

Int J Pharm 2021; 604:120729. [PMID: 34029666 DOI: 10.1016/j.ijpharm.2021.120729] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2021] [Revised: 05/05/2021] [Accepted: 05/19/2021] [Indexed: 10/21/2022]
Abstract
This study developed a nanocrystals-in-microparticles (NCs/MPs) technology for improving dissolution and oral absorption of poorly soluble drugs. Hydroxycamptothecin (HCPT) was selected as a model drug and prepared to be nanocrystals (HCPT-NCs) by acid-alkali based precipitation. The HCPT-NCs were rod like shape with the length of 250 nm and the width of 50 nm. Then, the chitosan and sodium alginate were selected as microparticles matrix to encapsulate the HCPT-NCs. The HCPT-NCs were entrapped in microparticles with a D50 value of 15 µm. The drug loading capacity of microparticles achieved more than 40% (w/w) by NCs/MPs technology. The powder X-ray diffraction showed the crystal structure of HCPT in microparticles was same as nanocrystals, indicating that the preparation of microparticles could not destroy the nanocrystals. The in vitro release demonstrated that microparticles could protect the NCs in gastric fluid and release NCs in intestinal fluid. Furthermore, the oral bioavailability of HCPT in NCs/MPs was improved by 18-fold compared to bulk HCPT and 2.1-fold compared to HCPT-NCs as tested by a rat model. Therefore, NCs/MPs technology is a promising and high effective approach to improve the oral bioavailability of poorly soluble drugs.

Abstract
Chemotherapy outcomes for the treatment of glioma remains unsatisfactory due to the inefficient drug transport across the blood-brain barrier (BBB) and insufficient drug accumulation in the tumor region. Although many approaches, including various nanosystems, have been developed to promote the distribution of chemotherapeutics in the brain tumor, the delivery efficiency and the possible damage to the normal brain function still greatly restrict the clinical application of the nanocarriers. Therefore, it is urgent and necessary to discover more safe and effective BBB penetration and glioma-targeting strategies. In the present study, menthol, one of the strongest BBB penetration enhancers screened from traditional Chinese medicine, was conjugated to casein, a natural food protein with brain targeting capability. Then the conjugate self-assembled into the nanoparticles to load anti-cancer drugs. The nanoparticles were characterized to have appropriate size, spheroid shape and high loading drug capacity. Tumor spheroid penetration experiments demonstrated that penetration ability of menthol-modified casein nanoparticles (M-CA-NP) into the tumor were much deeper than that of unmodified nanoparticles. In vivo imaging further verified that M-CA-NPs exhibited higher brain tumor distribution than unmodified nanoparticles. The median survival time of glioma-bearing mice treated with HCPT-M-CA-NPs was significantly prolonged than those treated with free HCPT or HCPT-CA-NPs. HE staining of the organs indicated the safety of the nanoparticles. Therefore, the study combined the advantages of traditional Chinese medicine strategy with modern delivery technology for brain targeting, and provide a safe and effective approach for glioma therapy.

Abstract
10-Hydroxy camptothecin (10-HCPT) is an antitumor agent effective in the treatment of several solid tumors but its use is hampered by poor water solubility, low lactone stability, short plasma half-life and dose-limiting toxicity. These limits of 10-HCPT had been overcome by our group through preparing super macromolecule prodrug: 10-HCPT-hydroxyethyl starch (HES) conjugate. In this study, we mainly evaluated in vitro and in vivo behavior of the prodrug, containing cytotoxicity assay, pharmacodynamics study, vascular irritation test, hemolysis experiment and tissue distribution test of rats. The irritation test results achieved much lower irritation than the commercial injection. The tissue distribution results showed that HES-10-HCPT conjugate increased significantly the 10-HCPT concentration in the tumor, liver and spleen site, whereas decreased the drug concentration in the heart and kidney. The hemolysis effect of the prepared conjugate was not obvious. The pharmacodynamics results indicated that HES-10-HCPT prodrug had a better antitumor efficiency against mice with H22 tumor than the commercial injection, and the inhibition ratio of tumor was 85.2% and 31.1%, respectively at the same dosage. These findings suggest that HES-10-HCPT prodrug is a promising drug delivery system providing improved good injection safety, greater tolerance and antitumor effect.

Abstract
10-hydroxy camptothecin (10-HCPT) is an antitumor agent effective in the treatment of several solid tumors but its use is hampered by poor water solubility, low lactone stability, short plasma half-life and dose-limiting toxicity. In this study, 10-HCPT-hydroxyethyl starch (HES) conjugate was prepared to overcome these limits of 10-HCPT. The solubility of 10-HCPT conjugate was 0.72 mg/ml, about 100 times to free 10-HCPT. The 10-HCPT conjugate showed good sustained release effect in phosphate-buffered saline (PBS), rat plasma and liver homogenate. Meanwhile, 10-HCPT-HES conjugate achieved much lower IC50 and higher cytotoxicity effects than the free 10-HCPT on Hep-3B liver cancer cells. The pharmacokinetics results of 10-HCPT-HES conjugate demonstrated that the biological half-life of 10-HCPT was increased from 10 min to 4.38 h and the bioavailability was 40 times higher than the commercial 10-HCPT injection. The pharmacodynamics results indicated that 10-HCPT-HES conjugate had a better antitumor efficiency against nude mouse with Hep-3B tumor than the commercial 10-HCPT injection, and the inhibition ratio of tumor was 83.9 and 27.8%, respectively, at the same administration dosage. These findings suggest that 10-HCPT-HES conjugate is a promising drug delivery system providing improved long circulating effect, greater stability and better antitumor effect.
