This versatility is partly due to the potential of tailoring NPs from multiple sources. Notably, saponins, amphiphilic plant metabolites, have shown great promise in NP formulation. This study explored the development of micellar NPs using saponin crude fractions (SCFs) extracted from five Congolese plant species: <em>Millettia laurentii, Penthaclethra eetveldeana</em>, <em>Schwenckia americana</em>, <em>Musa paradisiaca,</em> and <em>Musa sapientum</em>. Plant materials were subjected to histological examination through optical microscopy, while phytochemical analyses by thin-layer chromatography confirmed the presence and predominance of saponins in the SCFs. We used a phthalocyanine-isoniazid hybrid (<em>Pc</em>-INH) as a hydrophobic probe to determine the critical micellar concentrations of SCFs and explore the feasibility of developing cost-effective saponin-based micelles (SBMs). Phytochemical screenings indicated saponins in the extracted SCF and other metabolites like flavonoids, phenolic acids, and anthocyanins. Dynamic light scattering and transmission electron microscopy analyses revealed the formation of nano-sized particles, particularly noting SBMs from <em>P. eetveldeana</em> with notable dimensions (157 ​nm, PDI of 0.27, and ZP of −4.01 ​mV) and spherical shape. The micelles from <em>M. laurentii</em> exhibited superior encapsulation efficiency for <em>Pc</em>-INH (55%) compared to control micelles formulated from pure saponin (33%). <em>In vitro</em> tests showed that <em>M. paradisiaca</em> SBMs have the best safety profile for red blood cells, with a 10% hemolysis rate compared to a 150% rate for bulk SCFs. However, there is a significant difference between SCFs and SBMs (<em>p</em> ​&lt; ​0.0001). The release profiles of <em>M. paradisiaca</em> SBMs show a pH-dependent relationship, suggesting potential for stimuli-responsive drug delivery. This work lays the foundation for leveraging plant-derived crude saponins in nanotechnology, emphazising their encapsulation efficiency, controlled release potential, and biocompatibility, paving the way for the cost-effective production of high-value biomedical NPs.</div></div>","PeriodicalId":101012,"journal":{"name":"Pharmaceutical Science Advances","volume":"2 ","pages":"Article 100055"},"PeriodicalIF":0.0,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142654967","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The development of tyrosine kinase inhibitors (TKIs) has revolutionized CML treatment; however, resistance and intolerance to these drugs remain key challenges. CML stem cells (CMLSCs) are the root cause of CML relapse and resistance to TKIs. This review discusses novel targeted therapeutic options targeting CMLSCs to address the abovementioned challenges. Numerous novel TKIs, such as flumatinib, vodobatinib, and olverembatinib, have shown remarkable potential against BCR-ABL1, but few, including AT9283, MK0457, and DCC-2036, are still undergoing clinical trials. Targeting CMLSCs is a fundamental therapeutic approach for the treatment of CML progression, relapse, and TKI resistance. In this review, novel agents targeting core signaling pathways and novel molecular targets in CMLSCs are highlighted. Currently, multiple approaches, such as targeting epigenetic modifications or microRNAs and altering metabolism in leukemic cells, have shown desirable effects in treating CML. Immunotherapy, autophagy inhibitors, and protein synthesis inhibitors are novel and effective therapies for the treatment of CML. Although various therapeutic strategies have provided exceptional results in the treatment of CML, the challenges of TKI resistance and CML remission or relapse remain.

However, its therapeutic potential as an antidote against APAP-induced hepatotoxicity has yet to be proven in a clinically relevant model. This study aimed to verify the efficacy of delayed treatment with the hydroethanolic extract of <em>K. grandifoliola</em> (KgE) in suppressing the early injury phase of APAP pathophysiology. KgE was analyzed using HPLC/UV. Acute oral toxicity tests were conducted in mice to determine the therapeutic dose of KgE. Mice were treated with 300 ​mg/kg APAP; 1h and 12h later, they were treated with either predetermined doses of KgE or 20 ​mg/kg c-Jun N-Terminal Kinase (JNK) inhibitor SP600125, which served as a reference antidote. At 6h and 24h after APAP treatment, the parameters of liver damage and mitochondrial dysfunction, phosphorylation of JNK, and mitochondrial translocation were assessed. KgE at a dose of 5000 ​mg/kg was safe for mice. Accordingly, 100, 200, and 400 ​mg/kg were selected as curative treatments. Delayed administration of KgE reversed the histopathological changes in the liver, inhibited serum levels of alanine aminotransferase, reduced the liver content of nitric oxide and malondialdehyde, and restored hepatic glutathione pools and superoxide dismutase and catalase activities in APAP-intoxicated mice. Moreover, KgE prevented APAP-induced JNK phosphorylation and p-JNK mitochondrial translocation and rescued the activities of mitochondrial enzyme complexes II and V.

In this study, an improved thin-film dispersion and post-insertion anchoring technique was utilized to construct a dual-targeted co-delivery SOR and docetaxel (DTX) liposome drug delivery system, folate/chondroitin sulfate with SOR/DTX-modified liposomes (FA/CS@SDLP), to jointly enhance the anti-recurrence and metastasis of HCC. FA/CS@SDLP can establish the gradual release of the two drugs because of successful lysosomal escape in the condensed hyaluronidase environment. The results indicated that modification with folate (FA) and chondroitin sulfate (CS) significantly enhanced the cellular uptake of FA/CS@SDLP and the internalization of SOR/DTX in HepG2 cells through FA and CD44 receptor-mediated endocytosis. Compared to free drugs or the mono-targeted liposomal system (FA@SDLP), FA/CS@SDLP presented higher potency against HepG2 cells regarding pro-apoptosis, anti-proliferation, and anti-metastasis (migration and invasion). Moreover, a more satisfactory antitumor efficacy was observed for FA/CS@SDLP in the pulmonary metastasis of HCC in a mouse model.
