JOURNAL OF BIOMATERIALS SCIENCE. POLYMER EDITION 2023; 34:1603-1617. [PMID: 36755525 DOI: 10.1080/09205063.2023.2177473] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/13/2022] [Revised: 01/29/2023] [Accepted: 02/03/2023] [Indexed: 02/10/2023]
Abstract
Tyrosol (TYR) and parthenolide (PLT) have been used as synthetic antioxidant and natural anticancer compounds. In the current study, we aimed to synthesize an encapsulated complex of both PLT and TYR in a hybrid coating layer consisting of lecithin and chitosan molecules, a proper biocompatible drug delivery system to evaluate its antibacterial and anticancer potentials on human liver HepG2 and pancreatic Panc cancer cell lines. The chitosan-lecithin-coated PLT/TYR nanoparticles (clPT-NPs) were synthesized applying an auto-self-assembling method. The clPT-NPs were characterized utilizing DLS, FTIR, zeta potential, and TEM analysis. The clPT-NPs' antioxidant activity was measured by running ABTS and DPPH antioxidant assays. Moreover, the antibacterial potential of clPT-NPs was evaluated by applying disk diffusion, MIC, and MBC assays. Finally, the nanoparticles' cytotoxicity and apoptotic activity were studied by conducting MTT, Flow cytometry, AO/PI cell staining, and real-time PCR techniques. The clPT-NPs (38 nm) exhibited significant antioxidant activity by inhibiting ABTS and DPPH radicals at 187 and 290 μg/mL IC50 concentrations, respectively. Also, the nanoparticles induced a notable antibacterial activity against Staphylococcus aureus at 0.0625 mg/mL MIC and 0.125 mg/mL MBC concentrations. The clPT-NPs selectively decreased the cancer cells' survival and increased the apoptotic dead cells by up-regulating apoptotic gene expression (BAX and Cas-8) and down-regulating BCL-2 anti-apoptotic gene expression. The PLT toxicity has been merged with improved TYR antioxidant activity, which has been functionalized in a safe, biocompatible hybrid nano-delivery system.

Micropropagation of Feverfew (Tanacetum parthenium) and Quantification of Parthenolide Content in Its Micropropagated and Conventionally Grown Plants. HORTICULTURAE 2022.

Abstract
Feverfew (Tanacetum parthenium) is a well-known multi-functional plant with anti-inflammatory, cardiotonic, antiangiogenic, and anticancer effects. The therapeutic value of this plant is due to its phytochemical constitutes, especially parthenolide. Tissue culture techniques have been applied to improve the bioactive components of many herbal plants. Hence, this study, was carried out to establish a protocol for micropropagation of the feverfew plant and to quantify parthenolide content in its micropropagated and conventionally grown plants. To establish an aseptic culture, different concentrations of sodium hypochlorite (NaOCl) were investigated for seed surface sterilization. Besides, the effects of plant growth regulators (PGRs) on the callus induction, shoot organogenesis from callus and in vitro rooting were evaluated. Additionally, the parthenolide yield of the micropropagated and conventionally grown plants was determined by using high-performance liquid chromatography (HPLC). The results showed that surface sterilization of feverfew seeds with 6% NaOCl for 15 min obtained 65.00 ± 2.69% aseptic seeds. Murashige and Skoog (MS) medium supplemented with 0.4 mg/L thidiazuron (TDZ) and 2 mg/L 2,4-dichlorophenoxy acetic acid (2,4-D) resulted in 86.00 ± 1.72% callus induction. The highest number of shoots (5.00 ± 0.15) per explant was obtained in the treatment of MS medium supplemented with 5 mg/L zeatin. MS medium fortified with 3 mg/L indole-3-butyric acid (IBA) produced the maximum number of roots per plantlet (8.90 ± 0.35). A total of 90% of the micropropagated plantlets survived when planted in perlite + peat moss (1:1 v/v); the micropropagated plantlets were successfully established in the ex vitro conditions. According to parthenolide analysis, its level was significantly higher in the micropropagated plants than conventionally grown plants. Among different solvents, ethanolic extraction obtained the highest parthenolide content of the feverfew plant. Hence, it can be concluded that micropropagation of feverfew could be applied to produce disease-free planting materials and to improve the parthenolide content of the feverfew plant.

Derivatisation of parthenolide to address chemoresistant chronic lymphocytic leukaemia. MEDCHEMCOMM 2019; 10:1379-1390.

Abstract
Parthenolide is a natural product that exhibits anti-leukaemic activity, however, its clinical use is limited by its poor bioavailability. It may be extracted from feverfew and protocols for growing, extracting and derivatising it are reported. A novel parthenolide derivative with good bioavailability and pharmacological properties was identified through a screening cascade based on in vitro anti-leukaemic activity and calculated "drug-likeness" properties, in vitro and in vivo pharmacokinetics studies and hERG liability testing. In vitro studies showed the most promising derivative to have comparable anti-leukaemic activity to DMAPT, a previously described parthenolide derivative. The newly identified compound was shown to have pro-oxidant activity and in silico molecular docking studies indicate a prodrug mode of action. A synthesis scheme is presented for the production of amine 7 used in the generation of 5f.
