Appl Biochem Biotechnol
September 2024
The present study aims to obtain manganese ferrite nanoparticles functionalized with chitosan (C-MNP) or ethylenediamine (E-MNP) by coprecipitation and polyol one-step methods, characterize their interaction with S. griseus demonstrating cell immobilization, and evaluate the antimicrobial activity of the free cell extracts obtained from immobilized S. griseus fermentation in the presence of different concentrations of MNP.

Due to a large number of signaling pathways regulating GBM pathogenesis, one of the promising directions is development of novel anti-glioblastoma compounds based on natural metabolites capable of affecting multiple targets. Here, we investigated the antitumor potential of the semisynthetic triterpenoid soloxolone tryptamide (STA) against human glioblastoma U87 cells.

- Modifying triterpenoids with amines can enhance their pharmacological properties; this study focuses on 11 new amide derivatives of soloxolone methyl, a compound derived from glycyrrhetinic acid.
- The derivatives showed significant toxicity against tumor cells but did not increase cytotoxicity compared to the original compound; however, they did have the ability to cross the blood-brain barrier effectively.
- One specific derivative, soloxolone tryptamide, demonstrated strong anti-glioblastoma effects in both in vitro cell studies and in vivo mouse models, making it a promising candidate for glioblastoma drug development.
Article Synopsis
- The review outlines the characteristics of colloidal and vesicular systems that facilitate enzyme immobilization.
- It examines the thermodynamics involved in the immobilization of specific enzymes, like laminarinase and chitinase, within liposomes.
- These systems offer protection for enzymes against environmental damage while enabling precise release, making them useful for applications like controlling plant-pathogenic fungi.
Aim: To reveal the molecular mechanism of anti-angiogenic activity of semisynthetic triterpenoid CDDO-Im.
Materials And Methods: Using re-analysis of cDNA microarray data of CDDO-Im-treated human vascular endothelial cells (HUVECs) (GSE71622), functional annotation of revealed differentially expressed genes (DEGs) and analysis of their co-expression, the key processes induced by CDDO-Im in HUVECs were identified. Venn diagram analysis was further performed to reveal the common DEGs, i.
