The nitrogen mustard alkylating agent chlorambucil (CBL) is a critical component of chemotherapeutic regimens used in the treatment chronic lymphocytic leukemia. cancer cell-killing actions CBL are limited by glutathione (GSH) conjugation, process catalyzed GSH transferase hGSTA1-1 that triggers efflux from cells. In cell microenvironment, intracellular levels elevated to counterbalance oxidative stress generated due high glycolytic demand. As many drugs trigger death through mechanisms depend on reactive oxygen species (ROS), antioxidant capacity cells also represents barrier anticancer therapies. Here, we demonstrate heightened content can be exploited for cell-selective drug delivery. We successfully synthesized malononitrile conjugate terpyridine-based derivative

Brain tumors, particularly glioblastomas, represent the most complicated cancers to treat and manage due their highly invasive nature protective barriers of brain, including blood-brain barrier (BBB). The efficacy currently available treatments, viz., radiotherapy, chemotherapy, immunotherapy, are frequently limited by major side effects, drug resistance, restricted penetration into brain. Lipid nanoparticles (LNPs) have emerged as a promising targeted delivery system for brain tumors. nanocarriers gained tremendous attention tumor therapeutics multiple encapsulation abilities, controlled release, better biocompatibility, ability cross BBB. Herein, detailed analysis design, mechanisms, therapeutic benefits LNPs in treatment is discussed. Moreover, we also discuss safety issues clinical developments current future challenges. Further, focused on transformation therapy eliminating effects engineering overcome related biological barriers, which provide personalized, affordable, low-risk options.

Nanoparticles (NPs) are widely used in the pharmaceutical field to treat various human disorders. Among these, lipid-based NPs (LNPs), including solid lipid nanoparticles (SLN) and nanostructured carriers (NLC), favored for drug/bioactive delivery due their high stability, biocompatibility, encapsulation efficiency, sustained/controlled release. These properties make them particularly suitable as of compounds derived from plant sources.

The Blood-Brain Barrier (BBB) significantly impedes drug delivery to the central nervous system. Nanotechnology, especially surface-functionalized lipid nanoparticles, offers innovative approaches overcome this barrier. However, choosing an effective functionalization strategy is challenging due lack of detailed comparative analysis in current literature. Our systematic review examined various strategies and their impact on BBB permeability from 2041 identified articles, which 80 were included for data extraction. Peptides most common modification (18) followed by mixed (12) proteins (9), antibodies (7), other (8). Interestingly, 26 studies showed penetration with unmodified or modified nanoparticles using commonly applied such as PEGylation surfactant addition. Statistical across 42 correlation between higher vivo permeation improvements nanoparticle type, size, category. highest ratios found nanostructured carriers biomimetic systems, particle sizes under 150 nm, those applying strategies. interstudy heterogeneity we observed highlights importance adopting standardized evaluation protocols enhance comparability. aims provide a insight identify future research directions development more systems brain help improve treatment neurological psychiatric disorders tumours.
