Specnuezhenide: Comprehensive review of pharmacology, pharmacokinetics and ethnomedicinal uses.

Background: Specnuezhenide (SPN) is a bioactive iridoid terpenoid compound mainly found in Ligustri Lucidi Fructus (LLF), that has a broad spectrum of pharmacological effects, including anti-neoplastic, hepatoprotective, anti-aging, anti-inflammatory, immune-modulatory properties.

Purpose: The present review provides a comprehensive summary of natural medicinal plants, traditional Chinese medicine compounds containing SPN, and their corresponding pharmacological mechanisms.

Methods: Using several globally recognized databases such as Web of Science, Google Scholar, PubMed, ScienceDirect, Wiley, ACS, Springer, and CNKI until December 2024, A comprehensive literature search and analysis was carried out with the keywords "Specnuezhenide", " Pharmacology ", "Pharmacokinetics" and " Chinese herbal compound".

Design, synthesis and in vitro evaluation of a novel "stealth" polymeric gene vector.

We report on the synthesis of a novel gene carrier that has low interaction with serum components, as well as low cytotoxicity. Cationic copolymers composing branched poly(ethylenimine) (PEI) grafted with hydrophilic poly(ethylene glycol) (PEG) and poly(l-lactic acid) (PLLA) or small-molecule oleoyl were synthesized and evaluated as novel gene carriers in this study. The copolymers were complexed with plasmid DNA and the resulting polyplexes were approximately 140nm in diameter and had a positive surface potential (zeta=+13.

ABA and BAB type triblock copolymers of PEG and PLA: a comparative study of drug release properties and "stealth" particle characteristics.

We synthesized two types of triblock copolymers containing PEG and PLA as controlled release carriers of hydrophobic drugs: these are the ABA type (PLA-PEG-PLA) and the BAB type (PEG-PLA-PEG). These polymers are amphiphilic and can form nanomicelles (40-200nm) in aqueous medium. On the surface of PLA-PEG-PLA (ABA) type nanomicelles, the PEG content was enhanced somewhat over the bulk amount; whereas in the PEG-PLA-PEG (BAB type), surface segregation was much higher.

Zn-OH2 and Zn-OH complexes with hydroborate-derived tripod ligands: a comprehensive study.

The complete array of those hydrotris(pyrazolyl/thioimidazolyl)borate ligands that were developed and used in the author's laboratories, with N3, N2S, NS2, and S3 donor sets, was scanned for their ability to form Zn-OH2 and Zn-OH complexes. The coordination motifs found were Zn-OH2, Zn-OH, Zn-OH-Zn, and Zn-O2H3-Zn. Of these, the well-established Zn-OH motif was complemented with novel species bearing N3, NS2, and S3 tripods.

Thiolate alkylation in tripod zinc complexes: a comparative kinetic study.

The biologically relevant alkylations of the thiolate ligands in tripod zinc thiolates by methyl iodide were studied kinetically. Five tripod ligands of the pyrazolyl/thioimidazolyl borate type were employed, offering N3, N2S, NS2, and S3 donor sets. For each of them, the ethyl-, benzyl-, phenyl-, and p-nitrophenylthiolate zinc complexes were investigated, yielding a total of 20 second-order rate constants.
