Biochem Biophys Res Commun 2024; 739:150968. [PMID: 39531908 DOI: 10.1016/j.bbrc.2024.150968] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2024] [Revised: 11/02/2024] [Accepted: 11/07/2024] [Indexed: 11/16/2024]
Abstract
Acute lung injury (ALI) caused by sepsis is one of the most common critical diseases, which is difficult to treat and has a high fatality rate. Koumine is one of the main active components of Gelsemium plants and has been confirmed to have potential for drug development; however, its therapeutic effects on ALI have not yet been studied. This study established ALI due to sepsis using cecal ligation and puncture (CLP) and assessed the therapeutic effects of koumine by measuring mouse survival rates, lung tissue pathological damage, inflammatory factors, and oxidative stress levels. Additionally, network pharmacology was utilized to explore the underlying mechanisms. The results showed that koumine inhibited the release of tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6) and interleukin-1β (IL-1β), thereby inhibiting inflammatory response, reducing lung injury score and lung wet to dry ratio. In addition, koumine reduced oxidative stress in mice by reducing myeloperoxidase (MPO) and malondialdehyde (MDA) and increasing superoxide dismutase (SOD) content. Network pharmacology analysis showed that 52 putative targets were relevant, and SLC6A4, HTR3A, JAK2 and JAK3 were the key targets. GO and KEGG pathway enrichment analysis showed that the related mechanisms involved neuroactive ligand-receptor interaction, calcium signaling pathway, serotonergic synapses, cholinergic synapses, etc. In summary, this study confirmed the potential therapeutic effect of koumine in sepsis induced ALI, suggesting its development prospect as a novel candidate drug for ALI, and providing data support.

Abstract
Aims: Five series of novel koumine-like compounds were designed, semi-synthesized and systematically evaluated for antitumor activities.Methods: All compounds were evaluated for antiproliferative activity against four human cancer cell lines, including HT-29, HCT-116, HCT-15 and Caco-2.Results: Most compounds exhibited much higher antiproliferation activities (IC50 <10 μM) than koumine. Two selected compounds A4 and C5 showed comparable antitumor effects to 5-FU in vivo, as well as better safety profiles. Further studies suggested that A4 and C5 could arrest HT-29 cell cycle in G2 phase and raise reactive oxygen species level, thus inducing cell apoptosis related to Erk MAPK and NF-κB signaling pathways inhibition.Conclusion: These results will greatly promote the druggability study of these koumine-like compounds.

Abstract
Background There is still controversy regarding the relationship between hypothyroidism and rheumatoid arthritis (RA), and there has been a dearth of studies on this association. The purpose of our study was to explore the shared genetic architecture between hypothyroidism and RA. Methods Using public genome-wide association studies summary statistics of hypothyroidism and RA, we explored shared genetics between hypothyroidism and RA using linkage disequilibrium score regression, ρ-HESS, Pleiotropic analysis under a composite null hypothesis (PLACO), colocalization analysis, Multi-Trait Analysis of GWAS (MTAG), and transcriptome-wide association study (TWAS), and investigated causal associations using Mendelian randomization (MR). Results We found a positive genetic association between hypothyroidism and RA, particularly in local genomic regions. Mendelian randomization analysis suggested a potential causal association of hypothyroidism with RA. Incorporating gene expression data, we observed that the genetic associations between hypothyroidism and RA were enriched in various tissues, including the spleen, lung, small intestine, adipose visceral, and blood. A comprehensive approach integrating PLACO, Bayesian colocalization analysis, MTAG, and TWAS, we successfully identified TYK2, IL2RA, and IRF5 as shared risk genes for both hypothyroidism and RA. Conclusions Our investigation unveiled a shared genetic architecture between these two diseases, providing novel insights into the underlying biological mechanisms and establishing a foundation for more effective interventions.

D-Optimal Design and Development of a Koumine-Loaded Microemulsion for Rheumatoid Arthritis Treatment: In vivo and in vitro Evaluation. Int J Nanomedicine 2023; 18:2973-2988. [PMID: 37304972 PMCID: PMC10255651 DOI: 10.2147/ijn.s406641] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2023] [Accepted: 05/15/2023] [Indexed: 06/13/2023] Open
Abstract
Introduction Koumine (KME) is the most abundant active ingredient separated from Gelsemium elegans Benth and exhibits a significant therapeutic effect on rheumatoid arthritis (RA). It is a lipophilic compound with poor aqueous solubility, and there is an urgent need to develop novel dosage forms of KME and promote its clinical application for the treatment of RA. The aim of this study was to design and develop KME-loaded microemulsions (KME-MEs) for the effective management of RA. Methods The composition of the microemulsion was selected by carrying out a solubility study and generating pseudoternary phase diagrams, and further optimized by D-Optimal design. The optimized KME-MEs was evaluated for particle size, viscosity, drug release, storage stability, cytotoxicity, cellular uptake, Caco-2 cell transport and everted gut sac investigations. In vivo fluorescence imaging and the therapeutic effects of KME and KME-MEs on collagen-induced arthritis (CIA) rats were also evaluated. Results The optimized microemulsion contained 8% oil, 32% Smix (surfactant/cosurfactant) and 60% water and was used for in vivo and in vitro studies. The optimal KME-MEs exhibited a small globule size of 18.5 ± 0.14 nm and good stability over 3 months, and the release kinetics followed a first-order model. These KME-MEs had no toxic effect on Caco-2 cells but were efficiently internalized into the cytoplasm. Compared to KME, the KME-MEs displayed significantly increased permeability and absorption in Caco-2 cell monolayer assay and ex vivo everted gut sac experiment. As expected, the KME-MEs attenuated the progression of RA in CIA rats and were more effective than free KME with a reduced frequency of administration. Conclusion The KME-MEs improved the solubility and therapeutic efficacy of KME by employing formulation technology. These results provide a promising vehicle for the oral delivery of KME to treat RA and have attractive potential for clinical translation.
