RESUMEN

Rheumatoid arthritis(RA), as a chronic autoimmune disease, has a high incidence and disability rate, causing significant suffering to patients. Due to its complex pathogenesis, it has not been fully elucidated to date, and its treatment remains a challenging problem in the medical field. Although western medicine treatment options have certain efficacy, they require prolonged use and are expensive. Additionally, they carry risks of multiple infections and adverse reactions like malignancies. The Chinese herbal medicine Rhododendron molle is commonly used in folk medicine for its properties of dispelling wind, removing dampness, calming nerves, and alleviating pain in the treatment of diseases like rheumatic bone diseases. In recent years, modern clinical and pharmacological studies have shown that the diterpenoids in R. molle are effective components, exhibiting immune-regulatory, anti-inflammatory, and analgesic effects. This makes it a promising candidate for treating RA with a broad range of potential applications. However, R. molle has certain toxic properties that hinder its clinical application and lead to the wastage of its resources. This study reviewed recent research progress on the mechanism of R. molle in preventing and treating RA, focusing on its chemical components, anti-inflammatory and analgesic properties and summarized the adverse reactions associated with R. molle, aiming to offer new ideas for finding natural remedies for RA and methods to reduce toxicity while enhancing the effectiveness of R. molle. The study seeks to clarify the safety and efficacy of R. molle and its extracts, providing a theoretical basis for its application prospects and further promoting the development and utilization of R. molle resources.

RESUMEN

Natural plant-derived diterpenoids are a class of compounds with diverse structures and functions. These compounds are widely used in pharmaceuticals, cosmetics and food additives industries because of their pharmacological properties such as anticancer, anti-inflammatory and antibacterial activities. In recent years, with the gradual discovery of functional genes in the biosynthetic pathway of plant-derived diterpenoids and the development of synthetic biotechnology, great efforts have been made to construct a variety of diterpenoid microbial cell factories through metabolic engineering and synthetic biology, resulting in gram-level production of many compounds. This article summarizes the construction of plant-derived diterpenoid microbial cell factories through synthetic biotechnology, followed by introducing the metabolic engineering strategies applied to improve plant-derived diterpenoids production, with the aim to provide a reference for the construction of high-yield plant-derived diterpenoid microbial cell factories and the industrial production of diterpenoids.

RESUMEN

Aim To study the anti-inflammatory activ¬ity of diterpenes from Tripterygium wilfordii on lipopo- lysaccharide ( LPS)-induced macrophage and its mech¬anism. Methods MTT assay was used to detect the cytotoxicity of compounds. The Griess method was used to detect the NO on LPS-induced RAW264. 7 cells. ELISA was applied to determine the contents of inter- leukin 6 (IL-6) , tumor necrosis factor a ( TNF-a ) , interleukin lp (IL-lfj) and interleukin 18 (IL-18) in cell culture supernatant. Western blot was used to de¬tect IkBcx, .INK, ERK, p38, STAT3 and their phos-phorylation in LPS-induced RAW264.7, as well as the effect on COX-2, iNOS, NLRP3, caspase-1 , cleaved- caspase-1. Flow cytometry was employed to detect the effects of compounds on the phagocytosis of RAW 264. 7 cells. Results Hypoglicin II (1) and ent-pimara-8 (14) , 15-diene-19-ol (6) , two diterpenoid compounds from Tripterygium wilfordii could effectively inhibit the expression of inflammatory mediators ( COX-2 and iN- OS) and inflammatory cytokines (IL-6, IL-lp, IL- 18) in LPS-induced RAW264. 7 cells. Further re¬search found that the phosphorylation of IkBcx , JNK, ERK, P38, STAT3 and NLRP3 was all inhibited; however, there was no significant effect on the expres¬sion of IkBcx, JNK, ERK, P38 and STAT3. At the same time, they also inhibited the phagocytosis of mac-rophages. Conclusions The anti-inflammatory mecha¬nism of Tripterygium wilfordii diterpenoids 1 and 6 might be through inhibiting the production of NLRP3 inflammatory bodies, inflammatory mediators (COX-2 and iNOS) and inflammatory cytokines (IL-6, IL-lp and IL-18) , which is closely related to inhibiting the activation of MAPK, NF-kB and STAT3 pathway.

RESUMEN

Plant-derived labdane-related diterpenoids (LRDs) represent a large group of terpenoids. LRDs possess either a labdane-type bicyclic core structure or more complex ring systems derived from labdane-type skeletons, such as abietane, pimarane, kaurane, etc. Due to their various pharmaceutical activities and unique properties, many of LRDs have been widely used in pharmaceutical, food and perfume industries. Biosynthesis of various LRDs has been extensively studied, leading to characterization of a large number of new biosynthetic enzymes. The biosynthetic pathways of important LRDs and the relevant enzymes (especially diterpene synthases and cytochrome P450 enzymes) were summarized in this review.

RESUMEN

Aim To investigate the effect of JYD01, an ent-kaurane diterpenoid analog, on detaching hexokinase II (HK II) from mitochondria, and discuss the underlying mechanism of anti-gastric cancer cell proliferation. Methods MTT assay was performed to measure the effect of JYD01 on the growth capacity of human gastric cancer cell lines MGC-803 and BGC-823. The glycolysis of MGC-803 cells in response to JYD01 was analyzed using a Seahorse XFp extracellular flux analyzer by real-time measurements of the extracellular acidification rate (ECAR, indicative of glycolysis). The effect of JYD01 in mitochondrial membrane potential (MMP) and apoptosis was observed by a fluorescence microscopy. The apoptotic rate and the quantitative analysis of MMP falling of cell lines treated with JYD01 were analyzed by flow cytometry. The proteins were determined by Western blot. Results JYD01 observably inhibited the growth of MGC-803 and BGC-823 cells in a dose-dependent manner. JYD01 induced a dose-dependent detachment of HK II from mitochondria of MGC-803 cells, effectively reduced glycolysis, and caused the drop of MMP leading to the release of cytochrome c. 1, 2 and 4 μmol · L
