Published: April 2018

A new ent-abietane diterpernoid, named ebracteolata D (1), along with 11 known analogues, was isolated from the roots of Euphorbia ebracteolata Hayata. The structure of 1 was elucidated on the basis of spectroscopic analysis and molecular modeling. Cytotoxicity of compounds 1-12 was evaluated as well as the effect on the NF-κB pathway. Among them, compound 12, jolkinolide B, displayed broad inhibitory effects against proliferation of tumor cell lines. Mechanistic studies indicated that the compound 12 can inhibit TNF-α induced NF-κB activation, thereby inducing tumor cell apoptosis.

WRKY transcription factors (TFs) play pivotal roles in regulating plant nutrient uptake, particularly phosphate (Pi) acquisition, and biosynthesis of secondary metabolites. Euphorbia lathyris, a significant medicinal plant with diverse pharmacological activities, lacks a systematic analysis of WRKY members and their functional roles. In this study, 58 ElWRKY genes were identified in the E.

The widespread use of nanoparticles raises substantial environmental, health, and safety issues. The specific mechanisms by which they impact plants and animals, as well as the entire scope of their possible impact, are still unknown. The current work investigates the impact of varying CuO NPs concentrations on phytotoxicity, cytotoxicity, genotoxicity, and antioxidant activity.

Article Synopsis
  • * Liposomes were created with a specific ratio of components and attached to a PSA antibody, successfully encapsulating anticancer drugs (doxorubicin and docetaxel) alongside plant extracts.
  • * The study found that heating the liposomes to 39-40 °C activated them, releasing their contents and effectively inhibiting the growth of prostate cancer cell lines (LNCap and DU145) when compared to non-heated conditions.

Based on transport inhibition and genome-wide analysis, 123 ABC transporters of Euphorbia lathyris were identified, and it was found that the PDR family members ElABCG39 mediated ingenol efflux. Identification of ingenol biosynthetic enzymes and transporters in plant is fundamental to realize its biosynthesis in chassis cells. At present, several key enzymes of the ingenol biosynthesis pathway have been identified, while the mechanisms governing the accumulation or transport of ingenol to distinct plant tissue compartments remain elusive.
