New Methods of Analysis and Investigation of Terpenoid Indole Alkaloids

open access: yes, 2013
Abstract Terpenoid indole alkaloids are biologically active compounds that have been used as pharmaceuticals among others as anticancer, antimalarial, antihypertensive and hypoglycemic agents for more than 40 years. Many efforts have been focused on their extraction, isolation, separation and structural elucidation by means of different approaches ...

Mass Spectrometry Imaging Combined With Single‐Cell Transcriptional Profiling Reveals the Multidimensional Spatial Distributions and Biosynthetic Pathways of Medicinal Components in Andrographis paniculata

open access: yesPlant Biotechnology Journal, Volume 24, Issue 5, Page 2876-2890, May 2026.
ABSTRACT The synthesis and accumulation of active ingredients in medicinal plants are distributed in specific organs, tissues, and cell types, which are important for the exploitation of medicinal plants. However, the fine distribution of active ingredients is difficult to know. Here, the system of mass spectrometry imaging (MSI) integrated with single‐

Three Closely Related Spodoptera Species Similarly Affect Gene Expression and Phytohormone Levels but Differentially Induce Volatile Emissions in Maize

open access: yesPlant, Cell &Environment, Volume 49, Issue 5, Page 2394-2412, May 2026.
ABSTRACT Plants can perceive specific elicitors in the oral secretions (OS) of herbivorous insects and respond by increasing their defences. Whether plants can discriminate among similar herbivorous insect species and differentially modulate their defence responses against them is largely unknown.

Environmental stress induced biosynthesis of plant secondary metabolites- transcriptional regulation as a key

open access: yesCrop Design
Secondary metabolites represnt are diverse array of plant-synthesized compounds that, while not essential for growth and development, play crucial roles in plant defense against biotic and abiotic stresses, attracting pollinators and seed dispersers, and

Anticancer and antifungal compounds from Aspergillus, Penicillium and other filamentous fungi [PDF]

open access: yes, 2013
This review covers important anticancer and antifungal compounds reported from filamentous fungi and in particular from Aspergillus, Penicillium and Talaromyces. The taxonomy of these fungi is not trivial, so a focus of this review has been to report the

Tabernaemontana catharinensis: A Source of Indole Alkaloids With Potential Activity as Chemotherapeutic Agents

open access: yesChemistry &Biodiversity, Volume 23, Issue 4, April 2026.
ABSTRACT This study aimed to evaluate the antitumor activity of fractions rich in indole alkaloids extracted from the leaves of the species Tabernaemontana catharinensis. The chemical composition was analyzed using high‐resolution mass spectrometry (HRMS), which identified nine known indole alkaloids, including voacangine, voacangine hydroxyindolenine,

An atypical strictosidine synthase, OsSTRL2, plays key roles in anther development and pollen wall formation in rice

open access: yesScientific Reports, 2017
Strictosidine synthase (STR) plays an important role in the biosynthesis of terpenoid indole alkaloids (TIAs) and is expressed in a range of active meristematic tissues of higher plants.

Jasmonic Acid Effect on the Fatty Acid and Terpenoid Indole Alkaloid Accumulation in Cell Suspension Cultures of Catharanthus roseus

open access: yesMolecules, 2014
The stress response after jasmonic acid (JA) treatment was studied in cell suspension cultures of Catharanthus roseus. The effect of JA on the primary and secondary metabolism was based on changes in profiles of fatty acids (FA) and terpenoid indole ...
