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,

Biosynthetically‐Inspired Oxidative Cleavage Platform Enables Rapid Access to Diverse and Architecturally Complex Chemotypes From Indole Alkaloids

open access: yesChemistryEurope, Volume 4, Issue 4, April 2026.
We report a biosynthesis‐inspired ring distortion approach that involves oxidative ring cleavage, ring rearrangement, and ring expansion reactions from a diverse collection of indole alkaloids and derivatives. This chemical synthesis approach led to the synthesis of >25 distinct chemotypes from 14 indole alkaloids.

Engineering Lipid Nanoparticles for Precision RNA Delivery: Design Principles, Targeting Strategies, and Clinical Prospects

open access: yesCancer Nexus, Volume 2, Issue 2, April 2026.
ABSTRACT Lipid nanoparticles (LNPs) represent the most clinically advanced platform for RNA delivery and have enabled major breakthroughs in vaccines and gene therapies. However, their broader application is still limited by inefficient extrahepatic delivery, immunogenicity, and insufficient control over tissue‐ and cell‐specific targeting. This review

Identification of Metabolites of the Dietary Supplement Ingredient 5α‐Hydroxy‐Laxogenin

open access: yesDrug Testing and Analysis, Volume 18, Issue 4, Page 483-489, April 2026.
The biotransformation of the dietary supplement ingredient 5α‐hydroxy‐laxogenin was investigated using human HepG2 cells, the rat and in silico using the online software Next‐gen E‐Resource for Drug Discovery (NERDD). We identified five metabolites generated by the human HepG2 cells of which three and an additional mono‐hydroxylated metabolite were ...

A Click Approach to Novel D-Ring-Substituted 16α-Triazolylestrone Derivatives and Characterization of Their Antiproliferative Properties [PDF]

open access: yes, 2015
A simple and efficient synthesis of novel, D-ring substituted estrone derivatives containing a 16α-triazolyl moiety is described. Two epimeric azido alcohols (16α-azido-17α-hydroxy and 16α-azido-17β-hydroxy) of estra-1,3,5(10)-triene-3-methyl ether were ...

Identification of Blood Pressure‐Associated Metabolites by Integrating Metabolomic and Genetic Analysis

open access: yesMedComm, Volume 7, Issue 4, April 2026.
This study identified 10 potential causality between metabolites and blood pressure and found potential genetic regulators of two metabolites. Multiomics integration revealed that a genetic variant near the omega‐3 metabolism genes (FADS1/FADS2) may influence blood pressure regulation by modulating prostaglandin E3 levels.
