Cell type matters : competence for alkaloid metabolism differs in two seed-derived cell strains of Catharanthus roseus [PDF]

open access: yes, 2023
Since the discovery of the anticancer drugs vinblastine and vincristine, Catharanthus roseus has been intensively studied for biosynthesis of several terpene indole alkaloids (TIAs).

Photochemical Approaches to Complex Chemotypes: Applications in Natural Product Synthesis. [PDF]

open access: yes, 2016
The use of photochemical transformations is a powerful strategy that allows for the formation of a high degree of molecular complexity from relatively simple building blocks in a single step. A central feature of all light-promoted transformations is the

Bisleuconothine A protects periodontal tissue via the regulation of RANKL expression and infiltration of inflammatory cells [PDF]

open access: yes, 2020
Purpose: To investigate the protective effect of bisleuconothine A on periodontal tissue in rats and the mechanism involved. Methods: Adult male Sprague Dawley rats (n = 32) weighing 180 - 200 g (mean weight, 190 ± 10 g) were randomly assigned to four ...

C. elegans-based screen identifies lysosome-damaging alkaloids that induce STAT3-dependent lysosomal cell death

open access: yesProtein & Cell, 2018
Lysosomes are degradation and signaling centers within the cell, and their dysfunction impairs a wide variety of cellular processes. To understand the cellular effect of lysosome damage, we screened natural small-molecule compounds that induce lysosomal ...

Synthetic Analogues of the Snail Toxin 6-Bromo-2-mercaptotryptamine Dimer (BrMT) Reveal That Lipid Bilayer Perturbation Does Not Underlie Its Modulation of Voltage-Gated Potassium Channels [PDF]

open access: yes, 2018
Drugs do not act solely by canonical ligand–receptor binding interactions. Amphiphilic drugs partition into membranes, thereby perturbing bulk lipid bilayer properties and possibly altering the function of membrane proteins.

Attempted Synthesis of Vinca Alkaloids Condensed with Three-Membered Rings

open access: yesMolecules, 2018
Our successful work for the synthesis of cyclopropanated vinblastine and its derivatives by the Simmons–Smith reaction was followed to build up further three-membered rings into the 14,15-position of the vindoline part of the dimer alkaloid ...
