Derivatives of grindelic acid: from a non-active natural diterpene to synthetic antitumor derivatives [PDF]

open access: yes, 2013
Using several reactions that include homologations and asymmetric epoxidations as well as Ugi and Huisgen couplings, we generated a small focused library of new derivatives from the labdane-type diterpene grindelic acid. These compounds were evaluated as

Cardenolide‐Engineered Extracellular Vesicles Augment Drug Uptake and Cytotoxicity in Non‐small Cell Lung Cancer Cells

open access: yesSmall Methods, EarlyView.
Cardenolide‐functionalized extracellular vesicles enable targeted delivery of the chemotherapeutic doxorubicin to A549 lung cancer cells by binding Na+/K+‐ATPase, which is overexpressed in these cells. Surface‐modified, drug‐loaded EVs exhibit enhanced cytotoxicity compared to unmodified EVs and free drug, suggesting this system may lower the effective

Ligand synthesis catalyst and complex metal ion: multicomponent synthesis of 1,3-bis(4-phenyl-[1,2,3]triazol-1-yl)-propan-2-ol copper(i) complex and application in copper-catalyzed alkyne-azide cycloaddition [PDF]

open access: yes, 2016
A new bistriazole copper complex was synthesized by direct treatment of an alkyne, an azide, and CuI as copper salt through in situ ligand formation under a multicomponent reaction process. This complex was analyzed by XPS, TGA, DSC, and SEM techniques

Coordination Studies of a Triazole‐Substituted 3H‐1,2,4‐Diazaphosphole: CC and CN Bond Activation Induced by Cobalt(0) and Nickel(0) Complexes

open access: yesZeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 2, 5 February 2026.
Reactions of a triazole‐substituted 3H‐1,2,4‐diazaphosphole with electron‐rich cobalt and nickel complexes result in the selective cleavage of CC and CN bonds on the triazole, forming chelate complexes with the activated diazaphosphole ligand. The reactivity of the recently reported 3H‐1,2,4‐diazaphosphole 1 toward electron‐rich Ni and Co complexes ...

Development of mixed metal metal-organic polyhedra networks, colloids, and MOFs and their pharmacokinetic applications [PDF]

open access: yes, 2017
The coordination networking of discrete metal-organic polyhedra (MOPs) involving different ligands as well as metals is a challenging task due to the features of limited solubility and chemical stability of these polyhedra.
