Riboflavin Interactions with Oxygen—A Survey from the Photochemical Perspective
Authors: Insińska‐Rak Małgorzata , Sikorski Marek 
Published: October 2014

AbstractIn this short review we provide some insights to the main processes that riboflavin is involved in upon absorption of a photon. We describe riboflavin properties in its interactions with oxygen, comparing them to the properties of some other singlet oxygen sensitizers. Data are provided on riboflavin photosensitizing properties in vivo and in vitro, and its properties as an endogenous singlet oxygen sensitizer are discussed. We additionally report flavin catalytic role in organic synthesis and photochemical reactivity in solutions of riboflavin and some of its derivatives.
Cathepsin‐B Induced Controlled Release from Peptide‐Capped Mesoporous Silica Nanoparticles

Published: October 2014

AbstractNew capped silica mesoporous nanoparticles for intracellular controlled cargo release within cathepsin B expressing cells are described. Nanometric mesoporous MCM‐41 supports loaded with safranin O (S1‐P) or doxorubicin (S2‐P) containing a molecular gate based on a cathepsin B target peptidic sequence were synthesized. Solids were designed to show “zero delivery” and to display cargo release in the presence of cathepsin B enzyme, which selectively hydrolyzed in vitro the capping peptide sequence. Controlled delivery in HeLa, MEFs WT, and MEFs lacking cathepsin B cell lines were also tested. Release of safranin O and doxorubicin in these cells took place when cathepsin B was active or present. Cells treated with S2‐P showed a fall in cell viability due to nanoparticles internalization, cathepsin B hydrolysis of the capping peptide, and cytotoxic agent delivery, proving the possible use of these nanodevices as new therapeutic tools for cancer treatment.
Design of Enzymatically Cleavable Prodrugs of a Potent Platinum‐Containing Anticancer Agent
Authors: Ding Song , Pickard Amanda J. , Kucera Gregory L. , Bierbach Ulrich 
Published: October 2014

AbstractUsing a versatile synthetic approach, a new class of potential ester prodrugs of highly potent, but systemically too toxic, platinum–acridine anticancer agents was generated. The new hybrids contain a hydroxyl group, which has been masked with a cleavable lipophilic acyl moiety. Both butanoic (butyric) and bulkier 2‐propanepentanoic (valproic) esters were introduced. The goals of this design were to improve the drug‐like properties (e.g., logD) and to reduce the systemic toxicity of the pharmacophore. Two distinct pathways by which the target compounds undergo effective ester hydrolysis, the proposed activating step, have been confirmed: platinum‐assisted, self‐immolative ester cleavage in a low‐chloride environment (LC‐ESMS, NMR spectroscopy) and enzymatic cleavage by human carboxylesterase‐2 (hCES‐2) (LC‐ESMS). The valproic acid ester derivatives are the first example of a metal‐containing agent cleavable by the prodrug‐converting enzyme. They show excellent chemical stability and reduced systemic toxicity. Preliminary results from screening in lung adenocarcinoma cell lines (A549, NCI‐H1435) suggest that the mechanism of the valproic esters may involve intracellular deesterification.
