Isocyanate toughening of pCBT/organoclay nanocomposites with exfoliated structure and enhanced mechanical properties

open access: yeseXPRESS Polymer Letters, 2014
Cyclic butylene terephthalate (CBT®) is an interesting matrix material for the preparation of nanocomposites due to its very low, water-like melt viscosity which favours clay exfoliation. Nevertheless, polymerized CBT (pCBT) is inherently brittle.

A Sydnonimine‐based Click‐and‐Release Approach to Cyclic Products

open access: yesChemistry – A European Journal, EarlyView.
Macrocyclick‐and‐release: The combination of a chemoselective Cu‐catalyzed click‐and‐release reaction and pyrene tags allows efficient synthesis of macrocycles and easy isolation by simple filtration through graphitic material. Abstract Herein, we report a general, efficient, and practical methodology for the macrocyclization of compounds based on the ...

Strategy‐Level Prodrug Synthesis

open access: yesChemistry – A European Journal, Accepted Article.
Organic synthesis uniquely provides opportunities to access molecules that serve defined purposes. Medicinal chemistry illustrates this attribute well with prodrug design, whereby a drug undergoes a late‐stage conversion to a conditionally responsive active medicinal agent (AMA), being a notable example.

β‐Lactam Ylidenes: An Overlooked Class of N‐Heterocyclic Carbenes

open access: yesChemistry – A European Journal, EarlyView.
A highly modular synthetic approach toward four‐membered β‐lactam carbenes (BLCs) is presented. BLCs feature moderate σ‐donor and strong π‐acceptor character, leading to a pronounced ambiphilic reactivity which includes the formation of olefinic dimers as well as unprecedented N2‐bridged dimers, oxirane formation with acetone, and fragmentation to ...

Improved C5‐Amide Bioisosteres for Human Neuraminidase 1 Inhibitors Based on 2‐Deoxy‐2,3‐Didehydro‐N‐Acetyl Neuraminic Acid

open access: yesChemMedChem, EarlyView.
This article describes the development of improved NEU1 inhibitors based on the 2‐deoxy‐2,3‐didehydro‐N‐acetyl neuraminic acid scaffold. A series of candidate inhibitors are designed containing bioisosteres of the C5‐amide group and evaluated for activity against NEU1‐4 enzymes.

Novel para‐phenylenediamine‐based derivatives as Receptor Tyrosine Kinase‐like Orphan Receptor 1 (ROR1) Inhibitors: An in vitro preliminary characterization

open access: yesChemMedChem, Accepted Article.
ROR1 kinase is an underexplored promising target for the development of novel anticancer drugs, being strongly expressed in several cancer cell lines, but poorly in non‐tumor cells. This property, together with the scarce number of molecules effective against ROR1, led us to design and develop a research program aimed to the discovery of new chemical ...
