Non-adsorbing small molecules as auxiliary dispersants for polycarboxylate superplasticizers

Assessment of the interaction of polycarboxylate superplasticizers in hydrated lime pastes modified with nanosilica or metakaolin as pozzolanic reactives

Two polycarboxylate ether copolymers were assessed as superplasticizers (SPs) for hydrated lime pastes modified with two reactive compounds, nanosilica (NS) and ceramic metakaolin (MK). Characterization of the molecular structure of the SPs by Size Exclusion Chromatography, XRD, FTIR and MALDI-TOF (Matrix Assisted Laser Desorption Ionization Time-of-Flight) mass spectrometry was performed. The ...

P122: Small Molecules as Chemical and Pharmacological Tools for Neuroinflammatory Diseases Treatment (with Emphasis on Multiple Sclerosis)

Multiple Sclerosis (MS) is a neuroinflammatory disease resulting in degeneration of the myelin sheaths and death of oligodendrocytes. So far, several strategies have been introduced to control the disease. Treatment with small molecules is one of the strategies that have recently attracted the attention in the scientific community. These molecules that target epigenetic and other cellular proce...

Design, Synthesis and Evaluation of Substituted Aryl-2-Nitrovinyl Derivatives as Small Molecules Proteasome Inhibitors

Based on the existing structure activity relationship for proteasome inhibitors, a number of substituted aryl-2-nitrovinyl derivatives have been synthesized as Michael acceptor and their cytotoxicity and proteasome inhibitory effects were evaluated on two cancer cell lines. Compound 2d exhibited IC50 values of 0.71 and 17.79 μM comparable to bortezomib against MCF-7 and PC-3, respectively. The ...
