Energetic and topological approach for characterization of supramolecular clusters in organic crystals

In this work, an approach is proposed for understanding the crystal arrangements of organic compounds. The crystals are studied taking into account the stabilization energy and the topological properties like contact surfaces of a molecule (M1) due to the presence of neighboring Mn (cluster). The molecular system models chosen were five heterocycles and one beta-enaminone. The cluster of compounds had a Molecular Coordination Number (MCN) of 14, except for one compound that had an MCN of 16. Our study showed that intermolecular interactions can be divided into four main types: type I, with large energy values and a small contact surface; type II, involving a large value for both the energy and the contact surface; type III, with small and medium energy values, and a medium-sized contact surface; and type IV, with small energy values and a relatively large contact surface. Additionally, from this approach we show that only from the supramolecular cluster is it possible to observe the participation of the topological component during the formation of the crystal. This is demonstrated by the fact that the fragility of the electrostatic interaction between M1 and one Mn in the same plane is compensated by a strong interaction of M1 with a molecule in another plane.

Discovery of anilinopyrimidine-based naphthamide derivatives as potent VEGFR-2 inhibitors

Vascular endothelial growth factor receptor-2 (VEGFR-2) plays an important role in tumor angiogenesis, and inhibition of the VEGFR-2 signaling pathway has emerged as an attractive strategy for the treatment of cancer. Herein, we describe the design, synthesis, and biological evaluation of anilinopyrimidine-based naphthamide derivatives as potent VEGFR-2 inhibitors. Among the new derivatives, compound 3k exhibited high VEGFR-2 inhibitory potency in both enzymatic and VEGF-induced HUVEC cellular proliferation assays (IC50 = 0.5 and 9.8 nM, respectively). Kinase selectivity profiling revealed that 3k was a highly selective VEGFR-2 inhibitor. Moreover, 3k effectively inhibited angiogenesis in HUVEC tube formation assay.

Determination and toxicity evaluation of the generated products in sulfamethoxazole degradation by UV/CoFe2O4/TiO2

The photodegradation of sulfamethoxazole (SMX) under UV radiation with a recyclable catalyst CoFe2O4/TiO2 was examined. The reaction mechanism during the treatment was determined. The toxicity of the degradation intermediates to aquatic organisms, including the green alga Chlorella vulgaris and the brine shrimp Artemia salina was investigated. SMX was completely removed and about 50% TOC was degraded in 5 h. Sixteen intermediates were detected, from which four of them were reported for the first time in this study. Four main decay pathways, i.e., hydroxylation, cleavage of SN bond, nitration of amino group, and isomerization were proposed. About 45% of the total mass sulfur source transformed to sulfate ion, and around 25%, 1%, and 0.25% of the total nitrogen transformed to ammonium, nitrogen, and nitrite ions. The toxicity of the treated solution was significantly reduced compared to that of the parent compound SMX. A variation of the algae growth was observed, which was due to the combination of generation of toxic intermediates (i.e., sulfanilamide) and the release of inorganic substances and carbon source as additional nutrients. The adverse effect on the clearance rate of the brine shrimp was also observed, but it can be eliminated if longer degradation time is used.

Bispidine as a privileged scaffold

The diazabicyclic molecule bispidine named by the chemist Carl Mannich in 1930, is a naturally occurring scaffold with interesting features. Bispidine can form different conformers, has high basicity, can attack dichloromethane, has metal ion coordination properties and interacts with nicotinic acetylcholine receptors. In this review we will discuss important properties, synthetic pathways and biological activities of bispidine and some derivatives. Bispidine can function as a scaffold for compounds with very diverse biological activities, e.g. interacting with ion channels, G-protein coupled receptors, and enzymes, and is even used for the development of new in vivo radiotracers.
