Abstract
Heart-type fatty-acid binding protein (FABP3) is an essential cytosolic lipid transport protein found in cardiomyocytes. FABP3 binds fatty acids (FAs) reversibly and with high affinity. Acylcarnitines (ACs) are an esterified form of FAs that play an important role in cellular energy metabolism. However, an increased concentration of ACs can exert detrimental effects on cardiac mitochondria and lead to severe cardiac damage. In the present study, we evaluated the ability of FABP3 to bind long-chain ACs (LCACs) and protect cells from their harmful effects. We characterized the novel binding mechanism between FABP3 and LCACs by a cytotoxicity assay, nuclear magnetic resonance, and isothermal titration calorimetry. Our data demonstrate that FABP3 is capable of binding both FAs and LCACs as well as decreasing the cytotoxicity of LCACs. Our findings reveal that LCACs and FAs compete for the binding site of FABP3. Thus, the protective mechanism of FABP3 is found to be concentration dependent.

Abstract
ε-Trimethyllysine dioxygenase (TMLD) is a non-heme Fe(II) and α-ketoglutarate dependent oxygenase that catalyzes the stereospecific hydroxylation of ε-trimethyl-l-lysine (TML) to β-hydroxy-TML during the first step of l-carnitine biosynthesis. Targeting TMLD with inhibitors is a viable strategy for the treatment of cardiovascular diseases. Herein, we report a methodology for isothermal titration calorimetry analysis of TMLD substrate analogue binding to the enzyme. Despite the high structural similarity of the tested compounds, two different binding mechanisms (enthalpy- and entropy-driven) were observed, giving insight into the ligand (substrate) selectivity of TMLD. We demonstrate that the method allows distinguishing a natural substrate-like binding mode, which correlates with the ability of the compounds to serve as substrates in the TMLD catalytic reaction.

Abstract
AbstractThe facile synthesis of highly functionalized building blocks with potential biological activity is of great interest to medicinal chemistry. The benzoxepinone core structures commonly exhibit biological activity. Thus, a short and efficient synthetic route towards benzoxepine containing scaffold, which enables late stage modification was developed. Namely, base-free catalytic Wittig reactions enabled the synthesis of bromobenzoxepinones from readily available starting materials. Subsequent, Suzuki–Miyaura and Stille reactions proved to be suitable methods to access a variety of benzoxepinone diaryl derivatives by late stage modification in only three steps. This three-step reaction sequence is suitable for high throughput applications and gives facile access to highly complex molecular structures, which are suitable for further functionalization. The antiproliferative properties of selected arylbenzoxepinones were tested in vitro on monolayer tumor cell line A549. Notably, in this initial screening, these compounds were found to be active in the micromolar range.
