Abstract:
A series of guanidine cations and azole anions were designed for use as energetic salts. Their geometrical structures were optimized by the density functional theory (DFT) method. The counter ions were matched by the similar magnitude of the electron affinity (EA) of the cation and the ionization potential (IP) of the anion. The densities, heats of formation, detonation parameters, and impact sensitivity were predicted. The incorporation of guanidine cations and diazole anions are favorable to form thermal stable salts except cation A1. The diaminoguanidine cation has greater impact on the den

Abstract:
The N-terminal portion of the octapeptide angiotensin II (DRVYIHPF; AngII), a vasopressor peptide that favorably binds to, and activates, AngII type 1 receptor (AT1R), has an important role in maintaining bioactive conformation. It involves all three charged groups, namely (i) the N-terminal amino group cation, (ii) the Asp sidechain anion and (iii) the Arg guanidino cation. Neutralization of any one of these three charged groups results in a substantial reduction (&lt;5%) in bioactivity, implicating a specialized function for this cluster. In contrast, angiotensin A (ARVYIHPF; AngA) has reduc

Abstract:
Angiotensin II (Ang II) may contain a charge relay system (CRS) involving Tyr/His/carboxylate, which creates a tyrosinate anion for receptor activation. Energy calculations were carried out to determine the preferred geometry for the CRS in the presence and absence of the Arg guanidino group occupying position 2 of Ang II. These findings suggest that Tyr is preferred over His for bearing the negative charge and that the CRS is stabilized by the guanidino group. Recent crystallography studies provided details of the binding of nonpeptide angiotensin receptor blockers (ARBs) to the Ang II type 1

Abstract:
Complex coacervation is an emerging liquid/liquid phase separation (LLPS) phenomenon that behaves as a membrane-less organelle in living cells. Yet while one of the critical factors for complex coacervation is temperature, little analysis and research has been devoted to the temperature effect on complex coacervation. Here, we performed a complex coacervation of cationic protamine and multivalent anions (citrate and tripolyphosphate (TPP)). Both mixtures (i.e., protamine/citrate and protamine/TPP) underwent coacervation in an aqueous solution, while a mixture of protamine and sodium chloride d

Abstract:
The aim of the project was to extend the field of molecular recognition of anions and cations of biochemical, medical, chemical and environmental importance. This was achieved by the use of a number of novel receptor molecules that are designed to bind anionic and cationic guests. The binding of the guest anions and cations was probed by various electrochemical, spectrochemical and IH NMR spectroscopy techniques. The receptor molecules studied included (i) ruthenium(II) trisbipyridyl complexes of acyclic, calix[4]arene and cyclic 2,2'-bipyridine ligands, (ii) the macrocycle Nphenylaza- 15-crow

Abstract:
The N-methyl-D-aspartate (NMDA) receptors are highly regulated ligand-gated ion channels, which are affected by many substrates. Overactivation of the NMDA receptor can lead to hyperexcitability and a number of neurotoxic effects and neurological diseases. Agmatine has been demonstrated to act allosterically as an inhibitory modulator at the polyamine recognition sites of the NMDA receptor complex. The present study synthesized and evaluated a library of agmatine analogs for their ability to displace tritiated MK-801 from NMDARs in P2 membrane preparations from rat brains at ligand concentrati

Investigation on a series of hydrogen-bonded networks constructed with N-heteroaryl acids is described in Section 3.4. In this section, we focused on the connection modes within the heteroaryl dimer. The study of co-crystals and inclusion compounds based on 2-thiobarbituric acid (TBA) or trithiocyanuric acid (TCA) indicated that the dimer of TBA is present in all three crystals in the forms of ribbon, tetramer or separated dimer. In the case of 5-nitrobarbiturate, its dimer occurs in two ammonium salts and in three of its four thiourea complexes, but is absent in all three urea complexes.<br>

Abstract The past decade has witnessed an upsurge of interest in molecular recognition processes. Whereas the syntheses of new host structures initially stood to the fore, more recent studies have concentrated on the selectivity of supramolecular structures, on hydrophobic interactions, base pairing due to hydrogen bridges, hydrogen bridging in the interior of molecular niches, complexation of anions, and highly selective and extremely efficient cation complexation. Whilst simple cation complexation by use of crown compounds, cryptands, and podands is understood quite well at the present time,

DM affects almost 600 million people globally with an annual cost of around three trillion US dollars. These data indicate that DM is a global health burden that warrants attention.
