Compounds based on Adamantyl-substituted Amino Acids and Peptides as Potential Antiviral Drugs Acting as Viroporin Inhibitors

Current Pharmaceutical Design, Journal Year: 2024, Volume and Issue: 30(12), P. 912 - 920

Published: March 14, 2024

The discussion has revolved around the derivatives of amino acids and peptides containing carbocycles their potential antiviral activity in vitro against influenza A, hepatitis C viruses, coronavirus. Studies conducted on cell cultures reveal that aminoadamantane acid exhibit capacity to hinder replication viruses viroporins. Furthermore, certain compounds demonstrate potent virucidal with respect A/H5N1 virus particles. A conceptual framework for viroporin inhibitors been introduced, incorporating carbocyclic motifs as membranotropic carriers structure, alongside a functional segment comprised peptides. These components correspond interaction inner surface channel's pore or another target protein.

16-Vertex oblato–hypho-titanaborane [(Cp*Ti)₂B₁₄H₁₈]

Chemical Communications, Journal Year: 2023, Volume and Issue: 59(78), P. 11676 - 11679

Published: Jan. 1, 2023

Although Lipscomb predicted in 1977 that supra-icosahedral boron clusters would be viable, their synthesis has been impeded by the unavailability of appropriate synthetic methodologies. Herein, we report first examples open 16-vertex oblato-hypho-titanaborane [(Cp*Ti)2B14H17R] (1: R = H; 2: Me) having a non-Wadean 19-skeletal-electron-pair count. Interestingly, these show six-membered [Ti2B4] face, which could lead to closo-19-vertex clusters.

Composites and Materials Prepared from Boron Cluster Anions and Carboranes

Materials, Journal Year: 2023, Volume and Issue: 16(18), P. 6099 - 6099

Published: Sept. 6, 2023

Here, we present composites and materials that can be prepared starting with boron hydride cluster compounds (decaborane, decahydro-closo-decaborate dodecahydro-closo-dodecaborate anions carboranes). Recent examples of their utilization as protective coatings including using them to synthesize carbide, nitride, metal borides, metal-containing composites, neutron shielding are discussed. The data generalized demonstrate the versatile application based on carboranes in various fields.

Gold(III) Complexation in the Presence of the Macropolyhedral Hydridoborate Cluster [B20H18]2−

Inorganics, Journal Year: 2022, Volume and Issue: 10(7), P. 99 - 99

Published: July 10, 2022

Gold(III) complexation with the octadecahydrido-eicosaborate anion [B20H18]2− was studied for first time. It found that when gold(III) complexes [Au(L)Cl2]BF4 (L = bipy, phen) reacted [B20H18]2−, [Au(L)Cl2]2[B20H18] were isolated. The compounds consisted of a cationic complex [Au(L)Cl2]+ and hydridoborate cluster as counterion. X-ray diffraction studies revealed weak B–H...Au interactions both compounds. Note more reactive anions [BnHn]2− (n 10, 12) in similar reactions resulted gold mirror reactions.
