Bio‐Based Amino Acid Curing Additives: Mechanistic and Kinetic Effects in Epoxidized Soybean Oil Epoxy Thermosets

open access: yesJournal of Vinyl and Additive Technology, Volume 32, Issue 6, Page 1461-1474, November 2026.
The curing process of epoxidized soybean oil (ESO) is feasible through the incorporation of amino acids, generating materials with greater thermal stability and improved environmental friendliness. ABSTRACT In this study, the curing and thermal degradation kinetics of epoxidized soybean oil (ESO) were investigated using L‐aspartic acid (AA) and DL ...

Synthesis, Characterization, and In Vitro Evaluation of New Amino‐Alcohol Quinolines as Promising Antimycobacterial Agents

open access: yesChemMedChem, Volume 21, Issue 20, 28 October 2026.
Nontuberculous mycobacteria (NTM) mainly Mycobacterium avium complex (MAC), are emerging pathogens responsible for pulmonary infections. The efficacy of the standard treatment is therefore compromised by the emergence of intrinsic and acquired resistance in MAC.

Synthetic Strategies for the Construction of Cyclobutane‐Fused Heterocycles

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 40, 27 October 2026.
Cyclobutane‐fused heterocycles are important motifs commonly present in bioactive compounds, recognized for their rigid 3D structures that confer unique properties. However, synthesizing these compounds remains challenging. This review discusses current methods for their synthesis, such as photochemical, metal‐catalyzed, and Lewis acid‐mediated [2 + 2]
