T220L

Reported in fluconazole-resistant isolates; typically modest–moderate increases (e.g., ~4–16-fold) depending on background and co-occurring mechanisms.

Moderate increases for voriconazole in some isolates (2–8-fold).

T220L reported in multiple clinical collections; often found in isolates where ERG11 substitutions explain a portion of resistance but efflux/regulatory changes also contribute.

Triazolopyrimidyl - The Structural and Physico-Chemical Properties of these Compounds - Non-Elaborate Posts - Post 9

    The inherent aromaticity of triazolopyrimidyl scaffolds provides a stable backbone for derivatization, however aromaticity is not monolithic.  Substituents can perturb resonance stabilization, influencing both chemical reactivity and biological affinity. Balancing substitution without disrupting the delicate aromatic equilibrium is a continual challenge for chemists optimizing scaffold activity. Tautomerism represents a further dimension of complexity.  Triazolopyrimidyl compounds can exist in multiple tautomeric forms depending on protonation state and solvent environment. These equilibria affect binding interactions, metabolic transformations, and physicochemical readouts. Analytical techniques such as variable-temperature NMR provide crucial windows into tautomeric dynamics.

Research unveils Rubik's cube-like Heusler materials with potential for thermoelectric applications

Image
            Researchers from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences have designed Slater-Pauling (S-P) Heusler materials with a unique structure resembling a Rubik's cube. These materials exhibit semiconductor-like properties and have potential in thermoelectric applications.  In traditional semiconductor Heusler alloys, the number of valence electrons follows a specific rule. However, these S-P Heusler compounds defy this rule while still displaying semiconductor behavior.  In this study, the team focused on two Heusler systems: Ti-Fe-Sb and M-Co-Sn (M = Ti, Zr, Hf). Within these two systems, they predicted the thermodynamically stable TiFe 1.5 Sb and MCo 1.33 Sn S-P semiconductors.  he researchers explained the unique properties of these compounds. In addition to the known half-Heusler (HH) and full-Heusler (FH) local geometries, these S-P structures contain defective-HH (DH) and defective-FH (...
