Invasive fungal diseases (IFDs) comprise a growing healthcare burden, especially given the expanding population of immunocompromised hosts. Early diagnosis IFDs is required to optimise therapy with antifungals, in setting rising rates antifungal resistance. Molecular techniques including nucleic acid amplification tests and whole genome sequencing have potential offer utility overcoming limitations traditional phenotypic testing. However, standardisation methodology interpretations these assays an ongoing undertaking. The targeted

Abstract Echinocandins are a class of antifungal drugs that inhibit the activity β‐(1,3)‐glucan synthase complex, which synthesizes fungal cell wall β‐(1,3)‐glucan. Echinocandin resistance is linked to mutations in FKS gene, encodes catalytic subunit glucan complex. We present molecular‐docking‐based model provides insight into how echinocandins interact with target Fks protein: form ternary complex both and membrane lipids. used reductive dehydration alcohols generate dehydroxylated echinocandin derivatives evaluated their potency against panel Candida pathogens constructed by introducing resistance‐conferring gene. found removing hemiaminal alcohol, drives significant conformational alterations modified echinocandins, reduced efficacy. Conversely, eliminating benzylic alcohol enhanced up two orders magnitude, manner dependent upon mutation. Strains have developed either rezafungin, most recently clinically approved echinocandin, or its derivative RZF‐1, exhibit high rezafungin while demonstrating moderate RZF‐1. These findings provide valuable for combating through chemical modifications.

Amphotericin B has long been crucial for treating many serious infectious diseases, such as invasive fungal infections and visceral leishmaniasis, particularly patients who are immunocompromised, including those with advanced HIV infection.

Fungal effector proteins function at the interfaces of diverse interactions between fungi and their plant animal hosts, facilitating that are pathogenic or mutualistic. Recent advancements in protein structure prediction have significantly accelerated identification functional predictions these rapidly evolving proteins. This development enables scientists to generate testable hypotheses for validation using experimental approaches. Research frontiers biology include understanding pathways through which secreted translocated into host cells, roles manipulating microbiomes, contribution interacting with immunity. Comparative repertoires among different fungal-host can highlight unique adaptations, providing insights novel antifungal therapies biocontrol strategies.
