Mycochemical Diversity and Therapeutic Potential of Hymenochaetoid Fungi from Central Asia: Regional and Global Perspectives

New Zealand Journal of Botany, Volume 64, Issue 1, March 2026.
Central Asia harbors a rich yet understudied assemblage of wood‐inhabiting Hymenochaetoid fungi. This review delivers the first comprehensive synthesis of 43 poroid species representing 18 genera documented across montane forests, steppes, and xeric habitats.

New fluorogenic probes for neutral and alkaline ceramidases

Journal of Lipid Research, 2019
New fluorogenic ceramidase substrates derived from the N-acyl modification of our previously reported probes (RBM14) are reported. While none of the new probes were superior to the known RBM14C12 as acid ceramidase substrates, the corresponding nervonic ...

Introducing the Cis‐2,3‐Bis(trifluoromethyl)cyclopropyl Chemotype: Late‐Stage Installation and Stereoelectronic Properties

ChemistryEurope, Volume 4, Issue 2, February 2026.
The cis‐2,3‐bis(trifluoromethyl)cyclopropyl chemotype is introduced. The steric demand of this motif is intermediate between that of the heptafluoroisopropyl and prefluorotertbutyl groups; yet, it induces significantly less lipophilicity than these due to its facial polarity.

Study of Umbelliferone Hydroxylation to Esculetin Catalyzed by Polyphenol Oxidase

Biological and Pharmaceutical Bulletin, 2013
We characterize umbelliferone, a derivative of 2,4-dihydroxycoumaric acid, as a substrate of polyphenol oxidase. This enzyme hydroxylates umbelliferone to esculetin, its o-diphenol, and then oxidizes it to o-quinone. The findings show that umbelliferone, an intermediate in one of the coumarin biosynthesis pathways, may be transformed into its o ...
