Deciphering the biosynthetic pathways of lichen acids
New Phytologist, Volume 250, Issue 3, Page 1784-1799, May 2026.Summary Depsides and depsidones are polyketide‐derived lichen acids widely distributed in lichen thalli, yet the biosynthetic gene clusters (BGCs) responsible for their production remain poorly understood. To address this gap, we investigated the diversity and evolutionary relationships of polyketide BGCs in lichens.

Novel chiral molecular tweezer from (+)-usnic acid.
, 2009 International audienceA new chiral molecular tweezer was synthesized with (1R,2R)-1,2-diaminocyclohexane as spacer and two molecules of (+)-usnic acid as pincers. The ability of this molecular tweezer to bind 2,4,7-trinitrofluorenone was studied.

Cancer Medicine, Volume 15, Issue 4, April 2026.ABSTRACT Metastatic castration‐resistant prostate cancer (mCRPC) is the most aggressive kind of prostate cancer (PCa). Because the traditional taxane‐based therapy is ineffective, cabazitaxel (CBZ), a second‐generation, semisynthetic taxane, has been developed.

An improved phylogeny and revised taxonomy of Catillariaceae (Lecanoromycetes, Ascomycota)
TAXON, Volume 75, Issue 2, April 2026.Abstract The boundaries of the family Catillariaceae have largely remained untested through phylogenetic methods. Recent studies have led to the transfer of several genera previously classified in Catillariaceae to the newly described family Leprocaulaceae. Despite these changes, the distinction between Catillariaceae, Leprocaulaceae, and Catinariaceae

: Mitodepressive, clastogenic and biochemical effects of (+)-usnic acid in mice.
, 1991 Mice were treated orally with aqueous suspensions of (+)-usnic acid in a single dose of either 100 or 200 mg/kg. The effects on femur cells and proteins and on nucleic acids of liver cells were studied 24-72 h after treatment. (+)-Usnic acid was found to

Strengths and Limitations of Sodium Lauryl Sulfate as an Irritant Control in Patch Testing
Contact Dermatitis, Volume 94, Issue 4, Page 338-346, April 2026.Positive SLS reactions occurred in 22% of 43 478 patients and correlated predominantly with irritant‐prone allergens. Thirty‐one of 189 allergen preparations showed significant associations, strongest for cocamidopropyl betaine, formaldehyde, sorbic acid and DPG. A simple positive/negative SLS classification was diagnostically sufficient.
