The Conversion of (+)-Dehydroabietic Acid into Steroidal Hormones [PDF]

Bulletin of the Chemical Society of Japan, 1988
Abstract A resin acid, (+)-dehydroabietic acid, was converted into 3,4,4a,9,10,10a-hexahydro-7-methoxy-10aβ-methyl-4aαH-phenanthren-1(2H)-one (2) by the introduction of oxygen functions at the C-4 and C-13 positions, and a rearrangement of the angular methyl group to the C-5 position.

Epidemiological Comparative Study on Contact Sensitisations in Woodworkers With Occupational Dermatitis: Patch Test Data of the Information Network of Departments of Dermatology, 1999 to 2023

Contact Dermatitis, Volume 94, Issue 2, Page 125-136, February 2026.
The data demonstrates that allergic contact dermatitis is common in WW with OD. The most important allergens include resins (including epoxy resin) and plant‐derived substances (including colophonium). The high share of WW with allergic contact dermatitis and face dermatitis hampers preventive efforts.

Analysis of the Functional Components of Four “Sanghuang”‐Like Species Using UPLC‐ESI‐MS/MS‐Based Widely Targeted Metabolomics and TCMSP Database

Journal of Food Biochemistry, Volume 2026, Issue 1, 2026.
“Sanghuang” is a rare, edible, medicinal macrofungus. However, various macrofungi that share similar appearances, habitats, and therapeutic effects with “Sanghuang” have been erroneously used in traditional folk medicine. As of date, metabolic differences among these “Sanghuang”‐like species have been unclear, impeding their commercial utilization ...
