Bioinspired Synthesis of Twin abeo‐Steroids Bufogargarizins A and B via a Divergent Intramolecular Aldol Addition Reaction

open access: yesAngewandte Chemie, Volume 138, Issue 2, 9 January 2026.
Twin natural products. This manuscript describes a concise biomimetic synthesis of twin abeo‐steroids bufogargarizins A and B with an unusual [7.5.6.5] and [5.7.6.5] skeletons in 19 steps (LLS). The described synthetic approach features the application of a bioinspired regiodivergent intramolecular aldol addition reaction and a selective singlet oxygen‐

Triterpene glycosides from Astragalus icmadophilus

open access: yesPhytochemistry, 2010
Six cycloartane-type triterpene glycosides were isolated from Astragalus icmadophilus along with two known cycloartane-type glycosides, five known oleanane-type triterpene glycosides and one known flavonol glycoside. The structures of the six compounds were established as 3-O-[alpha-L-arabinopyranosyl-(1-->2)-O-3-acetoxy-alpha-L-arabinopyranosyl]-6-O ...

The Effect of Myrtacine and Celastrol‐Enriched Extract on Cutibacterium acnes Extracellular Vesicles

open access: yesInternational Journal of Dermatology, EarlyView.
Myrtacine alone, Celastrol‐enriched extract alone, or the combination of both ingredients were added to the culture medium either before (preventive condition) or after (modulating condition) incubation with C. acnes IA1 extracellular vesicles (EVs) from healthy and acne skin in immortalized keratinocytes (HaCaT cells) and human skin explants.

Methodology for the Construction of the Bicyclo[4.3.0]nonane Core

open access: yesMolecules, 2016
The bicyclo[4.3.0]nonane scaffold, commonly known as a hydrindane, is a common structural motif found in many terpenoid structures and one that remains a challenge for synthetic chemists to elaborate with appropriate regio- and stereo-selectivity.

Chromosome‐Scale Haplotype Genome Assemblies for the Australian Mango ‘Kensington Pride’ and a Wild Relative, Mangifera laurina, Provide Insights Into Anthracnose‐Resistance and Volatile Compound Biosynthesis Genes

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Mango (Mangifera indica) is one of the most popular fruits cultivated in tropical and subtropical regions of the world. The availability of reference genomes helps to identify the genetic basis of important traits. Here, we report assembled high‐quality chromosome‐level genomes for the Australian mango cultivar ‘Kensington Pride’ and M ...

Unveiling protective mechanisms of wild olive (acebuche) oil in retinal pigment epithelial cells with hypertensive phenotype

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Circulating extracellular vesicles (EVs) derived from acebuche (ACE) oil‐ and extra virgin olive oil (EVOO)‐fed mice modulate nitric oxide (NO) metabolism in the retinal pigment epithelial cell line (ARPE19) with a hypertensive phenotype induced by angiotensin II (AngII).
