Atopic dermatitis (AD) is a common, chronic, and recurring inflammatory skin disease. Physalis alkekengi L. var. franchetii (Mast) Makino (PAF), a traditional Chinese medicine, is primarily used for the clinical treatment of AD. In this study, a 2,4-dinitrochlorobenzene-induced AD BALB/c mouse model was established, and a comprehensive pharmacological method was used to determine the pharmacological effects and molecular mechanisms of PAF in the treatment of AD. The results indicated that both PAF gel (PAFG) and PAFG+MF (mometasone furoate) attenuated the severity of AD and reduced the infiltration of eosinophils and mast cells in the skin. Serum metabolomics showed that PAFG combined with MF administration exerted a synergistic effect by remodeling metabolic disorders in mice. In addition, PAFG also alleviated the side effects of thymic atrophy and growth inhibition induced by MF. Network pharmacology predicted that the active ingredients of PAF were flavonoids and exerted therapeutic effects through anti-inflammatory effects. Finally, immunohistochemical analysis confirmed that PAFG inhibited the inflammatory response through the ERβ/HIF-1α/VEGF signaling pathway. Our results revealed that PAF can be used as a natural-source drug with good development prospects for the clinical treatment of AD.

To explore potential anti-inflammatory lead compounds, ten new physalin steroids, including three neophysalins (1, 4, and 9) and seven physalins (2, 3, 5-8, and 10), along with eleven known analogs, were isolated from an ethanol extract of the calyx of Physalis alkekengi. The new structures were rigorously determined through comprehensive HRESIMS, 1D/2D-NMR, and X-ray diffraction analysis. Among these compounds, 1 was identified as a new 1,10-seco-neophysalin, and 2 was identified as a new 11,15-cyclo-9,10-seco-physalin characterized by an aromatic A-ring.

Physalis alkekengi L. is recognized as a significant source of various secondary metabolites, particularly C steroidal lactones known as withanolides and physalins, renowned for their therapeutic properties with a rich history in traditional medicine. In this study, we characterized the sequences of key downstream genes (PaFPPS, PaSQS, PaSQE, PaCAS, PaHYD1, and PaDWF5-1) involved in the biosynthesis of withanolides, marking the first characterization of these genes in P.

This study aimed to elucidate the pigment composition and genetic mechanisms during fruit maturation in these species. Fruit samples were collected at four development stages, analyzed using spectrophotometry and high-performance liquid chromatography (HPLC), and complemented with transcriptome sequencing to assess gene expression related to pigment biosynthesis.

Article Synopsis
- Physalis alkekengi L.var. franchetii (PAF) is a valuable edible and medicinal plant in China, traditionally known for its medicinal properties, especially in its calyx and fruit.
- * A comprehensive study using UPLC-Q-Orbitrap-HRMS analyzed five parts of PAF, identifying 95 compounds, including unique aliphatic sucrose esters, and revealing chemical similarities between the root and stem.
- * The calyx, leaf, and fruit showed stronger antibacterial and anti-inflammatory effects compared to the stem and root, with 19 potential biomarkers linked to these activities discovered through advanced analysis techniques.
