Using molecular networking-guided isolation, three new galloyl ester triterpenoids (-), two new hexahydroxydiphenic acid-conjugated triterpenoids ( and ), and four known compounds (, , , and ) were isolated from the fruits and leaves of . The chemical structures of -, , and were elucidated on the basis of interpreting their NMR, HRESIMS, and ECD spectra. All compounds (-) were evaluated for their glucose uptake-stimulating activities in differentiated adipocytes using 2-deoxy-2-[(7-nitro-2,1,3-benzoxadiazol-4-yl)amino]-d-glucose as a fluorescent-tagged glucose probe. Compounds and resulted in a 1.5-fold increase in glucose uptake. Among them, compound from the fruits showed an upregulation of p-AMPK/AMPK ratio in differentiated C2C12 myoblasts to support the mechanism proposed of glucose uptake stimulation.

A comprehensive phytochemical investigation of aerial parts obtained from L. led to the isolation of 14 terpenoids (-) and nine polyphenols (-). The sesquiterpenoid group (-) included three structural families, namely, elemanolides (-), eudesmanolides ( and ), and germacranolides (-) with four unreported secondary metabolites (-), whose structure has been determined by extensive spectroscopic analysis, including 1D/2D NMR, HR-MS, and chemical conversion.

Aims: The present study aimed to provide summarized data related to the phytocompouds improving glucose uptake in the diabetic state.
Background: Glucose uptake in peripheral tissues such as skeletal muscle and adipose tissue is considered as an important step in the regulation of glucose homeostasis. Reducing high blood glucose levels in diabetic patients via targeting peripheral glucose uptake is a promising strategy to develop new antidiabetic medications derived from natural products.

Under the guidance of LC-MS/MS-based molecular networking, seven new verrucosidin derivatives, penicicellarusins A-G (-), were isolated together with three known analogues from the fungus . The structures of the new compounds were determined by a combination of NMR, mass and electronic circular dichroism spectral data analysis. The absolute configuration of penicyrone A () was corrected based on X-ray diffraction analyses.

Diabetes mellitus is a non-communicable disease entity currently constituting one of the most significant health problems. The development of effective therapeutic strategies for the prevention and/or treatment of diabetes mellitus based on the selection of methods to restore and maintain blood glucose homeostasis is still in progress. Among the different courses of action, inhibition of dipeptidyl peptidase IV (DPP-IV) can improve blood glucose control in diabetic patients.
