Two new benzoquinones, citriquinone A (1) and B (2), were isolated from the methanol extract of a soil fungus, Penicillium citrinum. The structures of the new compounds were determined on the basis of detailed spectroscopic analysis. Citriquinone A (1) exhibited antibacterial activity against Bacillus sp. and cell migration inhibitory activity (CMIA) against human cancer cell line HEp 2.

One new monomeric citrinin analog (1) and 42 known compounds (2-43) were isolated from Penicillium citrinum W22. The structure of 1 was determined by detailed analysis of the 1D and 2D nuclear magnetic resonance (NMR), HRESIMS, and time-dependent density functional theory (TD-DFT)-based electronic circular dichroism (ECD) calculation. Penicitrinol A (2) and methyl 2-(2-acetyl-3,5-dihydroxy-4,6-dimethylphenyl) acetate (11) significantly inhibited renin-angiotensin system-selective lethal 3 (RSL3)-induced ferroptosis with half maximal effective concentration (EC) values of 1.

Metabolic alterations are commonly associated with various cancers and are recognized as contributing factors to cancer progression, invasion, and metastasis. Drug repurposing, a strategy in drug discovery, utilizes existing knowledge to recommend established drugs for new indications based on clinical data or biological evidence. This approach is considered a less risky alternative to traditional drug development.

Microbial attack, particularly fungal degradation of cellulose, is a leading cause of paper damage. To address fungal spores and the rising concern of microbial drug resistance, a nano-Germanium dioxide (GeO)/cetyltrimethylammonium bromide (CTAB) complex (nano-GeO/CTAB complex) with potent antibacterial properties was synthesized. Its inhibitory effects were evaluated against bacteria, including Gram-positive and Gram-negative , as well as fungi isolated from paper ( spp.
