Structure-activity relationships of the antifungal aminobisabolene natural product, 1 isolated from Halichondria sp., and synthetic analogs were explored, in parallel with the antidermatophytic allylamine, Terbinafine®, against a panel of pathogenic fungi: Candida spp., Cryptococcus spp. and Trichophyton rubrum. Interpretation of the results suggest different modes of action in antifungal activity for the two classes of compounds.

Background: Plant diseases cause huge losses in agriculture worldwide every year, but the prolonged use of current commercial fungicides has led to the development of resistance in plant pathogenic fungi. Therefore, there is an urgent need to develop new, efficient, and green fungicides.
Results: Twenty-three nootkatone-based thiazole-hydrazone compounds were designed, synthesized, and characterized by Fourier-transform infrared (FTIR), proton (H) nuclear magnetic resonance (NMR), carbon-13 (C) NMR, and high-resolution mass spectrometry (HRMS).

Infectious diseases, including bacterial, fungal, and viral, have once again gained urgency in the drug development pipeline after the recent COVID-19 pandemic. Tuberculosis (TB) is an old infectious disease for which eradication has not yet been successful. Novel agents are required to have potential activity against both drug-sensitive and drug-resistant strains of Mycobacterium tuberculosis (Mtb), the causative agent of TB.

Natural products (NPs) play a crucial role in drug discovery, with over 30% of recent FDA-approved drugs derived from them. Plants from the genus Goniothalamus, belonging to the Annonaceae family, have garnered significant interest as potential sources of active lead compounds. Over the past five decades, researchers have isolated 357 compounds from Goniothalamus species (GCs), which exhibit a wide range of pharmacological properties, including cytotoxicity, antibacterial, antifungal, antiplasmodial, antioxidant, and other activities.

In the last decades fungal infections became a major threat to human health having an unacceptably occurrence, a high rate of mortality and the number of patients at risk for these infections continue to increase every year. An effective, modern and very useful strategy in antifungal therapy is represented by the use of chimeric and hybrid drugs, most of them being with azaheterocycle skeleton. In this review, we present an overview from the last five years of the most representative achievements in the field of chimeric and hybrid diazine derivatives with antifungal properties.
