Project description:Candida albicans is a prevalent fungal pathogen in humans worldwide, causing life-threatening invasive candidiasis in immunocompromised individuals, largely due to the scarcity and poor efficacy of present antifungals, necessitating the search for novel antifungal medications.By leveraging machine learning methodologies, we have identified a novel compound that demonstrates robust antifungal activity against C. albicans. To explore the mechanisms behind its efficacy, we undertook an extensive study involving transcriptomic profiling of C. albicansexposed to the compound across different cultivation times and doses.The findings of this study not only contribute to our understanding of antifungal mechanisms, but also have great potential to guide the development of innovative therapies against C. albicans for meeting the growing clinical demand for new treatments.

Project description:Fungal infections are a serious health problem in the clinic especially in the immunocompromised patient. Disease ranges from widespread superficial vulvovaginal infections to life-threatening systemic candidiasis. Especially for systemic mycoses only a limited arsenal of antimycotica are available, including azoles, polyenes, echinocandines and amphothericin B. Due to emerging resistance to standard therapy and significant side effects for some antimycotica there is a medical need for new antifungals in the clinic and general practice. In order to expand the arsenal of compounds with antifungal activities we screened compound libraries, including combinatorial libraries as well as more than 30 000 pure compounds derived from organic synthesis for antimycotic activity. In total more than 100 000 compounds were screened using an innovative AS (activity-selectivity) assay analyzing both the antifungal activity and the compatability with human cells at the same time. One promising hit, a Benzimidazol-2-yl-alkylamine derivative, was developed in a series of lead compounds showing potent antifungal activity. ((1S)-1-[1-(3-chlorobenzyl)-1H-benzimidazol-2-yl]-2-methylpropyl-amine) (EMC120B12) showed the highest antifungal activity and best compatability with human cells in several cell culture models and against a number of different yeasts and clinical isolates. Transcriptional profiling indicates that the newly discovered compound is a potential inhibitor of the ergosterol-pathway.

Transcriptional profiling indicates that the newly discovered compound is a potential inhibitor of the ergosterol-pathway. In total, three biological replicates were performed. All experiments were performed as dye swaps. Thus, in total six arrays have been hybridzed. Hybridization experiments included an untreated reference sample and a sample of cells treated with ((1S)-1-[1-(3-chlorobenzyl)-1H-benzimidazol-2-yl]-2-methylpropyl-amine) (EMC120B12). The array included one technical replicate of each probe.

Project description:The systemic infections by peptogenous fungi member of the genera Candida and Aspergillus represent a serious threat for public health. During previous research we have successfully identified a family of compounds active against different Candida spp. including strains resistant to antifungal drugs currently on the market. We have further refined our knowledge on this field by identifying a possible molecular target that could justify the activity of these compounds. The research of the mode of action of the compounds object of this manuscript was supported also by fluorescent microscopy of labeled derivatives. Transcriptional data indicates that one of the macrocyclic antifungal induces a drug response involving ATP binding cassette transporters. Moreover the data show that the macrocyclic antifungal decrease expression of cell wall biosynthesis genes. Moreover, the quality of the compounds and their potential was tested in vivo revealing a promising profile in particular against fungal infection caused by resistant strains Gene expression was measured in Candida albians CAF2-1 exposed to the macrocyclic compound FR59 at 3 µM at two time points (15 min and 45 min), The one-color system was used. Three independent experiments were performed using non-exposed cells, 15 min and 45 min exposed cells.
