Characterisation of the Antifungal Effects of a Plant-based Compound, CIN-102, on the Main Septal Filamentous Fungi Involved in Human Pathology

Objectives: Today, the increase of invasive fungal infections and the emergence of resistant strains are observed in medical practice. New antifungals are expected, and the plant world offers a panel of potentially active molecules. CIN-102 is a mixture of seven different compounds of plant origin developed from the formulation of cinnamon essential oil.

Methods: The in vitro activity of CIN-102 was characterised against Aspergillus spp., Fusarium spp. and Scedosporium spp. by studying the minimum inhibitory concentration (MIC), inoculum effect, germination inhibition, fungal growth, post-antifungal effect (PAFE) and synergy.

Results: MICs determined for the three genera followed a unimodal distribution and their mean values ranged from 62-250 μg/mL. CIN-102 demonstrated an inoculum effect similar to voriconazole and amphotericin B, 100% inhibition of spore germination and a PAFE.

Conclusion: CIN-102 has significant activity against filamentous fungi involved in human pathologies and should be further explored as a potential new treatment. Other studies regarding its mechanisms of action as well as animal investigations are awaited.
