Antifungal properties of 2‐N‐alkyn‐1‐ols

Abstract

Fourteen 2‐n‐alkynols (C3‐C14, C16, and C18) were tested against Aspergillus oryzae, Aspergillus niger, Trichoderma viride, and Myrothecium verrucaria in Sabouraud dextrose agar at pH 5.6 and 7.0. Toxicity to Candida albicans, Candida tropicalis, Trichophyton mentagrophytes, and Mucor mucedo was determined in the same medium at pH 5.6 and 7.0 in the absence and presence of 10% beef serum. Fungitoxicity was strongly influenced by chain length, slightly by the pH of the medium, and significantly by the presence of beef serum. 2‐n‐Undecyn‐1‐ol was the most active member of the series, and there was marked synergism between it and ketoconazole.
