Structure modification and biological activity of some griseofulvin derivatives.
Griseofulvin is an orally acting anti-fungal antibiotic with very limited water solubility. Five chemical modifications were made on the griseofulvin structure in order to evaluate these changes on the antifungal and water solubility properties. Antifungal activity was measured against Tricophyton mentagrophytes, T. rubrum, T. terrestre, and Microsporum canis. The oxime of griseofulvin was the most potent of the five compounds tested, but it was only of equal or less potency than griseofulvin. The somewhat increased water solubility of some of these compounds was offset by the lower anti-fungal potency of the structural modification.
