[Problems] To provide an antibacterial agent, particularly a novel polypeptide compound having an antifungal action.
[Means for Solution] As a result of an extensive study on a novel antifungal agent, the inventors have found that an excellent anti-deep-fungal activity is exhibited by introducing a cyclohexylmethylamino group or a piperidylmethylamino group as a partial structure of a natural polypeptide compound, and completed the present invetion.
The compound of the present invetion has an excellent antibacterial activity and is therefore useful as an agent for preventing or treating various fungal infections.
