Synergistic combinations of a squalene epoxidase inhibitor and a leucyl-tRNA synthetase inhibitor are provided, which are useful in particular in the treatment of diseases involving fungal or suspected fungal infection, for immunomodulation or immunosuppression in conditions in which fungal or suspected fungal colonisation of e.g. the skin or nail plays a role, such as atopic dermatitis, acne vulgaris, seborrhoeic dermatitis, rosacea or onychomycosis, and in situations of fungal resistance.
