Enantiospecificity in allergic contact dermatitis A review and new results in Frullania‐sensitive patients

Abstract
Allergic contact dermatitis is essentially enantiospecific: sensitization to one enantiomer generally does not imply elicitation to the mirror-image allergens. Examples from patients allergic to Frullania, and from the literature (usnic acids, 4-methoxydalbergiones, .gamma.-methyl-.alpha.-methyl-.alpha.-methylene-.gamma.-butyrolactones, frullanolides) are discussed.
