This review concentrates on some specific aspects of the chemistry of
allergic contact dermatitis. The way low molecular weight chemicals re
act with skin proteins to form complete antigens will be discussed and
the development of molecular modelling techniques to analyse molecula
r recognition presented. Subsequently, how knowledge of the chemical s
tructure can be used to estimate the allergenic activity of a molecule
will be considered. This aspect includes work with qualitative and qu
antitative structure-activity relationships (SAR) in the field of cont
act allergy.
