| pubmed-article:2936885 | pubmed:abstractText | Saturated analogues of poison ivy and oak allergens (3-alkylcatechols), i.e. trans,trans-3-alkyl-1,2-cyclohexanediols (alkyl = CH3, n-C5H11, n-C10H21, n-C15H31), have been prepared and used to sensitize guinea pigs. Only long-chain derivatives (carbon chain length greater than C10) are contact sensitizers. The sensitized animals cross-react to PDC (i.e. pentadecylcatechol, one of the allergens of poison ivy), but the converse is not true (PDC-sensitized animals do not react to cyclohexanediols). cis,trans-3-n-Pentadecyl-1,2-cyclohexanediol has also been synthesized and shown to be a sensitizer. There is not cross-reaction between trans,trans- and cis,trans-3-n-pentadecylcyclohexanediols, excluding a common skin metabolite. | lld:pubmed |
