The Relationship

Benzoquinones such as primin (2-methoxy-6-pentyl-1,4-benzoquinone) from Primula obconica HANCE (Primulaceae) are known to be strong sensitizers and thus the source of severe allergic contact dermatitis (cell-mediated type of allergy). In order to determine the relationship between sensitizing capacity and chemical structure the synthesis of 19 side-chain-modified analogues of primin was carried out. With each of these primin derivatives 10 guinea pigs were sensitized using a modified FCA-method (FCA = Freund’s complete adjuvant). Elicitation was done open epicutaneously with 0.001 molar concentrations. In these sensitization experiments 2-methoxy-6-alkyl-1,4-benzoquinones (chain length C1-C15) showed ascending sensitizing potency with increasing number of the side chain carbon atoms reaching maximum activity at an alkyl chain of 10 to 11 carbons. Beyond this point a decrease of the sensitizing potency in correlation with a further prolongation of the side chain was observed.

Cutaneous Administration

It has been shown that by the cutaneous administration of simple chemical compounds in small quantities—2:4:6 trinitrochlorobenzene (picryl chloride) and 2:4 dinitrochlorobenzene, the latter a typical incitant of contact dermatitis in man—it is possible to induce true anaphylactic sensitization in guinea pigs, demonstrable by the intravenous injection of protein conjugates and by the Dale technique, using isolated uterine horns. This furnishes strong evidence for the formation of antigenic conjugates following application of substances of simple chemical constitution. Since the anaphylactic state is induced by the same method of administration that gives rise to cutaneous sensitivity, the assumption would appear justified, when one takes into account the chemical properties of the inciting substances, that the formation of conjugated antigens offers an explanation for the skin effects also. In the experiments with picryl chloride, anaphylactic antibodies, and occasionally precipitins, have been demonstrated. The differences between the cutaneous and anaphylactic types of sensitivity are discussed.
