Excerpt from A Study of the Preparation of Cyclic Azo Compounds and the Structure of Naphthalene, Tetralin and HydrindeneThe mechanism whereby certain hydrocarbons start normal cells on a career of malignancy is entirely unknown, and if a chemical reaction is involved, the nature of the change is quite obscure. Most of the carcinogenic hydrocarbons are more susceptible to oxidation than to other reactions, but there is no evidence that an oxidation is involved. The high degree of specificity in structure among the derivatives of 1, 2-benzanthracene is difficult to reconcile with the hypothesis that an agent of a certain reducing intensity is required to initiate malignant growth, and this same specificity probably rules out the explanation based upon the conception of a chronic irritation. Possibly the molecular dimensions and the surface activity of the substances are as important as their chemical characteristics.The experimental work on this particular problem was found to be rather difficult, and time-consuming. Many steps were involved in the synthesis of the one cyclic azo compound which has been prepared, and the yield diminished with each step. This meant constant repetition, so that we are only now really ready to start on the problem.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
