Method of inhibiting lung tumors, arylalkyl isothiocyanates, and method of synthesizing same
First Claim
1. A method comprising treating a mammal with an isothiocyanate adapted for inhibiting lung tumor multiplicity and/or incidence, said isothiocyanate being administered in the diet of said mammal in an amount effective to inhibit said lung tumor multiplicity and/or incidence, wherein the isothiocyanate is selected from the group of isothiocyanates having the formula:
- ##STR5## wherein n is an integer greater than or equal to 2 and less than or equal to 6.

Abstract
A method of inhibiting lung tumor multiplicity and/or incidence by treating mammals with relatively long chain arylalkyl isothiocyanates, especially effective with respect to tumors induced by exposure to tobacco-specific nitrosamine. Among the isothiocyanates are 4-phenylbutyl isothiocyanate, phenylpentyl isothiocyanate and phenylhexyl isothiocyanate, which are synthesized by adding hydrochloride of phenylbutylamine, phenylpentylamine, or phenylhexylamine in water to thiophosgene in an inert organic solvent. For comparison testing, oxo-pyridyl butyl isothiocyanate is synthesized by dissolving myosmine in HCl to obtain a hydrochloride salt, suspending the salt in dry chloroform, adding thiophosgene, and adding chloroform containing triethylamine.
