Summary
Moderate growth inhibition was obtainable in several transplantable tumors by the feeding of β-3-thienylalanine in diets lacking phenylalanine.
The effects of β-3-thienylalanine and deoxypyridoxine were additive in inhibition of the growth of Murphy-Strum lymphosarcoma; this inhibition was further increased by testosterone, Halotestin, and Nilevar.
Small amounts of phenylpyruvate used with small doses of β-3-thienylalanine and deoxypyridoxine appeared to be of greater advantage to the host than to the tumor.
