A massive phytochemical survey by the U.S. Department of Agriculture [610] has identified a number of useful sources of L-dopa, the most promising being cultivated velvet beans. However, the microbiological hydroxylation of A-formyl-L-tyrosine esters [436] can be duplicated chemically in excellent yield by the use of benzoyl peroxide in chloroform [611]. Reports state that L-dopa from Japanese sources is superior to that from the U.S.A. [612]. Suitability of patients for L-dopa therapy can be assessed by determination of homovanillic acid and 5-hydroxyindole-3-acetic acid levels before and after treatment with probenecid [613, 614]. This drug reduces the outflow of brain monoamine metabolites into the blood and provides an index of the degree of...
