(6-OH-a-Me-Dopa) are reported. Hemodynamic studies in the rat have shown that this structural analogue and potential metabolite of the clinically useful drug (S)-a-Me-Dopa possesses weak hypotensive activity which resides in the R enantiomer. LDM studies in mice have established that 6-OH-a-Me-Dopa is over four times more toxic than a-Me-Dopa. Chronic exposure to 6-OH-a-Me-Dopa leads to renal and hepatic lesions. The ease of ...
