Tierexperimentelle Untersuchungen mit α-Methyl-Dopa-14C unter besonderer Berücksichtigung der optischen Isomeren

Abstract: Dowex 50 (H®-Form) gerührt. Die Essigesterlösung lieferte beim Eindampfen i. Vak. zunächst öliges pMZ-L-Isoleucin, das, in Benzol gelöst, mit Dicyclohexylamin versetzt wurde. Das Dicyclohexylammoniumsalz (Schmp. 144 -145°, aus A lkohol/Petroläther farblose Nadeln) lieferte nach der Zerlegung mit Dowex 50 9,5 g (65%) pMZ-L-Isoleucin in schönen Nadeln, Schmp. 64 -66 , + 1 2 ,4° (c = 2 in Eisessig).C15H21N 0 5 (295,4) Die Darstellung erfolgte analog der voranstehenden Verbindung. Nach der Reinigung über das Dicyc… Show more

“…Synthesis of I4C-labelled D-and L-oc-methyldopa DL-3 -(3',4'-Dihydroxyphenyl) -2-methyl[3 -'IC]alanine was prepared by the method of Duhm et al (1965) starting with Ba14CO3 (from The Radiochemical Centre, Amersham, Bucks., U.K.). The amount of DL-[14C]-oc-methyldopa obtained was 1.03g, of specific radioactivity 1.15,uCi/mg; m.p.…”
