The article describes approaches for the synthesis and analysis of isotopically (2H, 3H, 13C, 14C, 35S) labelled drugs necessary for the development of a pharmacologically active compound into a registered drug. Special features such as isotope effec

Isotopic fractionation in HPLC can be observed for mianserin when deuterated in the piperazine ring, except on position 14b. This isotope effect is caused by an increase in basicity upon introduction of deuterium. No effects of deuteration on the con

Although the chemical structures of the antidepressants mirtazapine and mianserin are closely related there are considerable differences in their biological properties. To find an explanation of this, various physicochemical properties of mirtazapine
