Influences of the chemical structure on the activity of new inhibitory compounds of the angiotensin-converting enzyme.

The ACE inhibitory activity of some perimidines, chinazolinones and amidinohydrazones is described. Relations were found between the chemical structure and the inhibitory activity on the ACE.

[Process for producing fluorescein for injection purposes (author's transl)].

The authors report of a process for producing high-purity fluorescein for injection purposes which is characterized by the fact that synthesis-induced by-products are separated from the raw fluorescein, obtained by any process, by means of a clean-up chain consisting in step-by-step monoacetylation in an aqueous-alkaline solution, subsequent diacetylation in pyridine or a pyridine-glacial acetic acid mixture, saponification of the diacetyl product by sodium methoxide in methanol, and precipitation of the fluorescein with anhydrous formic acid.
