title: [Preparation and experimental antitumor activity of a new semi-synthetic antibiotic: 14-diethoxyacetoxy daunorubicin (R.P. 33 921)].
abstract: 14-diethoxyacetoxy daunorubicin (R.P. 33 921) was chosen among a series of new daunorubicin analogues. Its preparation from daunorubicin and its biological activities are described. It displays an antitumoral activity in mice with a better chemotherapeutic index than daunorubicin and doxorubicin.
