Abstract: Anthracycline glycosides of the general formula (I): ##STR1## wherein R.sub.1 represents a hydrogen atom or a hydroxyl group, one of R.sub.2 and R.sub.3 represents a hydrogen atom and the other of R.sub.2 and R.sub.3 represents a hydrogen atom or a hydroxyl group; and pharmaceutically acceptable acid addition salts thereof are antitumor agents. These glycosides may be prepared from a daunomycinone derivative of formula (II): ##STR2## in which the 4-amino group is protected. 4-Demethoxy-4-amino-daunomycinone (II) and an earlier intermediate in its preparation, 4-demethoxy-4-amino-7-deoxy-daunomycinone (IX), can be diazotized followed by mild reduction to form 4-demethoxy-daunomycinone or 4-demethoxy-7-deoxy-daunomycinone respectively. 4-Demethoxy-daunomycinone can be converted into another antitumor anthracycline glycoside, 4-demethoxy-daunorubicin.

Abstract: According to the invention there is provided a sterile, pyrogen-free, ready-to-use solution of an anthracycline glycoside, especially doxorubicin, which consists essentially of a physiologically acceptable salt of an anthracycline glycoside dissolved in a physiologically acceptable solvent therefor, which has not been reconstituted from a lyophilizate and which has a pH of from 2.5 to 6.5. The solution of the invention is particularly advantageous for the administration by injection of the anthracycline glycoside drugs, e.g. doxorubicin, in the treatment of both human and animal tumors.

Abstract: A new process for the preparation of 6-deoxyanthracyclinones of general formula I: ##STR1## wherein R represents a hydrogen atom, a hydroxy group or a lower alkoxy group is described. The process provides a total synthesis of the 6-deoxyanthracyclinones of formula I using 1,2,3,6-tetrahydro-phthalate as starting material. The obtained racemic mixture of the compounds of formula I, if desired, can be submitted to optical resolution by the conventional method of conversion to diastereomeric derivatives using a chiral resolving agent. Alternatively, the racemic mixture can be used as such for the condensation with a suitably protected halosugar derivative to obtain alpha glycosidic derivatives of formula XV: ##STR2## wherein R.sub.1 represents a hydrogen atom or a hydroxy group, one of R.sub.2 and R.sub.3 represents a hydrogen atom, the other of R.sub.2 and R.sub.3 represents a hydrogen atom or a hydroxy group and X is a hydrogen atom or a trifluoro acetyl group.

Abstract: The invention relates to an apparatus for connecting a bottle containing a medicament to a syringe the needle of which is housed in a closed chamber defined by the apparatus and from which the needle can be made to emerge by sliding the separate constituent parts of the appartus along each other. To prevent the needle from emerging from the chamber when no bottle is housed in the appropriate seat provided in the apparatus, there extends from one of the parts of the apparatus an elongated flexible appendix having at least one protuberance which projects into the seat and against which the bottle presses when inserted into the seat, so bending the appendix outwards. In front of the free end of the appendix there is provided a stop tooth projecting from that consituent part of the apparatus which is projecting from that constituent part of the apparatus which is mobile along the first part and extends totally around the seat.
