[New anthracycline antibiotics and derivatives].

Studies of anthracycline antibiotics which have been carried out for the purpose of finding compounds useful in the treatment of cancer are described. Synthetic development of derivatives and analogs which have stronger activities and lower characteristic toxicities than parent antitumor antibiotics such as daunomycin, adriamycin, etc., have been illustrated namely: (1) syntheses of 4'-O-derivatives such as 4'-O-tetrahydropyranyl-adriamycin; (2) syntheses of N-alkyl derivatives such as 3'-deamino-3'-morpholino-adriamycin; and (3) syntheses of 11-deoxy-adriamycin. Notably, 4'-O-tetrahydropyranyl-adriamycin having a (2" R)-configuration has been confirmed to have stronger activity and lower toxicity than adriamycin by Phase II study. New, naturally occurring anthracycline antibiotics (decilorubicin, arugomycin, ditrisarubicin, etc.) have also been reviewed.

Delayed hypersensitivity in ampicillin-induced toxic epidermal necrolysis.

A patient with ampicillin-induced toxic epidermal necrolysis (TEN) showed pronounced delayed hypersensitivity to ampicillin sodium by both intradermal and patch tests. In addition, a positive lymphocyte transformation test to ampicillin was demonstrated by an in vitro study. On the basis of these findings and the data found in the literature, we believe that delayed hypersensitivity plays a crucial role in the development of drug-induced TEN. We recommend patch testing with suspected medication in such cases.
