naphthoquinones and Sarcoma--Kaposi

Eleven cases of patients bearing basic cellular carcinoma, and one case of patient bearing Kaposi's sarcomatosis, all treated with antibiotics isolated by Goncalves de Lima and Co-workers at the Instituto de Antibióticos, are presented by the authors. Primin, an antibiotic extracted from a vegetal named Miconia sp. (Herb. I.A.-1903) with a 2-metoxi-6-n-pentil-p benzoquinone structure, presented a strong antineoplastic action in the cases treated. Plumbagin isolated from Plumbago scandens in local use, was responsible for a complete healing of the injuries treated. Maytenin extracted from Maytenus sp. (Herb. I.A.-1750) showed less activity than the two previous mentioned, but with a low irritant action and late antineoplastic properties. The authors are going on these experiments. They believe that these antibodies, in local use, may advantageously substitute the surgery and the radiotherapy, meanly in those external ear tumidities and back of the nose, owing to a hurtful action in cartilage, provoked by radiotherapy.
