BM 21.0955, a potent new bisphosphonate to inhibit bone resorption.

A total of 300 new bisphosphonates were screened for their effect on bone resorption in the rat. Among these, 1-hydroxy-3-(methylpentylamino)propylidenebisphosphonate (BM 21.0955) was selected for detailed investigation.

Synthesis of thioether phosphocholine analogues.

The synthesis of thioether phospholipids, which represent a new class of antitumor agents, is reported here. In particular, the route of synthesis of 3-hexadecylmercapto-2-methoxymethylpropyl-2'-trimethylammoni o-ethyl phosphate (BM 41.440, Ilmofosine), one of the most potent cytostatic/cytotoxic derivatives, is described in detail.

[Acylaminoalkyl substituted benzoic and phenylalkane acids with hypoglycaemic properties (author's transl)].

Newly developed carbonic acids with hypoglycaemic properties are presented. Their activity is based on an insulin secretion with unusual biphasic dynamics which is seen both after enteral and parenteral administration. In vitro, the substances described have an inhibitory effect on gluconeogenesis in the liver and lipolysis in adipose tissue.
