  • Patent number: 6239308
    Abstract: The present invention provides a simple and inexpensive method for producing &agr;-hydroxy-&bgr;-aminocarboxylic acids and their esters. An ester of an N-protected &agr;-amino acid ester is converted into a &bgr;-ketosulfoxide, which is then processed with an acid to give an &agr;-ketohemimercaptal. Next, this is acylated and then processed with a base to obtain an N-protected &agr;-acyloxy-&bgr;-amino-thioester, which is then saponified to obtain an intended compound. According to the method of the present invention, it is possible to produce &agr;-hydroxy-&bgr;-aminocarboxylic acid derivatives, which are intermediates in producing various HIV protease inhibitors, renin inhibitors and carcinostatics, from a-amino acids. The method comprises reduced reaction steps, the selectivity in the method to give the intended product is high, and the yield of the product obtained is high.

    Abstract: A new family of inadone and tetralone tubulin-binding compounds (TBs) is disclosed. Unlike classical TBs, which inhibit mitosis among affected dividing cells, the TBs of the invention possess two unique properties: (1) they induce apoptosis among stationary phase (non-dividing) malignant cells, yet do not impair the viability of normal nonproliferating cells; and, (2) they affect cells which have acquired MDR more powerfully than they affect cells without MDR. Thus, the TBs of the invention provide means to target malignant cells for chemotherapy, even after previous therapies have failed, without affecting normal cells and tissues in the host.
