Latest Patents

Fraefel's latest patents include a process for the preparation of sphingosine derivatives. These new compounds, such as D- and L-erythro-1-(.beta.-D-glycopyranosyloxy)-3-hydroxy-2-palmitoylamino-4-trans-octadecene, are designed to exert actions that promote wound healing and cell and tissue regeneration. The compounds can be therapeutically used for treating wounds of any cause. The preparation process yields these compounds in a stereochemically homogeneous form from ceramides, involving several steps including protection of the 1-hydroxyl group and esterification of the 3-hydroxyl group.

Another significant patent involves the preparation of cell and tissue regenerating substances. This process isolates glycolipids with regenerative properties from mammalian blood or organ homogenates through autolysis and dialysis against an alcoholic-aqueous medium. The resulting glycolipids can be purified through precipitation or chromatography, yielding active compounds suitable for industrial application.
