Abstract: The present invention provides a novel method for enhancing engraftment of haematopoetic stem cells by an ex-vivo pretreatment comprising the steps of obtaining a sample containing haematopoetic stem cells and admixing a prostacyclin analog to obtain a mixture, incubating said mixture for a period of time sufficient to stimulate G alphas-signalling in said cells and optionally and isolating said stimulated cells. Further, a composition comprising a prostacyclin analog for use in the treatment of individuals undergoing haematopoetic stem cell transplantation is provided.

Abstract: The present invention provides compositions comprising a prostacyclin or prostacyclin analog, or a pharmaceutically acceptable salt thereof for use in preventing or treating cystic fibrosis. The invention also provides the use of a kit comprising a prostacyclin or prostacyclin analog for treating or preventing a condition associated with cystic fibrosis in a subject.

Abstract: The present invention provides a composition comprising at least one prostacyclin or prostacyclin analog or a pharmaceutically acceptable salt thereof and at least one phosphodiesterase (PDE) 4 inhibitor and optionally a further PDE inhibitor for use in preventing or treating cystic fibrosis by selectively increasing the cAMP levels in bronchoepithelial cells.

Abstract: A method for the preparation of treprostinil and its derivatives is described. In contrast to prior art, this method utilizes an easily scalable enzymatic resolution of a key intermediate for making these compounds. Another significant improvement of the described method over prior methods is the regioselective Claisen rearrangement of a 5-allyloxy-benzaldehyde precursor, which is facilitated by a bromo substituent in 2-position.
