Lisofylline (LSF) is a synthetic small molecule with novel anti-inflammatory properties. LSF can effectively preventtype 1 diabetes in preclinical models and improves the function and viability of isolated or transplantedpancreatic islets. It is ametabolite ofpentoxifylline.

As well, LSF improves cellularmitochondrial function and blocksinterleukin-12 (IL-12) signaling andSTAT-4 activation in target cells and tissues. IL-12 and STAT-4 activation are important pathways linked to inflammation and autoimmune damage toinsulin producing cells. Therefore, LSF and related analogs could provide a new therapeutic approach to prevent or reversetype 1 diabetes. LSF also directly reducesglucose-induced changes in human kidney cells suggesting that LSF and analogs have the potential to treat the complications associated with diabetes.

Synthesis

[edit]

TheR enantiomer of the pentoxyfylline analogue in which the ketone has been reduced to an alcohol shows enhanced activity as an inhibitor ofacetyl CoA over the parent drug.

Lisofylline synthesis:U.S. patent 5,567,704 NB[1][2][3][4][5][6][7]
