Synthese von Moosinhaltsstoffen. 8. Sphagnums�ure und ihre Abbauprodukte
摘要:
For Sphagnum acid (1) and its enzymatic degradation product 5-hydrosy-4-(4-hydroxyphenyl)-5N-furan-2-on (2) efficient syntheses on preparative scale were developed, For the (4-hydroxyphenyl)butenolide 2 some characteristic chemical transformations are observed in acidic and basic medium.
The present study reports a series of novel potent farnesyltransferase inhibitors from chemical modifications of the lead compounds, such as compound 13n with an IC50 value of 0.0029 μM.
