Biotransformation of jervine (1) by Cunninghamella echinulata (ACCC 30369) was carried out. Four biotransformation products were obtained, and three of them, 3–5, were identified as new compounds. On the basis of their NMR and mass‐spectral data, their structures were characterized as jervinone (2), 7α‐hydroxyjervine (3), 14α‐hydroxyjervine (4), and 1β,7α‐dihydroxyjervine (5). The X‐ray diffraction
The invention relates to a method of treating cancer. The method includes administering systemically a therapeutically effective amount of a small molecule hedgehog pathway inhibitor, such that the concentration of the inhibitor in the blood does not vary by more than about ±30% from the average concentration, and such that the concentration remains at or below the maximum tolerated dose of the inhibitor for a time period of at least about one day.
