Phosphocalyculin a

WebCalyculin C, a minor derivative of the calyculins, has an additional methyl group on C32 of calyculin A. A recent biosynthetic study of calyculins revealed that an end product of calyculin biosynthesis is the pyrophosphate form, phosphocalyculin A. However, the pyrophosphate counterpart derived from calyculin C had not been reported. WebNov 15, 2014 · Phosphocalyculin C, although potent (IC 50 ¼ 36 nM vs. P388), is 5000 times less toxic than calyculin C itself. 22 A Chinese sediment-derived Actinoalloteichus …
