A method for detecting phospholipase D (PLD) activity in a cell, comprising: (i) stimulating endogenous PLD in said cell for said PLD to catalyze a transphosphatidylation reaction between phosphatidylcholine or a derivative thereof and an exogenous functionalized alcohol to form a phosphatidyl alcohol, wherein the functionalized alcohol possesses a first functional group that can react with and form a bond to a functionalized detectable label having a second functional group reactive with the first functional group, and said phosphatidyl alcohol contains said first functional group in available form; (ii) reacting said phosphatidyl alcohol with said functionalized detectable label under conditions where said functionalized detectable label reacts, via its second functional group, with the first functional group to form a linkage between said detectable label and said phosphatidyl alcohol so as to form a labeled phosphatidyl alcohol containing said detectable label; and (iii) detecting said labeled phosphatidyl alcohol.

Fermentation processes that use fungi of the genus Ulocladium for producing novel compounds that include an 8- or 9-membered cyclic structure, wherein an (E)-1,4-dioxo-but-2-ene moiety is embedded in the cyclic structure. The compounds may be used as medicaments, in particular as medicaments for treating and preventing microbial infections, such as infections by multidrug resistant and/or Gram-positive bacteria.
