What is described are compounds of formula (1)
wherein
L
1
is derived from an ether (R
1
—OR
2
)
m
, wherein R
1
and R
2
are independently selected and are derived from a hydrocarbon having 1 to 12 carbon atoms, with m being an integer from 1 to 4, or from a hydrocarbon R having 1 to 20 carbon atoms; F is unsubstituted or substituted pyrene as a fluorophore; Q is a quencher, and
L
2
is C(O)-L
1
or C(O)-L
1
-NH, wherein L
1
is as defined above. These compounds may be used to determine the activity of phospholipase A
2
, in particular PAF-AH.
所描述的是化合物的公式(1),其中L1源自醚(R1-OR2)m,其中R1和R2是独立选择的,并源自具有1至12个碳原子的碳氢化合物,m为1至4的整数,或源自具有1至20个碳原子的碳氢化合物R;F是未取代或取代的
芘作为荧光团;Q是淬灭剂,
L2是C(O)-L1或C(O)-L1-NH,其中L1如上定义。这些化合物可用于确定
磷脂酶A2的活性,特别是PAF-AH。
