Uses
VU0359595 is an inhibitor of phospholipase D1 (PLD1) which is more than 1700 fold selective over phospholipase D2 (PLD2). This complex only binds and inhibit phospholipase D though an allosteric site, but it noes not interact with the catalytic site of phospholipase D.
Biological Activity
vu0359595 is a potent and selective inhibitor of pld1.phospholipase d (pld) isozymes mediate phospholipid hydrolysis and transphosphatidylation. until now, two mammalian isoforms of pld, pld1, and pld2, have been identified. it has been identified that pld has been implicated in a human cancer cell progression, actin cytoskeleton reorganization and cell motility [1].
in vitro
vu0359595 was an inhibitor of pld1 with an ic50 of 3.7 nm. vu0359595 showed >1,700-fold selectivity over pld2. the ic50 of was vu0359595 against pld2 was 6.4 μm [1]. preliminary evidence has demonstrated that vu0359595 showed no interaction with the catalytic site of pld, but may bind and inhibit pld through an allosteric site [1]. at 500 nm, vu0359595 significantly reduced the pld activity in astroglial cultures from wild-type mice by 58% [2]. in cells stimulated by 1% fcs, vu0359595 decreased cell proliferation in wild-type and pld2-deficient cells at a concentration of 500 nm [2]. vu0359595 (500 nm) significantly reduced cell growth in cells stimulated by either mitogen [2].
IC 50
PLD1: 3.7 nM (IC50); PLD2: 6.4 μM (IC50)
