L-651,582, is an antiproliferative, antiangiogenic, antimetastatic and antiparasitic agent, which is also selective towards numerous mismatch repair-deficient tumor cell lines in vitro. It is a voltage-gated L-type Ca2+ channel blocker with an IC50 of 0.5 µg/ml . Patch clamp measurements of current through L- and T-type channels in guinea pig atrial cells also indicate that L-651,582 is a Ca2+ antagonist5. Block of L-type calcium channels is voltage-dependent and the apparent dissociation constant for the high affinity state is 0.2 µg/ml. The IC50 for block of T-type Ca2+ channels is 1.4 µg/ml.
产品描述
An Effective Blocker of L-Type CaV Channels
产品形式
Two subtypes of voltage-Gated Ca2+ Channels (VGCC, CaV) are found in most nonexcitable cells, the T-type (CaV3) and the L-Type (CaV1) Ca2+ channels.
