IWP-4 is a Wnt inhibitor with an IC₅₀ of 25 nM. IWP-4 specifically inhibits casein kinase 1δ/ε (CK1δ/ε), with an IC₅₀ of 1.06 μM against wild-type CK1δ, 1.02 μM against the CK1δ kinase domain, and 7.07 μM against CK1ε; it shows enhanced inhibitory activity against the M82F CK1δ mutant (IC₅₀ = 0.14 μM). IWP-4 is applicable to research related to cancer, Alzheimer's disease (AD), and heart failure.

In Vitro

IWP-4 (48 h) inhibits the proliferation of all tested cancer cell lines, with submicromolar EC₅₀ values ranging from 0.23 μM to 0.93 μM^[1].
IWP-4 (1 μM; 24 h) antagonizes the protective effect of Ginkgolide B (HY-N0784) on primary rat cortical astrocytes against glutamate-induced injury by reversing Ginkgolide B-mediated regulation of apoptosis-related genes and proteins, as well as glutamate transporter genes and proteins^[2].

Protocol

Cell Assay^[1]

hESC cultures are obtained in mTeSR-1 medium and expanded with daily medium exchange until colonies reach the desired level of conﬂuence (~70% to 80%). At this time (marked day 0), mTeSR-1 is replaced with a basal medium comprised of RPMI 1640 medium supplemented with 2% B27 supplement and 1% penicillin/streptomycin. 20 ng/mL BMP-4 and/or 6 ng/mL activin A are added to the basal medium for primitive streak induction, and exchanged daily until day 3. Then, basal media with or without 5 mM IWP-4 is added to the cells and exchanged every 2 days [dimethyl sulfoxide (DMSO) at the same concentration is used as a vehicle control] until day 15, after which basal medium is supplied every 2 days^[1].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
