Snail IN-1
Based on 1 Customer Validation
Snail IN-1 is an orally active Snail inhibitor with a Ka of 0.36 μM.Snail IN-1 disrupts Snail-CBP interaction, accelerates Snail protein degradation, reduces Snail acetylation, increases Snail polyubiquitination, and selectively downregulates Snail protein without altering other EMT transcription factors.Snail IN-1 reduces atherosclerotic plaque burden, modulates inflammation and plaque stability factors, downregulates CCL5, CXCL10, MMP2, and MMP9, and upregulates α-smooth muscle actin.Snail IN-1 exerts anti-inflammatory and plaque-stabilizing properties.Snail IN-1 can be used for the research of atherosclerosis.

Recombinant Snail Protein 0.36 μM (Ki) |
Snail IN-1 (compound S29) (0.1-10 μM; 48 h) potently downregulates the protein level of Snail in HUVECs in a concentration-dependent manner in vitro without altering the mRNA level of Snail, suggesting that its regulatory effect occurs at the post-transcriptional stage[1].
Snail IN-1 (5-60 μM; 48 h) shows no significant cytotoxicity against HUVECs even at concentrations up to 60 μM after 48 h of incubation[1].
Snail IN-1 (5 μM; 0-240 min) accelerates the degradation of Snail protein and reduces its stability in HUVECs[1].
Snail IN-1 (2.5-20 μM; 48 h) specifically downregulates the protein level of Snail in HUVECs, without affecting the protein or mRNA levels of other EMT transcription factors (Zeb1, Slug, Twist)[1].
Snail IN-1 (5 μM; 24 h) promotes Snail degradation by disrupting the interaction between Snail and CBP, reducing the acetylation level of Snail, and increasing the polyubiquitination of Snail in human umbilical vein endothelial cells (HUVECs)[1].
Snail IN-1 (2.5 μM; 24 h) significantly downregulates the mRNA levels of pro-atherosclerotic factors (CCL5, CXCL10, MMP-9, MMP-2) in TNF-α-stimulated HUVECs[1].
Snail IN-1 (1.25-5 μM; 24 h) inhibits the expression of CCL5 and CXCL10 proteins in TNF-α-stimulated HUVEC in a concentration-dependent manner[1].
Snail IN-1 (2.5 μM; 24 h) impairs monocyte recruitment by altering the secretory profile of TNF-α-stimulated HUVEC[1].
