TriDAP
Based on 1 publication(s) in Google Scholar
TriDAP (L-Ala-γ-D-Glu-meso-diaminopimelic acid) is a NOD1 agonist with a Kd value of 34.5 μM. TriDAP enhances the binding of NOD1-RICK, promotes RICK phosphorylation, and activates the NF-κB, TAK1, MEK/ERK, p38 and interferon response pathways. TriDAP downregulates Runx2 via increasing ubiquitination and reduces trabecular bone parameters. TriDAP decreases IκBα levels and increases p65 levels. TriDAP induces the secretion of proinflammatory mediators IL-8 and prostaglandins, triggers tissue inflammation and innate immune activation, and inhibits SARS-CoV-2 replication in lung epithelial cells. TriDAP increases the RANKL/OPG ratio in mice, reduces bone mass and enhances osteoclast activity, and inhibits new bone formation by decreasing the mineralization deposition rate in mice. TriDAP can be used in research related to pulpitis, chronic ulcerative colitis, Crohn's disease and SARS-CoV-2 infection.

TriDAP (0-10 μg/mL; 6 days) dose-dependently inhibits osteogenic differentiation of primary mouse calvarial osteoblast precursors and enhances osteoclast differentiation in the co-culture system of mouse BMMs and primary calvarial osteoblast precursors[1].
TriDAP (0-10 μg/mL; 2 days) downregulates the expression of osteogenic marker genes including Alp, Bsp and Runx2 in MC3T3-E1 mouse preosteoblasts in a dose-dependent manner[1].
TriDAP (0-10 μg/mL; 18 h) dose-dependently inhibits the transcriptional activity of Runx2 in MC3T3-E1 mouse preosteoblasts[1].
TriDAP (1 μg/mL; 2-24 h) reduces the stability of Runx2 protein in transiently transfected HEK293 cells. After 8 hours of co-incubation with Cycloheximide (HY-12320), the relative level of Runx2 decreases by approximately 50%, which enhances Smurf1-mediated Runx2 degradation in cells[1].
TriDAP (1-10 μg/mL; 24 h) increases the ubiquitination level of Runx2 in transiently transfected HEK293 cells in a dose-dependent manner[1].
TriDAP (0.1-10 μg/mL; 2 days) dose-dependently increases the RANKL/OPG ratio in primary mouse calvarial osteoprogenitor cells, through a mechanism that decreases OPG secretion and increases RANKL secretion[1].
TriDAP (1 μg/mL; 15-90 min) activates the NF-κB pathway in MC3T3-E1 mouse osteoprogenitor cells by reducing IκBα levels and increasing p65 levels, and induces nuclear translocation of NF-κB p65[1].
TriDAP (0.1-10 μg/mL; 24 h) dose-dependently enhances the transcriptional activity of NF-κB in MC3T3-E1 mouse preosteoblasts[1].
TriDAP (10 μg/mL; 10 days) inhibits osteogenic mineralization of wild-type primary mouse calvarial preosteoblasts, but this effect is abolished in NOD1-deficient preosteoblasts, indicating that this action is dependent on NOD1[1].
TriDAP (10 μg/mL; 16 h) preferentially activates the transcriptional activity of NF-κB in HEK293 cells transfected with NOD1, whereas the activity is extremely low in cells transfected with NOD2[1].
TriDAP (10-100 μM) binds directly to purified full-length NOD1 protein, with a measured Kd value of 34.5 μM via SPR[4].
Binding of TriDAP (0.1 mM) to purified full-length NOD1 protein increases the binding affinity between purified RICK protein and NOD1, with SPR assays showing that its Kd value decreases from 4.13 μM to 3.26 μM[4].
TriDAP (0-5 mM; 1-4 h) induces the expression of NOD1 and secretion of IL-8 in Caco2-BBE intestinal epithelial cells, and this pro-inflammatory response depends on the expression of NOD1[4].
TriDAP activates the NOD1 pathway in HEK-Blue hNOD1 cells, with an EC50 of 700 ng/mL[5].
TriDAP (0.4-50 µM; 6-24 h) increases the proportion of IL-8+ human lung epithelial A549 cells by 3.29-fold, elevates the proportion of IL-8+ human lung epithelial A549-Dual cells, does not reduce cell viability, and activates the NF-κB and ISRE pathways in human lung epithelial A549-Dual cells[5].
TriDAP (50 µM; 8 h) upregulates the mRNA expression levels of IL-8, CXCL10 and ISG15 in the human lung epithelial cell line A549-Dual[5].
TriDAP (2-50 µM; 3-hour pretreatment; 48 hours post-infection) dose-dependently inhibits SARS-CoV-2 replication in human lung epithelial A549-Dual cells, with an EC50 of 7.75 µM, and reduces the number of infected cells by 49% at a concentration of 50 µM[5].
