Cou-Coxib

Cou-Coxib is a ROS-responsive fluorescent Celecoxib (HY-14398) prodrug that is activated by ROS triggering and self-immolation to release Celecoxib and the fluorophore Cou-OH. Celecoxib released from Cou-Coxib elevates intracellular ROS levels, induces S-phase arrest in MDA-MB-231 triple-negative breast cancer cells, and downregulates the expression of apoptosis-related proteins Bcl2, Survivin, and procaspase-3. In the H9C2 cardiomyoblast model, Cou-Coxib attenuates the cardiotoxicity caused by Celecoxib, maintains mitochondrial membrane potential, upregulates IL-10, and exhibits biocompatibility in developing zebrafish embryos. Cou-Coxib can be used for research on triple-negative breast cancer.

Oxidative Stress

Cou-Coxib is activated by H₂O₂ in PBS, releasing Cou-OH with turn-on fluorescence at 453 nm, reaching saturation at 180 min and approximately 400 μM H₂O₂^[1].

Others

Cou-Coxib (100 μM) and H₂O₂ (4 mM) released 72% Celecoxib (HY-14398) and 69% Cou-OH within 4 h in PBS, with 50% release at 14 min and 36 min, respectively^[1].
Cou-Coxib (30 μM) has a log P of 3.68^[1].

Anti-cancer

Cou-Coxib was most effective in MDA-MB-231 and MCF-7 breast cancer cells, with IC₅₀ values of 134.6 and 151.6 μM after 48 h^[1].

Oxidative Stress

Anti-cancer

Cou-Coxib (150-200 μM; 12 h) induces intracellular ROS in MDA-MB-231 cells^[1].
Cou-Coxib (25 μM; 5 h) was taken up by MDA-MB-231 cells and activated by endogenous ROS to produce blue fluorescence, and pre-incubation with NAC (HY-B0215) reduced this fluorescence^[1].

Cell Cycle Regulation

Anti-cancer

Cou-Coxib (150-200 μM; 48 h) arrested MDA-MB-231 cells in the S phase; downregulated procaspase 3, Bcl2, survivin, and p53^[1].

Apoptosis

Cou-Coxib (150-200 μM; 48 h) induced less apoptosis in H9C2 cells than free Celecoxib, indicating reduced cardiotoxicity^[1].

Oxidative Stress

Mitochondrial Function

Cou-Coxib (150 μM; 12 h) induced nominal ROS in H9C2 cells without disrupting the mitochondrial membrane potential^[1].

Innate Immunity

Cytokines & Chemokines

Cou-Coxib (150-200 μM; 48 h) does not induce COX-2 and upregulates IL-10 in H9C2 cells^[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.
