| Description | Sulindac sulfide (cis-Sulindac sulfide) is a non-steroidal anti-inflammatory compound that has a high affinity for COX-1 and acts as an inhibitor in Ras activation of Raf-1. Sulindac sulfide is a non-competitive inhibitor of gamma-secretase with an IC50 value of 20.2 μM. It is an active metabolite of sulinic acid. |
| Targets&IC50 | γ42-secretase:20.2 μM , γ42-secretase:20.2 μM, COX-1:1.9 µM, COX-2:1.21 µM, Aldose reductase:279 nM |
| In vitro | Treatment with 100 μM of Sulindac sulfide (SSide) induces apoptosis leading to significant reduction in Aβ generation and total protein expression. The IC50 for Aβ42 secretion of SSide is 30.6±2.8 μM. SSide inhibits γ42-secretase activity dose-dependently, with an IC50 of 20.2±2.6 μM. Increasing SSide concentration decreases the slope in the rate vs. enzyme concentration plot, indicating SSide is not an irreversible or pseudo-irreversible inhibitor. After pretreatment of the dialyzed solubilized γ-secretase fraction with SSide and subsequent exposure to CHAPSO buffer without SSide, γ-secretase activity almost fully recovers. This strongly suggests that SSide targets the γ-secretase complex as a reversible inhibitor. [1] |
| In vivo | Sulindac sulfide also inhibits aldose reductase, blocking NADPH-dependent reduction of glucose to sorbitol, and reducing type 2 diabetic complications.[2] Sulindac sulfide inhibits colorectal cancer growth both in vitro and in vivo.[5] |
