| Hazard Information | Back Directory | [Description]
Association of Ras protein with the inner surface of the plasma membrane is required for Ras signaling activity. Farnesyl thiosalicylic acid (FTS) is an inhibitor of Ras-mediated signaling that functions by dislodging Ras from the cell membrane thereby rendering it susceptible to proteolytic degradation.1 FTS inhibits the growth of human Ha-ras-transformed Rat1 fibroblasts with an IC50 value of 7.5 μM.2 It does not inhibit Ras farnesylation in vitro and although FTS does inhibit prenylated protein methyltransferase (PPMTase) in cell-free systems with a Ki value of 2.6 μM, it is relatively ineffective at inhibiting methylation in whole cells.3 Treatment of chow-fed ApoE-deficient mice with 5 mg/kg FTS three times per week for six weeks reduces early atherosclerotic lesion development by 52% compared to controls.4 | [Chemical Properties]
Pale Yellow Solid | [Uses]
Salirasib is a new specific nontoxic drug with a mild hydrophobic nature, which acts as a Ras antagonist and can therefore be used for stent applications as well as for local cancer treatment.
| [Definition]
ChEBI: Salirasib is a sesquiterpenoid. | [Biochem/physiol Actions]
Salirasib (Farnesylthiosalicylic acid) is a RAS inhibitor that acts by dislodging the farnesylated protein from the membrane, facilitating Ras degradation. Salirasib impairs downstream signaling and suppresses growth and migration of proliferating tumor cells in in vitro and in vivo models. Salirasib (Farnesylthiosalicylic acid) has recently been shown to possess significant anti-inflammatory and anti-arthritic properties. | [References]
