Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Article, Research Support, Non-U.S. Gov’t, ACS Biomaterials Science & Engineering called Thromboresistance of Silicones Modified with PEO-Silane Amphiphiles, Author is Ngo, Bryan Khai D.; Barry, Mikayla E.; Lim, Kendrick K.; Johnson, Jessica C.; Luna, David J.; Pandian, Navaneeth K. R.; Jain, Abhishek; Grunlan, Melissa A., which mentions a compound: 14694-95-2, SMILESS is [Rh]Cl.P(C1=CC=CC=C1)(C2=CC=CC=C2)C3=CC=CC=C3.P(C4=CC=CC=C4)(C5=CC=CC=C5)C6=CC=CC=C6.P(C7=CC=CC=C7)(C8=CC=CC=C8)C9=CC=CC=C9, Molecular C54H45ClP3Rh, Safety of Tris(triphenylphosphine)chlororhodium.
The antifouling properties of poly(ethylene oxide) (PEO)-silane amphiphiles as surface-modifying additives (SMAs) in a condensation cure silicone have been previously demonstrated against simple protein solutions Comprising an oligo(dimethylsiloxane) tether (m = 13 or 30) and PEO segment (n = 8), sustained protein resistance was achieved even in the absence of a cross-linkable triethoxysilane group, particularly when comprising the longer tether. To probe their potential for thromboresistance, PEO-silane amphiphile SMAs were used to bulk-modify silicones and evaluated for adhesion resistance against whole human blood under both static and dynamic conditions. Both a crosslinkable (XL diblock, m = 13) and a non-crosslinkable (Diblock, m = 30) SMA were evaluated at various concentrations (5-50μmol SMA/g silicone) in a condensation cure silicone. Under static conditions, silicones modified with either SMA at concentrations of 10μmol/g or greater were effective in reducing adhesion of human fibrinogen and platelets. Dynamic testing further showed that modified silicones were able to reduce protein adsorption and thrombus formation. This occurred at 5 and 10μmol/g for silicones modified with XL diblock, m = 13 and diblock, m = 30 SMAs, resp. Combined, these results indicate the effectiveness of PEO-silane amphiphiles as SMAs in silicone for improved thromboresistance.
Although many compounds look similar to this compound(14694-95-2)Safety of Tris(triphenylphosphine)chlororhodium, numerous studies have shown that this compound(SMILES:[Rh]Cl.P(C1=CC=CC=C1)(C2=CC=CC=C2)C3=CC=CC=C3.P(C4=CC=CC=C4)(C5=CC=CC=C5)C6=CC=CC=C6.P(C7=CC=CC=C7)(C8=CC=CC=C8)C9=CC=CC=C9), has unique advantages.
