General description

Bis(2,2,6,6-tetramethyl-4-piperidyl) (T770) sebacate is a low molecular weight ultra violet (UV) hindered amine light stabilizer (HALS) made up of nitroxyl radicals. It acts as a heat controller that can react with phenolic antioxidants incorporated in polymers.

Application

T770 can be used as a hindered amine UV stabilizer in plastic materials. It can be used in the manufacturing and packaging of pharmaceutical products. Titanium oxide(TiO2)/T770 may be used in amine induced light stabilizers in the synthesis of recyclable water-based polyurethane with poly(oxytetramethylene)glycol (PTMG).

Tinuvin 770 (BTMPS) is a non-competitive, use-dependent antagonist of nicotinic acetylcholine receptors (nAChRs). The drug is highly lipid soluble and as such it has the potential to act within the brain. Presently the ganglionic blocking drug mecamylamine is used almost

In this study, the use-dependent, nicotinic receptor antagonist bis (2,2,6,6-tetramethyl-4-piperidinyl) sebacate (BTMPS) was evaluated for its ability to attenuate the adverse consequences associated with morphine in rats in all three phases of an abstinence model of drug seeking: self-administration, acute

Some noncompetitive inhibitors (e.g., ganglionic blockers) exhibit selectivity for the inhibition of neuronal nicotinic acetylcholine receptors (nAChRs). This study characterizes the mechanism of selective long-term inhibition of neuronal and muscle-neuronal chimeric nAChRs by bis(2,2,6,6-tetramethyl-4-piperidinyl) sebacate (bis-TMP-10 or BTMPS), a bifunctional
