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).

A pharmacologically active agent was easily extracted by aqueous or organic solvents from laboratory plastic tubes (Falcon Blue Max) and has been chemically identified as bis(2,2,6,6-tetramethyl-4-piperidyl) sebacate. This compound (approximately 12 micrograms per tube approximately 25 nmol) blocked 1,4-dihydropyridine-sensitive 45Ca2+

The use-dependent, nicotinic acetylcholine receptor antagonist bis-(2,2,6,6-tetramethyl-4-piperidinyl) sebacate (BTMPS) was studied for its potential to reduce the self-administration of nicotine in rats, as well as to reduce context-induced recidivistic-like behavior after a six-week period of cessation. Rats were allowed to

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

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
