Tinuvin 770 [bis(2,2,6,6-tetramethyl-4-piperidinyl)sebacate] is a pharmacologically active agent used worldwide as a light stabilizer for plastic materials. In vitro studies show that it is an L-type Ca(2+) channel and neuronal nicotic acethylcholine receptor...

Neurosci. Lett. 278(3) , 165-8, (2000)

We have investigated the acute effects of systemic administration of Tinuvin 123 on nigro-striatal dopaminergic neurons in the C57Bl/6 mouse. Tinuvin 123 was administered subcutaneously (s.c.) twice, 16 h apart, at doses of 0, 2, 20 or 200 mg/kg body weight t...

Tinuvin 770 [bis(2,2,6,6-tetramethyl-4-piperidinyl) sebacate], is a UV light stabilizer plastic additive used worldwide. It is a component of many plastic materials used in medical and food industries. Earlier studies demonstrated its in vitro L-type Ca2+ cha...

Proc. Natl. Acad. Sci. U. S. A. 90(20) , 9523-7, (1993)

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 microgram...

Free Radic. Biol. Med. 33(1) , 128-36, (2002)

Derivatives of tetramethylpiperidines are extensively employed in polymers to prevent photooxidation, and their stabilizing effect is attributed to the activity of the nitroxide radical derived from the parent amine. In this study, we examined the photoprotec...
