  2. Transition metal complexes of 1,10-phenanthroline - Wikipedia

    en.wikipedia.org/wiki/Transition_metal_complexes...

    1,10-Phenanthroline is an inhibitor of metallopeptidases, with one of the first observed instances reported in carboxypeptidase A. [11] Inhibition of the enzyme occurs by removal and chelation of the metal ion required for catalytic activity, leaving an inactive apoenzyme . 1,10-Phenanthroline targets mainly zinc metallopeptidases, with a much ...

  6. Tetramethylbutane - Wikipedia

    en.wikipedia.org/wiki/Tetramethylbutane

    Tetramethylbutane, sometimes called hexamethylethane, is a hydrocarbon with formula C 8 H 18 or (H 3 C-) 3 C-C(-CH 3) 3. It is the most heavily branched and most compact of the octane isomers, the only one with a butane (C4) backbone. Because of its highly symmetrical structure, it has a very high melting point and a short liquid range; in fact ...

  7. Tetramethylethylene - Wikipedia

    en.wikipedia.org/wiki/Tetramethyllead

    The recommended time-weighted average exposure limit to tetramethyllead is 0.075 milligrams per cubic meter during a 10-hour workday; the OSHA permissible exposure limit is the same value assuming an 8-hour workday. Exposure to tetramethyllead can affect the central nervous system, the kidneys, and the cardiovascular system.

  9. Tetramethylbenzene - Wikipedia

    en.wikipedia.org/wiki/Tetramethylbenzene

    The tetramethylbenzenes constitute a group of substances of aromatic hydrocarbons, which structure consists of a benzene ring with four methyl groups (–CH 3) as a substituent. [1] Through their different arrangement, they form three structural isomers with the molecular formula C 10 H 14. They also belong to the group of C 4-benzenes.
