    Abstract: Use of 2-pentanone and specific receptor thereof in a manufacture of a product regulating a cell function, a regulation of cell function, a manufacture of a product promoting an increase in an intracellular calcium ion concentration, or a manufacture of a product promoting an increase in a neuronal firing rate is provided. In the present disclosure, the specific receptor of 2-pentanone is expressed in cultured cells or animals, and its specific binding to 2-pentanone opens ligand-gated cation channels, resulting in an increase of intracellular calcium ion concentration, depolarization of cell membranes, and generation of electrical activity or endocrine activity, thereby finally achieving precise regulation of tissue cells and organ functions. After being treated, cells can be activated rapidly, producing effects with a rapid onset; once the treatment is stopped, the experimental effect can be quickly terminated to allow the cells to return to their original state quickly.

    Abstract: Basic mixed oxides useful for base catalyzed reactions such as the aldol condensation of acetone and also useful as catalyst supports are made by mixing an acid such as nitric acid or acetic acid with a pseudob oehmite to form a gel, adding magnesium oxide or hydroxide, in a ratio of magnesium to aluminum of about 1:1 to about 10:1, agitating and heating for about 1 to 24 hours, and subsequently drying and calcining. The resulting polymorphic magnesium-aluminum oxide composition is highly effective in the aldol condensation of acetone to isophorone, and other base catalyzed reactions such as isomerization of olefins, aldol condensation of aldehydes.
