Although the exact mechanism of action is unknown, pregabalin selectively binds to alpha2delta (A2D) subunits of presynaptic voltage-dependent calcium channels (VDCCs) located in the central nervous system (CNS).
Hexane /ËhÉkseÉªn/ is an alkane of six carbon atoms, with the chemical formula C 6 H 14. typical laboratory use of hexanes is to extract oil and grease contaminants from water and soil for analysis. Since hexane cannot be easily deprotonated, it is used in the laboratory for reactions that involve very strong bases, such as the preparation of organolithiums.
* Appearance and odor. N-hexane is a colorless, volatile liquid with a mild, gasoline-like odor. Commercial n-hexane is a mixture of n-hexane isomers with a small amount of cyclopentane, pentane, and heptane isomers. Benzene may be present in concentrations ranging from one to six percent.
