1-Dodecylpyridin-1-ium bromide (cas: 104-73-4) belongs to pyridine derivatives. Pyridines are an important class of heterocycles and occur in polysubstituted forms in many naturally occurring biologically active compounds, drug molecules and chiral ligands. Many analogues of pyridine are known where N is replaced by other heteroatoms . Substitution of one C–H in pyridine with a second N gives rise to the diazine heterocycles (C4H4N2), with the names pyridazine, pyrimidine, and pyrazine.Synthetic Route of C17H30BrN

Effects of head group of cationic surfactants on the hydrolysis of p-nitrophenyl acetate catalyzed by α-chymotrypsin was written by Ghosh, Kallol K.;Verma, Santosh Kumar. And the article was included in International Journal of Chemical Kinetics in 2009.Synthetic Route of C17H30BrN This article mentions the following:

The search for activity enhancement (superactivity) has been an important aspect of in vitro micellar enzymol. The present kinetic study was undertaken to investigate the effect of different cationic surfactants which might improve the hydrolytic activity of chymotrypsin (I). Here, the kinetics of hydrolysis of p-nitrophenyl acetate catalyzed by I was studied in the presence of several cationic surfactants having different head groups maintaining the dodecyl hydrophobic residue and bromide counterion. I activity was tested in the presence of dodecyl trimethylammonium bromide (DTAB), dodecylpyridinium bromide (DPB), dodecyldimethylethanolammonium bromide (DDMEAB), dodecyldiethylethanolammonium bromide (DDEEAB), benzyldimethyldodecylammonium bromide (BDDAB), and dodecyltriphenylphosphonium bromide (DTPB) surfactants. The extent of superactivity depended upon the head groups of the surfactants. I activity also depended on the surfactant concentration and it varied with the surfactant head group dimensions (DTPB > DDEEAB > DTAB > BDDAB > DDMEAB > DPB). For all surfactants, DTPB exhibited the highest superactivity. The effects of the surfactants on apparent kinetic parameters such as the Km and kcat were determined In the experiment, the researchers used many compounds, for example, 1-Dodecylpyridin-1-ium bromide (cas: 104-73-4Synthetic Route of C17H30BrN).
