Lysine acylation of proteins is a crucial chem. reaction, both as a post-translational modification and as a method for bioconjugation. We previously developed a chem. catalyst, DSH, which activates a chem. stable thioester including acyl-CoA, allowing the site-selective lysine acylation of histones under physiol. conditions. However, a more active catalyst is required for efficient lysine acylation in more complex biol. milieu, such as in living cells, but there are no rational guidelines for developing efficient lysine acylation catalysts for use under physiol. conditions as opposed to in organic solvents. We, herein, conducted a kinetic anal. of the ability of DSH and several derivatives to mediate lysine acetylation to better understand the structural elements essential for high acetylation activity under physiol. conditions. Interestingly, the obtained trend in reactivity was different from that observed in organic solvents, suggesting that a different principle is necessary for designing chem. catalysts specifically for use under physiol. conditions compared to catalysts for use in organic solvents. Based on the obtained information, we identified a new catalyst scaffold (PQSH) with high activity and structural flexibility for further modification to improve this catalyst system. In the experiment, the researchers used many compounds, for example, (4-Bromopyridin-2-yl)methanol (cas: 131747-45-0HPLC of Formula: 131747-45-0).
(4-Bromopyridin-2-yl)methanol (cas: 131747-45-0) belongs to pyridine derivatives. Pyridine has a conjugated system of six π electrons that are delocalized over the ring. The molecule is planar and, thus, follows the Hückel criteria for aromatic systems. 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.HPLC of Formula: 131747-45-0
