N-[O-1,2,3-benzotriazin-4(3H)one-yl]-3,(2-pyridyldithio)propionate: A more reactive alternative to SPDP
摘要:
N-[O-1,2,3-Benzotriazin-4(3H)one-yl]-3-(2-pyridyldithio)propionate [BPDP] has been synthesized and found to react with secondary amines to give high yields of acylated product. In sharp contrast, the widely used heterobifunctional coupling reagent, N-[O-succinimdyl]-3-(2-pyridyldithio) propionate [SPDP] afforded low to negligible yields of product.

liquid‐disordered bilayers can be much stronger than the attractive forcesbetween this same sterol and an exchangeable mimic of a high‐melting phospholipid in liquid‐ordered bilayers. We conclude that polyunsaturated phospholipids have been largely overlooked as major players in lipid raft formation. This knowledge should stimulate considerable interest in controlling the levels of polyunsaturated phospholipids

Nearest-neighbor recognition (NNR) measurements have been made for two lipidated forms of GlyCys, interacting with analogues of cholesterol and 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC) in the liquid-ordered (l(o)) and liquid-disordered (l(d)) phases. Interaction free energies that have been determined from these measurements have been used in Monte Carlo simulations to quantify the distribution of the peptides between liquid-ordered and liquid-disordered regions. These simulations have shown that significant differences in the lipid chains have a very weak influence on the partitioning of the peptide between these two phases. They have also revealed an insensitivity of the peptide partition coefficient, K-p, to the size of the l(o) and l(d) domains that are present. In a broader context, these findings strongly suggest that the sorting of peripheral proteins in cellular membranes via differential lipidation may be more subtle than previously thought.
