Synthesis of a quaternary polyprenyl ammonium salt.
Reaction of primary C(55)-allylic alcohol moraprenol (WT(3)C(7-9)-OH, a polyprenol from mulberry leaves) with triethylamine in the presence of phosphorus oxychloride leads to a quaternary ammonium chloride with a good yield (72%) and high cis-stereoselectivity of the terminal isoprene unit. Cationic polyprenyl derivatives may be useful for transfection and immunological studies.
متن کاملSynthesis, Characterization, and Bioactivity of Rosin Quaternary Ammonium Salt Derivatives
Two series of rosin quaternary ammonium salts (QAS) were synthesized using the same path. The structure of the target products was characterized by HPLC, MS, IR, and 1 HNMR, and the bioactivity was determined by filter paper method using Trametes versicolor (white-rot fungus) and Gloeophyllum trabeum (brown-rot fungus), which are two kinds of general wood decay fungi in nature. The results show...
متن کاملMutagenic activity of quaternary ammonium salt derivatives of carbohydrates
This paper presents a study on a series of quaternary ammonium salt (QAS) derivatives of glucopyranosides with an elongated hydrophobic hydrocarbon chain. The new N-[6-(β-D-glucopyranosyloxy)hexyl]ammonium bromides and their O-acetyl derivatives were analyzed via (1)H and (13)C NMR spectroscopy. The mutagenic activity of the newly synthesized QAS was investigated using two different techniques:...

متن کاملEvaluation of a silane quaternary ammonium salt as an antimicrobial surface treatment.
NASA guidelines for planetary protection aim to preserve the unaltered environments of both our own planet and all other planetary bodies in our solar system. Preventing the spread of Earth-based life forms to other planets and the contamination of our own planet by extraterrestrial life forms is an important consideration when planning space missions. Even with extensive sterilization techniqu...
