In 2015,PLoS One included an article by Sarkar, Sourav; Pires, Marcos M.. Application In Synthesis of (R)-7-Hydroxy-1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid. The article was titled 《D-Amino acids do not inhibit biofilm formation in Staphylococcus aureus》. The information in the text is summarized as follows:
Bacteria can either exist in the planktonic (free floating) state or in the biofilm (encased within an organic framework) state. Bacteria biofilms cause industrial concerns and medical complications and there has been a great deal of interest in the discovery of small mol. agents that can inhibit the formation of biofilms or disperse existing structures. Herein it was shown that, contrary to previously published reports, D-amino acids do not inhibit biofilm formation of Bacillus subtilis (B. subtilis), Staphylococcus aureus (S. aureus), and Staphylococcus epidermis (S. epidermis) at millimolar concentrations The authors evaluated a diverse set of natural and unnatural D-amino acids and observed no activity from these compounds in inhibiting biofilm formation. In the experimental materials used by the author, we found (R)-7-Hydroxy-1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid(cas: 152286-30-1Application In Synthesis of (R)-7-Hydroxy-1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid)
(R)-7-Hydroxy-1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid(cas: 152286-30-1) belongs to tetrahydroisoquinoline. Tetrahydroisoquinoline Reactions: As a secondary amine, tetrahydroisoquinoline has weakly basic properties and forms salts with strong acids.Application In Synthesis of (R)-7-Hydroxy-1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid It can be dehydrogenated to give isoquinoline and hydrogenated to decahydroisoquinoline. Like other secondary amines, tetrahydroisoquinoline can be oxidized to the corresponding nitrone using hydrogen peroxide, catalyzed by selenium dioxide.
