A new class of sulfoxide surfactants derived from Tris. Synthesis and preliminary assessments of their properties
摘要:
A new class of non-ionic amphiphilic molecules suitable for biological purposes, especially extraction of membrane proteins, is reported. Such surfactants were prepared in two steps : addition of alkyl or fluoroalkyl mercaptan on Tris(hydroxymethyl)acrylamidomethane (THAM) derivatives, followed by the oxydation of sulfide group in sulfoxide moiety in order to provide water solubility to the molecule. The detergent efficiency of these new surfactants were assayed on rat liver cells. (C) 1998 Elsevier Science Ltd. All nights reserved.

Compound according to formula
wherein
R is a linear or branched alkyl radical, optionally substituted having from 2 to 40 C-atoms; R1, R2, and R3 are the same or different and selected from lower alkyl; and R4, R5, and R6 are the same or different and selected from hydrogen, halogen or an alkali metal or alkali earth metal.
The compound shows interesting surface active properties and a low toxicity profile, and is suitable for cosmetic, detergent and agricultural compositions.

A new class of amphiphilic molecules suitable for biological purposes, especially extraction of membrane proteins and/or glycoproteins, is reported. These compounds were prepared by telomerization of a Tris-(Hydroxymethyl)-acrylamidomethane monomeric unit in the presence of an alkyl thiol as transfer reagent and of α,α′-(azobis)-isobutyronitrile (AIBN) as initiator. These compounds show similar or
