The modulation of membrane structure and stability by dimethyl sulphoxide
28 mg of neutral red powder in 1 mL of dimethyl sulphoxide
Although both oral dimethyl sulphoxide
and oral etretinate have shown promising results, recent case reports have found them to be ineffective.
Historically, dimethyl sulphoxide
was used to control pruritus; however, it helps only a minority of patients and, contrary to early beliefs, it does not have amyloid-dissolving properties (11, 12).
Only few reports are available about the kinetics and mechanism of oxidation of sulphoxide
with chromium(VI) complexes.
The third protocol used methods described by Liebermann and Tucker (2002) which included 20% EG and 20% dimethyl sulphoxide
as the cryoprotectants.
The etherification system recently developed by Nakano's group at Toyko University, employing finely powdered sodium hydroxide as base in dimethyl sulphoxide
, was used by:
5 L,Chloroform AR grade 500ml ,Diethyl Ether AR 500ml,Dimethyl sulphoxide
HPLC 1L ,Ethyl Acetate AR 2.
2-Methoxy-1,4-naphthoquinone (MNQ) (98% pure) and dimethyl sulphoxide
(DMSO) were purchased from Sigma-Aldrich (St.
(DMSO), sodium hydroxide (NaOH) and other chemicals were analytical grade.
Acetic acid glacial, dimethyl sulphoxide
, FolinCiocalteau reagent, hexane, methanol, sodium acetate and sodium carbonate were purchased from Merck.
