  A new procedure for the conversion of thiols into reactive sulfenylating agents

  摘要：

  Thiols may be converted in high yield into unsymmetrical 2-pyridyl disulfides 3. Treatment of these with alkylating agents (e.g., alkyl fluorosulfonates or oxonium salts) affords the corresponding N-alkylpyridyl disulfides 4, which are potent sulfenylating agents (Scheme II) and react smoothly with a variety of sulfur nucleophiles (e.g., thiols, thiones, thioamides, dithiocarbamates, thiocyanate, etc.) to afford disulfides, with amines to afford sulfenamides, and with beta-diketones to afford sulfides. This new method is particularly well-suited to the preparation of unsymmetrical disulfides and sulfenamides from complex and otherwise reactive thiols.

• Effect of the Nature of the Spacer on Gene Transfer Efficacies of Novel Thiocholesterol Derived Gemini Lipids in Different Cell Lines: A Structure–Activity Investigation
  作者：Avinash Bajaj、Paturu Kondaiah、Santanu Bhattacharya

  DOI：10.1021/jm7010436

  日期：2008.4.1

  A structure-activity investigation was undertaken to see the effect of the nature of the spacer on the gene transfection efficacies of thiocholesterol -derived cationic gemini lipids possessing disulfide linkage between the cationic headgroup and the thiocholesterol moiety. Three gemini cationic lipids possessing hydrophobic flexible (-(CH2)(5)-; 1), hydrophobic rigid (-C6H4-; 2), and hydrophilic flexible (-CH2-CH2-O-CH2-CH2-; 3) spacer segments were synthesized. In HeLa cells, lipid formulations 1 and 2 were found to be more effective as compared to lipid 3 formulation. In HT1080 cell line, the order of transfectability was 3 > 1 > 2. Transfection studies in HeLa and HT 1080 cell line also showed 40-50% transfection efficacy in the presence of 10% serum conditions. These formulations were also able to transfect gene across difficult cells like HaCaT. Cytotoxic studies showed the nontoxic nature of these lipid-DNA complexes at different N/P ratios used for transfection studies.
