Application of host-guest chemistry in nanotube-based device fabrication: Photochemically controlled immobilization of azobenzene nanotubes on patterned α-CD monolayer/Au substrates via molecular recognition
Banerjee, Ipsita A.,Yu, Lingtao,Matsui, Hiroshi
, p. 9542 - 9543 (2003)
Azobenzene-functionalized nanotubes recognized and attached onto well-defined complementary regions of thiolated α-CD SAM/Au substrates via host-guest molecular recognition. The binding between the azobenzene nanotubes and the α-CD SAM/Au substrates was c

Hepatitis C virus (HCV) entry is a key target for the treatment of chronic HCV infection. In our continuing efforts to identify novel potential anti-HCV entry inhibitors, a series of water-soluble triazole-bridged α-cyclodextrin-pentacyclic triterpene conjugates were easily synthesized with moderate to good yields. These novel compounds were fully identified and characterized by 1D and 2D NMR spectroscopy and ESI-HRMS. The anti-HCV entry activities were determined based on HCVpp/VSVGpp entry assays. The best results were found for compounds 15 and 18, which displayed the most promising anti-HCV entry activities with average IC50values of 1.18?μM and 0.25?μM, respectively. In addition, the in?vitro cytotoxicity activity of the two compounds against MDCK cells showed no toxicity at 100?μM. Five different binding assays were set up to identify the action mechanism. The results showed that the compounds exert their inhibitory activity at the post-binding step and subsequently prevent virus entry.
CONVENIENT PREPARATION AND EFFECTIVE SEPARATION OF THE C-2 AND C-3 TOSYLATES OF α-CYCLODEXTRIN
Fujita, Kahee,Nagamura, Satoru,Imoto, Taiji
, p. 5673 - 5676 (1984)
Secondary tosylates of α-cyclodextrin were conveniently prepared by the reaction of the cyclodextrin with tosyl chloride in alkaline water where pH of the mixture should be allowed to decrease as the proceeding of reaction, and were effectivelly separated by reversed-phase column chromatography.
Unraveling unidirectional threading of α-cyclodextrin in a [2]rotaxane through spin labeling approach
Casati, Costanza,Franchi, Paola,Pievo, Roberta,Mezzina, Elisabetta,Lucarini, Marco
, p. 19108 - 19117 (2012)
We present here the results of a CW-ESR investigation of a double spin labeled α-cyclodextrin-based [2]rotaxane that is characterized by the presence of nitroxide labels both at the wheel and at the dumbbell. This was accomplished by synthesizing a spin l
MONOTOSYLATED α-AND β-CYCLODEXTRINS PREPARED IN AN ALKALINE AQUEOUS SOLUTION
Takahashi, Keiko,Hattori, Kenjiro,Toda, Fujio
, p. 3331 - 3334 (1984)
In order to establish the tosylated positions of α- and β-cyclodextrins, 13C-nmr spectra for the monotosyl-derivatives prepared in an alkaline aqueous solution were examined and determined to be in the 6-position of one glucose unit for β-cyclodextrin and
