  Enhancement of the thermal and storage stability of urease by covalent attachment to phospholipid-bound silica

  摘要：

  Urease was immobilized directly on silanized silica surfaces carrying alkyl moieties with terminal carboxylic groups. The enzyme was also covalently attached to phospholipid-bound silanized silica surfaces through the terminal carboxyl moiety on the sn-2 acyl chain of the lipid. The surfaces were characterized by X-ray photoelectron spectroscopy and ellipsometry. The activity of the immobilized urease was determined by UV spectrophotometry using a urea/bromocresol purple substrate. The enzymic activity decreases exponentially upon storage under dry solid conditions for 1 week or upon heating to 100-degrees-C in the case of the silane/enzyme surfaces. On the other hand, the enzyme immobilized on Phospholipid-carrying silica surfaces retained its entire original activity under dry storage or heat treatment conditions. Such immobilized urease systems could find extensive applicability In the design of in vivo dialysis equipment or for on-line monitoring of urea.

  one-pot conversion of stable triisopropylsilyl- and tert-butyldimethylsilyl carboxylates to their corresponding acyl- or aroyl isothiocyanates using in-situ generation of Ph3P(SCN)2 at room temperature under neutral condition. This method has also been applied for the high yield preparation of 2-thioxo-3,4-dihydro-2H-1,3-benzoxazine-4-one, which has fungicidal and bactericidal activities.

• EFFECTIVE SILYLATION OF CARBOXYLIC ACIDS UNDER SOLVENT-FREE CONDITIONS WITH <i>tert</i>-BUTYLDIMETHYLSILYL CHLORIDE (TBDMSCL) AND TRIISOPROPYLSILYL CHLORIDE (TIPSCL)

  Various types of carboxylic acids can be converted effectively to their corresponding TBDMS and TIPS esters using TBDMSCI and TIPSCI in the presence of imidazole under solvent-free conditions. The advantage of this modified method in comparison with that reported by Corey is the elimination of DMF, which eliminates aqueous work-up. The method is not a time-consuming process and the reactions proceed spontaneously. By this method, absolute chemoselectivity for the protection of carboxylic acid functions in the presence of 2 degrees, 3 degrees hydroxyl groups are observed.
