- Fabrication of ω-Transaminase@Metal-Organic Framework Biocomposites for Efficiently Synthesizing Benzylamines and Pyridylmethylamines
-
In this study, ten ω-transaminases (ω-TAs) have been investigated to efficiently catalyze the synthesis of twenty-four functionalized benzylamines and pyridylmethylamines. We optimized the reactions, screened suitable amino donors and compared ω-transaminases activities for all aromatic aldehyde substrates. Under the optimized conditions, eighteen aromatic amines have been obtained with 60.4%–96.6% conversions and isolated only via simple extraction and recrystallization with 18.5%–81% yields on a preparative scale. Furthermore, we first immobilized the Bm-STA onto the MOFs via the physical adsorption to overcome the limitation of free enzyme and improve their industrial applications. The obtained Bm-STA/UiO-66-NH2 composites exhibited not only high enzymes loading (80.4 mg g?1) and enzyme activity recovery (95.8%), but also the better reusability, storage stability, pH stability and the tolerance to acetone and DMF.

- COMPOSITIONS AND METHODS FOR THE TREATMENT OF METABOLIC DISORDERS
-
The invention relates to the compounds of formula I or its pharmaceutical acceptable salts, as well as polymorphs, solvates, enantiomers, stereoisomers and hydrates thereof. The pharmaceutical compositions comprising an effective amount of compounds of formula I, and methods for treating or preventing metabolic disorders may be formulated for oral, buccal, rectal, topical, transdermal, transmucosal, intravenous, parenteral administration, syrup, or injection. Such compositions may be also used to the treatment of diabetes, lipid peroxidation, hypertriglyceridemia, metabolic disorders, free radical generated due to reactive oxygen and carbonyl groups, ionizing radiation, advanced glycation end products, kidney disease, renal complications and kidney stone disease.
