Ultrahigh-throughput screening enables efficient single-round oxidase remodelling

Biocatalysis provides a potentially sustainable means of chemical manufacturing. However, the tailoring of enzymes to industrial processes is often laborious and time consuming, which limits the broad implementation of this approach. High-throughput screening methods can expedite the search for suitable catalysts, but are often constrained by the need for labelled substrates. The generalization of such techniques would therefore significantly expand their impact. Here we have established a versatile ultrahigh-throughput microfluidic assay that enables isolation of functional oxidases from libraries that contain up to 107 members. The increased throughput over prevalent methods led to complete active-site remodelling of cyclohexylamine oxidase in one round of directed evolution. A 960-fold increase in catalytic efficiency afforded an enzyme with wild-type levels of activity for a non-natural substrate, allowing biocatalytic synthesis of a sterically demanding pharmaceutical intermediate with complete stereocontrol. The coupled enzyme assay is label free and can be easily adapted to re-engineer any oxidase.

Cationic Polycarbazole Networks as Visible-Light Heterogeneous Photocatalysts for Oxidative Organic Transformations

Photoredox catalysis has aroused great interest from chemists, as it offers a powerful tool for organic synthesis. Cationic polycarbazole networks (CPOP-28 and CPOP-29) were prepared via simple oxidative coupling reaction and applied as heterogeneous photocatalysts for a wide range of oxidative organic transformations, including oxidation of sulfides, hydroxylation of arylboronic acids, and cross-dehydrogenative coupling reactions, in the presence of visible light and air. Remarkably, photocatalytic activities are enhanced by ingenious introduction of trifluoromethyl groups to the polymeric network CPOP-29. The effects of the trifluoromethyl group on photocatalytic activities were elucidated in terms of photophysical and electrochemical properties. The appealing photocatalytic performance of the trifluoromethylated polymer is ascribed to superior light-absorption ability, longer fluorescence lifetime, and stronger oxidative capability. In addition, the photocatalysts showed good recyclability and could be reused after a simple separation workup.

Iron-catalyzed oxidative mono- And bis-phosphonation of N,N-dialkylanilines

The dehydrogenative a-phosphonation of substituted N,N-dialkylanilines by dialkyl H-phosphonates was achieved under mild conditions by using environmentally benign iron(II) chloride as catalyst and teri-butyl hydroperoxide as oxidant. The reaction proceeded in the presence of electron-donating (methoxy, methyl, benzyl) and electron-withdrawing ring-substitutents (bromo, carbonyl, carboxyl, m-nitro) in moderate to good yields. The X-ray crystal structure of N-(5,5-dimethyl-2-oxo- 2lambda5-[1,3,2]dioxaphosphinan-2-yl-methyl)-N-methyl-p-toluidine was determined. Bis-(4-(dimethylamino)phe- nyl)methane and bis-4,4′- (dimethylamino)benzophenone underwent bisphosphonation selectively by respective monophosphonation at the remote dimethylamino groups. Furthermore, the use of excess dialkyl H-phosphonate and oxidant allowed us to functionalize both methyl groups of N(CH3)2 in N,N-dimethyl-p-toluidine and N,N-dimethylaminomesidine, respectively, to obtain alpha,alpha?- bisphosphonatoamines in high yield.

Effects of a 3-alkyl-, 4-hydroxy- and/or 8-aromatic-substituent on the phenylethanolamine N-methyltransferase inhibitor potency and alpha2-adrenoceptor affinity of 2,3,4,5-tetrahydro-1H-2-benzazepines

2,3,4,5-Tetrahydro-1H-2-benzazepine (THBA; 1) is nearly 100-fold more selective an inhibitor of phenylethanolamine N-methyltransferase (PNMT, EC 2.1.1.28) versus the alpha2-adrenoceptor than is 1,2,3,4-tetrahydroisoquinoline (THIQ; 2) (1: PNMT Ki = 3.3 muM, alpha2-adrenoceptor Ki = 11 muM, selectivity [alpha2 Ki/PNMT Ki] = 3.3; 2: PNMT Ki = 9.7 muM, alpha2 Ki = 0.35 muM, selectivity = 0.036;). Since the PNMT inhibitory activity and selectivity of THIQ were enhanced by the introduction of a hydrophilic electron-withdrawing 7-substituent and a 3-alkyl-substituent, a similar study was conducted on THBA. 8-Nitro-THBA (3) was found to be as potent an inhibitor of PNMT as its THIQ analogue (21) and to be more selective due to its reduced alpha2-adrenoceptor affinity (3: PNMT Ki = 0.39 muM, alpha2 Ki = 66 muM, selectivity = 170; 21: PNMT Ki = 0.41 muM, alpha2 Ki = 4.3 muM, selectivity = 10). Introduction of a 3-alkyl substituent on the THBA nucleus decreased both the alpha2-adrenoceptor affinity and the PNMT inhibitory activity, suggesting an area of steric bulk intolerance at both sites. 4-Hydroxy-THBA (15), which can be considered a conformationally-restricted analogue of 3-hydroxymethyl-THIQ (30), exhibited poorer PNMT inhibitory activity and less selectivity than 30 (15: PNMT Ki = 58 muM, alpha2 Ki = 100 muM, selectivity = 1.7; 30: PNMT Ki = 1.1 muM, alpha2 Ki = 6.6 muM, selectivity = 6.0). While the addition of an 8-nitro group to 15 increased the selectivity of 16 as compared to its THIQ analogue (31), it was not as potent at PNMT nor as selective as 8-nitro-THBA (3) (16, PNMT Ki = 5.3 muM, alpha2 Ki = 680 muM, selectivity = 130; 31: PNMT Ki = 0.29 muM, alpha2 Ki = 19 muM, selectivity = 66). Compound 3 is the most selective (PNMT/alpha2) and one of the more potent at PNMT compounds yet reported in the benzazepine series, and should have sufficient lipophilicity to penetrate the blood-brain barrier (CLogP = 1.8).

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 17680-55-6 is helpful to your research. Synthetic Route of 17680-55-6
