Artificial metalloenzymes, resulting from incorporation of a metal cofactor within a host protein, have received increasing attention in the last decade. The directed evolution is presented of an artificial transfer hydrogenase (ATHase) based on the biotin-streptavidin technology using a straightforward procedure allowing screening in cell-free extracts. Two streptavidin isoforms were yielded with improved catalytic activity and selectivity for the reduction of cyclic imines. The evolved ATHases were stable under biphasic catalytic conditions. The X-ray structure analysis reveals that introducing bulky residues within the active site results in flexibility changes of the cofactor, thus increasing exposure of the metal to the protein surface and leading to a reversal of enantioselectivity. This hypothesis was confirmed by a multiscale approach based mostly on molecular dynamics and protein?ligand dockings.

Chemical Research Letters, May 2021. Research speed reading in 2021. Related Products of 17680-55-6, The transformation of simple hydrocarbons into more complex and valuable products via catalytic C–H bond functionalisation has revolutionised modern synthetic chemistry. 17680-55-6, Name is 7-Bromo-1,2,3,4-tetrahydroisoquinoline, molecular formula is C9H10BrN. In a Article，once mentioned of 17680-55-6

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. Related Products of 17680-55-6

In an article，Which mentioned a new discovery about 3340-78-1

Metal-based surface active ionic liquids (MSAILs), 1-alkyl-3-methyl imidazoliumtetrachloromanganate [Cnmim][MnCl4]2 ? (n= 8,10,12) have been synthesized and characterized for self-assembling behavior in aqueous solution using tensiometry, fluorescence, conductivity, dynamic light scattering (DLS) and transmission electron microscopy (TEM) techniques. MSAILs have exhibited 4 to 5 fold higher surface activity as compared to the non-metal based surface active ionic liquids. MSAILs micellar solutions have been successfully used for C(sp3)-H functionalized oxidative cyanation of the tertiary amines. Oxidative Strecker reaction was carried out with different concentrations of the MSAILs, cyanide source (TMSCN) and substrate, and moderate to very high yields (up to 95%) could be achieved in 3?4 h. Usually, cyanation of tertiary amines is carried out in organic solvents under harsh conditions without recycling of the catalyst. Herein aqueous MSAILs micellar solutions have been used as a solvent, catalyst as well as template with a good recycling ability, thus making the approach simpler, greener, and sustainable.
