Application of 151004-92-1

Optically pure 1,2,3,4-tetrahydroisoquinoline carboxylic acids are important chiral building blocks in the pharmaceutical and fine chemical industries. However, the existing chemo-enzymatic deracemization method employing d-amino acid oxidase from Fusarium solani M-0718 (FsDAAO) suffers from the requirement for a large excess of a nonselective chemical reducing agent. To explore an alternative method, we envisaged a concurrent biocatalytic oxidation and reduction cascade in one pot. Herein, we report a novel biocatalytic route for the asymmetric reduction of 3,4-dihydroisoquinoline-1-carboxylic acids employing Delta1-piperidine-2-carboxylate/Delta1-pyrrolidine-2-carboxylate reductase from Pseudomonas putida KT2440 (PpDpkA) as a biocatalyst, yielding the corresponding (S)-1-carboxyl-substituted tetrahydroisoquinolines with high conversions and enantiomeric excess (>99% ee). By combining FsDAAO and PpDpkA in one pot, a fully biocatalytic method was demonstrated for the deracemization of a range of racemic 1-carboxyl substituted tetrahydroisoquinolines to produce the corresponding (S)-enantiomers with >99% conversions and >99% ee. Furthermore, preparative-scale biotransformation of racemic 1,2,3,4-tetrahydroisoquinoline-1-carboxylic acid gave the (S)-enantiomer with 89% isolated yield and >99% ee. Taken together, we provide an enantioselective biocatalytic redox cascade method for the one-pot synthesis of enantiopure 1,2,3,4-tetrahydroisoquinoline carboxylic acids.

Computed Properties of C10H11NO2, New Advances in Chemical Research, May 2021. Chemistry is the experimental science by definition. We want to make observations to prove hypothesis.

A high-throughput screen (HTS) of the MLPCN library using a homogenous fluorescence polarization assay identified a small molecule as a first-in-class direct inhibitor of Keap1-Nrf2 protein-protein interaction. The HTS hit has three chiral centers; a combination of flash and chiral chromatographic separation demonstrated that Keap1-binding activity resides predominantly in one stereoisomer (SRS)-5 designated as ML334 (LH601A), which is at least 100× more potent than the other stereoisomers. The stereochemistry of the four cis isomers was assigned using X-ray crystallography and confirmed using stereospecific synthesis. (SRS)-5 is functionally active in both an ARE gene reporter assay and an Nrf2 nuclear translocation assay. The stereospecific nature of binding between (SRS)-5 and Keap1 as well as the preliminary but tractable structure-activity relationships support its use as a lead for our ongoing optimization.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 151004-92-1, help many people in the next few years.Computed Properties of C10H11NO2

A dynamic kinetic resolution method for the preparation of enantiopure 1,2,3,4-tetrahydroisoquinoline-1-carboxylic acid (R)-2 was developed involving the CAL-B-catalyzed enantioselective hydrolysis of the corresponding ethyl ester (±)-1 in toluene/acetonitrile (4:1) containing 1 equiv of added water and 0.25 equiv of dipropylamine. This method allowed the preparation of (R)-2 (ee = 96%) with 80% isolated yield. The kinetic resolution of (±)-1 in diisopropyl ether at 3 C afforded both enantiomers with ee ?92%.

Optically pure 1,2,3,4-tetrahydroisoquinoline carboxylic acids constitute an important class of building blocks for the synthesis of natural products and synthetic pharmaceuticals. However, redox deracemization of racemic 1,2,3,4-tetrahydroisoquinoline carboxylic acids as an attractive method is still challenging for the lack of suitable oxidoreductases. Herein, a D-amino acid oxidase from Fusarium solani M-0718 (FsDAAO) with broad substrate scope and excellent enantioselectivity was exploited through genome mining, and applied for the kinetic resolution of a number of racemic 1- and 3-carboxyl substituted tetrahydroisoquinolines to yield the corresponding (S)-enantiomers with excellent enantiomeric excess (ee) values (up to >99%). By using FsDAAO in combination with ammonia-borane in one pot, deracemization of these racemic carboxyl-substituted tetrahydroisoquinolines was achieved with conversions up to >98% and >99% ee. Preparative-scale deracemization of racemic 1,2,3,4-tetrahydroisoquinoline-1-carboxylic acid and 1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid was also demonstrated with good isolated yields (82% and 73%, respectively) and ee>99%. Our study provides an effective method for the synthesis of enantiomeric pure 1,2,3,4-tetrahydroisoquinoline carboxylic acids. This method is expected to provide access to chiral carboxyl-substituted 1,2,3,4-tetrahydroquinolines and 1,2,3,4-tetrahydro-ss-carbolines. (Figure presented.).
