In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Discovery of Novel Thiophene-arylamide Derivatives as DprE1 Inhibitors with Potent Antimycobacterial Activities, published in 2021-05-13, which mentions a compound: 4045-24-3, mainly applied to thiophene arylamide derivative design synthesis DprE1 inhibitor; antimycobacterial activity DprE1 inhibitor thiophene arylamide derivative SAR; mol docking pharmacokinetic property selected thiophene arylamide, Synthetic Route of C6H13NO.

In this study, we report the design and synthesis of a series of novel thiophene-arylamide compounds derived from the noncovalent decaprenylphosphoryl-β-D-ribose 2′-epimerase (DprE1) inhibitor TCA1 through a structure-based scaffold hopping strategy. Systematic optimization of the two side chains flanking the thiophene core led to new lead compounds bearing a thiophene-arylamide scaffold with potent antimycobacterial activity and low cytotoxicity. Compounds I, II, III [X = H,F] exhibited potent in vitro activity against both drug-susceptible (min. inhibitory concentration (MIC) = 0.02-0.12μg/mL) and drug-resistant (MIC = 0.031-0.24μg/mL) tuberculosis strains while retaining potent DprE1 inhibition (half maximal inhibitory concentration (IC50) = 0.2-0.9μg/mL) and good intracellular antimycobacterial activity. In addition, these compounds showed good hepatocyte stability and low inhibition of the human ether-á-go-go related gene (hERG) channel. The representative compound III [X = H] with acceptable pharmacokinetic property demonstrated significant bactericidal activity in an acute mouse model of tuberculosis. Moreover, the mol. docking study of template compound I provides new insight into the discovery of novel antitubercular agents targeting DprE1.

DS-S-51, the main research direction is Rhizobium chlorohydroxybutyrate sequence stereoselective reduction.Application of 58081-05-3.

(S)-4-Chloro-3-hydroxybutyrate (CHB) is essential for the synthesis of biol. and pharmacol. important compounds Rhizobium sp. DS-S-51 isolated from soil samples showed hydrolytic activity toward (R)-CHB in the racemate to (R)-3-hydroxy-γ-butyrolactone (HL) under a simple composition of the reaction. Residual (S)-CHB was obtained with high optical purity. The gene encoding the enzyme concerned, designated CHB hydrolase, was isolated from DS-S-51, and the gene was highly expressed in Escherichia coli JM109. When the resolution of racemic Me CHB (CHBM) as a substrate was performed using this recombinant cell, JM109 (pKK-R1), the hydrolytic activity was found to be 40-fold greater than that of DS-S-51, and the maximum concentration of the substrate added increased 2-fold. Moreover, (R)-HL was also obtained without decreasing the optical purity compared with that when (R)-CHBM was used as a substrate.
