New discoveries in chemical research and development in 2021. Quality Control of 6,7-Dimethoxy-1,2,3,4-tetrahydroisoquinoline, A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 1745-07-9, Name is 6,7-Dimethoxy-1,2,3,4-tetrahydroisoquinoline, molecular formula is C11H15NO2. In a Article，once mentioned of 1745-07-9
Various 2-(sub)-3-fluoro/nitro-5,12-dihydro-5-oxobenzothiazolo[3,2-a]quinoline-6 -carboxylic acid derivatives were synthesized from 2-aminothiophenol by a five-step reaction, evaluated for in-vitro and in-vivo antimycobacterial activities against Mycobacterium tuberculosis H37Rv (MTB), multi-drug resistant Mycobacterium tuberculosis (MDR-TB), and Mycobacterium smegmatis (MC2), and also tested for the ability to inhibit the supercoiling activity of DNA gyrase from M. smegmatis. Among the thirty-four synthesized compounds, 2-(3-(diethylcarbamoyl)piperidin-1-yl)-)-3-fluoro-5,12-dihydro-5-oxobenz othiazolo[3,2-a]quinoline-6-carboxylic acid (7l) was found to be the most active compound in vitro with MIC of 0.18 and 0.08 muM against MTB and MTR-TB, respectively. Compound 7l was found to be 2 and 570 times more potent than isoniazid against MTB and MDR-TB, respectively. In the in-vivo animal model 7l decreased the bacterial load in lung and spleen tissues with 2.78 and 3.12 – log 10 protections, respectively, at the dose of 50 mg/kg body weight.
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 1745-07-9, help many people in the next few years.Quality Control of 6,7-Dimethoxy-1,2,3,4-tetrahydroisoquinoline
