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. 121-66-4, Name is 5-Nitrothiazol-2-amine, molecular formula is C3H3N3O2S. In a Article，once mentioned of 121-66-4, Computed Properties of C3H3N3O2S
Twenty four novel 2-[3-(4-bromo-2-fluorobenzyl)-4-oxo-3,4-dihydro-1- phthalazinyl]acetic acid amides were synthesized from phthalic anhydride and were subjected to in vitro and in vivo evaluation against log- and starved phase of mycobacterial species and Mycobacterium tuberculosis isocitrate lyase enzyme inhibition studies. Among the compounds screened, 2-(2-(4-bromo-2-fluorobenzyl) -1,2-dihydro-1-oxophthalazin-4-yl)-N-(2,6-dimethylphenyl)acetamide (5j) inhibited all eight mycobacterial species with MIC’s ranging from 0.08 to 5.05 mum and was non-toxic to Vero cells till 126.43 mum. Four compounds were tested against starved culture of Mycobacterium tuberculosis and they inhibited with MIC’s ranging from 3.78 to 23.2 mum. Some compounds showed 40-66% inhibition against Mycobacterium tuberculosis isocitrate lyase enzyme at 10 mum. The docking studies also confirmed the binding potential of the compounds at the isocitrate lyase active site. In the in vivo animal model, 5j reduced the mycobacterial load in lung and spleen tissues with 1.38 and 2.9-log10 protections, respectively, at 25 mg/kg body weight dose.
