The stereochemistry at carbon 3 of pyruvate lyase condensation products. Aldolases forming condensation products racemic at carbon 4.
Both the Schiff base-mediated 2-keto-4-hydroxyglutarate aldolase of liver and the metal-activated a-keto-/3-deoxyhexarate aldolase of Escherichia coli condense pyruvate and glyoxylate to form (4-RS)-Z-keto-4-hydroxyglutarate. Both enzymes catalyzed a condensation between [3-3H3]pyruvate and glyoxylate. It was found that C-C synthesis occurred 6 to 7 times faster than C-T bond cleavage. Thus, py...

متن کاملInhibition of the Corrosion of Mild Steel in Hydrochloric Acid by Isatin and Isatin Glycine
The inhibition of corrosion of mild steel in hydrochloric acid by isatin glycine (ING) and isatin (IN) at 30-60 o C and concentrations of 0.0001 M to 0.0005 M was studied via weight loss method. At the highest inhibitor concentration studied ING exhibited inhibition efficiency of 87% while IN exhibited 84% at 60 o C. A chemical adsorption mechanism was proposed on the basis of the temperature e...
متن کامل5-(Trifluoromethoxy)isatin
THE TITLE COMPOUND [SYSTEMATIC NAME: 5-(trifluoro-meth-oxy)-1H-indole-2,3-dione], C9H4F3NO3, crystallized with two mol-ecules in the asymmetric unit. Inter-molecular N-H⋯O hydrogen bonds link the mol-ecules to form layers parallel to the ab plane. In addition, π-π stacking inter-actions are observed with a centroid-centroid distance of 3.721 (1) Å. The near planarity of the two isatin ring syst...
متن کاملAnti-Tubercular Activity of Isatin Derivatives
Tuberculosis (TB) remains among the world’s great public health challenges. Worldwide resurgence of TB is due to two major problems: the acquired immunodeficiency syndrome (AIDS) epidemic, which started in the mid-1980s, and the outbreak of multidrug resistant tuberculosis (MDR-TB). Thus, there is an urgent need for anti-TB drugs with improved properties such as: Enhanced activity against MDR s...
