An efficient methodology was developed to generate novel N,N?-dialkyl-2-thiobarbituric acid based sulfonamides S1–S4 in good excellent yields (84%–95%). The synthesized compounds were docked screen their silico activities against two enzymes i.e., SARS-CoV-2 main protease enzyme with unliganded active site (2019-nCoV, coronavirus disease 2019, COVID-19) PDB ID: 6Y84 and M pro 6LU7. Furthermore,...

The reaction between barbituric acid or 2-thiobarbituric acid and different benzaldehydes, dependent upon the applied reaction conditions, selectively yields three different product types, i.e. 5-benzylidene(thio)barbituric acids II, symetric Michael adducts III or 5-phenyl-1H-pyrano[2,3-d]pyrimidine-2,4(3H,5H)-diones and 5-phenyl-2-thioxo-2,3-dihydro-1H-pyrano[2,3-d]pyrimidin-4(5H)-ones IV. Th...

Green tea polyphenols have demonstrated significant antioxidant, anticarcinogenic, anti-mutagenic and antidiabetic in numerous human, animal and in vitro studies. Hence present study was design to evaluate the influence of green tea in streptozotocin induced oxidative stress in mice. Morris water maze, Elevated plus maze and passive avoidance apparatus was used for the evaluation of learning an...

BACKGROUND Sodium metabisulfite is added to a commercial propofol emulsion as an antimicrobial agent. The sulfite ion (SO3(-2)) is capable of undergoing a number of reactions, including autooxidation and the promotion of lipid peroxidation. This study evaluated sulfite reactivity in propofol emulsions by determining thiobarbituric acid reacting substances (TBARS), sulfite depletion, and emulsio...

Lipid peroxides in tissues were fluorometrically determined using 1,3-diphenyl-2-thiobarbituric acid (DPTBA) as a fluorogenic reagent, and the results were compared with those obtained by the DPTBA-visible method, thiobarbituric acid (TBA)-fluorescence method, or TBA-visible method. The optimum conditions for determining lipid peroxides were analyzed by using brain homogenate. The optimum pH fo...

The manganese peroxidase (MnP) of Phanerochaete chrysosporium supported Mn(II)-dependent, H(2)O(2)-independent lipid peroxidation, as shown by two findings: linolenic acid was peroxidized to give products that reacted with thiobarbituric acid, and linoleic acid was peroxidized to give hexanal. MnP also supported the slow oxidation of phenanthrene to 2,2'-diphenic acid in a reaction that require...

Purpose: To compare the Lipid peroxidation and Total antioxidant status in women with gestational diabetes mellitus and normal pregnancy in our environment. Materials & Methods: This was a 2-year, cross sectional, case control study of 25 gestational diabetes mellitus (GDM) and 75 matched normal pregnant women at Ladoke Akintola University of Technology (LAUTECH) Teaching Hospital, Osogbo, Nige...
