turmeric (cucurma longa) has been used as an antioxidant agent in medical as well as health sciences some years ago. however, it has not been applied in tissue culture till now. browning tissues is result of tissue damages caused by polyphenoloxidase enzyme. in order to study this problem and reduce browning, explants are cultured in culture media containing antioxidants including citric acid, ...
In the title compound, C(11)H(16)ClNO, the side chain of the ethyl-amine group is almost perpendicular to the benzene ring; the dihedral angle between the C/C/N plane of the ethyl-amine grouping and the benzene plane is 87.4 (2)°. An intramolecular N-H⋯O hydrogen bond occurs. In the crystal structure, mol-ecules are connected weakly by O-H⋯N hydrogen bonds, forming a tetra-mer around the symmet...
we report herein the development of a highly sensitive colorimetric method for the detection of 4-hydroxy-2-mercapto-6-methylpyrimidine (mtu) which acts as an anti-thyroid drug utilizing citrate capped gold nanoparticles (au-nps). this thiol-containing molecule exhibits intriguing affinity with au-nps. the reactivity involves the displacement of the citrate shell by the thiolate shell followed ...
Dimroth rearrangement in a thiadiazole—triazole system was first observed by Kindt—Larsen and Pedersen [1] when 5-mercapto-l-phenyl-l,2,3-triazole was formed from 5-anilino-l,2,3-thiadiazole. A similar rearrangement has been ob served to take place with 4-substituted 5-amino-l,2,3-thiadiazoles [2] and 4-acyl-5-arylamino-l,2,3-thiadiazoles [3]. In the present work the kinetics of the rearrangem...
Thyroid hormones influence brain development through regulation of gene expression mediated by nuclear receptors. Nuclear receptor concentration increases rapidly in the human fetus during the second trimester, a period of high sensitivity of the brain to thyroid hormones. In the rat, the equivalent period is the last quarter of pregnancy. However, little is known about thyroid hormone action i...
