The photochemical properties of two basic easily synthesized isatin N(2)-phenylhydrazones were investigated. Contrary to the corresponding isatin N(2)-diphenylhydrazones, only Z-isomers were isolated from the reaction mixtures during the synthesis due to their stabilization by intramolecular hydrogen bonding. Although the presence of the C=N double bond creates conditions for the formation of a...
The RNA-dependent DNA polymerase of Rous sarcoma virus is inhibited by N-methyl isatin beta-thiosemicarbazone and by thiosemicarbazide, but not by semicarbazide. These inhibitors also inactivate, upon contact with the virion, the transforming ability of Rous sarcoma virus. Sulfhydryl donors, such as 2-mercapto-ethanol, can prevent these effects. The RNA-directed activity of the purified polymer...
Plant used different mechanisms to avoidance drought stress. This study was conducted to evaluate the role of exogenous application of glycine betaine in improving drought tolerance of Brassica napus. The study was performed on randomized complete block design with 3 replications. Different amounts of glycine betaine i.e. 0, 100 and 200 mM in combination with various irrigation periods i.e. 3, ...
Multiple forms of reductases for several drug ketones were isolated from rabbit liver, but their interrelationship and physiologic roles remain unknown. We isolated cDNAs for four aldo-keto reductases (AKR1C30, AKR1C31, AKR1C32, and AKR1C33), which share high amino acid sequence identity with the partial sequences of two rabbit naloxone reductases. The four recombinant enzymes reduced a variety...
Isatin, N-methyl isatin and N-benzylisatin were smoothly monobrominated in the 5-position by treatment with pyridinium bromochromate (PBC) in acetic acid medium. In the similar conditions indigo underwent bromination and oxidation to give 5-bromoisatin in high yield.
Glycine is known as an inhibitory neurotransmitter in the spinal cord and forebrain but its precise role in the forebrain is largely overlooked. This investigation evaluated whether glycine alters acetylcholine, glutamate or dopamine release from striatal tissue using an in vitro approach. We observed that while glycine induced a robust (3)H-acetylcholine release ((3)H-ACh) from superfused stri...
Background and purpose: In recent years, the incidence of cancers has increased in the world. Therefore, many researches have focused on new strategies for treatment of cancers. Previous studies showed that quinolone antibacterials can inhibit human topoisomerases at high concentrations and can be considered as potential cytotoxic agents. On the other hand, 5,7-dibromoisatin is a cytotoxic agen...
Introduction: Inflammation as the body's defense response is accompanied with various diseases. Prostaglandins are major mediators of inflammation produced by the cyclooxygenase enzymes. So inhibitors of these enzymes can be effective in treating inflammation. There are reports of inhibition of these enzymes by isatin derivatives to control inflammation. Isatin is a heterocyclic compound whose...
The synthesis and evaluation of the anticancer activity of 3'-aryl-5'-arylidene-spiro[3H-indole-3,2'-thiazolidine]-2,4'(1H)-diones and spiro[3H-indole-3,2'-thi-azolidine]-2,4'(1H)-dione-3'-alkanoic acid esters were described. The structure of the compounds was determined by (1)H and (13)C NMR and their in vitro anticancer activity was tested in the National Cancer Institute. Among the tested co...
