Beige toYellow Powder | [Uses]
2-Thiocytosine has been used to investigate the reactions involved in hole transfer (HT) in X-irradiated doped cytosine monohydrate. | [Uses]
This compound has been shown to inhibit iodothyronine 5’-deiodinase, the enzyme responsible for the 5’-deiodination of thyroxine in human liver cells. | [General Description]
2-Thiocytosine is a potential antileukemic and anticancer agent. 2-Thiocytosine in solid state has been investigated by (1)H-(14)N NMR-NQR double resonance (NQDR) spectroscopy and theoretically by the quantum theory of atoms in molecules (QTAIM)/density functional theory (DFT). | [Purification Methods]
It is recrystallised from hot H2O and dried at 100o to constant weight. [Brown J Appl Chem (London) 9 203 1959, Russell et al. J Am Chem Soc 71 2279 1949.] It is used in transcription and translation studies [Rachwitz & Scheit Eur J Biochem 72 191 1977]. |
