??

This compound has been shown to inhibit iodothyronine 5’-deiodinase, the enzyme responsible for the 5’-deiodination of thyroxine in human liver cells.

?? ??

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].
