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).
Application
2-Thiocytosine has been used to investigate the reactions involved in hole transfer (HT) in X-irradiated doped cytosine monohydrate.
