Cytisine is a nicotine agonist, and as a pharmaceutical preparation it is available for the treatment of nicotinismCytisine derivative varenicline was approved in 2006 as asmoking cessation drug.

Plants containing cytisine, including the Common Broom and Mescalbean have also been used recreationally. Positive.

5'-Nucleotides are produced through the hydrolytic reaction from Ribonucleic acid(RNA) as raw material by enzymatic catalysis to form four kinds of nucleotides 5- 'AMP (adenosine-5'-monophosphate), 5'-GMP•2Na(guanosine-5'-monophosphate, disodium salt), 5'-CMP(cytidine-5'-monophosphate)-, 5'-UMP•2Na (uridine- 5'-monophosphate,Disodium salt) .By the chromatographic isolation, four kinds of separated 5'-nucleotide products with high purity can be obtained. These products can be widely applied in medicine, reagent, fine chemical industry, and additive of food fields etc.
