1. Theoretical study of the internal elimination of xanthates using ONIOM additivity and pseudopotentials / Estudo teorico do mecanismo de eliminação interna de xantatos usando o metodo aditivo de energia atraves de ONIOM com pseudopotencial
The gas-phase internal elimination (Ei) reaction of xanthates and the decomposition of xanthic acid have been investigated using ONIOM Additivity Expression and Pseudopotential, ONIOM[CCSD(T)/CEP-311 (2d,f):MP2/CEP-31G//MP2/CEP-31G]. The higest leveI representation was calculated by means of CCSD(T)/CEP-31G and electronics and sterics effects by MP2/CEP-31G.

2. DNA and RNA virus species are inhibited by xanthates, a class of antiviral compounds with unique properties.
Various DNA and RNA virus species are inhibited by xanthate compounds at concentrations that leave the mitotic activity of uninfected cells unimpaired. The concentration of tricyclodecan -9-yl- xanthogenate that reduces the yield of herpes simplex virus types 1 and 2 by 50% is between 4.5 and 33 microM. The replication of DNA viruses such as simian virus 40
