The effectiveness in TB treatment is difficult because the structural composition of the mycobacterial cell wall is very complicated, which makes many drugs ineffective. Tuberculosis is still one of the most imperative infectious disease worldwide becouse its important reason is drug resistant, persistent or latent tuberculosis and synergism with HIV. Furthermore no any new chemical entity has come. The recently application of modern drug design promise to bring significant development in the fight against TB. In present review we discussed brief introduction of tuberculosis.

Membered Heterocycle

Pentacarbonyl(thietane)tungsten complexes react with thiocyanate, [SCN]-, and SiO2/H2O by insertion of the CN group into a S—C bond of the four-membered heterocycle, 1,3-migration of the pentacarbonyltungsten fragment and protonation of the nitrogen atom to give tungsten-coordinated thiazinthione complexes. Analogously, the reactions of a thietane tungsten complex with [SeCN]- and SiO2/H2O affords a thiazinselone complex. A selenazinthione complex is obtained from a selenetane complex and [SCN]- (+ SiO2/H2O). The insertions are regiospecific and stereoselective. The structure of the trans-isomer of a pentacarbonyl-(thiazinthione) complex has been established by X-ray structure analysis.
