In 1957, a sample of soil coming from a pine wood on the French Riviera was brought for analysis to the Lepetit Pharmaceuticals research lab in Milan, Italy. There, a research group headed by Prof. Piero Sensi (1920-) discovered a new bacterium. This new species appeared immediately of great scientific interest since it was producing a new class of molecules with antibiotic activity. Rifampicin was introduced in 1967, as a major addition to the cocktail-drug treatment of tuberculosis and inactive meningitis, along with isoniazid, ethambutol, pyrazinamide and streptomycin. Because Prof. Sensi and some of his fellow researchers were particularly fond of the French crime story Rififi (about a jewel heist and rival gangs), they decided to call these compounds "Rifamycins". After two years of attempts in order to obtain more stable semi-synthetic products, in 1959 a new molecule with high efficacy and good tolerability was produced and was named "Rifampicin".

 Rifampicin(13292-46-1) is used to treat tuberculosis and infections, and should be used in combination with other antibiotics. In combination with fusidic acid, it is used in prophylactic therapy against Neisseria meningitidis (meningococcal) infection.

 Rifampicin , its cas register number is 13292-46-1. It also can be called Rifampin ; Rimactane ; Rifadin ; Rimactan ; and 3-[[(4-methyl-1-piperazinyl)imino]methyl]-rifamycin . It is a bactericidal antibiotic drug of the rifamycin group, and is a semisynthetic compound derived from Amycolatopsis rifamycinica. There are various types of rifamycins from which this is derived, but this particular form is by far the most clinically effective. It inhibits DNA-dependent RNA polymerase in bacterial cells by binding its beta-subunit, thus preventing transcription to RNA and subsequent translation to proteins.
