Aminosalicylic Acid
4-Aminosalicylic acid (PAS), an anti-tuberculosis drug discovered in Sweden by chemist Jörgen Lehmann, who first tried it late in 1944: it was the second effective drug against tuberculosis after streptomycin and is now used for resistant forms. This family brings together other impurities.
Did you know?It had already been synthesised in 1902: Lehmann rediscovered it after reading that the tuberculosis bacillus avidly metabolised salicylic acid, and thought of a similar molecule to block it.
