New spiro-piperidylrifamycin derivatives are presented. These compounds were synthesized from the reaction of 3-amino-4-iminorifamycin S and enantiomerically pure 4-piperidones, which generate diasteroisomeric rifabutin analogues with a new stereocentre at the spiranic carbon. The (1)H and (13)C NMR spectra of these

Mycothiol is comprised of N-acetylcysteine (AcCys) amide linked to 1D-myo-inosityl 2-amino-2-deoxy-alpha-D-glucopyranoside (GlcN-Ins) and is the predominant thiol found in most actinomycetes. Mycothiol S-conjugate amidase (Mca) cleaves the amide bond of mycothiol S-conjugates of a variety of alkylating agents and xenobiotics
