Antibiotically active compounds derived from rifamycin S or from the corresponding hydroquinone, rifamycin SV, or from derivatives at least partially hydrogenated in positions 16, 17; 18, 19; 28, 29, such as the 16, 17; 18, 19 - tetrahydro- or the 16, 17; 18, 19; 28, 29 - hexahydro derivatives, which contain in position 3 a free or an aliphatically substituted amino group. The hydrocarbon radicals of the aliphatically substituted amino group can also be interrupted in their carbon chain by heteroatoms and/or be substituted by functional groups.
