Introduction of 16846-24-5 :

Josamycin (EN-141) is an orally active macrolide antibiotic exhibiting antimicrobial activity against a wide spectrum of pathogens, such as bacteria. The dissociation constant Kd from ribosome for Josamycin is 5.5 nM[1][2]. IC50 & Target:Kd: 5.5 nM (ribosome)[1] In Vivo:Blood and tissue levels of Josamycin after oral administration are 200 mg/kg to rabbits. Tissue levels are generally much higher than the blood levels, and 3 h after the administration, when the blood level is very low, the tissue levels are rather higher than those 1 h after the dose. One hour after the medication, the level in the lungs is the highest of all the tissue levels[2].
