– Zifanocycline (KBP-7072) TFA is a semi-synthetic aminomethylcycline antibiotic with oral bioavailability that targets bacterial ribosomes to impede their function. Displaying a broad spectrum of in vitro antimicrobial efficacy, it combats both Gram-positive and Gram-negative bacteria, including numerous multidrug-resistant strains. Clinical investigations focus on treating acute bacterial skin and skin structure infections, community-acquired bacterial pneumonia, and complicated intra-abdominal infections [1] [2].
