Novobiocin

Biological Activity

[Description]:

Novobiocin (Albamycin) is a potent and orally active antibiotic. Novobiocin also is a DNA gyrase inhibitor and a heat shock protein 90 (Hsp90) antagonist. Novobiocin has the potential for the research of highly beta-lactam-resistant pneumococcal infections. Novobiocin shows anti-orthopoxvirus activity[1][2][3][4][6].

[Target]

HSP90


[In Vitro]

Novobiocin (1 mM) competitively inhibits ATP binding to gyrase B to interfere with nucleotide binding and interferes with the association of the co-chaperones Hsc70 and p23 with Hsp90[1]. Novobiocin (200 µM; 24 h) inhibits the rate of repair of both cis-DDP and BCNU induced DNA interstrand cross-links and with a corresponding decrease in the clonogenic survival of the human glioblastoma multiforme cells[2]. Novobiocin (0.3 mM; 48 hours) induces a caspase-3/7 enzyme–dependent apoptosis assays with an induction of approximately three- to fivefold of apoptotic cells in K562, HL60, Mutz-2[5].

[In Vivo]

Novobiocin (25, 50, 100, 200 mg/kg; s.c.; 4 times at 1, 5, 24 and 48 h after infection) shows anti-infection activity in mice infected with amoxicillin-resistant Streptococcus pneumoniae[3]. Animal Model: 30 g adult female Swiss mice (sepsis induced by the penicillin-susceptible strain (AR33118))[3] Dosage: 25, 50, 100, 200 mg/kg Administration: S.c.; given at 1, 5, 24 and 48 h after infection Result: Showed anti-infection activity in mice infected with amoxicillin-resistant S. pneumoniae.
