概述
Rifabutin 是一种半合成的Ansamycin 抗生素，具有有效的抗分枝杆菌特性。A semisynthetic antibacterial derivative of Rifamycin S.
Information
Rifabutin (LM427, Ansamycin) is a semisynthetic ansamycin antibiotic, used in the treatment of Mycobacterium avium intracellulare (MAI) and tuberculosis.
In vitro
Rifabutin has a broad spectrum of antimicrobial activity. Rifabutin is considerably more active than rifampin in vitro against the Mycobacterium avium complex (MAC), Mycobacterium tuberculosis, and Mycobacterium leprae. Rifabutin also is active against most atypical mycobacteria, including Mycobacterium kansasii, but Mycobacterium chelonae is relatively resistant. Rifabutin also is active against staphylococci, group A streptococci, Neisseria gonorrhoeae, Neisseria meningitidis, Haemophilus influenzae, Haemophilus ducreyi, Campylobacter jejuni, Helicobacter pylori, Chlamydia trachomatis, and Toxoplasma gondii. Rifabutin shows an isoenzyme-selectivity profile similar to that produced by Rifampicin, but the maximally achievable induction of cytochrome P-450 3A by Rifabutin is about two-fold lower compared with Rifampicin. Rifabutin enhances the glucuronidation of 1-naphthol, 4-hydroxybiphenyl and beta-estradiol by a factor of two to three.
In vivo
Rifabutin increases the human CYP3A4 mRNA expression, CYP3A4 protein content, testosterone 6ss-hydroxylase activity and dexamethasone 6-hydroxylase activity by 7.4-, 3.0-, 2.4- and 1.9-fold, respectively, in the chimeric mice. Rifabutin (100 mg/kg) combined with Pyrimethamine (10 mg/kg) protects 75% of the mice infected with a lethal inoculum of tachyzoites or cysts of Toxoplasma gondii against death.
