Target	Posizolid shows very good anti-mycobacterial activity[1].
In Vitro	Posizolid is determined the activity of against 250 highly resistant pneumococci and 267 drug-susceptible isolates. Posizolid MICs for 50 and 90% of the strains tested are 1 and 2 μg/ml and 0.5 and 1 μg/ml, respectively, for the two isolate groups[2].
In Vivo	AZD5847 DSP (AZD2563 is prodrug) could not be detected in plasma 5 min after oral administration, suggesting rapid conversion of the prodrug to the parent molecule. In PK analysis, AZD5847(5 mg/kg) shows a low clearance (4.7 ml/min/kg) and volume of distribution (0.5 liter/kg) in mice, the half-life is 1.3 h[3]. Animal Model: Male BALB/c mice, aged 6 to 8 weeks, 30 to 40 g[3]. Dosage: 3, 10, 30, 100, 300, 600, and 900 mg/kg Administration: oral; collect blood samples at 5 min, 10 min, 15 min, 30 min, 1 h, 2 h, 4 h, 6 h, and 24 h Result: AZD5847 DSP can’t be detected in plasma 5 min. Animal Model: Male BALB/c mice, aged 6 to 8 weeks, 30 to 40 g[3]. Dosage: 250 mg/kg Administration: oral; collect blood and BAL fluid samples at 5 min, 15 min, 30 min, 1 h, 2 h, 4 h, 8 h, 16 h, 24 h, and 48 h Result: AZD5847(5 mg/kg) shows a low clearance (4.7 ml/min/kg) and volume of distribution (0.5 liter/kg) in mice, the half-life is 1.3 h.
