Biological Activity
Sarecycline hydrochloride is a narrow-spectrum tetracycline-class antibiotic. Sarecycline hydrochloride possesses anti-inflammatory properties and potent activity against Gram-positive bacteria, including activity against multiple strains of Cutibacterium acnes. Sarecycline hydrochloride interferes with tRNA accommodation and tethers mRNA to the 70S ribosome[1][2][3].
In Vitro
Sarecycline inhibits 55 clinical isolates of C. acnes, and the MIC values for Sarecycline ranged from 0.5 to 16 µg/ml; the MIC50 was 0.5 µg/ml, and the MIC90 was 4 µg/ml. Sarecycline, exhibits activity against the macrolide-resistant organisms[1]. Sarecycline hydrochloride exhibits minimal activity against enteric aerobic Gram-negative bacteria[2].
In Vivo
Sarecycline hydrochloride (0.33-9 mg/kg; i.v.) show potent activity against S. aureus in a murine neutropenic thigh infection model[1]. Animal Model: Female SD-1 mice (A murine neutropenic thigh wound infection model)[1] Dosage: 0.33, 1, 3, or 9 mg/kg Administration: Intravenously Result: Achieved a 2-log10 reduction in the bacterial burden in the thigh at a dose comparable to that of doxycycline, with ED50s of 8.23 and 8.32 mg/kg, respectively.
