Biological Activity

In vitro: Delpazolid (LCB01-0371), at concentrations of 1×MIC and 2×MIC, has bacteriostatic activity against MSSA and MRSA after 24 h. At concentrations of 4×MIC and 8×MIC, Delpazolid shows bacteriostatic activity, but there is no regrowth at concentrations of 4×MIC and 8×MIC after 24 h of incubation. The survival of M. abscessus is greatly decreased in the presence of Delpazolid (LCB-0371) (MIC50=1.2 μg/mL). Delpazolid dramatically decreases the number of intracellular mycobacteria present at 2 days after infection at concentrations of 0.1, 1, and 10 μg/mL.

In vivo: When administered orally, Delpazolid (LCB01-0371) shows potent protective effects against systemic infections caused by Gram-positive and Gram-negative bacteria. Against infection caused by S. aureus Giorgio (MSSA), the ED50 of Delpazolid is 4.53 mg/kg of body weight. Against S. aureus p125 (MRSA), the ED50 of Delpazolid is 2.96 mg/kg. When Delpazolid (LCB-0371) is administered at 100 mg/kg daily (by gavage), the colony-forming unit (CFU) counts tend to be decreased in the lungs of mice at 7 days after infection.

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
