PBTZ-169, also known as macozinone, is a new drug candidate that inhibits decaprenyl-phosphoribose-epimerase (DprE1), an essential enzyme involved in the cell wall biosynthesis of Corynebacterineae. The MIC values of PBTZ-169 ranged from 0.03 μg/mL to 0.0037 μg/mL. The MIC50 and MIC90 values of PBTZ-169 were 0.0075 and 0.030 μg/mL, respectively. The MIC for PBTZ-169 for N. brasiliensis HUJEG-1 was 0.0037 μg/mL. The MICs of SXT, DA-7218, and BTZ043 for this strain were 9.5/0.5, 8, and 0.125 μg/mL, respectively.

How to use

In Vitro:

PBTZ-169, inhibit decaprenylphosphoryl-β-d-ribose 2′-oxidase (DprE1) and display nanomolar bactericidal activity against Mycobacterium tuberculosis in vitro.

In Vivo:

PBTZ-169 can be suspend in 0.25% hydroxy-propylmethyl-cellulose. The administertration for PBTZ-169 is 100 mg/kg by gavage. The MIC50 and MIC90 values were 0.0075 and 0.030 μg/mL, respectively. The MIC for PBTZ-169 for N. brasiliensis HUJEG-1 was 0.0037 μg/mL. PBTZ-169 has improved potency, safety and efficacy in zebrafish and mouse models of tuberculosis (TB).
