DprE1-IN-4 是一种有效的非共价DprE1抑制剂，其IC50为0.90 μg/mL。DprE1-IN-4 有较强的体外活性，抑制结核 H37Rv 和耐药结核菌株的 MIC 值分别为 0.12 μg/mL 和 0.24 μg/mL。DprE1-IN-4 表现出可接受的药代动力学特性，并且在急性肺结核小鼠模型中表现出显著的杀菌活性。

DprE1-IN-4 is a potent and orally active noncovalent DprE1 inhibitor with an IC 50 of 0.90 μg/mL. DprE1-IN-4 exhibits potent in vitro activity against M. tuberculosis H37Rv and drug-resistant tuberculosis strain with MIC values of 0.12 μg/mL and 0.24 μg/mL, respectively. DprE1-IN-4 displays acceptable pharmacokinetic property and shows significant bactericidal activity in an acute mouse model of tuberculosis [1].

DprE1-IN-4 displays potent activity against M. tuberculosis, it is against isolated clinical strains H37Rv, 13946a, 14862b and PBTZ169-resistant strain with MIC values of 0.12 μg/mL, 0.24 μg/mL, 0.24 μg/mL and 0.48 μg/mL, respectively [1].DprE1-IN-4 (0.76-16 μg/mL) shows a decrease in potency against only DprE1-overexpressing strains but not against DprE2-overexpressing and wild-type strains. The IC 50 value is 0.9±0.2 μg/mL for DprE1 [1].

DprE1-IN-4 exhibits acceptable pharmacokinetic property after p.o. and i.v., DprE1-IN-4 (oral administration, 50 mg/kg) exhibits high plasma exposure ((AUC) 0-∞ =657 ng·h/mL) and high maximum plasma concentration (C max =486 ng/mL). It exhibits oral bioavailability (F=7.9%) and is deemed worthy of further evaluation in in vivo efficacy studies [1].DprE1-IN-4 (oral gavage; 100 mg/kg; once daily; 3 weeks) showed potent in vivo activity, reducing the bacterial burden in the lungs by 2.02 log 10 CFU compared with the untreated control group [1].
