OPC-167832 is a potent and orally active dprE1 Inhibitor with an IC50 of 0.258 μM. OPC-167832 has antituberculosis activity and can be used for the research of tuberculosis caused by Mycobacterium tuberculosis[1]. OPC-167832 exhibits very low MICs against laboratory strains of M. tuberculosis H37Rv (MIC: 0.0005 μg/ml) and Kurono (MIC: 0.0005 μg/ml) and strains with monoresistance to rifampin (RIF), isoniazid (INH), ethambutol (EMB), streptomycin (STR), and pyrazinamide (PZA) (MIC: 0.00024-0.001 μg/ml). However, OPC-167832 has minimal or no activity against standard strains of nonmycobacterial aerobic and anaerobic bacteria[1].The IC90 values of OPC-167832 against intracellular M. tuberculosis strains H37Rv and Kurono are 0.0048 and 0.0027 μg/ml, respectively. OPC-167832 shows bactericidal activity against intracellular M. tuberculosis at a low concentration, and the bactericidal activity is saturated at concentrations of 0.004 μg/ml or higher[1]. OPC-167832 (oral administration; 0.625-10 mg/kg) exhibits a good pharmacokinetic characteristic. The plasma reaches peak at 0.5 h to 1.0 h (tmax) and is eliminated with a half-life (t1/2) of 1.3 h to 2.1 h OPC-167832 distribution in the lungs is approximately 2 times higher than that in plasma, and the Cmax and AUCt of OPC-167832 in plasma and the lungs shows dose dependency[1].OPC-167832 (oral administration; 0.625-10 mg/kg; 4 weeks) significantly reduces lung CFU compared to the vehicle group. The dose-dependent decrease of lung CFU is observed from 0.625 mg/kg to 2.5 mg/kg. In a M. tuberculosis Kurono-infected ICR female mice model. OPC-167832 combines with DMD, BDQ, or LVX via oral gavage exhibits significantly higher efficacies than each single agent alone[1].[1].OPC-167832 (oral gavage; 2.5 mg/kg; combination with DCMB; 12 weeks) demonstrates the most potent efficacy when compares with DC, DCB. The lung CFU count after 6 weeks of treatment is below the detection limit, and at the end of just 8 weeks of treatment, the bacteria in the lungs of all the evaluated mice had already been eradicate[1].

One of two assembly initiator proteins for the 30S subunit, it binds directly to 16S rRNA where it nucleates assembly of the body of the 30S subunit.; With S5 and S12 plays an important role in translational accuracy; many suppressors of streptomycin-dependent mutants of protein S12 are found in this protein, some but not all of which decrease translational accuracy (ram, ribosomal ambiguity mutations).; Plays a role in mRNA unwinding by the ribosome, possibly by forming part of a processivity clamp.; Protein S4 is also a translational repressor protein, it controls the translation of the alpha-operon (which codes for S13, S11, S4, RNA polymerase alpha subunit, and L17) by binding to its mRNA.; Also functions as a rho-dependent antiterminator of rRNA transcription, increasing the synthesis of rRNA under conditions of excess protein, allowing a more rapid return to homeostasis. Binds directly to RNA polymerase.; Part of the processive rRNA transcription and antitermination complex (rrnTAC). The complex forms an RNA-chaperone ring around the RNA exit tunnel of RNA polymerase (RNAP). It supports rapid transcription and antitermination of rRNA operons, cotranscriptional rRNA folding, and annealing of distal rRNA regions to allow correct ribosome biogenesis. This subunit may play a particular role in long-distance rRNA annealing needed for pre-rRNA processing.
