HC103A
HC103A is an Antibacterial agent and a DosS/DosT histidine sensor kinase inhibitor, with an IC50 of 0.5 μM against DosS and ~5 μM against DosT of *Mycobacterium tuberculosis*. HC103A inhibits the autophosphorylation of DosS/DosT. HC103A suppresses hypoxia-induced triacylglycerol synthesis and the viability of Mtb. HC103A can be used in the research of tuberculosis.

Biological Activity
HC103A (0.1-100 μM; 6 d) potently and selectively inhibits DosR-dependent GFP fluorescence in Mycobacterium tuberculosis CDC1551(hspX′::GFP) with an EC50 of 2.7 μM without affecting bacterial growth[1].
HC103A (40 μM) reduces triacylglycerol accumulation by 56% in Mycobacterium tuberculosis CDC1551, disrupting a key persistence-associated lipid metabolism pathway[1].
HC103A (0-60 μM; 1 h) directly inhibits autophosphorylation of purified Mycobacterium tuberculosis DosS (IC50 0.5 μM) and DosT (IC50 ~5 μM) sensor kinases without altering their heme redox status[1].
