MAC13243 is primarily used in research settings to study bacterial cell processes, particularly those involving the divisome complex. It is known to inhibit the function of the FtsZ protein, which plays a critical role in bacterial cell division. By targeting FtsZ, this compound helps researchers explore mechanisms of bacterial growth and division, making it a valuable tool in understanding antibiotic resistance and developing new antibacterial strategies. Its application is significant in microbiology and drug discovery, where it aids in identifying potential targets for novel antibiotics.
