MAC13243（Cat No.:I000331）is a potent and selective inhibitor of the transcription factor NF-kB, specifically targeting the p65 subunit. It works by disrupting the NF-kB signaling pathway, which plays a central role in inflammation, immune response, and cancer progression. MAC13243 has shown promise in preclinical studies for modulating immune responses and reducing inflammation, making it a potential therapeutic candidate for autoimmune diseases, chronic inflammatory conditions, and certain cancers. Its ability to specifically inhibit NF-kB signaling without affecting other pathways gives it a distinct advantage in targeted therapy development.

Degradation of MAC13243 and studies of the interaction of resulting thiourea compounds with the lipoprotein targeting chaperone LolA.Barker CA,Allison SE,Zlitni S,Nguyen ND,Das R,Melacini G,Capretta AA,Brown ED, PMID: 23473681 DOI: 10.1016/j.bmcl.2013.02.005 Abstract: The discovery of novel small molecules that function as antibacterial agents or cellular probes of biology is hindered by our limited understanding of bacterial physiology and our ability to assign mechanism of action. We previously employed a chemical genomic strategy to identify a novel small molecule, MAC13243, as a likely inhibitor of the bacterial lipoprotein targeting chaperone, LolA. Here, we report on the degradation of MAC13243 into the active species, S-(4-chlorobenzyl)isothiourea. Analogs of this compound (e.g., A22) have previously been characterized as inhibitors of the bacterial actin-like protein, MreB. Herein, we demonstrate that the antibacterial activity of MAC13243 and the thiourea compounds are similar; these activities are suppressed or sensitized in response to increases or decreases of LolA copy number, respectively. We provide STD NMR data which confirms a physical interaction between LolA and the thiourea degradation product of MAC13243, with a Kd of ~150 μM. Taken together, we conclude that the thiourea series of compounds share a similar cellular mechanism that includes interaction with LolA in addition to the well-characterized target MreB.Copyright © 2013 Elsevier Ltd.
