MB67_CAR1/2 Inhibitors

The chemical class of MB67_CAR1/2 inhibitors comprises a diverse range of compounds known to modulate the activity of NR1I3, a nuclear receptor involved in various biological processes. This class includes both synthetic drugs and natural compounds, each demonstrating the ability to inhibit NR1I3 through different mechanisms, thereby impacting NR1I3-mediated gene expression. The inhibitors in this category are characterized by their interaction with NR1I3, either by competing with endogenous ligands or by interfering with the receptor's activation and downstream signaling. Ketoconazole exemplifies a direct interaction approach. It competitively binds to NR1I3, disrupting its activation by natural ligands, leading to the inhibition of gene expression mediated by this receptor. Similarly, Rifampicin, primarily an antibiotic, exhibits dual activity depending on its concentration. At higher concentrations, it inhibits NR1I3 by competing with its endogenous ligands. This competitive inhibition is a common theme among several MB67_CAR1/2 inhibitors. For instance, Indomethacin, a nonsteroidal anti-inflammatory drug, disrupts NR1I3-mediated gene expression by interfering with the receptor's activation.

Natural compounds form a significant portion of this class, each demonstrating unique interactions with NR1I3. Sulforaphane inhibits the activation of NR1I3, consequently reducing its gene regulatory activity. Curcumin, a well-known bioactive compound from turmeric, modulates NR1I3 activity by interfering with its activation and subsequent signaling. Resveratrol and Quercetin, both naturally occurring polyphenolic compounds, have been shown to inhibit NR1I3 activation, impacting the receptor's role in gene regulation. Additionally, a variety of flavonoids, including apigenin, luteolin, and kaempferol, have been identified as NR1I3 inhibitors. These flavonoids share a common trait of interfering with NR1I3 activation and its downstream signaling pathways, showcasing the wide range of natural compounds capable of modulating receptor activity. Ellagic acid, another polyphenolic compound, and Genistein, an isoflavone found in soy products, further extend the diversity of this class. Both compounds have been investigated for their ability to inhibit NR1I3 activation and influence the expression of genes regulated by this receptor. Naringenin, a flavanone in citrus fruits, also falls within this category, modulating NR1I3 activity and impacting its gene regulatory functions.
