Chemicals that are classified as SIMC1 inhibitors are diverse and influence various aspects of the SUMOylation pathway and related cellular processes. SUMOylation involves the attachment of Small Ubiquitin-like Modifier (SUMO) proteins to lysine residues on target proteins, a process that is essential for a variety of cellular functions, including nuclear-cytosolic transport, transcriptional regulation, apoptosis, protein stability, and response to stress.

The proposed inhibitors work by modulating different steps in the SUMOylation cascade, which may affect the function of SIMC1. Anacardic Acid and Ginkgolic Acid, for example, target the initial steps in the SUMOylation process by inhibiting enzymes responsible for activating SUMO proteins. ML-792 and Spectomycin B1 also disrupt the SUMOylation pathway by targeting the E1 and E2 enzymes, respectively. Tenovin-6 alters the balance of SUMOylation through inhibition of SIRT1, which is indirectly involved in the deSUMOylation process. Other compounds, like Chloroquine and Pyr-41, may influence the degradation or recycling of SUMOylated proteins and thus indirectly affect SIMC1 function. Proteasome inhibitors such as Bortezomib can increase the levels of SUMOylated proteins, which may have downstream effects on SIMC1 activity. Sulfasalazine, through its NF-kB inhibitory activity, can modulate the expression of genes related to the SUMOylation pathway.
