HMGN3 Inhibitors
Chemical inhibitors of HMGN3 can exert their effects through various mechanisms, all leading to the functional inhibition of this protein's role in chromatin remodeling and transcriptional regulation. Trichostatin A, for instance, is a histone deacetylase inhibitor that can increase histone acetylation, which in turn can counteract the chromatin-condensing effects exerted by HMGN3, thus inhibiting its activity. Similarly, Mithramycin A, by binding to GC-rich sequences in DNA, can displace HMGN3 from its preferential nucleosome binding sites, thereby inhibiting its function. Chloroquine's ability to intercalate into DNA disrupts the binding of HMGN3 to nucleosomes, hindering its ability to affect chromatin structure and function. Echinomycin, by binding to DNA at CpG sequences, prevents HMGN3 from associating with its target DNA sequences on nucleosomes, impeding its function. Additionally, Pentamidine and Netropsin target AT-rich regions and minor grooves of DNA, respectively, and their binding can compete with HMGN3 for DNA binding sites, potentially inhibiting its chromatin-binding ability.
Furthermore, Distamycin, by attaching to AT-rich sequences in the minor groove of DNA, can prevent HMGN3 interactions with these sites, inhibiting its role in chromatin remodeling. Chromomycin A3 binds to GC-rich DNA sequences, which could occupy the DNA binding sites for HMGN3 and thus inhibit its modulatory function on chromatin. Mitoxantrone and Daunorubicin intercalate into DNA, potentially disrupting HMGN3's interaction with nucleosomes and inhibiting its role in chromatin structure modification. Actinomycin D, by binding to DNA at the transcription initiation complex, can inhibit interactions between DNA and HMGN3. Lastly, Novobiocin's inhibition of DNA gyrase and topoisomerase II can alter chromatin structure in a manner that diminishes the conducive binding of HMGN3, thus inhibiting its ability to modulate gene expression through chromatin remodeling.

Trichostatin A | 58880-19-6 | sc-3511 sc-3511A sc-3511B sc-3511C sc-3511D | 1 mg 5 mg 10 mg 25 mg 50 mg | $152.00 $479.00 $632.00 $1223.00 $2132.00 | 33 | |
Trichostatin A is a histone deacetylase inhibitor. HMGN3 modulates chromatin structure and function by binding to nucleosomes, altering histone acetylation and transcription factor access. By inhibiting histone deacetylase, Trichostatin A can increase histone acetylation, which may counteract the chromatin-condensing effects of HMGN3, thereby functionally inhibiting its activity in chromatin remodeling. | ||||||
Mithramycin A | 18378-89-7 | sc-200909 | 1 mg | $55.00 | 6 | |
Mithramycin A binds to GC-rich sequences in the minor groove of DNA. HMGN3 preferentially binds to nucleosomes near transcriptionally active regions often enriched with GC sequences. By binding to these sequences, Mithramycin A can displace HMGN3 from its preferential binding sites, thus inhibiting HMGN3’s role in facilitating transcriptionally active chromatin states. | ||||||
Chloroquine | 54-05-7 | sc-507304 | 250 mg | $69.00 | 2 | |
Chloroquine is known for its ability to intercalate into DNA, which can disrupt DNA-protein interactions. This intercalation can hinder the binding of HMGN3 to nucleosomes, thereby inhibiting its ability to affect chromatin structure and transcriptional regulation. | ||||||
Quinomycin A | 512-64-1 | sc-202306 | 1 mg | $166.00 | 4 | |
Quinomycin A is a bisintercalator that binds to DNA at CpG sequences. As HMGN3 has been shown to bind nucleosomes with an affinity for certain DNA sequences, echinomycin's binding could prevent HMGN3 from associating with its target DNA sequences on the nucleosomes, thus inhibiting its function. | ||||||
Pentamidine | 100-33-4 | sc-208158 sc-208158A | 25 mg 50 mg | $380.00 $568.00 | ||
Pentamidine is an agent that binds to AT-rich regions of the minor groove of DNA. By binding to these regions, Pentamidine could compete with HMGN3 for DNA binding sites, potentially inhibiting the ability of HMGN3 to bind to chromatin and exert its biological effects on chromatin structure and function. | ||||||
Chromomycin A3 | 7059-24-7 | sc-200907 | 10 mg | $260.00 | ||
Chromomycin A3 binds to GC-rich sequences of DNA and has been shown to inhibit protein-DNA interactions. This binding can inhibit the association of HMGN3 with chromatin by occupying the DNA binding sites that HMGN3 would typically interact with, thereby inhibiting its ability to modulate chromatin structure. | ||||||
Mitoxantrone | 65271-80-9 | sc-207888 | 100 mg | $285.00 | 8 | |
Mitoxantrone intercalates into DNA and can disrupt DNA-protein interactions. This intercalation could inhibit HMGN3’s interaction with nucleosomes, potentially inhibiting HMGN3's role in chromatin remodeling and transcriptional regulation. | ||||||

Actinomycin D binds to DNA at the transcription initiation complex and can inhibit interactions between DNA and DNA-binding proteins. This inhibition can extend to HMGN3, preventing its binding to chromatin and thus inhibiting its role in chromatin organization and transcriptional regulation. | ||||||

Novobiocin is an inhibitor of DNA gyrase and topoisomerase II, enzymes involved in DNA supercoiling and chromatin dynamics. By inhibiting these enzymes, Novobiocin could alter the chromatin structure in a way that is less conducive to HMGN3 binding, thus inhibiting the functional role of HMGN3 in chromatin remodeling and regulation of gene expression. | ||||||
