Valproic acid sodium salt (Sodium Valproate) is the sodium salt form of valproic acid with anti-epileptic activity. Valproic acid sodium salt is converted into its active form, valproate ion, in blood. Although the mechanism of action remains to be elucidated, Valproic acid sodium salt increases concentrations of gamma-aminobutyric acid (GABA) in the brain, probably due to inhibition of the enzymes responsible for the catabolism of GABA. This potentiates the synaptic actions of GABA. Valproic acid sodium salt may also affect potassium channels, thereby creating a direct membrane-stabilizing effect.

Lenalidomide (CC-5013) is an immunomodulator with oral activity. Lenalidomide is a ligand for the ubiquitin E3 ligase cereblon (CRBN), which selectively ubiquitinates and degrades two lymphoid transcription factors, IKZF1 and IKZF3, via the CRBN-CRL4 ubiquitin ligase, and is commonly used in the synthesis of PROTAC products.

Divalproex Sodium (Valproate semisodium) binds to and inhibits gamma-aminobutyric acid (GABA) transaminase and its anticonvulsant activity may be exerted by increasing brain concentration of GABA and by inhibiting enzymes that catabolize GABA or block the reuptake of GABA into glia and nerve endings. It also is an HDAC inhibitor, Comprised of sodium valproate and valproic acid with anticonvulsant and antiepileptic activities. Divalproex may also work by suppressing repetitive neuronal firing through the inhibition of voltage-sensitive sodium channels.

Dicyclanil is an insect growth regulator with a chemical structure similar to that of cyclopromazine.

TCH-165 is a small molecule modulator of proteasome assembly, resulting in an increase in 20S levels. The increase in the level of free 20S corresponds to enhanced proteolysis of IDPs.

Lenalidomide hemihydrate is a derivative of Thalidomide, an orally active immunomodulator that acts as a molecular gel. It is a ligand for the ubiquitin E3 ligase cereblon, which selectively ubiquitinates and degrades two lymphoid transcription factors, IKZF1 and IKZF3, via the CRBN-CRL4 ubiquitin ligase.

4-Chlorocatechol, a significant degradation product of 4-chloro-2-aminophenol (4C2AP), serves as a substrate for both catechol 1,2-dioxygenases and chlorocatechol dioxygenase [1] [2].

Obatoclax Mesylate (GX15-070) is a Bcl-2 antagonist (Ki: 0.22 μM) and can induce apoptosis with up-regulation of Bim, induced cytochrome c release, and activation of caspase-3.

MID-1 is an inhibitor of MG53-IRS-1 (Mitsugumin 53-Insulin Receptor Substrate-1) interaction. It disrupts molecular association of MG53 with IRS-1 and abolishes MG53-induced IRS-1 ubiquitination and degradation in skeletal muscle, leading to elevated IRS-1 expression level and increased insulin signaling and glucose uptake

Orlistat degradation product is a degradation product of the digestive lipase inhibitor orlistat . It is formed via hydrolytic and thermal degradation as well as digestion by human carboxyl ester lipase.

PROTAC TYK2 Degradation Agent1 is a potent, subtype-selective degrader of TYK2, exhibiting degradation activity with a DC50 of 14 nM. It is utilized in autoimmune disease research [1].

Valproic Acid (2-Propylpentanoic Acid) is an HDAC inhibitor that suppresses HDAC1 activity and induces HDAC2 degradation, exhibiting oral bioavailability. Valproic Acid activates Notch1 signalling and inhibits the proliferation of small cell lung carcinoma cells, making it applicable for research into epilepsy and bipolar disorder.

Penicillamine (Artamine), possessing antineoplastic properties, induces apoptosis by a p53-mediated mechanism and inhibits angiogenesis by chelating with copper, a cofactor for angiogenesis. Artamine is a beta dimethyl analog of the amino acid cysteine. As a degradation product of penicillin antibiotics, Artamine chelates with heavy metals and increases their urinary excretion.

JSH-23 is an NF-κB inhibitor that inhibits NF-κB transcriptional activity (IC50=7.1 μM) but does not affect IκBα degradation. JSH-23 is an antioxidant with anti-inflammatory activity.

AK-1690 is a potent and selective STAT6 PROTAC degrader that induces degradation of STAT6 proteins in cells (DC50=1 nM) and depletes STAT6 proteins in mouse tissues, which can be used in cancer research.

AU-15330 is a proteolytic targeting chimera (PROTAC) that simultaneously targets SMARCA4, SMARCA2, and PBRM1 for degradation and exhibits cytotoxicity in H3.3K27M cells but not in H3 wild-type cells. [2]

Bafilomycin A1 belongs to the macrolide class of antibiotics and is a V-ATPase inhibitor (IC50=0.44 nM) that is specific and reversible. Bafilomycin A1 is an inhibitor of the late phase of autophagy, blocking the fusion of autophagosomes with lysosomes. Bafilomycin A1 also induces apoptosis.

AOH1996 is an orally active ligand for the replicasome component PCNA (proliferating cell nuclear antigen), targeting the transcription-replication conflict (TRC). It interferes with the interaction of PCNA with its binding proteins, leading to DNA replication stress and apoptosis. AOH1996 causes proteasome-dependent rpb1 degradation and lethal DNA damage by stabilizing the interaction between PCNA and RNA polymerase II, and acts synergistically with DNA damaging agents to inhibit tumor cell growth.
