Mifepristone (C-1073) is a Progestin Antagonist. The mechanism of action of mifepristone is as a Progestational Hormone Receptor Antagonist.

Epiandrosterone (EpiA) is a dehydroepiandrosterone metabolite and a precursor of testosterone and estradiol with hypolipidemic and anabolic property.

PR-619 (2,6-Diamino-3,5-dithiocyanopyridine) is a DUB inhibitor that inhibits USP2 4 5 7 8 (EC50=7.2 3.93 8.61 6.86 4.9 μM). PR-619 induces endoplasmic reticulum stress and activates autophagy.

PR-924 is a selective inhibitor of tripeptide epoxyketone immunoproteasome subunit LMP-7 (IC50: 22 nM). PR-924 inhibits growth and triggers apoptosis in multiple myeloma (MM) cells. PR-924 has antitumor activities. PR-924 covalently modifies proteasomal N-terminal threonine active sites.

PR-104A is a hypoxia-targeted anticancer agent.

PR-104 sodium is a hypoxia-activated DNA cross-linking agent used in the research of tumor xenograft models. It functions as a nitrogen mustard pre-prodrug and efficiently transforms into the more lipophilic dinitrobenzamide mustards alcohol PR-104A.

PR 39 (porcine) acetate is a noncompetitive, reversible and allosteric proteasome inhibitor. PR 39 (porcine) acetate reversibly binds to the α7 subunit of the proteasome and blocks degradation of NF-κB inhibitor IκBα by the ubiquitin-proteasome pathway.

PR-104 is a highly specific hypoxia-activated agent that cross-links DNA, enabling its application in various tumor xenograft models. Functioning as a pre-prodrug of nitrogen mustard, PR-104 undergoes efficient conversion to the dinitrobenzamide mustards alcohol form, known as PR-104A[1].

Antibacterial peptide. Stimulates angiogenesis and inhibits inflammatory responses by selectively blocking proteasome degradation of IκBα.

This peptide is an H2-Db-restricted epitope from the Influenza A/PR/8/34 nucleoprotein.

PR825 is a β5c inhibitor with IC50 = 20 nM

PR-39 TFA, a natural peptide rich in proline and arginine with antibacterial properties, acts as a noncompetitive, reversible, and allosteric inhibitor of the proteasome. It specifically attaches to the α7 subunit of the proteasome, preventing the degradation of the NF-κB inhibitor IκBα through the ubiquitin-proteasome pathway. Additionally, PR-39 TFA promotes angiogenesis, suppresses inflammatory responses, and notably decreases myocardial infarct size in mice [1] [2].

Azelaprag (AMG 986) is an effective small-molecule apelin receptor agonist. Azelaprag can be used to treat neurological diseases and cardiovascular diseases.

Liproxstatin-1 is a potent and selective inhibitor of ferroptosis (IC50=22 nM). Liproxstatin-1 protects cells from ferroptosis induced by ferroptosis inducers (e.g., Erastin, RSL3).

Elamipretide (MTP-131) is a mitochondria-targeted antioxidant tetrapeptide (D-Arg-dimethylTyr-Lys-Phe-NH2) that reduces toxic reactive oxygen species (ROS) production and stabilizes cardiolipin, with blood-brain-barrier permeability. It is a potential therapeutic agent in the rare disease of Barnes syndrome.

O-Propargyl-Puromycin (OP-puro) is a potent protein synthesis inhibitor, a puromycin acetylene analog.

Osunprotafib (ABBV-CLS-484) is a potent, orally bioavailable PTP1B PTPN2 inhibitor in clinical trials for solid tumors. [1] Osunprotafib (ABBV-CLS-484) stimulates the tumor microenvironment and promotes natural killer cell and CD8 T cell function and enhances T cell anti-tumor immunity by enhancing JAK-STAT signaling and reducing T cell dysfunction. [2]

Avapritinib (BLU-285) is a selective, highly potent, and orally active inhibitor of KIT and PDGFRA activation loop mutant kinases, targeting KIT D816V (IC50:0.27 nM) and PDGFRA D842V (IC50:0.24 nM), and attenuates the transport functions of ABCB1 and ABCG2. It binds to the active conformation of the kinases and exhibits antitumor activity.

Ripretinib (DCC-2618) is an orally bioavailable inhibitor of (KIT) and (PDGFRA).

Aprotinin (Traskolan) is a broad-spectrum serine protease (BPTI) inhibitor that inhibits the activity of a number of different esterases and proteases. Aprotinin is an antifibrinolytic agent used to minimize hemorrhage during complex surgical procedures.

Prostaglandin E2 (PGE2) is a naturally occurring hormone involved in various physiological processes, such as smooth muscle contraction and relaxation, vasodilation and constriction, blood pressure regulation, and inflammatory regulation.

PROTAC BRD4 ligand-1, a component of Protac GNE-987, is a ligand for BRD4 and acts as an inhibitor of BET.

Valproic Acid (2-Propylpentanoic Acid) is an HDAC inhibitor that inhibits HDAC1 activity, induces HDAC2 degradation, and is orally active. Valproic Acid can be used in epilepsy and bipolar disorder research.

Proteinase K (Protease K) is a non-specific serine protease that can tolerate changes in SDS, urea, pH (4-12), salt concentration, and temperature. Proteinase K hydrolyzes a wide range of peptide bonds and is used for protein digestion.
