SAFit2 is a highly potent and selective inhibitor of fk506 binding protein 51 (FKBP51) with a Ki value of 6 nM. SAFit2 can enhance the binding of AKT2-AS160 and participate in the downstream response of glucocorticoid release in vivo. It is a candidate compound for the treatment of obesity, chronic pain, depression and anxiety.

alphaSYN-IN-NAB2, a neuron-protective agent, is a protein encoded by the NAB2 gene. NAB2 effectively and selectively protects a variety of cells from alpha-SYN toxicity. NAB2 promotes endosomal transport dependent on E3 ubiquitin ligase Rsp5/Nedd4. NAB2 identifies a viable molecular node in alpha-SYN biology that corrects multiple aspects of its underlying pathology, including dysfunctional endosomes and endoplasmic reticulum to Golgi vesicles transport. NAB2 is involved in cellular processes such as cell differentiation, apoptosis and stress response, and can be used to study cancer, neurodevelopment and neuronal activity.

Crebinostat is a potent histone deacetylase (HDAC) inhibitor, targeting HDAC1, HDAC2, HDAC3, and HDAC6 with IC50s of 0.7 nM, 1.0 nM, 2.0 nM, and 9.3 nM, respectively. It increases the density of synapsin-1 punctae along dendrites in neurons in vitro, modulates chromatin-mediated neuroplasticity, and enhances memory in mice. Additionally, Crebinostat induces histone H3 and H4 acetylation and enhances the expression of Egr1, a cAMP-responsive element binding protein (CREB) target gene.

MKK7-COV-9 is a selective and potent covalent inhibitor of MKK7 with inhibitory effects on MKK7-induced protein-protein interactions.MKK7-COV-9 interrupts the activation of primary B-cells in response to LPS.MKK7-COV-9 shows low cytotoxicity at high concentrations.

Tacrolimus monohydrate (LCP-Tacro) is a macrolide from the culture broth of a strain of Streptomyces tsukubaensis, binds to FK506 binding protein (FKBP) to form a complex. Tacrolimus inhibits calcineurin phosphatase, which inhibits T-lymphocyte signal transduction and IL-2 transcription. Immunosuppressive properties. It prevents the activation of T-lymphocytes in response to antigenic or mitogenic stimulation in vitro and has strong immunosuppressive activity in vivo.

5-Hydroxy-1-methylhydantoin (HD-003) is an antioxidant potentially for the treatment of renal failure. A creatinine metabolite, 5-Hydroxy-1-methylhydantoin , a hydroxyl radical scavenger, has previously been shown to confer renoprotection by inhibiting the progression of chronic kidney disease in rats. 5-Hydroxy-1-methylhydantoin is a novel anti-oxidant drug completely suppressed the expression of B2-kinin receptors (B2KR) in response to high glucose (25 mM) stimulation in VSMC and was also shown to attenuate the effects of BK on VSMC remodeling. 5-Hydroxy-1-methylhydantoin inhibited the BK-induced increase in MAPK phosphorylation and attenuated the increase in connective tissue growth factor (CTGF) protein levels in VSMC. These findings suggest that 5-Hydroxy-1-methylhydantoin may confer vascular protection against high glucose concentrations and BK-stimulation to ameliorate vascular injury and remodeling through its anti-oxidant properties.

VH-298 is a potent inhibitor of VHL that stabilizes HIF-α and elicits a hypoxic response via a different mechanism, that is the blockade of the VHL:HIF-α protein-protein interaction downstream of HIF-α hydroxylation by PHD enzymes.

CCI-006, a selective inhibitor and chemosensitizer for MLL-rearranged leukemia cells, disrupts mitochondrial respiration. This action leads to irreversible mitochondrial depolarization and triggers a pro-apoptotic unfolded protein response in specific MLL-r leukemia cells.

HIF-2a translation inhibitor is a potent HIF-2α translation inhibitor with IC50=5 μM that inhibits constitutive and hypoxia-induced HIF-2α protein expression. Among them, HIF-2α-IN-4 associates the 5'UTR iron response element with oxygen sensing.
