KU-32 is a novel, novobiocin-based Hsp90 inhibitor that can protect against neuronal cell death.
Palmitic acid-d17 is the deuterium labeled Palmitic acid. Palmitic acid is a long-chain saturated fatty acid commonly found in both animals and plants. PA can induce the expression of glucose-regulated protein 78 (GRP78) and CCAAT/enhancer binding protein homologous protein (CHOP) in in mouse granulosa cells[1][2].
Vibsanin A, a protein kinase C (PKC) activator, exhibits anti-proliferative activity against human cancer cell lines. Vibsanin A is also a HSP90 inhibitor[1].
MAO A/HSP90-IN-1 (4-b) is a MAO A/HSP90 dual inhibitor with IC50 value of 1.77 μM and 0.019 μM in Glioblastoma (GBM) GL26 cells and HSP90α, respectively. MAO A/HSP90-IN-1 (4-b) can inhibit MAO A activity, HSP90 binding and the expression of HER2 and phospho-Akt to inhibit the growth of GBM, they also reduce PD-L1 expression, which inhibits T cell activation. MAO A/HSP90-IN-1 (4-b) have potential to inhibit tumor immune escape. MAO A/HSP90-IN-1 (4-b) can be used for brain tumor-related diseases research[1].
116-9e (MAL2-11B) is a Hsp70 co-chaperone DNAJA1 inhibitor. 116-9e inhibits Simian Virus 40 (SV40) replication and DNA synthesis. 116-9e inhibits tumor antigen (TAg)’s endogenous ATPase activity and the TAg-mediated activation of Hsp70[1][2].
HM03 trihydrochloride is a potent and selective HSPA5 (Heat shock 70kDa protein 5, also known as Bip, Grp78) inhibitor. HM03 trihydrochloride has anticancer activity[1].
VER-155008 is an inhibitor of Hsp70, with IC50s of 0.5 μM, 2.6 μM, and 2.6 μM for Hsp70, Hsc70 and Grp7, respectively, and with a Kd of 0.3 μM for Hsp70.
ML346 is an activator of Hsp70 expression and HSF-1 activity, with an EC50 of 4.6 μM for Hsp70. ML346 restores protein folding in conformational disease models, without significant cytotoxicity or lack of specificity. ML346 induces specific increases in genes and protein effectors of the heat shock response (HSR), including chaperones such as Hsp70, Hsp40, and Hsp27[1].
MPC-0767 is a potent, selective, and orally active hsp90 inhibitor. MPC-0767 is an L-alanine ester prodrug of MPC-3100 with improved chemical stability[1].
Tamoxifen-d3 is the deuterium labeled Tamoxifen[1]. Tamoxifen (ICI 47699) is an orally active, selective estrogen receptor modulator (SERM) which blocks estrogen action in breast cells and can activate estrogen activity in other cells, such as bone, liver, and uterine cells[2][3][4]. Tamoxifen is a potent Hsp90 activator and enhances the Hsp90 molecular chaperone ATPase activity. Tamoxifen also potent inhibits infectious EBOV Zaire and Marburg (MARV) with IC50 of 0.1 μM and 1.8 μM, respectively[6]. Tamoxifen activates autophagy and induces apoptosis[5]. Tamoxifen also can induce gene knockout of CreER(T2) transgenic mouse[7].
PU-WS13 is a selective Grp94 inhibitor, with an EC50 of 0.22 μM.
Chetomin, an active component of Chaetomium globosum, is a heat shock protein 90/hypoxia-inducible factor 1 alpha (Hsp90/HIF1α) pathway inhibitor. Chetomin is a potent, nontoxic non-small cell lung cancer cancer stem cells (NSCLC CSC)-targeting molecule[1].
Novobiocin (Albamycin) is a potent and orally active antibiotic. Novobiocin also is a DNA gyrase inhibitor and a heat shock protein 90 (Hsp90) antagonist. Novobiocin has the potential for the research of highly beta-lactam-resistant pneumococcal infections. Novobiocin shows anti-orthopoxvirus activity[1][2][3][4][6].
Palmitic acid-d2-5 is the deuterium labeled Palmitic acid. Palmitic acid is a long-chain saturated fatty acid commonly found in both animals and plants. PA can induce the expression of glucose-regulated protein 78 (GRP78) and CCAAT/enhancer binding protein homologous protein (CHOP) in in mouse granulosa cells[1][2].
