IWP-2 is a Wnt pathway inhibitor (IC50=27 nM) and an ATP-competitive CK1δ inhibitor (IC50=40 nM for M82FCK1δ). IWP-2 inhibits self-renewal of embryonic stem cells and has been used in stem cell and organoid research.

DJ001 is a highly specific, selective, and non-competitive protein tyrosine phosphatase σ (PTPσ) inhibitor with an IC50 of 1.43 μM, and it promotes the regeneration of hematopoietic stem cells.

GSK-3484862 is a non-covalent Dnmt1 inhibitor that induces DNA hypomethylation, offering potential therapeutic benefits against cancer.

Stemazole is a novel small molecule human stem progenitor cell proliferation activator that promotes the survival of human embryonic stem cells and maintains stemness, and promotes the survival of oligodendrocyte precursor cells in vitro. Stemazole significantly increased cell survival and clone formation in a dose-dependent manner, reduced apoptosis, and promoted recovery of motor dysfunction and myelin repair. Stemazole can be used as a therapeutic agent in demyelinating disorders, promoting OPC survival in vitro and regeneration in vivo.

BPDA2 is a highly selective and competitive SHP2 inhibitor, exhibiting IC50 values of 92.0 nM for SHP2, and 33.39 μM and 40.71 μM for SHP1 and SHP1B, respectively. This compound effectively downregulates mitogenic and cell survival signaling, including reducing expression of receptor tyrosine kinases (RTKs). Furthermore, BPDA2 suppresses SHP2-mediated signaling, leading to the inhibition of breast cancer cell phenotypes [1].

Diclofenac (Diclofenacum) is a nonsteroidal benzeneacetic acid derivative with anti-inflammatory activity. Diclofenac binds and chelates both isoforms of cyclooxygenase (COX-1 and-2), thereby blocking the conversion of arachidonic acid to pro-inflammatory-proprostaglandins.

Diclofenac Diethylamine, a non-selective COX inhibitor, is utilized as a nonsteroidal anti-inflammatory drug (NSAID).

Benzyl butyl phthalate (1,2-benzenedicarboxylic acid) is used as a plasticizer for PVC.

Estradiol (E2) is a naturally occurring steroidal sex hormone that is essential for female fertility and maintenance of secondary sexual characteristics. Estradiol upregulates IL-6 expression through estrogen receptor beta (ERβ).

Bestatin (Ubenimex) competitively inhibits many aminopeptidases, including B, N and leucine aminopeptidases. Ubenimex is a microbial metabolite and dipeptide with potential immunomodulatory and antitumor activities. Aminopeptidases has been implicated in the process of cell adhesion and invasion of tumor cells. Therefore, inhibiting aminopeptidases may partially attribute to the antitumor effect of ubenimex. This agent also activates T lymphocyte, macrophage, and bone marrow stem cell as well as stimulates the release of interleukin-1 and -2, thus further enhances its antitumor activity.

Diclofenac sodium (GP 45840) is a non-steroidal anti-inflammatory agent (NSAID) with antipyretic and analgesic actions. It is primarily available as the sodium salt.

Plerixafor (AMD-3329), a chemokine receptor antagonist, blocks the binding of stromal cell-derived factor (SDF-1alpha) to the cellular receptor CXCR4.

L-ascorbic acid 2-phosphate (Vitamin C phosphate) is a stable and long-lasting vitamin C derivative that stimulates collagen formation and has potential antioxidant capacity. L-ascorbic acid 2-phosphate is commonly used to promote osteogenic differentiation of human adipose stem cells (hASCs) in cell culture by increasing alkaline phosphatase (ALP) activity and runt-related transcription factor-2-DNA(runx2A) expression.

β-Glycerophosphate is a classical serine-threonine phosphatase inhibitor used in kinase reaction buffers. BGP is often used in combination with other phosphatase protease inhibitors for broad spectrum inhibition. It functions as an organic phosphate donor

Diclofenac Potassium (CGP-45840B) is a nonsteroidal anti-inflammatory drug taken to reduce inflammation and as an analgesic reducing pain in certain conditions.

CHIR-99021 HCl (Laduviglusib HCl) is a highly potent and selective inhibitor of GSK-3α β, with IC50 values of 10 nM and 6.7 nM respectively. It demonstrates remarkable selectivity for GSK-3, with over 500-fold selectivity over CDC2, ERK2, and other protein kinases. Additionally, CHIR-99021 HCl serves as a robust activator of the Wnt β-catenin signaling pathway. Moreover, it exhibits the ability to enhance self-renewal in both mouse and human embryonic stem cells. Furthermore, CHIR-99021 HCl induces autophagy [1] [2] [3].

Pifithrin-β hydrobromide (Cyclic PFT-α) is an inhibitor of p53; reversibly blocks p53-dependent transcriptional activation and apoptosis. Protects against neuronal death in models of stroke and neurodegenerative disorders. Active in vivo; protects mice from the side-effects of Y therapy associated with p53 induction. Supresses self-renewal of embryonic stem cells. Also aryl hydrocarbon receptor (AHR) agonist, causes upregulation of AHR target gene CYP1A1 (EC50 = 1.1 μM).

Ginsenoside F2 has antiproliferative activity against breast cancer stem cells (CSCs). It induces apoptosis in breast CSCs by activating the intrinsic apoptotic pathway and mitochondrial dysfunction.
