Cancer Stem Cells
Cancer stem cells (CSCs) are populations of cancer cells that have the properties of stem cells i.e. self-renewal and ability to generate differentiated progenies. CSCs have high plasticity, which changes their phenotypic and functional appearance. They have important roles in tumor development, expansion, resistance, relapse and metastasis. Multiple studies have shown that CSCs originate from non-malignant stem or progenitor cells. Inhibition of developmental signaling pathways that are critical for stem and progenitor cell homeostasis and function has important implications in strategies to target CSCs in cancer research.
Studies have shown that CSCs develop several mechanisms to protect themselves from toxins and genotoxic stress, including enhanced DNA damage repair capacity, increased expression of drug transporters, maintenance of a low reactive oxygen species (ROS) environment, and recruitment of a protective niche. Therefore, targeting signaling pathways that are required to maintain stem cells is the current therapeutic strategy for CSCs. For example, hedgehog pathway, Notch and Wnt signaling pathways.
Newly developed drugs targeting surface markers of CSCs opens the new avenues for cancer therapy, such as CD44, CD133, EpCAM, Sox2, and Oct-3/4.

LDN193189 Tetrahydrochloride (Standard)
0 ImagesSynonyms: DM-3189 Tetrahydrochloride (Standard)LDN193189 (DM-3189) Tetrahydrochloride (Standard) is the analytical standard of LDN193189 Tetrahydrochloride (HY-12071A). This product is intended for research and analytical applications. LDN193189 (DM-3189) Tetrahydrochloride is a potent selective BMP type I receptor (BMP I) inhibitor. LDN193189 efficiently inhibits transcriptional activity of the BMP type I receptors ALK2 and ALK3 with IC50 values of 5 nM and 30 nM, respectively. LDN193189 can be used for the research of bone morphogenetic protein signalling, such as fibrodysplasia ossificans progressiva.

Avatrombopag maleate (Standard)
0 ImagesSynonyms: AKR-501 maleate (Standard); E5501 maleate (Standard); YM477 maleate (Standard)Avatrombopag (maleate) (Standard) is the analytical standard of Avatrombopag (maleate). This product is intended for research and analytical applications. Avatrombopag maleate (AKR-501) is an orally active, nonpeptide thrombopoietin (TPO) receptor agonist (EC50=3.3 nM). Avatrombopag maleate mimics the biological activities of TPO. Avatrombopag maleate increases platelet production by activating the intracellular signaling system, and promotes production of platelets and megakaryocytes from hemopoietic precursor cells. Avatrombopag maleate is a substrate of cytochrome P450 (CYP) 2C9 and CYP3A.
