SB-431542 is a selective and potent inhibitor of activin receptor-like kinase (ALK, the TGF-β type I receptor), specifically

ALK4, ALK5 (IC50 = 94 nM) and ALK7. It has no effect on the other, more divergent ALK family members that recognize

bone morphogenetic proteins (BMPs) such as ALK2, ALK3 or ALK6. It has also no effect on components of the ERK, JNK,

or p38 MAP kinase pathways or on components of the signaling. SB431542 specifically blocks Smad signaling and

suppresses renewal in embryonic and induced pluripotent stem (iPS) cells and promotes differentiation. SB431542 could

enhance reprogramming efficiency when using it with MEK inhibitor PD0325901.

Product Name: Spautin-1 | Autophagy inhibitor (#C3430)

Spautin-1 is a specific and potent autophagy inhibitor (IC50=0.74µM). It promotes the degradation of Vps34 PI3 kinase

complexes by inhibiting two ubiquitin specific peptidases, USP10 and USP13, that target the Beclin1 subunit of Vps34

complexes. Since USP10 mediates the deubiquitination of p53, regulating deubiquitination activity of USP10 and USP13 by

Beclin1 provides a mechanism for Beclin1 to control the levels of p53. By this mechanism, Spautin-1 increased cancer cell

death in the setting of nutrient deprivation when autophagy would normally act as a survival mechanism in these

metabolically stressed cells.

Product Name: Trichostatin A (TSA) | HDAC inhibitor (#C8742)

클릭하시면 닫힙니다.이미지 저장을 원하시면 마우스 오른쪽클릭후 '다른이름으로 저장'을 하세요


Trichostatin A (TSA) is a potent histone deacetylase (HDAC) inhibitor. It inhibits HDAC 1, 2, 3, 6, 10, 11 at IC50s of less than

10 nM, with over 300-fold selectivity against class IIa HDACs.[1] TSA affects DNA replication and gene expression by

inhibiting HDAC activity and therefore altering the histone modifications and access of DNA inside chromatin.

Trichostatin A induces apoptosis and cell growth arrest at both G and G/M phases. As HDACs are overexpressed in many

cancer types, TSA is widely used to probe the tumorigenesis mechanism targeting HDAC.[2] Trichostatin A was found to

prevent the differentiation of embryonic stem cell,[3] while TSA treatment increased functional characteristics of human

ESC/iPSC-derived cardiomyocytes.[4]

Wnt-C59 was first disclosed in patent WO2010101849 as a potent Wnt signaling modulator. It has IC50 less than 0.11 nM

in Wnt-Luc reporter assay for Wnt pathway inhibition. In the study, Wnt-C59 prevents palmitylation of Wnt proteins by

Porcupine (Porcn, a membrane-bound O-acyltransferase), thereby blocking Wnt secretion and activity, similar to Wnt

inhibitors IWP-2, IWP-3 and IWP-4. But Wnt-C59 is more potent and selective, and has better chemical/physical properties,

suitable for in vitro/in vivo studies.

Y-27632 is widely used as a specific inhibitor of the Rho-associated coiled-coil forming protein serine/threonine kinase

(ROCK) family. It has been found to prevent dissociation-induced apoptosis in human embryonic stem cells and enhance

the survival and cloning efficiency of dissociated hES cells without affecting their self-renewal properties or pluripotency.

Y-27632 can also enhance survival during the transplantation of ES cell-derived neural precursors.
