Biochem/physiol Actions

EC23 is a synthetic, photostable all-trans retinoic acid (ATRA) analog/mimetic that targets RAR with greater affinity than ATRA (RARα/β/γ EC50 by cell-free TR-FRET binding assay = 3.7/3.3/16.8 with EC23 vs. 16.0/17.6/14.7 nM with ATRA) and does not bind retinoid x receptors (RXRs). EC23 induces differentiation of human pluripotent embryonic stem cells (0.1-10 μM) with a similar or better efficiency than ATRA.

All trans-retinoic acid (ATRA) is widely used to direct the differentiation of cultured stem cells. When exposed to the pluripotent human embryonal carcinoma (EC) stem cell line, TERA2.cl.SP12, ATRA induces ectoderm differentiation and the formation of neuronal cell types. We

Two chalcone derivatives, xanthoangelol (1) and 4-hydroxyderricin (II) isolated from Angelica keiskei Koidzumi, inhibited pig gastric H+, K(+)-ATPase with IC50 values of 1.8 and 3.3 microM, respectively. The inhibition by I or II was competitive with respect to ATP and

Persistent infection of hepatitis C virus (HCV) is one of the leading causes of end-stage liver disease (ESLD), such as decompensated cirrhosis and liver cancer. Of particular note, nearly half of HCV-infected people in the United States are reported to

All-trans-retinoic acid (ATRA) and its associated analogues are important mediators of cell differentiation and function during the development of the nervous system. It is well known that ATRA can induce the differentiation of neural tissues from human pluripotent stem cells.
Kirsty E Clarke et al.
Neurochemistry international, 106, 74-84 (2016-12-25)
The inability of neurites to grow and restore neural connections is common to many neurological disorders, including trauma to the central nervous system and neurodegenerative diseases. Therefore, there is need for a robust and reproducible model of neurite outgrowth, to
