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

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

All-trans retinoic acid (ATRA) plays key roles in neurogenesis mediated by retinoic acid receptors (RARs). RARs are important targets for the therapeutic regulation of neurogenesis but effective drug development depends on modelling-based strategies to design high-specificity ligands in combination with

Molecular bioSystems, 5(5), 458-471 (2009-04-22)
The natural retinoid, all-trans retinoic acid (ATRA), is widely used to direct the in vitro differentiation of stem cells. However, substantial degradation and isomerisation of ATRA in response to UV-vis light has serious implications with regard to experimental reproducibility and
