Cell experiment: | Cells (10,000/cm2) are seeded in complete medium and allowed to attach overnight. The cells are then shifted to defined medium (DM), allowed to equilibrate for 24 h, and treatment is initiated by addition of fresh DM or DM containing epidermal growth factor (EGF) or retinoid. After 3 days of daily treatment with retinoid, the cells are harvested with 0.025% trypsin, 1 mM EDTA, fixed in isotonic buffer containing 4% formaldehyde, and counted using a counter[2]. |
Animal experiment: | Mice (n=6) are treated topically on the dorsal skin with vehicle (92.5% acetone/7.5% DMSO), 0.072 μmol/kg of TTNPB, 1.15 μmol/kg of AGN 193109, or 0.072 μmol/kg of TTNPB plus 0.072, 0.288, or 1.15 μmol/kg of AGN 193109 for 5 days. Mice are euthanized on Day 8[3]. |

AGN 193109 is a retinoid analog, and acts as a specific and highly effective antagonist of retinoic acid receptors (RARs), with Kds of 2 nM, 2 nM, and 3 nM for RARα, RARβ, and RARγ, respectively.
AGN 193109 is a highly effective antagonist of retinoic acid receptors, with Kds of 2 nM, 2 nM, and 3 nM for RARα, RARβ, and RARγ, respectively. AGN 193109 is completely RAR specific, because it does not bind to or transactivate through any of the RXRs[1]. AGN 193109 (100 nM) inhibits the TTNPB (a retinoic acid receptor agonist)-dependent morphological change in ECE16-1 cells. AGN193109 half-reverses retinoid-dependent growth suppression at 10 nM, and completely shows this effect at 100 nM in ECE16-1 cells. AGN193109 (100 nM) also eliminates TTNPB-induced decrease in levels of K5, K6, K14, K16, and K17 and increase in levels of K7, K8, and K19[2].
AGN 193109 (1.15 μmol/kg) does not causes overt toxicity and has no effect on spleen weight on the mice, but it suppresses TTNPB-induced increase in spleen weight of the mice. AGN 193109 also significantly reduces the cutaneous toxicity induced by ATRA. AGN 193109 (0.30 or 1.20 μmol/kg) by topical treatment significantly reduces both weight loss and cutaneous toxicity caused by oral TTNPB cotreatment[3].

The synthetic retinoid AGN 193109 but not retinoic acid elevates CYP1A1 levels in mouse embryos and Hepa-1c1c7 cells
Toxicol Appl Pharmacol 2001 Jul 15;174(2):153-9.PMID:11446831DOI:10.1006/taap.2001.9209.
The synthetic retinoid AGN 193109 is a potent pan retinoic acid receptor (RAR) antagonist. Treatment of pregnant mice with a single oral 1 mg/kg dose of this antagonist on day 8 postcoitum results in severe craniofacial (median cleft face or frontonasal deficiency) and eye malformations in virtually all exposed fetuses. Using differential display analysis, we have determined that CYP1A1 mRNA levels are elevated in mouse embryos 6 h following treatment with AGN 193109. Similarly, an elevation in CYP1A1 mRNA levels, protein levels, and aryl hydrocarbon hydoxylase activity occurs in Hepa-1c1c7 cells, with the maximal elevation observed when the cells were treated with 10(-5) M AGN 193109 for 4 to 8 h. Elevation in CYP1A1 mRNA levels in mouse embryos and Hepa-1c1c7 cells does not occur upon treatment with the natural retinoid, all-trans-retinoic acid. Finally, elevation in CYP1A1 mRNA levels was not observed when mutant Hepa-1c1c7 cells, which are defective in either the aryl hydrocarbon receptor (AhR) or aryl hydrocarbon receptor nuclear translocator (ARNT), were treated with AGN 193109. This suggests that the AhR/ARNT pathway and not the RAR/RXR pathway is mediating the elevation of CYP1A1 mRNA levels by AGN 193109, at least in the Hepa-1c1c7 cells. This is the first example of a retinoid that displays the abililty to regulate both the RAR/RXR and AhR/ARNT transcriptional regulatory pathways.
Cell type and gene-specific activity of the retinoid inverse agonist AGN 193109: divergent effects from agonist at retinoic acid receptor gamma in human keratinocytes
Cell Growth Differ 1999 Apr;10(4):255-62.PMID:10319995doi
Retinoids are important regulators of epithelial differentiation. AGN 193109 is a high-affinity antagonist and inverse agonist for the nuclear retinoic acid receptors (RARs). Paradoxically, both AGN 193109 and retinoid agonists inhibit the expression of the differentiation marker MRP-8 in normal human keratinocytes (NHKs). TTNPB, an RAR agonist, and AGN 193109 mutually antagonize MRP-8 inhibition at both mRNA and protein levels. We find that this antagonism, which is greatest at an AGN 193109:TTNPB ratio of about 10:1, is absent when either compound is in significant excess. The potent RARalpha-specific agonist, AGN 193836, has no effect on MRP-8 regulation. These data indicate that inverse agonists and agonists suppress MRP-8 in NHKs through RARgamma using distinct and mutually inhibitory mechanisms. The activity of AGN 193109 on MRP-8 is cell type specific. In differentiating ECE16-1 cervical cells, TTNPB inhibits while AGN 193109 induces MRP-8 mRNA levels. The effect of AGN 193109 on genes inhibited by retinoid agonists in NHKs is also selective; expression of the differentiation markers transglutaminase 1 and keratin 6 is not down-regulated by AGN 193109 whereas stromelysin-1 expression is suppressed. These results show a complex gene and cell context-specific interplay between agonist and inverse agonist for the regulation of gene expression.
Specific antagonist of retinoid toxicity in mice
Toxicol Appl Pharmacol 1996 May;138(1):169-75.PMID:8658506DOI:10.1006/taap.1996.0110.
AGN 193109 was recently identified as a potent retinoic acid receptor (RAR) antagonist in vitro. The purpose of the present study was to determine if AGN 193109 functions as an RAR antagonist in vivo and thus could prevent and/or treat retinoid toxicity. Female hairless mice were treated topically for 5 consecutive days with the synthetic retinoic acid receptor agonist (E)-4-[2-(5,6,7,8- tetrahydro-5,5,8,8-tetramethyl-2-naphthyl)propen-1-yl]benzoic acid (TTNPB) alone or in the presence of a 1-, 4-, or 16-fold molar excess of AGN 193109. TTNPB caused skin flaking, skin abrasions, and splenomegaly, and these effects were blocked in a dose-dependent fashion by AGN 193109 cotreatment. In the same model, AGN 193109 also decreased topical irritation induced by the natural RAR agonist, all-trans-retinoic acid. To determine if topical AGN 193109 could block toxicity induced by an oral retinoid, mice were treated by gavage with TTNPB (0.75 mumol/kg/day) and topically with 0, 0.3, or 1.2 mumol/kg/day of AGN 193109 for 4 days. TTNPB treatment alone caused cutaneous irritation and weight loss, and these effects were inhibited by AGN 193109 cotreatment. To determine if AGN 193109 could be used to treat preexisting retinoid toxicity, mice were pretreated topically on Days 1-2 with TTNPB (0.72 mumol/kg/day) and then treated topically on Days 3-5 with 0, 1.44, 7.2, or 36.0 mumol/kg of AGN 193109. TTNPB pretreatment caused precipitous weight loss and, in the absence of AGN 193109 intervention, 60% mortality. AGN 193109 treatment at all dose levels significantly accelerated recovery of body weight and prevented death in TTNPB-intoxicated mice. These data demonstrate that AGN 193109 is a potent RAR antagonist and a potential antidote of retinoid intoxication in vivo. In addition to potential clinical applications in the prevention and treatment of retinoid toxicity, AGN 193109 should provide a powerful experimental tool for the elucidation of retinoid biology.
High affinity retinoic acid receptor antagonists: analogs of AGN 193109
Bioorg Med Chem Lett 1999 Feb 22;9(4):573-6.PMID:10098666DOI:10.1016/s0960-894x(99)00047-5.
A series of high affinity retinoic acid receptor (RAR) antagonists were prepared based upon the known antagonist AGN 193109 (2). Introduction of various phenyl groups revealed a preference for substitution at the para-position relative to the meta-site. Antagonists with the highest affinities for the RARs possessed hydrophobic groups, however, the presence of polar functionality was also well tolerated.
All-trans retinoic acid enhances the long-term repopulating activity of cultured hematopoietic stem cells
Blood 2000 Jan 15;95(2):470-7.PMID:10627451doi
The retinoic acid receptor (RAR) agonist, all-trans retinoic acid (ATRA), is a potent inducer of terminal differentiation of malignant promyelocytes, but its effects on more primitive hematopoietic progenitors and stem cells are less clear. We previously reported that pharmacologic levels (1 micromol) of ATRA enhanced the generation of colony-forming cell (CFC) and colony-forming unit-spleen (CFU-S) in liquid suspension cultures of lin- c-kit+ Sca-1+ murine hematopoietic precursors. In this study, we further investigated the effects of ATRA as well as an RAR antagonist, AGN 193109, on the generation of transplantable cells, including pre-CFU-S, short-term repopulating stem cells (STRCs), and long-term repopulating stem cells (LTRCs). ATRA enhanced the ex vivo maintenance and production of competitive repopulating STRCs and LTRCs from lin- c-kit+ Sca-1+ cells cultured in liquid suspension for 14 days. In addition, ATRA prevented the differentiation of these primitive stem cells into more mature pre-CFU-S during the 14 days of culture. In marked contrast, lin- c-kit+ Sca-1+ cells cultured with AGN 193109 for 7 days had virtually no short- or long-term repopulating ability, but displayed an approximately 6-fold increase in the pre-CFU-S population. The data suggest that the RAR agonist ATRA enhances the maintenance and self-renewal of short- and long-term repopulating stem cells. In contrast, the RAR antagonist AGN 193109 abrogates reconstituting ability, most likely by promoting the differentiation of the primitive stem cells. These results imply an important and unexpected role of retinoids in regulating hematopoietic stem cell differentiation. (Blood. 2000;95:470-477)
