Synthesis of new C-25 and C-26 steroidal acids as potential ligands of the nuclear receptors DAF-12, LXR and GR.[Pubmed:28300583]
Steroids. 2017 May;121:40-46.
A new methodology to obtain C-25 and C-26 steroidal acids starting from pregnenolone is described. Construction of the side chain was achieved by applying the Mukaiyama aldol reaction with a non-hydrolytic work-up to isolate the trapped silyl enol ether with higher yields. Using this methodology we synthesized three new steroidal acids as potential ligands of DAF-12, Liver X and Glucocorticoid nuclear receptors and studied their activity in reporter gene assays. Our results show that replacement of the 21-CH3 by a 20-keto group in the side chains of the cholestane scaffold of DAF-12 or Liver X receptors ligands causes the loss of the activity.
Identification of the Clinical Candidate (R)-(1-(4-Fluorophenyl)-6-((1-methyl-1H-pyrazol-4-yl)sulfonyl)-4,4a,5,6,7,8-hexah ydro-1H-pyrazolo[3,4-g]isoquinolin-4a-yl)(4-(trifluoromethyl)pyridin-2-yl)methano ne (CORT125134): A Selective Glucocorticoid Receptor (GR) Antagonist.[Pubmed:28368581]
J Med Chem. 2017 Apr 27;60(8):3405-3421.
The nonselective glucocorticoid receptor (GR) antagonist mifepristone has been approved in the U.S. for the treatment of selected patients with Cushing's syndrome. While this drug is highly effective, lack of selectivity for GR leads to unwanted side effects in some patients. Optimization of the previously described fused azadecalin series of selective GR antagonists led to the identification of CORT125134, which is currently being evaluated in a phase 2 clinical study in patients with Cushing's syndrome.
Recruitment of bone marrow CD11b(+)Gr-1(+) cells by polymeric nanoparticles for antigen cross-presentation.[Pubmed:28317931]
Sci Rep. 2017 Mar 20;7:44691.
The objective of this study was to investigate the function of poly(lactic-co-glycolic acid) (PLGA) nanoparticles (NPs) on the activation of antigen-specific CD8(+) T cell responses via the CD11b(+)Gr(-)1(+) myeloid subpopulations in murine bone marrow (BM). PLGA NPs containing ovalbumin (OVA) were fabricated by the double-emulsion method. The CD11b(+)Gr-1(low)Ly-6C(high) and CD11b(+)Gr-1(high)Ly-6C(low) subsets from mice bone marrow were sorted and treated with the PLGA/OVA NPs, followed by co-culture with the carboxyfluorescein succinimidyl ester (CFSE)-labelled OT-I CD8(+) cells. Co-culture of OT-I CD8(+) T cells with PLGA/OVA NPs-primed CD11b(+)Gr-1(+) subsets upregulated the expression of IL-2, TNF-alpha, INF-gamma, granzyme B, and perforin, resulting in proliferation of CD8(+) T cells and differentiation into effector cytotoxic T lymphocytes (CTLs). In vivo proliferation of CFSE-labelled OT-I CD8(+) cells in response to OVA was also obtained in the animals immunized with PLGA/OVA NPs. The results presented in this study demonstrate the ability of polymeric NPs to recruit two CD11b(+)Gr(-)1(+) myeloid subsets for effective presentation of exogenous antigen to OT-I CD8(+) T cells in the context of major histocompatibility complex (MHC) class I, leading to an induction of antigen-specific cell proliferation and differentiation into effector cells.
Muscle-specific downregulation of GR levels inhibits adipogenesis in porcine intramuscular adipocyte tissue.[Pubmed:28360421]
Sci Rep. 2017 Mar 30;7(1):510.
Intramuscular adipose is conducive to good pork quality, whereas subcutaneous adipose is considered as waste in pig production. So uncovering the regulation differences between these two adiposes is helpful to tissue-specific control of fat deposition. In this study, we found the sensitivity to glucocorticoids (GCs) was lower in intramuscular adipocytes (IMA) compared with subcutaneous adipocytes (SA). Comparison of glucocorticoid receptor (GR) revealed that IMA had lower GR level which contributed to its reduced GCs sensitivity. Higher methylation levels of GR promotor 1-C and 1-H were detected in IMA compared with SA. GR expression decrease was also found in adipocytes when treated with muscle conditioned medium (MCM) in vitro, which resulted in significant inhibition of adipocytes proliferation and differentiation. Since abundant myostatin (MSTN) was detected in MCM by ELISA assay, we further investigated the effect of this myokine on adipocytes. MSTN treatment suppressed adipocytes GR expression, cell proliferation and differentiation, which mimicked the effects of MCM. The methylation levels of GR promotor 1-C and 1-H were also elevated after MSTN treatment. Our study reveals the role of GR in muscle fiber inhibition on intramuscular adipocytes, and identifies myostatin as a muscle-derived modulator for adipose GR level.
GR159897, a potent non-peptide antagonist at tachykinin NK2 receptors.[Pubmed:7713168]
Eur J Pharmacol. 1995 Jan 16;272(2-3):241-8.
GR159897 ((R)-1-[2-(5-fluoro-1H-indol-3-yl)ethyl]-4-methoxy-4- [(phenylsulfinyl)methyl]piperidine) is a novel, highly potent and selective non-peptide antagonist at tachykinin NK2 receptors. GR159897 inhibited binding of the NK2 receptor antagonist radioligand [3H]cyclohexylcarbonyl-Gly-Ala-(D)Trp-Phe-NMe2 ([3H]GR100679) to human ileum NK2 receptors transfected into Chinese hamster ovary cells (pKi 9.5) and to rat colon membranes (pKi 10.0). GR159897 was a competitive antagonist of contractions induced by the NK2 receptor agonist [Lys3,Gly8-R-gamma-lactam-Leu9]neurokinin A-(3-10) (GR64349) in guinea-pig trachea (pA2 8.7), and had negligible activity at human NK1 receptors transfected into Chinese hamster ovary cells (pKi 5.3), NK1 receptors in guinea-pig trachea (pKB < 5) or NK3 receptors in guinea-pig cerebral cortex (pKi < 5). In vivo, in the anaesthetised guinea-pig, GR159897 (0.12 mg.kg-1 i.v.) potently antagonised bronchoconstriction induced by GR64349 (dose-ratio = 28), with a long duration of action (3 h). GR159897 should be a useful tool for studying the physiological and pathophysiological role of tachykinin NK2 receptor activation.
The anxiolytic-like activity of GR159897, a non-peptide NK2 receptor antagonist, in rodent and primate models of anxiety.[Pubmed:8545524]
Psychopharmacology (Berl). 1995 Sep;121(2):186-91.
The non-peptide NK2 receptor antagonist, GR159897, was evaluated in two putative models of anxiety, the mouse light-dark box and the marmoset human intruder response test. Effects were compared to the structurally dissimilar NK2 antagonist, (+/-) SR48968 and the benzodiazepines, diazepam and chlordiazepoxide. GR159897 (0.0005-50 micrograms/kg SC) caused significant and dose-dependent increases in the amount of time mice spent in the more aversive light compartment of the light-dark box, with no effect on locomotor activity. (+/-)SR48968 (0.0005-0.5 microgram/kg SC) and diazepam (1-1.75 mg/kg SC), also increased time spent in the light compartment, without effect on locomotor activity. In the marmoset human intruder response test, GR159897 (0.2-50 micrograms/kg SC) significantly increased the amount of time marmosets spent at the front of the cage during confrontation with a human observer ("threat"). Similar effects were produced by (+/-)SR48968 (10-50 micrograms/kg SC) and chlordiazepoxide (0.3-3.0 mg/kg SC). These results provide further evidence, in both rodent and primate species, for the ability of NK2 antagonists to restore behaviours which have been suppressed by novel aversive environments. Such effects indicate that NK2 antagonists may have anxiolytic activity.
