Abstract
A rhodium(III)-catalyzed redox-neutral spiroannulation approach to access the spiro[benzo[b][1,4]oxazine-benzo[c]chromene skeleton is described in this contribution. A variety of spiro[5.5]-heterocyclic scaffolds were obtained in moderate to excellent yields under mild conditions. Key features of this protocol are good substrate scope, silver-free conditions, low catalyst loadings, easy handling under air and 100% atom economy. Furthermore, scale-up reactions and late-stage derivatizations highlight the potential synthetic utility of this methodology.

Aquatide Activation of SIRT1 Reduces Cellular Senescence through a SIRT1-FOXO1-Autophagy Axis. Biomol Ther (Seoul) 2017; 25:511-518.

Abstract
Ultraviolet (UV) irradiation is a relevant environment factor to induce cellular senescence and photoaging. Both autophagy- and silent information regulator T1 (SIRT1)-dependent pathways are critical cellular processes of not only maintaining normal cellular functions, but also protecting cellular senescence in skin exposed to UV irradiation. In the present studies, we investigated whether modulation of autophagy induction using a novel synthetic SIRT1 activator, heptasodium hexacarboxymethyl dipeptide-12 (named as Aquatide), suppresses the UVB irradiation-induced skin aging. Treatment with Aquatide directly activates SIRT1 and stimulates autophagy induction in cultured human dermal fibroblasts. Next, we found that Aquatide-mediated activation of SIRT1 increases autophagy induction via deacetylation of forkhead box class O (FOXO) 1. Finally, UVB irradiation-induced cellular senescence measured by SA-β-gal staining was significantly decreased in cells treated with Aquatide in parallel to occurring SIRT1 activation-dependent autophagy. Together, Aquatide modulates autophagy through SIRT1 activation, contributing to suppression of skin aging caused by UV irradiation.

Notoginsenoside Ft1 activates both glucocorticoid and estrogen receptors to induce endothelium-dependent, nitric oxide-mediated relaxations in rat mesenteric arteries. Biochem Pharmacol 2014; 88:66-74. [PMID: 24440742 DOI: 10.1016/j.bcp.2014.01.007] [Citation(s) in RCA: 27] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2013] [Revised: 01/04/2014] [Accepted: 01/07/2014] [Indexed: 01/01/2023]
Abstract
Panax notoginseng (Burk.) F.H. Chen has been used traditionally for the treatment of cardiovascular diseases. Notoginsenoside Ft1 (Ft1) is a bioactive saponin from the leaves of P. notoginseng. Experiments were designed to determine whether or not Ft1 is an endothelium-dependent vasodilator. Rat mesenteric arteries were suspended in organ chambers for the measurement of isometric tension during phenylephrine-induced contractions. The cyclic guanosine monophosphate (cGMP) level was assessed using enzyme immunoassay. The phosphorylation and protein expressions of endothelial nitric oxide synthase (eNOS), glucocorticoid receptors (GR), estrogen receptors beta (ERß), protein kinase B (Akt) and extracellular signal-regulated kinase 1/2 (ERK1/2) were determined by Western blotting. The localization of GR and ERß were determined by immunofluorescence staining. Ft1 caused endothelium-dependent relaxations, which were abolished by l-NAME (inhibitor of nitric oxide synthases) and ODQ (inhibitor of soluble guanylyl cyclase). Ft1 increased the cGMP level in rat mesenteric arteries. GR and ERß were present in the endothelial layer and their antagonism by RU486 and PHTPP, respectively, inhibited Ft1-induced endothelium-dependent relaxations and phosphorylations of eNOS, Akt and ERK1/2. Inhibition of phosphoinositide-3-kinase (PI3K) by wortmannin and ERK1/2 by U0126 reduced Ft1-evoked relaxations and eNOS phosphorylation. Taken in conjunction, the present findings suggest that Ft1 stimulates endothelial GRs and ERßs with subsequent activation of the PI3K/Akt and ERK1/2 pathways in rat mesenteric arteries. This results in phosphorylation of eNOS and the release of NO, which activates soluble guanylyl cyclase in the vascular smooth muscle cells leading to relaxations.

Abstract
Novobiocin, a known DNA gyrase inhibitor, binds to a nucleotide-binding site located on the Hsp90 C-terminus and induces degradation of Hsp90-dependent client proteins at approximately 700 microM in breast cancer cells (SKBr3). Although many analogues of novobiocin have been synthesized, it was only recently demonstrated that monomeric species exhibit antiproliferative activity against various cancer cell lines. To further refine the essential elements of the coumarin core, a series of modified coumarin derivatives was synthesized and evaluated to elucidate structure-activity relationships for novobiocin as an anticancer agent. Results obtained from these studies have produced novobiocin analogues that manifest low micromolar activity against several cancer cell lines.

Abstract
Glucocorticoids control immune homeostasis and regulate stress responses in the human body to a large extent via the glucocorticoid receptor. This transcription factor can modulate gene expression either through direct DNA binding (mainly resulting in transactivation) or independent of DNA binding (in the majority of cases resulting in transrepression). The aim of this review is to discuss the mechanistic basis and applicability of different glucocorticoid receptor modulators in various affections, ranging from immune disorders to mental dysfunctions.

Abstract
The 2-azadecalin ring system was evaluated as a scaffold for the preparation of glucocorticoid receptor (GR) antagonists. High affinity, selective GR antagonists were discovered based on a hypothetical binding mode related to the steroidal GR antagonist RU-43044. 2-Benzenesulfonyl substituted 8a-benzyl-hexahydro-2H-isoquinolin-6-ones exemplified by (R)-37 had low nanomolar affinity for GR with moderate functional activity (200 nM) in a reporter gene assay. These compounds were devoid of affinity for other steroidal receptors (ER, AR, MR, and PR). Analogues based on an alternative putative binding mode (CP-like) were found to be inactive.

Abstract
The radiosynthesis and the radiopharmacological characterization of [(11)C]AL-438 as a nonsteroidal ligand for the glucocorticoid receptor (GR) is described. Radiolabeling of the corresponding desmethyl precursor 10 with [(11)C]MeI gave [(11)C]AL-438 in decay-corrected radiochemical yields of 30+/-4% (based upon [(11)C]CO(2)) within 35 min at a specific radioactivity of 10-15 GBq/micromol at the end-of-synthesis. The radiopharmacological evaluation of [(11)C]AL-438 involved biodistribution and small animal PET imaging in rats, and autoradiography studies using rat brain sections. Biodistribution studies were performed in male Wistar rats and demonstrated high radioactivity uptake in pituitary and brain. However, the inability of high dose corticosterone to block binding would suggest that the radioactivity accumulation in the brain was not receptor-mediated.

Abstract
A novel and non-ODS-based (ODS = ozone-depleting substance) preparation of 2-chloro-2,2-difluoroacetophenone (1) was achieved in high yield by using 2,2,2-trifluoroacetophenone as the starting material. Compound 1 was found to act as a good difluorocarbene reagent, which readily reacts with a variety of structurally diverse phenol derivatives 4 in the presence of potassium hydroxide or potassium carbonate to produce aryl difluoromethyl ethers 5 in good yields. This new and easy-to-handle synthetic methodology offers an environmentally friendly alternative to other Freon- or Halon-based difluoromethylating approaches.
