Reference of 499-40-1. Let’s face it, organic chemistry can seem difficult to learn. Especially from a beginner’s point of view. Like 499-40-1, Name is (2R,3S,4R,5R)-2,3,4,5-Tetrahydroxy-6-(((2S,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)hexanal. In a document type is Article, introducing its new discovery.

Solid and solution structures of ternary gold(I) complexes with triphenylphosphine and nitrogen-containing ligands

A series of gold(I) complexes [Au(PPh3)L]ClO4 (L = pyridine 1a, 2,6-dimethylpyridine 1b, 2,6-di-tert-butylpyridine 1c, quinoline 1d, acridine 1e, benzo[h]quinoline 1f, naphthyridine 2a, 1,10-phenanthroline 2b, 2,2?-biquinoline 2c, di-2-pyridyl ketone 2d, di-2-pyridylamine 3a or 2-(2-pyridyl)benzimidazole 3b) were prepared by reaction of L with [Au(PPh3)(ClO4)] which was synthesized in situ. All complexes were characterized by IR, UV/VIS and 1H NMR spectroscopy. The crystal and molecular structures of 1b, 2a and 3b were investigated by single-crystal X-ray diffraction techniques. The gold(I) is co-ordinated to one nitrogen atom and one phosphine atom. Detailed 1H NMR studies suggested that linear two-co-ordinated structures persist in solution and further that all the complexes [Au(PPh3)L]ClO4, (2a-2d), are fluxional species in which the co-ordination site of gold(I) rapidly exchanges between two nitrogen atoms of the ligand.

3-[(1 S,2 S,3 R)-2,3-Difluoro-1-hydroxy-7-methylsulfonylindan-4-yl]oxy-5-fluorobenzonitrile (PT2977), a Hypoxia-Inducible Factor 2alpha (HIF-2alpha) Inhibitor for the Treatment of Clear Cell Renal Cell Carcinoma

The hypoxia-inducible factor 2alpha (HIF-2alpha) is a key oncogenic driver in clear cell renal cell carcinoma (ccRCC). Our first HIF-2alpha inhibitor PT2385 demonstrated promising proof of concept clinical activity in heavily pretreated advanced ccRCC patients. However, PT2385 was restricted by variable and dose-limited pharmacokinetics resulting from extensive metabolism of PT2385 to its glucuronide metabolite. Herein we describe the discovery of second-generation HIF-2alpha inhibitor PT2977 with increased potency and improved pharmacokinetic profile achieved by reduction of phase 2 metabolism. Structural modification by changing the geminal difluoro group in PT2385 to a vicinal difluoro group resulted in enhanced potency, decreased lipophilicity, and significantly improved pharmacokinetic properties. In a phase 1 dose-escalation study, the clinical pharmacokinetics for PT2977 supports the hypothesis that attenuating the rate of glucuronidation would improve exposure and reduce variability in patients. Early evidence of clinical activity shows promise for PT2977 in the treatment of ccRCC.

Metal-metal versus metal-ligand bonding in dimetal compounds with tridentate ligands

Reaction of a ‘VCl2·nTHF’ solution, prepared by the reduction of VCl3(THF)3 with NaBEt3H in THF, and Lidpa (dpa = the anion of 2,2′-dipyridylamine) in a mixture of THF/toluene at reflux temperature yields the bioctahedral V2(dpa)4·THF (1) compound. A similar reaction performed in THF at 0C gave [V2(dpa)3(mu-Cl)2Li2(THF)6][BEt3H] (2), in which a dpa ligand adopts a novel ‘doubly-chelating/bridging’ coordination mode. Compound 2 reacts with CH2Cl2 giving V2(dpa)3Cl2·2CH2Cl2 (3), a valence delocalized V(II)···V(6III) bioctahedral complex. In all three complexes, the formation of four additional metal-ligand bonds is favored over the formation of a V-V bond. The V···V separations are 3.038(2), 3.024(2) and 3.091(2) A? for 1-3, respectively. Crystal data are: compound 1, space group P2/n a = 13.102(2), b = 9.294(2), c = 16.510(4) A?, beta = 98.98(2), V = 1985.7(6) A?3 and Z = 2; compound 2, space group I2/a, a = 19.4674(8), b = 14.390(1), c = 24.219(2) A?, beta = 92.954(7), V = 6775.4(7) A?3 and Z = 2; compound 3, space group P21/c, a = 12.0853(8), b = 18.679(2), c = 16.709(2), beta = 109.98(1), V = 3544.9(6) A?3 and Z = 4.

Hydrothermal synthesis, crystal structures and effect of non bonding interactions in crystal packing of two mixed-ligand metal complexes with glycolato and 2,2?-dipiridylamine and with benzilato and imidazole

Two new mixed-ligand complexes [Fe(HG)2(dipyam)] (1) (HG = glycolato and dipyam = 2,2?-dipyridylamine) and [Cu(HB) 2(im)2]·2H2O (2) (HB = benzilato and im = imidazole) have been hydrothermally synthesized and structurally characterised by X-ray diffraction. In both cases the metallic centre is in an octahedral environment, strongly distorted in 2 (4+2 coordination). The alpha-hydroxycarboxylato ligands (glycolato or benzilato) present different coordinative behaviour, bidentade chelate through the hydroxyl oxygen and one carboxy oxygen in 1 and through the two oxygen atoms of the carboxylate group in 2. The complexes are extended into 2D frameworks through hydrogen bonding and pi…pi or C-H…pi interactions. The complexes were also characterized by elemental analysis, FT-IR and UV-vis spectroscopy and room temperature magnetic measurements.
