Synthetic Utility of Yeast Hexokinase. Substrate Specificity, Cofactor Regeneration, and Product Isolation

Yeast hexokinase (EC 2.7.1.1) catalyzes the phosphorylation of pyranose and furanose analogs of glucose at 0.01-125% of the rate of glucose. The enzyme is highly tolerant of structural changes at C-2 and C-3 of glucopyranose and less tolerant of changes at C-1 and C-4. Preparative phosphorylations were performed on compounds having 0.01-100% of the activity of glucose, using phosphoenolpyruvate and pyruvate kinase to regenerate ATP. The effects of inhibition of hexokinase by phosphoenolpyruvate and acetyl phosphate on cofactor regeneration are discussed.

Syntheses of Bis-Triazole Linked Carbohydrate Based Macrocycles and Their Applications for Accelerating Copper Sulfate Mediated Click Reaction

Macrocyclic compounds play an important role in many research fields including drug discovery and development, bioorganic chemistry, and materials sciences. Carbohydrate-based macrocycles are important compounds with unique structures and many potential applications. In this study, we have designed and synthesized a series of 1,2,3-triazole linked and pyranose embedded macrocycles in short steps through the copper (I) catalyzed azide and alkyne cycloaddition reactions (CuAACs). Eight non-symmetrical glucosamine based and bis-triazole linked macrocycles have been synthesized starting from the readily available N-acetyl-d-glucosamine. These triazole-linked glycomacrocycles showed remarkable reaction rate accelerations for CuSO4 mediated azide and alkyne cycloaddition reactions in aqueous mixtures. Several azides including a sugar azide, which react sluggishly with alkynes, have been accelerated with the synthesized macrocycles. The benzoylated macrocycles with three methylene linkage at anomeric positions were the most effective among the eight macrocycles.

An Enantio- and Diastereoselective Chemoenzymatic Synthesis of alpha-Fluoro beta-Hydroxy Carboxylic Esters

The trans-o-hydroxybenzylidene pyruvate aldolase-catalysed reactions between fluoropyruvate and many (hetero)aromatic aldehydes yield aldol adducts without subsequent dehydration. Treatment of the reaction products with hydrogen peroxide yields the corresponding syn-configured alpha-fluoro beta-hydroxy carboxylic acids which have >98 % ee. The overall chemoenzymatic approach, in which fluoropyruvate serves as a fluoroacetate equivalent, may be exploited in the synthesis of polar building blocks and fragments with potential value in drug discovery.

Glycosylation of a model proto-RNA nucleobase with non-ribose sugars: Implications for the prebiotic synthesis of nucleosides

The emergence of nucleosides is an important, but poorly understood, element of the origins of life. We show that 2,4,6-triaminopyrimidine (TAP), a possible ancestral nucleobase of RNA, is glycosylated in water by non-ribose sugars in yields comparable to those previously reported for its reaction with ribose. The various sugars surveyed include ketoses and aldoses; tetroses, pentoses, and hexoses and are neutral, anionic, or cationic. Though they vary greatly in structure and properties, the data show that all sugars tested form glycosides with TAP. The structures of the eight TAP glycosides formed with glucose and two of its derivatives, glucose-6-phosphate and N-acetylglucosamine, were found to be beta-pyranosides with the glycosylation site on TAP varying with sugar identity. Our results suggest that prebiotic nucleoside formation would not have been restricted to ribose if ancestral RNA (or proto-RNA) utilized TAP and/or other proto-nucleobases with similar reactivities, and that the ability to form higher-order structures may have influenced proto-RNA monomer selection.

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.

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.
