Asymmetric allylboration of 2-N,3-O-isopropylidene-N-Boc-L-serinal: Diastereoselective synthesis of the calicheamicin gamma1(I) amino sugar

Syntheses of the calicheamicin amino sugar 6 and its erythro diastereomer 7 have been completed by a sequence involving the asymmetric allylboration of N-Boc-serinal acetonide L-8 with the tartrate ester modified allylboronates (R,R)-9 and (S,S)-9, respectively. The reaction of (R,R)-9 and L-8 in toluene provides 14 with 89:11 selectivity, whereas the reaction of (S,S)-9 with L-8 in Et2O provides the diastereomer 15 with 90:10 selectivity. It is shown that the relatively modest diastereoselectivity of these double asymmetric reactions is compromised by the low enantiomeric purity of 8 (86-87% ee), and data are provided indicating that these reactions should be highly diastereoselective (?95:5 in each case) if performed with enantiomerically pure aldehyde. The two diastereomeric homoallylic alcohols, 14 and 15, are easily elaborated into the targeted amino sugars 6 and 7 via the acetamide-substituted pyranosides 22 and 26. Methyl pyranosides 22a and 22e were shown to adopt preferentially the unexpected conformations B and D, with axial acetamide substituents, in nonpolar solvents, while the expected conformations A and C were strongly favored in d6-DMSO because of hydrogen bonding interactions with the solvent. The syntheses of 6 and 7 reported herein are expected to facilitate the design and synthesis of analogs of the calicheamicin aryl tetrasaccharide 3, which should prove useful in further analysis and applications of oligosaccharides as DNA binders.

Regioselective thiolation of arenes and heteroarenes: C-H functionalization strategy for C-S bond formation

A facile transition-metal-free oxidative cross-dehydrogenative coupling reaction involving selective formation of a C-S bond leading to the synthesis of arylthiobenzoxazoles, heteroarylthiobenzoxazoles, and arylthiobenzothiazoles has been described. This highly regioselective C-H functionalization reaction with electron-rich aromatic systems including heteroaromatics is achieved by reversing the reactivity of sulfur in the presence of a suitable oxidant and strong acid.

Effect of bilberry extract (Vaccinium myrtillus L.)on drug-metabolizing enzymes in rats

Vaccinium myrtillus L. (bilberry)fruit is a blue-colored berry with a high content of anthocyanins. These bioactive secondary metabolites are considered to play a major role in the health-promoting properties of bilberries. Our in vivo study was designed to assess the possible influence of bilberry extract on drug-metabolizing enzymes (DMEs). Rats were exposed to bilberry extract in drinking water at two concentrations (0.15 and 1.5 g/L). Selected DMEs were determined (mRNA expression and enzymatic activity)after 29 and 58 days in rat liver. In addition, a panel of antioxidant, physiological, biochemical and hematological parameters was studied; these parameters did not demonstrate any impact of bilberry extract on the health status of rats. A significant increase in activity was observed in cytochrome P450 (CYP)2C11 (131% of control)and CYP2E1 (122% of control)after a 29-day administration, while the consumption of a higher concentration for a longer time led to a mild activity decrease. Slight changes were observed in some other DMEs, but they remained insignificant from a physiological perspective. According to our results, we conclude that the consumption of bilberries as a food supplement should not pose a risk of interacting with co-administered drugs based on their metabolism.

Non-oxidative ethanol metabolism in human hepatic cells in vitro: Involvement of uridine diphospho-glucuronosyltransferase 1A9 in ethylglucuronide production

Ethanol is the most frequently psychoactive substance used in the world, leading to major public health problems with several millions of deaths attributed to alcohol consumption each year. Metabolism of ethanol occurs mainly in the liver via the predominant oxidative metabolism pathway involving phase I enzymes including alcohol dehydrogenases (ADH), cytochrome P450 (CYP) 2E1 and catalase. In a lesser extent, an alternative non-oxidative pathway also contributes to the metabolism of ethanol, which involves the uridine diphospho-glucuronosyltransferase (UGT) and sulfotransferase (SULT) phase II enzymes. Using liquid chromatography-high resolution mass spectrometry, ethylglucuronide (EtG) and ethylsulfate (EtS) produced respectively by UGT and SULT conjugation and detected in various biological samples are direct markers of alcohol consumption. We report herein the efficient non-oxidative metabolic pathway of ethanol in human differentiated HepaRG cells compared to primary human hepatocytes (HH). We showed dose- and time-dependent production of EtS and EtG after ethanol (25 or 50 mM) treatment in culture media of differentiated HepaRG cells and HH and a significant induction of CYP2E1 mRNA expression upon acute ethanol exposure in HepaRG cells. These differentiated hepatoma cells thus represent a suitable in vitro human liver cell model to explore ethanol metabolism and more particularly EtG and EtS production. In addition, using recombinant HepG2 cells expressing different UGT1A genes, we found that UGT1A9 was the major UGT involved in ethanol glucuronidation.

Beneficial pharmacokinetic drug interactions: A tool to improve the bioavailability of poorly permeable drugs

Simultaneous oral intake of herbs, supplements, foods and drugs with other drug(s) may result in pharmacokinetic or pharmacodynamic interactions with the latter. Although these interactions are often associated with unwanted effects such as adverse events or inefficacy, they can also produce effects that are potentially beneficial to the patient. Beneficial pharmacokinetic interactions include the improvement of the bioavailability of a drug (i.e., by enhancing absorption and/or inhibiting metabolism) or prolongation of a drug?s plasma level within its therapeutic window (i.e., by decreasing excretion), whereas beneficial pharmacodynamic interactions include additive or synergistic effects. Mechanisms by which pharmacokinetic interactions can cause beneficial effects include enhancement of membrane permeation (e.g., structural changes in the epithelial cell membranes or opening of tight junctions), modulation of carrier proteins (e.g., inhibition of efflux transporters and stimulation of uptake transporters) and inhibition of metabolic enzymes. In the current review, selected pharmacokinetic interactions between drugs and various compounds from different sources including food, herb, dietary supplements and selected drugs are discussed. These interactions may be exploited in the future to the benefit of the patient, for example, by delivering drugs that are poorly bioavailable in therapeutic levels via alternative routes of administration than parenteral injection.

Synthesis of benz[d]oxazolones involving concomitant acetyl migration from oxygen to nitrogen

Heating of o-acetoxybenzoyl azides 6-10 in toluene leads to the Curtius reaction, which, when followed by closure of oxazolone ring with concomitant migration of acetyl group from oxygen to nitrogen, produces 3-acetoxybenz[d] oxazol-2(3H)-ones 11-15, which undergo hydrolysis with hot dilute hydrochloric acid to furnish benz[d]oxazol-2(3H)-ones 17-21.

3-[1-(2-Benzoxazolyl)hydrazino]propanenitrile derivatives: Inhibitors of immune complex induced inflammation

3-[1-(2-Benzoxazolyl)hydrazino]propanenitrile derivatives were evaluated in the dermal and pleural reverse passive Arthus reactions in the rat. In the pleural test these compounds were effective in reducing exudate volume and accumulation of white blood cells. This pattern of activity was similar to that of hydrocortisone and different from that of indomethacin. The structural requirements for inhibiting the Arthus reactions were studied by systematic chemical modification of 1. These structure-activity relationship studies revealed that nitrogen 1′ of the hydrazino group is essential for activity and must be electron rich, whereas chemical modifications of other sites of 1 had only a modest effect on activity.
