Discovery and Optimization of Allosteric Inhibitors of Mutant Isocitrate Dehydrogenase 1 (R132H IDH1) Displaying Activity in Human Acute Myeloid Leukemia Cells

A collaborative high throughput screen of 1.35 million compounds against mutant (R132H) isocitrate dehydrogenase IDH1 led to the identification of a novel series of inhibitors. Elucidation of the bound ligand crystal structure showed that the inhibitors exhibited a novel binding mode in a previously identified allosteric site of IDH1 (R132H). This information guided the optimization of the series yielding submicromolar enzyme inhibitors with promising cellular activity. Encouragingly, one compound from this series was found to induce myeloid differentiation in primary human IDH1 R132H AML cells in vitro.

Network single ion conductors based on comb-branched polyepoxide ethers and lithium bis(allylmalonato)borate

The synthesis of network single ion conductors to obtain single ion conductors with high ambient temperature conductivity and mechanical strength is discussed. The single ion conductors were based on comb-branched polyepoxide ethers and lithium (Li) bis(allylmelonato)borate. The single ion conductors possessed good mechanical strength due to the formation of network structure and the Li/Li symmetric cell cycling showed no concentration polymerization. The results show that the backbone structure of the polyepoxides contributes to the total ionic conductivity and it increases with the increasing side chain length.

Effect of ABCB1 polymorphisms and atorvastatin on sitagliptin pharmacokinetics in healthy volunteers

Objectives: The objectives of this study were to determine if ABCB1 polymorphisms are associated with interindividual variability in sitagliptin pharmacokinetics and if atorvastatin alters the pharmacokinetic disposition of sitagliptin in healthy volunteers. Methods: In this open-label, randomized, two-phase crossover study, healthy volunteers were prospectively stratified according to ABCB1 1236/2677/3435 diplotype (n = 9, CGC/CGC; n = 10, CGC/TTT; n = 10, TTT/TTT). In one phase, participants received a single 100 mg dose of sitagliptin; in the other phase, participants received 40 mg of atorvastatin for 5 days, with a single 100 mg dose of sitagliptin administered on day 5. A 24-h pharmacokinetic study followed each sitagliptin dose, and the study phases were separated by a 14-day washout period. Results: Sitagliptin pharmacokinetic parameters did not differ significantly between ABCB1 CGC/CGC, CGC/TTT, and TTT/TTT diplotype groups during the monotherapy phase. Atorvastatin administration did not significantly affect sitagliptin pharmacokinetics, with geometric mean ratios (90 % confidence intervals) for sitagliptin maximum plasma concentration, plasma concentration-time curve from zero to infinity, renal clearance, and fraction of sitagliptin excreted unchanged in the urine of 0.93 (0.86-1.01), 0.96 (0.91-1.01), 1.02 (0.93-1.12), and 0.98 (0.90-1.06), respectively. Conclusions: ABCB1 CGC/CGC, CGC/TTT, and TTT/TTT diplotypes did not influence sitagliptin pharmacokinetics in healthy volunteers. Furthermore, atorvastatin had no effect on the pharmacokinetics of sitagliptin in the setting of ABCB1 CGC/CGC, CGC/TTT, and TTT/TTT diplotypes.

60. Derives de desoxy-hydroxylamino-sucres et radicaux libres diglycosylnitroxydes correspondants

A number of sugar aldonitrones, including C,N-diglycosylnitrones, and ketonitrones have been treated with Grignard reagents or cyanide anion leading to the corresponding deoxy-hydroxylamino-sugars.On oxidation (air, H5IO6 or PbO2), these compounds gave the corresponding nitroxide radicals whose ESR. spectra are reported.Analogues of disaccharides, in which the interglycosidic O-bridge is replaced by a hydroxyimino group, have been obtained by reacting a partially blocked sugar bearing a free hemiacetal group either with a deoxy-hydroxylamino-sugar or with hydroxylamine, followed by reaction with an aldehydosugar and a reducing agent (NaBH4).These reactions represents the key synthetic steps for the oligosaccharide-type synthesis of deoxy-hydroxyimino-oligosaccharides.Their oxidation yielded the corresponding nitroxide radicals whose ESR. spectra gave information on the conformation about the ‘interglycosidic’ bridge.This type of compounds should constitute useful spin markers for biological studies.

Synthesis of the monosaccharide units of the O-specific polysaccharide of Shigella sonnei

The monosaccharide components of the O-specific polysaccharide 1 of the lipopolysaccharide of the enteropathogenic bacterium Shigella sonnei were synthesized as their methyl glycosides 2 and 3 in their natural anomeric form. The key intermediate to the diaminotrideoxygalactose derivative 2 was ethyl-3-O-acetyl-2-deoxy-2-phthalimido-1-thio-beta-D- glucopyranoside (9) that was converted to its ditosylate 10. Regioselective deoxygenation at C-6 followed by nucleophilic displacement of the secondary tosyloxy group by azide afforded the 4-azido thioglycoside 13. Methyl trifluoromethanesulfonate-assisted methanolysis of 13 gave the O-glycoside 14. Replacement of the phthalimido by an acetamido group followed by catalytic reduction of the azido group led to the diamino-trideoxygalactose derivative 2. The precursor to the L-altruronic acid derivative 3 was methyl alpha-L-glucopyranoside (19) that was routinely converted to the benzylidene-protected 2,3-anhydro-allopyranoside 22. Regioselective opening of the epoxide ring by NaN3 afforded the 2-azido derivative 23 that was benzylated at HO-3. Hydrolytic removal of the benzylidene group followed by TEMPO oxidation of C-6 and subsequent esterification with MeI gave the key L-azido-altruronic acid intermediate 29 that was transformed to the acetamido-altruronic acid derivative 3. High resolution NMR data of the altruronic acid derivatives indicate that the conformation of their pyranose ring is crucially dependent on the substitution pattern: the 2-azido altruronic acid derivatives prefer the 4C1 conformation whereas the 2-acetamido congeners exist preferentially in the 1C4 conformation.

Synthesis and biological activity of naphthalene analogues of phenstatins: Naphthylphenstatins

Novel phenstatin analogues with a 2-naphthyl moiety combined with either a 2,3,4- or a 3,4,5-trimethoxyphenyl ring have been synthesized, and their tubulin polymerization inhibiting and cytotoxic activities have been evaluated. The 2-naphthyl ring is a better replacement for the 3-hydroxy-4-methoxyphenyl ring in the phenstatin series than in the combretastatin series. For the naphthylphenstatins, the carbonyl is required, and the preferred orientation of the trimethoxyphenyl ring is the one found in combretastatins.

Tetrahydroquinoline derivatives as opioid receptor antagonists

Opioid receptors play an important role in both behavioral and homeostatic functions. We herein report tetrahydroquinoline derivatives as opioid receptor antagonists. SAR studies led to the identification of the potent antagonist 2v, endowed with 1.58 nM (Ki) functional activity against the mu opioid receptor. DMPK data suggest that novel tetrahydroquinoline analogs may be advantageous in peripheral applications.

Electron Delocalization of Mixed-Valence Diiron Sites Mediated by Group 10 Metal Ions in Heterotrimetallic Fe-M-Fe (M=Ni, Pd, and Pt) Chain Complexes

The heterotrimetallic complexes [FeMFe(dpa)4Cl2] (M=Ni (1), Pd (2), and Pt (3); dpa?=dipyridylamido) featuring two high-spin iron centers linked by Group 10 metals were synthesized and their physical properties were investigated. Oxidation of 1?3 with suitable oxidants in CH2Cl2 solution yielded the mixed-valent species [1]+/2+?[3]+/2+. The solution properties of [1]0/+/2+?[3]0/+/2+ were characterized by 1H NMR and UV/Vis/NIR spectroscopy as well as spectroelectrochemisty. The mixed-valent states of [1]+?[3]+ obtained by electrochemical or chemical oxidation are classified as class II valence delocalization. The solid-state structures of 1?3, [1]+, [3]+, and [1]2+ were determined by single-crystal X-ray diffraction analysis, exhibiting a linear metal framework with an approximate D4 symmetry. The spin states and magnetic properties were studied by using SQUID magnetometry, EPR and Moessbauer spectroscopy, and DFT calculations. Antiferromagnetic interactions between terminal high-spin iron centers are present within [1]0/+/2+?[3]0/+/2+ and the |J| values increase with the central metal ion changing from Ni to Pt. The DFT calculations reproduce the antiferromagnetic coupling and ascribe it to a sigma-type exchange pathway. The substitution of the central metal not only influences the spin?spin interactions but also the degree of electronic delocalization between the terminal iron sites along the Fe-M-Fe chains.
