Asymmetric synthesis of the allocolchicinoid natural product N-acetylcolchinol methyl ether (suhailamine), solid state and solution phase conformational analysis

An asymmetric synthesis of the allocolchicinoid N-acetylcolchinol methyl ether (NCME) from 3-methoxybenzaldehyde is reported. Comparison of H-1 and C-13 NMR spectroscopic data obtained for this sample of NCME provide further evidence for the assertion that this compound is congruous with the natural product that has been dubbed suhailamine, establishing NCME as a naturally-occurring allocolchicinoid. The single crystal X-ray diffraction structure of NCME is also reported for the first time, revealing a preference for adoption of the (7S,R-a,Z) form-i.e., describing the orientation of the biaryl axis and the amide N-CO bond as well as the configuration of the stereocenic centre-in the solid state. A preference for the same form in DMSO-d(6) solution is revealed upon analysis by a range of NMR spectroscopic techniques, whilst an interconverting 69:24:7 mixture of the (7S,R-a,Z), (7S,S-a,Z) and (7S,R-a,E) forms is observed in CDCI3.

Thermodynamics of amide plus amine mixtures. 5. Excess molar enthalpies of N,N-dimethylformamide or N,N-dimethylacetamide plus N-propylpropan-1-amine, + N-butylbutan-1-amine, + butan-1-amine, or + hexan-1-amine systems at 298.15 K. Application of the ERAS model

Excess molar enthalpies, H-m(E) , over the whole composition range have been determined for the liquid mixtures N,N-dimethylformamide (DMF) or N,N-dimethylacetamide (DMA) + butan-1-amine (BA), or + hexan-1-amine (HxA), or + N-propylpropan-1-amine (DPA), or N-butylbutan-1-amine (DBA) at 298.15 K and at 0.1 MPa using a BT2.15 calorimeter from Setaram adapted to work in dynamic mode at constant temperature and pressure. All the H-m(E) values are positive, indicating that interactions between like molecules are predominant. The replacement of DMF by DMA in systems with a given amine leads to lower H-m(E) results, which have been ascribed to stronger amide-amide interactions in DMF mixtures. The replacement of HxA by DPA in systems with a given amide leads to slightly higher 4 values, as interactions between unlike molecules are weaker for the latter. Structural effects in the investigated solutions are also present, since the corresponding excess molar volumes (V-m(E)), previously determined, are negative or slightly positive. The systems have been characterized in terms of the ERAS model reporting the interaction parameters. The model correctly describes both H-m(E) and V-m(E) The application of the model suggests that, in the systems under study, solvation effects are of minor importance and that physical interactions are dominant.

Connector Type-Controlled Mesophase Structures in Poly(propyl ether imine) Dendritic Liquid Crystals of Identical Dendrimer Generations

Poly(propyl ether imine) (PETIM) dendrimers of one to three generations are used as dendritic cores to identify the influence of varying connector types that connect the dendritic core with peripheral mesogens on the emerging liquid crystalline (LC) properties. The LC properties vary in these dendritic liquid crystals, even when the dendrimer generations and thus the number of peripheral mesogenic moieties remain identical. PETIM dendrimer generations one to three, ester and amide connectors varying with succinates, phthalates, and succinamides, are studied herein. Cholesteryl moieties are installed at the peripheries through the above connectors to induce mesogenic properties. These modified dendritic liquid crystals reveal a layered mesophase structure in most ester and amide connector-derivatives, whereas a third-generation phthalate ester dendrimer favors a rectangular columnar mesophase structure. A transition from layered to a rectangular columnar structure results by a mere change in the connector varying between a succinate or succinamide or phthalate, within one particular dendrimer generation and without altering the underlying dendrimer core or the number of mesogenic moieties. The study demonstrates that in dendritic liquid crystals with essentially identical chemical constitutions, a change in the connector type connecting the mesogen with the dendrimer core is sufficient to change the mesophase structures.

Chemoenzymatic Posttranslational Modification Reactions for the Synthesis of psi[CH2NH]-Containing Peptides

The psi[CH2NH] reduced amide bond is a peptide isostere widely used in the development of bioactive pseudopeptides. Reported here is a method of chemoenzymatic posttranslational modification for the synthesis of psi[CH2NH]-containing peptides converted from ribosomally expressed peptides. The posttranslational conversion composed of an enzymatic cyclodehydration and facile two-step chemical reduction achieves deoxygenation of a specific amide bond present in a nonprotected peptide in water. This method generates the psi[CH2NH] bond in peptides and is applicable to various peptide sequences, potentially enabling the preparation of a library of psi[CH2NH]-containing peptides.

1,8-Bis(borylamido)naphthalene Complexes of Lithium and Zinc(II) Including a Zinc(II) Isocyanide Adduct

The zinc coordination chemistry of a useful metal ion chelator, bis(borylamido)naphthalene ligand [1,8-C10H6(NBNL)(2)](2-), which has two borylamido groups on a rigid naphthalene backbone, is presented. Deprotonation of N-1,N-8-di(9-bora-bicyclo[3.3.1]nonan-9-yl)naphthalene-1,8-diamine, [1,8-C10H6(NBNL)(2)]H-2 (3) with two equivalents of nBuLi in Et2O afforded the lithium derivative, Li-2(Et2O)(2)[1,8-C10H6(NBNL)(2)] (4). Metathesis reaction of Li-2(Et2O)(2)[1,8-C10H6(NBNL)(2)] with (tBu(2)bipy)ZnCl2 (tBu(2)bipy = 4,4-di-tert-butyl-2,2-bipyridine) in a 1:1 molar ratio gave [1,8-C10H6(NBNL)(2)]Zn(tBu(2)bipy) (5), which features an all-nitrogen coordination sphere at zinc. The reaction of 4 with ZnCl2, however, produced [1,8-C10H6(NBNL)(2)]Zn(Et2O)(mu-Cl)Li(Et2O)(3) (6), which retains one of the chlorides as ClLi(Et2O)(3) on zinc. Treatment of 6 with tBu(2)bipy or two equivalents of 2,6-dimethylphenyl isocyanide completes the salt elimination and led to [1,8-C10H6(NBNL)(2)]Zn(tBu(2)bipy) (5) or [1,8-C10H6(NBNL)(2)]Zn(CNC6H3-2,6-Me-2)(2) (7), respectively. Compounds 3-7 have been characterized by several analytical methods including X-ray crystallography. The zinc atoms of 5-7 are four-coordinate and adopt a distorted tetrahedral geometry. The (NC) bands of 7 in the IR spectrum have been observed at 2203 and 2187 cm(-1).

In vitro multiplication, genetic fidelity and phytochemical potentials of Vaccinium arctostaphylos L.: An endangered medicinal plant

Caucasian whortleberry (Vaccinium arctostaphylos L.) plant traditionally has been included among important medicines as remedy for diabetic patients and also in modem medicine found to be effective against cardiovascular diseases. V. arctostaphylos leaves are known to be rich in phytochemicals, however, no comprehensive and reliable protocol has been developed to date in order to produce plant materials for conservation purposes and/or to generate secondary metabolites under in vitro conditions. Therefore, present study was designed to develop a micropropagation system having high genetic fidelity and considerable potential to produce secondary chemicals from V. arctostaphylos. No morphological dissimilarities have been observed in tissue culture-produced shoots after their successfully placement in a greenhouse with high survival rate (>= 90%). At the end of 2nd subculture, woody plant medium (WPM) containing moderate level of plant growth regulators (PGRs) such as Zeatin (2 ppm) and Auxin (Indole-3-butyric acid – IBA; 0.1 ppm) has significantly increased shoot length and shoot numbers per explants, whereas, other vegetative growth characteristics have shown significant increase in mediums containing the highest Zeatin and IBA concentrations. Half-strength WPM medium containing IBA (1 ppm) and activated charcoal (AC; 0.2%) showed maximum root length, number of roots and rooted explants and that the increasing concentrations of IBA and AC have positively improved root induction. Genetic homogeneity of the micropropagated plants has been analyzed using four pairs of simple sequence repeats (SSR) markers. Proliferated plants showed monomorphic bands identical to the donor plant and manifested the genetic stability of the newly produced plants. Different assays were used to measure the antioxidant potential and phenolic compound from in vitro, acclimatized and mother plant leaves. In all experiments, PGRs esp., Zeatin has shown significant effects on antioxidant scavenging, phenolic and flavonoid content of micropropagated plants. Metabolite screening using Infrared Spectroscopy (IR) indicated the presence of various functional groups such as amines, amides, carboxylic acids, esters, alkanes and aliphatic amine similar to mother plants. Results from present study have clearly indicated that the acclimatized plants of V. arctostaphylos could have been a reliable source for in vitro or ex-situ conservation and breeding program and, therefore, its conservation may highly be important due to availability of medicinally valuable plant secondary metabolites.

Lanthanide-Based T-2ex and CEST Complexes Provide Insights into the Design of pH Sensitive MRI Agents

The CEST and T-1/T-2 relaxation properties of a series of Eu3+ and Dy3+ DOTA-tetraamide complexes with four appended primary amine groups are measured as a function of pH. The CEST signals in the Eu3+ complexes show a strong CEST signal after the pH was reduced from 8 to 5. The opposite trend was observed for the Dy3+ complexes where the r(2ex) of bulk water protons increased dramatically from ca. 1.5 mM(-1) s(-1) to 13 mM(-1) s(-1) between pH 5 and 9 while r(1) remained unchanged. A fit of the CEST data (Eu3+ complexes) to Bloch theory and the T-2ex data (Dy3+ complexes) to Swift-Connick theory provided the proton-exchange rates as a function of pH. These data showed that the four amine groups contribute significantly to proton-catalyzed exchange of the Ln(3+)-bound water protons even though their pK(a)’s are much higher than the observed CEST or T-2ex effects. This demonstrated the utility of using appended acidic/basic groups to catalyze prototropic exchange for imaging tissue pH by MRI.

Piperidine and piperazine inhibitors of fatty acid amide hydrolase targeting excitotoxic pathology

FAAH inhibitors offer safety advantages by augmenting the anandamide levels on demand to promote neuroprotective mechanisms without the adverse psychotropic effects usually seen with direct and chronic activation of the CB1 receptor. FAAH is an enzyme implicated in the hydrolysis of the endocannabinoid N-arachidonoylethanolamine (AEA), which is a partial agonist of the CB1 receptor. Herein, we report the discovery of a new series of highly potent and selective carbamate FAAH inhibitors and their evaluation for neuroprotection. The new inhibitors showed potent nanomolar inhibitory activity against human recombinant and purified rat FAAH, were selective (> 1000-fold) against serine hydrolases MGL and ABHD6 and lacked any affinity for the cannabinoid receptors CB1 and CB2. Evaluation of FAAH inhibitors 9 and 31 using the in vitro competitive activity-based protein profiling (ABPP) assay confirmed that both inhibitors were highly selective for FAAH in the brain, since none of the other FP-reactive serine hydrolases in this tissue were inhibited by these agents. Our design strategy followed a traditional SAR approach and was supported by molecular modeling studies based on known FAAH cocrystal structures. To rationally design new molecules that are irreversibly bound to FAAH, we have constructed precovalent FAAH-ligand complexes to identify good binding geometries of the ligands within the binding pocket of FAAH and then calculated covalent docking poses to select compounds for synthesis. FAAH inhibitors 9 and 31 were evaluated for neuroprotection in rat hippocampal slice cultures. In the brain tissue, both inhibitors displayed protection against synaptic deterioration produced by kainic acid-induced excitotoxicity. Thus, the resultant compounds produced through rational design are providing early leads for developing therapeutics against seizure-related damage associated with a variety of disorders.

Visible-light-induced direct construction of amide bond from carboxylic acids with amines in aqueous solution

A novel visible-light-promoted N-acylation for the synthesis of amides from easily available carboxylic acids with amines in the presence of I-2 within 2.5 h in aqueous solution has been developed. Using sunlight as the visible light source greatly reduces the cost of experiments and produces almost no toxic effects. Hence, this study provides an alternative catalytic system for the construction of a wide range of amides with readily available materials. Moreover, the strategy was successfully applied in the preparation of N-(3-(2,6-dimethoxyphenoxy)-7-nitroquinoxalin-2-yl)benzohydrazide, which displayed a signification anti-proliferation effect on A549, MCF-7 and HCT116 cell lines.
