The performances of the M06-2X and omega B97X-D functionals with various basis sets as well as the double-hybrid DSD-PBEP86-D3BJ/cc-pVTZ level of theory with the implicit PCM and SMD solvation methods were assessed for the conformational preferences of Ac-Pro-NHMe in chloroform and water. The M06-2X/def2-TZVP//M06-2X/6-31+G(d) and DSD-PBEP86-D3BJ/cc-pVTZ//M06-2X/6-31+G(d) methods with PCM in chloroform and SMD in water exhibited the best performances for these conformational preferences consistent with experimental results in chloroform and water. As a further step in checking the applicability of these DFT methods, we have undertaken a study of the conformational preferences of Ac-Pro-OMe, Ac-X-OMe, and Ac-X-NHMe (X = Pro derivatives) in chloroform and/or water. Almost the same results were obtained at both levels of theory. The order of the distributions of puckerings depending on the trans and cis peptide bonds was different depending on the substitution position, the chirality, and the solvent polarity. The cis populations of the prolyl peptide bond for Ac-X-OMe and Ac-X-NHMe (X = Pro and its derivatives) were well predicted with RMSD < 6% in chloroform and water, compared with the experimental values. In addition, the calculated barriers Delta G(c-t)double dagger to the cis-to-trans isomerization of the prolyl peptide bond for Ac-Pro-NHMe, Ac-X-OMe (X = Pro, Hyp, Flp, and flp), and Ac-X-NHMe (X = 5-Mep, 5-Tbp, and 5-tbp) in chloroform and/or water were consistent with the experimental values within 1 kcal mol(-1). Hence, the M06-2X/def2-TZVP//M06-2X/6-31+G(d) and DSD-PBEP86-D3BJ/cc-pVTZ//M06-2X/6-31+G(d) methods with PCM in chloroform and SMD in water appeared to be appropriate in predicting the conformational preferences and the cis-trans isomerization of the longer peptides containing Pro or Pro derivatives in chloroform and water.

SpyTag is a peptide that forms a spontaneous amide bond with its protein partner SpyCatcher. This protein superglue is a broadly useful tool for molecular assembly, locking together biological building blocks efficiently and irreversibly in diverse architectures. We initially developed SpyTag and SpyCatcher by rational design, through splitting a domain from a Gram-positive bacterial adhesin. In this work, we established a phage-display platform to select for specific amidation, leading to an order of magnitude acceleration for interaction of the SpyTag002 variant with the SpyCatcher002 variant. We show that the 002 pair bonds rapidly under a wide range of conditions and at either protein terminus. SpyCatcher002 was fused to an intimin derived from enterohemorrhagic Escherichia coli. SpyTag002 reaction enabled specific and covalent decoration of intimin for live cell fluorescent imaging of the dynamics of the bacterial outer membrane as cells divide.

The removal of ester and amide groups is of fundamental significance in organic syntheses. Under noncatalytic conditions, hydride sources are chiefly used for their reduction. Recently developed Ni-catalyzed one-pot reductive activation of esters and amides followed by tandem C-CO bond cleavage-decarbonylation facilitates their cleavage to aromatic hydrocarbons. Isolation and characterization of key reaction intermediates provide insight into this acyl C-O bond activation pathway.

In this article, a novel series of (E)-3-(3,4,5-trimethoxyphenyl)acrylic acid (TMCA) amide derivatives 1-18 were designed and synthesized by a facile and one-pot step, which were achieved with good yields using 1-hydroxybenzotriazole (HOBT) and 1-(3-Dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (EDCI) as activation system. All the synthesized derivatives were biologically evaluated for their anticonvulsant, sedative activity and neurotoxicity using the maximal electroshock (MES) model, sc-pentylenetetrazol (PTZ) model, pentobarbital sodium-induced sleeping model, and locomotor activity tests, respectively. Among them, compounds 4, 9 and 16 exhibited good anticonvulsant activity in primary evaluation. Furthermore, compound 4 is the most effective anticonvulsant and sedative agent in subsequent tests, while the low threshold of toxicity of compound 4 is vigilant. Compounds 9 and 16 also performed significantly anticonvulsant activity in subsequent tests with weak toxicity. The molecular modeling experiments also predicted good binding interactions of the obtained active molecules with the GABA transferas. Therefore, it could be concluded that the synthesized derivatives 4, 9 and 16 would represent useful lead compounds for further investigation in the development of anticonvulsant and sedative agents.

Convergent synthesis of 4,6-unsubstituted 5-acy1-2aminodihydropyrimidines using Weinreb amide

A method of convergent synthesis of novel 4,6-unsubstituted 5-acyl-2-aminodihydropyrimidines 7 is developed. The synthetic intermediate of 7, 4,6-unsubstituted 2-aminodihydropyrimidines 9 having a Weinreb amide at the 5-position, is prepared by the sequential Staudinger/aza-Wittig/cyclization reactions of (E)-tert-buty1{3-azido-2-Imethoxy(methyl)carbamoyljallyl}carbamate (E)-10. The transformation of the Weinreb amide of 9 to an acyl group proceeds smoothly by a substitution reaction using aryllithiums or alkyllithiums in the presence of a catalytic amount of BF3 etherate, affording 7 in good to high yield. The N-protecting group of 7 can be easily removed to obtain N-unsubstituted 2-amino5-acyldihydropyrimidines 8, and the derivatives are observed as a single isomer in H-1 NMR spectroscopy. All dihydropyrimidines in this study were hitherto unavailable and difficult to synthesize by conventional methods. (C) 2017 Elsevier Ltd. All rights reserved.

Traditional hydrogen bonding donors controlled colorimetric selective anion sensing in tripodal receptors: First-naked-eye detection of cyanide by a tripodal receptor via fluoride displacement assay

Here in we report iris (3-aminopropyl) amine based tripodal receptors L. L(1 )and L-2 which were functionalized with 4-nitrophenyl moieties having thio-urea, amide and sulfonamide as hydrogen bonding moieties respectively, shows a strong selectivity towards cyanide. A competitive colorimelric assay with L in the presence of fluoride ion suggests that the cyanide ion is much capable of displacing the bound fluoride, showing a sharp distinguishable color change. To the best of our knowledge, this is the first example of a naked-eye detection of cyanide via fluoride displacement assay by a tripodal receptor and such a displacement phenomenon is not observes in the cases of L-1 and L-2, instead the receptor L-1 binds nitrate and cyanide; L-2 binds dihydrogen phosphate and cyanide. Using this assay, we have proposed an AND logic gate using L.F- and CN-. (C) 2019 Elsevier B.V. All rights reserved.

One-Pot Synthesis to Quinone-Based Diaza[3.3]cyclophanes

A simple one-pot synthesis to [3.3]cyclophanes that involves quinone moieties was found. The protocol tolerates a variety of amines that include aliphatic and aromatic structures with different functional groups, such as hydroxy groups, amides, and terminal double and triple bonds. The straightforward synthesis can be performed by a twofold N-alkylation reaction with 2,5-bis(bromomethyl)-3,6-dimethyl-1,4-benzoquin-one (1). Neither anhydrous nor inert conditions are required. Various amines can be employed without any activating groups, several functionalities at end groups are tolerated, and the cyclophanes generated can be easily modified or embedded into larger molecular architectures. The redox-active nature of these cyclophanes allows their use in electron-transfer processes.

Molecular preservation in mammoth bone and variation based on burial environment

Biomolecules preserved in fossils are expanding our understanding of the biology and evolution of ancient animals. Molecular taphonomy seeks to understand how these biomolecules are preserved and how they can be interpreted. So far, few studies on molecular preservation have considered burial context to understand its impact on preservation or the potentially complementary information from multiple biomolecular classes. Here, we use mass spectrometry and other analytical techniques to detect the remains of proteins and lipids within intact fossil mammoth bones of different ages and varied depositional setting. By combining these approaches, we demonstrate that endogenous amino acids, amides and lipids can preserve well in fossil bone. Additionally, these techniques enable us to examine variation in preservation based on location within the bone, finding dense cortical bone better preserves biomolecules, both by slowing the rate of degradation and limiting the extent of exogenous contamination. Our dataset demonstrates that biomolecule loss begins early, is impacted by burial environment and temperature, and that both exogenous and endogenous molecular signals can be both present and informative in a single fossil.

Discovery of amide-bridged pyrrolo[2,3-d]pyrimidines as tumor targeted classical antifolates with selective uptake by folate receptor alpha and inhibition of de novo purine nucleotide biosynthesis

We previously showed that classical 6-substituted pyrrolo[2,3-d]pyrimidine antifolates bind to folate receptor (FR) alpha and the target purine biosynthetic enzyme glycinamide ribonucleotide formyltransferase (GARFTase) with different cis and trans conformations. In this study, we designed novel analogs of this series with an amide moiety in the bridge region that can adopt both the cis and trans lowest energy conformations. This provides entropic benefit, by restricting the number of side-chain conformations of the unbound ligand to those most likely to promote binding to FR alpha and the target enzyme required for antitumor activity. NMR of the most active compound 7 showed both cis and trans amide bridge conformations in similar to 1:1 ratio. The bridge amide group in the best docked poses of 7 in the crystal structures of FR alpha and GARFTase adopted both cis and trans conformations, with the lowest energy conformations predicted by Maestro and evidenced by NMR within 1 kcal/mol. Compound 7 showed similar to 3-fold increased inhibition of FR alpha-expressing cells over its non-restricted parent analog 1 and was selectively internalized by FR alpha over the reduced folate carrier (RFC), resulting in significant in vitro antitumor activity toward FR alpha-expressing KB human tumor cells. Antitumor activity of 7 was abolished by treating cells with adenosine but was incompletely protected by 5-aminoimidazole-4-carboxamide (AICA) at higher drug concentrations, suggesting GARFTase and AICA ribonucleotide formyltransferase (AICARFTase) in de novo purine biosynthesis as the likely intracellular targets. GARFTase inhibition by compound 7 was confirmed by an in situ cell-based activity assay. Our results identify a first-in-class classical antifolate with a novel amide linkage between the scaffold and the side chain aryl L-glutamate that affords exclusive selectivity for transport via FR alpha over RFC and antitumor activity resulting from inhibition of GARFTase and likely AICARFTase. Compound 7 offers significant advantages over clinically used inhibitors of this class that are transported by the ubiquitous RFC, resulting in dose-limiting toxicities.
