Electron stimulated desorption from condensed pyrimidine and pyridazine

Low energy electron (LEE) interactions and the formation of transient negative ions play a dominant role in radiation-induced dissociation of condensed-phase biomolecules (e.g. in radiotherapy). Here we present data on the LEE-induced dissociation and desorption of the DNA/RNA-base and radiosensitizing agent analogues pyrimidine and pyridazine. Vapors of each molecule were condensed on either a Pt or Ar substrate to form a multilayer film or a submonolayer molecular target, respectively. These were irradiated with electrons of 0-80 eV and the desorbing anionic and cationic fragments analysed via time of flight mass spectrometry. The detected cations are the same species seen in gas-phase mass spectra, albeit of differing relative intensity. Anion yield functions exhibit strong maxima, indicating that transient negative ions contribute significantly, via dissociative electron attachment (DEA), to molecular dissociation below 20 eV. For both molecules, the < 5 eV shape resonances, seen experimentally and predicted by theory, do not result in fragment desorption. The main anionic fragments are H- and CN- for both molecules, additionally the fragments C-, CH- C2H- and CHN- desorb from pyrimidine and C- and C2H- from pyridazine, with some resonances lying above the ionization limit. Pyrimidine shows higher anion desorption yields than pyridazine for all species except H-. The anion signal also comprises dipolar dissociation (DD), investigated in both anionic and cationic yield functions. From analysis of anion and cation yields, fragmentation pathways are suggested. The direct ionization pathway provides information on the appearance energies for cations and their production processes in condensed phase.

Synthesis and biological activity of a new class of insecticides: the N-(5-aryl-1,3,4-thiadiazol-2-yl)amides

BACKGROUNDOptimization studies on a high-throughput screening (HTS) hit led to the discovery of a series of N-(6-arylpyridazin-3-yl)amides with insecticidal activity. It was hypothesized that the isosteric replacement of the pyridazine ring with a 1,3,4-thiadiazole ring could lead to more potent biological activity and/or a broader sap-feeding pest spectrum. The resulting N-(5-aryl-1,3,4-thiadiazol-2-yl)amides were explored as a new class of insecticides. RESULTSSeveral methods for 2-amino-1,3,4-thiadiazole synthesis were used for the preparation of key synthetic intermediates. Subsequent coupling to variously substituted carboxylic acid building blocks furnished the final targets, which were tested for insecticidal activity against susceptible strains of Aphis gossypii (Glover) (cotton aphid), Myzus persicae (Sulzer) (green peach aphid) and Bemisia tabaci (Gennadius) (sweetpotato whitefly). CONCLUSIONStructure-activity relationship (SAR) studies on both the amide tail and the aryl A-ring of novel N-(5-aryl-1,3,4-thiadiazol-2-yl)amides led to a new class of insecticidal molecules active against sap-feeding insect pests.

Discovery of BMS-986260, a Potent, Selective, and Orally Bioavailable TGF beta R1 Inhibitor as an Immuno-oncology Agent

Novel imidazole-based TGF beta R1 inhibitors were identified and optimized for potency, selectivity, and pharmacokinetic and physicochemical characteristics. Herein, we report the discovery, optimization, and evaluation of a potent, selective, and orally bioavailable TGF beta R1 inhibitor, 10 (BMS-986260). This compound demonstrated functional activity in multiple TGF beta-dependent cellular assays, excellent kinome selectivity, favorable pharmacokinetic properties, and curative in vivo efficacy in combination with anti-PD-1 antibody in murine colorectal cancer (CRC) models. Since daily dosing of TGF beta R1 inhibitors is known to cause class-based cardiovascular (CV) toxicities in preclinical species, a dosing holiday schedule in the anti-PD-1 combination efficacy studies was explored. An intermittent dosing regimen of 3 days on and 4 days off allowed mitigation of CV toxicities in one month dog and rat toxicology studies and also provided similar efficacy as once daily dosing.

Developing pyridazine-3-carboxamides to be CB2 agonists: The design, synthesis, structure-activity relationships and docking studies

Herein, we described the design and synthesis of a series of pyridazine-3-carboxamides to be CB2-selective agonists via a combination of scaffold hopping and bioisosterism strategies. The compounds were subjected to assessment of their potential activities through calcium mobilization assays. Among the tested derivatives, more than half of these compounds exhibited moderate to potent CB2 agonist activity. Six compounds showed EC50 values below 35 nM, and several derivatives also exhibited significantly enhanced potency and high selectivity at the CB2 receptor over the CB1 receptor. Specifically, compound 26 showed the highest CB2 agonist activity (EC50 = 3.665 +/- 0.553 nM) and remarkable selectivity (Selectivity Index > 2729) against CB1. In addition, logPs of some representative compounds were measured to display significantly decreased values in comparison with GW842166X. Furthermore, docking simulations were conducted to explain the interaction mode of this series. (C) 2017 Elsevier Masson SAS. All rights reserved.

Design, Synthesis, and Molecular Mechanism Studies of N-Phenylisoxazoline-thiadiazolo[3,4-a]pyridazine Hybrids as Protoporphyrinogen IX Oxidase Inhibitors

Protoporphyrinogen oxidase (PPO, EC 1.3.3.4) is an important target for green agrochemical discovery. Herein, a novel N-phenylisoxazoline-thiadiazolo[3,4-a]pyridazine herbicidal active scaffold was designed by the scaffold hybridization strategy. Systematic structural optimization enabled the discovery of a series of derivatives with excellent weed control at 9.375-150 g ai/ha by the post-emergent application. Some derivatives exhibited improved Nicotiana tabacum PPO (NtPPO)-inhibitory activity than fluthiacet-methyl. Of these, 2b, with K-i = 21.8 nM, displayed higher weed control than fluthiacet-methyl at the rate of 12-75 g ai/ha, and selective to maize at 75 g ai/ha. In planta, 2b was converted into a bioactive metabolite S (K-i = 4.6 nM), which exhibited 4.6-fold more potency than 2b in inhibiting the activity of NtPPO. Molecular dynamics simulation explained that 5 formed stronger pi-pi interaction with Phe392 than that of 2b. This work not only provides a promising lead compound for weed control in maize fields but is also helpful to understand the molecular mechanism and basis of the designed hybrids.

A simple and cost-efficient technique to generate hyperpolarized long-lived N-15-N-15 nuclear spin order in a diazine by signal amplification by reversible exchange

Signal Amplification by Reversible Exchange (SABRE) is an inexpensive and simple hyperpolarization technique that is capable of boosting nuclear magnetic resonance sensitivity by several orders of magnitude. It utilizes the reversible binding of para-hydrogen, as hydride ligands, and a substrate of interest to a metal catalyst to allow for polarization transfer from para-hydrogen into substrate nuclear spins. While the resulting nuclear spin populations can be dramatically larger than those normally created, their lifetime sets a strict upper limit on the experimental timeframe. Consequently, short nuclear spin lifetimes are a challenge for hyperpolarized metabolic imaging. In this report, we demonstrate how both hyperpolarization and long nuclear spin lifetime can be simultaneously achieved in nitrogen-15 containing derivatives of pyridazine and phthalazine by SABRE. These substrates were chosen to reflect two distinct classes of N-15(2)-coupled species that differ according to their chemical symmetry and thereby achieve different nuclear spin lifetimes. The pyridazine derivative proves to exhibit a signal lifetime of similar to 2.5 min and can be produced with a signal enhancement of similar to 2700. In contrast, while the phthalazine derivative yields a superior 15 000-fold N-15 signal enhancement at 11.7 T, it has a much shorter signal lifetime.

Construction of Vesicles, Micro/Nanorods and Ultralong Nanotubes through the Self-Assembly of Non-Classical Amphiphiles with Rigid Conformation

Amphiphilic molecules have long been regarded as an important class of supramolecular building blocks for the fabrication of nanomaterials. While most previous researches have mainly focused on amphiphlies with flexible structures, in this work, four novel amphiphiles possessing wholly-rigid skeletons have been designed and synthesized. These molecules were built by using 4,4′-bipyridin-1-ium or viologen as hydrophilic moieties and phenyl or biphenyl as hydrophobic segments, bridged by a pyridazine unit. Their self-assembly behavior has been investigated by scanning electron microscopy (SEM), atomic force microscopy (AFM) and transmission electron microscopy (TEM), which revealed they could self-assemble into well-ordered nanoarchitectures with various morphologies such as vesicles, micro/nanorods and nanotubes in water or methanol, depending on their hydrophilic/hydrophobic fraction ratios.

Highly efficient solution processed OLEDs based on iridium complexes with steric phenylpyridazine derivative

Four bis-cyclometalated iridium complexes (Ir(tpp)(2)(pic) (1), Ir(tpp)(2)(paz) (2), Or(ttp)(2)(pic) (3) and Or (ttp)(2)(paz) (4) with phenylpyridazine derivative ligands were synthesized under mild reaction conditions, in which tpp (tppH = 3, 6-bis(4- (trifluoromethyl)phenyl)pyridazine) or ttp (ttpH = (5 s, 8 s)-1,4-bis(4- (trifluommethyl))-diphenyl-5,6,7,8-tetrahydro-5,8-thanophthalazine) was used as the primary ligand and pyridine2-carboxylate (pic) or paz (pazH = 2-(3-(trifluoromethyl)-1H-pyrazol-5-yl)pyridine) were used as ancillary ligand. The coordination arrangement of complexes 1-3 was revealed by the single X-ray structural analyses. All complexes showed strong emissions with peaks ranged from 519 to 547 nm and quantum efficiencies of 0.55-0.80. By introducing sterically hindered bicyclo [2.2.2] oct-2-ene groups in the primary ligands of complexes 3 and 4, their molecular interactions are strongly restrained in solid. The organic light-emitting diodes (OLEDs) were fabricated with complexes 2 (device A) and 4 (device B) as dopants. The better device performances with a maximum current efficiency of 50.5 cd A(-1) and a maximum external quantum efficiency of 14.9% are achieved by device B, along with smaller efficiency roll-off, which is attributed to the effect of alkyl steric groups and relative more matched energy levels in device.
