Discovery of BMS-986202: A Clinical Tyk2 Inhibitor that Binds to Tyk2 JH2

A search for structurally diversified Tyk2 JH2 ligands from 6 (BMS-986165), a pyridazine carboxamide-derived Tyk2 JH2 ligand as a clinical Tyk2 inhibitor currently in late development for the treatment of psoriasis, began with a survey of six-|membered heteroaryl groups in place of the N-methyl triazolyl moiety in 6. The X-ray co-crystal structure of an early lead (12) revealed a potential new binding pocket. Exploration of the new pocket resulted in two frontrunners for a clinical candidate. The potential hydrogen bonding interaction with ThrS99 in the pocket was achieved with a tertiary amide moiety, confirmed by the X-ray co-crystal structure of 29. When the diversity search was extended to nicotinamides, a single fluorine atom addition was found to significantly enhance the permeability, which directly led to the discovery of 7 (BMS-986202) as a clinical Tyk2 inhibitor that binds to Tyk2 JH2. The preclinical studies of 7, including efficacy studies in mouse models of IL-23-driven acanthosis, anti-CD40-induced colitis, and spontaneous lupus, will also be presented.

Anticancer and apoptotic activity of biologically synthesized zinc oxide nanoparticles against human colon cancer HCT-116 cell line- in vitro study

Aim of this study was to synthesize the safe and stable zinc oxide nanoparticles (ZnONPs) from the leaves of Artocarpus heterophyllus. The alter in the color of the leaf extract dark brown upon addition of zinc nitrate Zn(NO3) confirms the formation of Zinc Oxide nanoparticles (ZnONPs). UV-VIS spectrophotometric analysis showed lambda max at 235 nm while Fourier transform infra-red (FTIR) spectroscopy showed various amines and amides are involved in the stabilization of ZnONPs. Energy dispersive X -rays (EDX) confirms the presence of zinc. Transmission electron microscopy (TEM) analysis revealed particle size ranges from 12 to 24 nm. These observed characteristic of nanoparticles are extremely useful in anticancer activities against HCT-116 colon cancer cell line. These ZnONPs showed IC50 value at 20 mu g/ml while on normal Vero cell line showed less effective by MTT assay. Furthermore, these nanoparticles were evaluated for apoptotic activity by acridine orange/ethidium bromide (AO/EB) double staining method showed the membrane blebbing and chromatin condensation.

[Fe{(eta(5)-C5H4)N(SiMe(2)tBu)}(2)Al](2): A Stable Redox-Functionalized Dialumane(4)

The diaminoferrocene derivatives [Fe{(eta(5)-C5H4)NHR}(2)] (1H(2), a: R = SiMe(2)tBu, b: R = CMe(2)tBu, c: R = C6H3-2,6-iPr(2)) were converted into the lithium amides 1aLi(2) – 1cLi(2) by treatment with nBuLi. The reaction of these amides with AlI3 furnished 1aAlI – 1cAlI. The reduction of 1aAlI with KC8 afforded 1aAl-Al1a, which is a new stable dialumane(4) with exclusively tricoordinate Al atoms and only the second example so far of a tetraamino-substituted compound of this kind. 1bH(2), 1cH(2), 1aLi(2), [1c{Li(THF)(3)}(2)], [1aAlI(OEt2)], 1cAlI, 1aAl-Al1a center dot 1/2Et(2)O and 1aAl-Al1a center dot 1/2C(7)H(8) were structurally characterized by single-crystal X-ray diffraction.

Transparent nanocomposite coatings based on epoxy and layered double hydroxide: Nonisothermal cure kinetics and viscoelastic behavior assessments

Layered double hydroxide (LDH) has a particular place in clay family because of its flame retardant action. The nanoplatelet-like structure of LDH makes possible development of polymer composites with cationic or anionic nature structures in which macromolecules are positioned in between nanoplatelet galleries. In this work, neat epoxy and its transparent nanocomposite coatings with sodium dodecylbenzene sulfonate (SDBS)-modifled LDHs; Mg-Al and Zn-Al LDHs, were prepared and their cure kinetics and viscoelastic behavior were tracked through nonisothermal calorimetric and dynamic mechanical analyses. The higher progression of crosslinking in the epoxy network was observed for epoxy/Zn-Al LDH nanocomposites, while activation energy of cure reaction took a higher value for Mg-Al LDH-incorporated systems. Moreover, epoxy/Mg-Al LDH system revealed higher value of storage modulus and glass transition temperature thanks to larger galleries of Mg-Al nanoplatelets. Network formation in the presence of SDBS-modified Zn-Al LDH nanoplatelets was facilitated due to the action of Zn metal as an adduct with a lone-pair of oxygen atom of epoxy leading to an enhanced epoxy ring-opening. Viscoelastic behavior of transparent coatings containing Zn-Al LDH and Mg-Al LDH was studied through temperature -sweep test at various frequencies to compare the results of calorimetric and thermo-mechanical analyses.

The effects of mepiquat chloride on the lateral root initiation of cotton seedlings are associated with auxin and auxin-conjugate homeostasis

BackgroundMepiquat chloride (MC) is a plant growth regulator widely used in cotton (Gossypium hirsutum L.) production to suppress excessive vegetative growth, increase root growth and avoid yield losses. To increase root growth, cotton seeds were treated with MC to increase the number of lateral root (LRs) and improve drought resistance. An increased indole-3-acetic acid (IAA) pool appeared to correlate with LR growth, and the principal source of IAA in germinating seeds is IAA conjugates. Here, the role of IAA homeostasis and signaling was investigated in cotton seedlings treated with MC.ResultsIn the present research, MC significantly increased endogenous IAA levels in the roots, which promoted lateral root initiation (LRI) by upregulating GhARF7/19 and GhLBD18s and subsequently increasing LR quantity and elongation. The levels of IAA-amide conjugates significantly decreased in MC-treated seedlings compared with untreated control seedlings. Sixteen members of the cotton IAA amidohydrolase (IAH) gene family were identified, of which GhIAR3a, GhIAR3b, GhILR1, GhILL3 and GhILL6 were expressed during cotton seed germination. Compared with those in untreated control seedlings, the expression levels of GhIAR3a, GhIAR3b, GhILR1 and GhILL6 in the MC-treated seedlings were markedly elevated. The GhIAR3a/b and GhILR1 genes were cloned and expressed in Escherichia coli; these recombinant proteins exhibited hydrolytic activity that could cleave IAA-phenyalanine (Phe), IAA-methionine (Met), IAA-glycine (Gly) and IAA-leucine (Leu) in vitro, while only GhIAR3a hydrolyzed IAA-alanine (Ala) efficiently. The content of GhIAR3a, as detected via an established sandwich enzyme-linked immunosorbent assay (ELISA), increased in the MC-treated seedlings compared with the untreated control seedlings. In addition, the Arabidopsis iar3 mutant was less responsive to MC-induced LR growth than was wild type.ConclusionsThese findings suggested that MC application could mediate IAA homeostasis via increased IAA levels from IAA-amide conjugate hydrolysis by accelerating IAH gene expression, which might promote LRI and increase the LR quantity and elongation.

Oligomerization of the HECT ubiquitin ligase NEDD4-2/NEDD4L is essential for polyubiquitin chain assembly

The NEDD4-2 (neural precursor cell-expressed developmentally down-regulated 4-2) HECT ligase catalyzes polyubiquitin chain assembly by an ordered two-step mechanism requiring two functionally distinct E2 approximate to ubiquitin-binding sites, analogous to the trimeric E6AP/UBE3A HECT ligase. This conserved catalytic mechanism suggests that NEDD4-2, and presumably all HECT ligases, requires oligomerization to catalyze polyubiquitin chain assembly. To explore this hypothesis, we examined the catalytic mechanism of NEDD4-2 through the use of biochemically defined kinetic assays examining rates of I-125-labeled polyubiquitin chain assembly and biophysical techniques. The results from gel filtration chromatography and dynamic light-scattering analyses demonstrate for the first time that active NEDD4-2 is a trimer. Homology modeling to E6AP revealed that the predicted intersubunit interface has an absolutely conserved Phe-823, substitution of which destabilized the trimer and resulted in a 10(4)-fold decrease in k(cat) for polyubiquitin chain assembly. The small-molecule Phe-823 mimic, N-acetylphenylalanyl-amide, acted as a noncompetitive inhibitor (K-i = 8 +/- 1.2 mm) of polyubiquitin chain elongation by destabilizing the active trimer, suggesting a mechanism for therapeutically targeting HECT ligases. Additional kinetic experiments indicated that monomeric NEDD4-2 catalyzes only HECT approximate to ubiquitin thioester formation and monoubiquitination, whereas polyubiquitin chain assembly requires NEDD4-2 oligomerization. These results provide evidence that the previously identified sites 1 and 2 of NEDD4-2 function in trans to support chain elongation, explicating the requirement for oligomerization. Finally, we identified a conserved catalytic ensemble comprising Glu-646 and Arg-604 that supports HECT-ubiquitin thioester exchange and isopeptide bond formation at the active-site Cys-922 of NEDD4-2.

New Variations on the Theme of Gold(III) C boolean AND N boolean AND N Cyclometalated Complexes as Anticancer Agents: Synthesis and Biological Characterization

A series of novel (C<^>N<^>N) cyclometalated Au complexes of general formula [Au(bipy(dmb)-H)X][PF6] (bipya(dmb)-H = C<^>N<^>N cyclometalated dimethylbenzy1)-2,2′-bipyridine) were prepared with a range of anionic ligands X in the fourth coordination position, featuring C (alkynyl)-, N-, 0-, or S-donor atoms. The X ligands are varied in nature and include three coumarins, 4-ethynylaniline, saccharine, and thio-beta-D-glucose tetraacetate, the tripeptide glutathione (GSH), and a coumarinsubstituted amide derived from 4-ethynylaniline. The gold(I) complex [Au-(C(2)ArNHCOQ)(PPh3)] (HC(2)ArNHCOQ = N-(4-ethynylphenyl)-2-oxo-2H-chromene-3-carboxamide) was also prepared for comparison. The new compounds were fully characterized by means of analytical techniques, including NMR, absorption, and emission spectroscopy. The crystal structures of three cyclometalated Aunt complexes and of the Au-I derivative were solved by single-crystal X-ray diffraction. The antiproliferative activity of the new Au-III cyclometalated derivatives was evaluated against cancer cells in vitro. According to the obtained results, only complexes 3-PF6 and 5-PF6, featuring coumarins as ancillary ligands and endowed with high redox stability in solution, display antiproliferative effects, with 5-PF6 being the most potent, while all of the others are scarcely active to nonactive in the selected cell lines. In order to study the reactivity of the compounds with biomolecules, the interaction of complexes 3-PF6 and 5-PF6 with the protein cytochrome c and the amino acids cysteine and histidine was analyzed by electrospray ionization mass spectrometry (ESI MS), showing adduct formation only with Cys after at least 1 h incubation. Furthermore, the parent hydroxo complex [Au(bipy(dmb)-H)(OH)][PF6] (1OH-PF6) was investigated in a competitive assay to determine the protein vs oligonucleotide binding preferences by capillary zone electrophoresis (CZE) coupled to ESI-MS. Of note, the compound was found to selectively form adducts with the oligonucleotide over the protein upon ligand exchange with the hydroxido ligand. Adduct formation occurred within the first 10 min of incubation, demonstrating the preference of 1OH-PF6 for nucleotides in this setup. Overall, the obtained results point toward the possibility to selectively target DNA with gold(III) organometallics.

Multigram-scale flow synthesis of the chiral key intermediate of (-)-paroxetine enabled by solvent-free heterogeneous organocatalysis

The catalytic enantioselective synthesis of the chiral key intermediate of the antidepressant (-)-paroxetine is demonstrated as a continuous flow process on multi-gram scale. The critical step is a solvent-free organocatalytic conjugate addition followed by a telescoped reductive amination-lactamization-amide/ester reduction sequence. Due to the efficient heterogeneous catalysts and the solvent-free or highly concentrated conditions applied, the flow method offers key advances in terms of productivity and sustainability compared to earlier batch approaches.

Synthesis of matrinic amide derivatives containing 1,3,4-thiadiazole scaffold as insecticidal/acaricidal agents

In continuation of our program aimed at the development of natural product-based pesticidal agents, a series of matrinic amide derivatives containing 1,3,4-thiadiazole scaffold were prepared, and their insecticidal and acaricidal activities were evaluated against Mythimna separata and Tetranychus cinnabarinus. Some compounds exhibited potent insecticidal and acaricidal activities. It suggested that R-1 as a nitro group and R-2 as a fluorine atom, were important for the insecticidal activity; R-1 as the electron-donating groups and R-2 as the methyl group, were necessary for the acaricidal activity.
