J. published the artcile< Pentafluorophenyl-based single-chain polymer nanoparticles as a versatile platform towards protein mimicry>, COA of Formula: C30H36N4O2, the main research area is pentafluorophenyl single chain polymer nanoparticle protein mimicry versatile platform.

Proteins are biopolymers folded into 3D-structures and are omnipresent in biol. systems, where they fulfil a wide array of complex functions. Mimicking the exceptional characteristics of proteins with synthetic analogs may likewise give unprecedented control over a nanomaterial’s pharmacokinetic behavior, enabling controlled delivery of therapeutics or imaging agents. Recent advances in polymer science have enabled the formation of bio-inspired single-chain polymer nanoparticles (SCNPs), which are formed by intramol. collapse of individual polymer chains, and display sizes ranging from 5-20 nm. Here, we describe the preparation of SCNPs containing activated ester moieties, facilitating SCNP functionalization without altering its backbone structure. Pentafluorophenyl-functional SCNPs were prepared through intramol. thiol-Michael addition crosslinking of thiol-functional precursor copolymers. Post-formation functionalization of the resulting SCNPs through substitution of the activated pentafluorophenyl esters with a variety of amines resulted in a series of water-soluble SCNPs with fluorescent labels, ‘click’ functionality, amino acids and even peptides. This synthetic strategy offers a straightforward method towards SCNP modification and SCNP-protein hybrids, giving access to easily adjustable physicochem. properties and protein mimicry.

In the search of a potential backup for clopidogrel, the authors have initiated a HTS campaign designed to identify novel reversible P2Y12 antagonists. Starting from a hit with low micromolar binding activity, the authors report here the main steps of the optimization process leading to the identification of the preclin. candidate SAR216471, I. It is a potent, highly selective, and reversible P2Y12 receptor antagonist and by far the most potent inhibitor of ADP-induced platelet aggregation among the P2Y12 antagonists described in the literature. I displays potent in vivo antiplatelet and antithrombotic activities and has the potential to differentiate from other antiplatelet agents.

A new approach for regioselective incorporation of a sulfonamide unit to heteroarene scaffolds has been developed and is reported within. As a result, a variety of primary benzylic N-alkylsulfonamides have been prepared via a two-step (one pot) formation from the in situ reduction of an intermediate N-sulfonyl imine under mild, practical conditions. The compounds have been screened against a variety of cell lines for cytotoxicity effects using a Cell Titer Blue assay. The cell viability investigation identifies a subset of N-benzylic sulfonamides derived from the indole scaffold to be targeted for further development into novel mols. with potential therapeutic value. The most cytotoxic of the compounds prepared, I (R1 = Me, R2,R3 = H; R4 = 4-ClC6H4), exhibited higher potency than other well-known anticancer agents Indisulam and ABT-751.

A small library of 3-(5-imidazo[2,1-b]thiazolylmethylene)-2-indolinones were synthesized and screened according to protocols available at the National Cancer Institute (NCI). Some derivatives were potent antiproliferative agents, showing GI50 values in the nanomolar range. Remarkably, when most active compounds against leukemia cells were tested in human peripheral blood lymphocytes from healthy donors, were 100-200 times less cytotoxic. Some compounds, selected by the Biol. Evaluation Committee of NCI, were examined to determine tubulin assembly inhibition. Furthermore, flow cytometric studies performed on HeLa, HT-29, and A549 cells, showed that compounds and caused a block in the G2/M phase. Interestingly, these derivatives induced apoptosis through the mitochondrial death pathway, causing in parallel significant activation of both caspase-3 and -9, PARP cleavage and down-regulation of the anti-apoptotic proteins Bcl-2 and Mcl-1. Finally, compound was also tested in-vivo in the murine BL6-B16 melanoma and E0771 breast cancer cells, causing in both cases a significant reduction in tumor volume

RV521 is an orally bioavailable inhibitor of respiratory syncytial virus (RSV) fusion that was identified after a lead optimization process based upon hits that originated from a phys. property directed hit profiling exercise at Reviral. This exercise encompassed collaborations with a number of contract organizations with collaborative medicinal chem. and virol. during the optimization phase in addition to those utilized as the compound proceeded through preclin. and clin. evaluation. RV521 exhibited a mean IC50 of 1.2 nM against a panel of RSV A and B laboratory strains and clin. isolates with antiviral efficacy in the Balb/C mouse model of RSV infection. Oral bioavailability in preclin. species ranged from 42 to >100% with evidence of highly efficient penetration into lung tissue. In healthy adult human volunteers exptl. infected with RSV, a potent antiviral effect was observed with a significant reduction in viral load and symptoms compared to placebo.

A Pd-catalyzed dearomative methoxyallylation of 3-nitroindoles with readily available allyl carbonates was reported. Good yields (up to 86%) and diastereoselectivity (up to >20:1 dr) were obtained for a wide range of substrates. The compatibility of gram-scale synthesis and the relatively low catalyst loading (down to 1 mol % of [Pd]) enhanced the practicality of this method. The kinetic experiments indicated that the rate-determining step of this reaction was the nucleophilic attack of the alkoxide anion.

Nerve gas mimic binding with Rhodamine B ethylenediamine (1) was studied in organic media. Binding of the nerve gas mimic, di-Et chlorophosphate (DCP), with the probe generated a non-fluorescent intermediate and a fluorescent product. Fluorescent and non-fluorescent products generated were identified using mass spectrometry and X-ray crystallog. Time-dependent d. functional theory calculations were also used to investigate the electronic structure of the fluorescent probe in the ground and lowest lying π → π* singlet excited state. Though good agreement between theory and experiment can be obtained for the intense peak in the exptl. spectrum using non-hybrid functionals, care must be taken when modeling these complexes due to the appearance of an n → π* transition that is too low in energy and appears to fall in the shoulders of the π → π* transitions.
