Reactions of Bis(2-pyridyl)amine and Its Deprotonated Anion with Ruthenium and Osmium Carbonyl Complexes

The reactions and coordination geometry of bis(2-pyridyl)amine (Hdpa) and its deprotonated anion (dpa) can be effectively modified by the reaction conditions. Depending on the solvent system, the reaction of multinuclear ruthenium carbonyls such as Ru3(CO)2 and [Ru(CO) 3Cl2]2 with Hdpa at moderate reaction temperatures lead to low yields of a monomeric cis(CO), cis(Cl)-Ru(Hdpa)(CO)2Cl2 or a dimeric metal-metal-bonded [Ru(dpa)2(CO)2]2. In organic solvents high temperatures favor the formation of [Ru(dpa)2(CO)2] 2 from clustered Ru3(CO)12 and Hdpa. The high-temperature reactions in HCl solution can, in turn, be used for selective synthesis of cis(CO),cis(Cl)-Ru(Hdpa)(CO)2Cl2. dpa (deprotonated with CH3Li) readily reacts with [Ru(CO) 3Cl2]2, Ru3(CO)12, or H4Ru4(CO)12 in organic solvents, leading to [Ru(dpa)2(CO)2]2. Under the corresponding conditions Os carbonyls produce a new type of dpa-bridged dimer compound without a direct metal-metal bond, [Os(dpa)(CO)2(CH 3)]2, in addition to ruthenium dimer equivalent [Os(dpa)2(CO)2]2.

Design, synthesis and anti-influenza A virus activity of novel 2,4-disubstituted quinazoline derivatives

Four 2,4-disubstituted quinazoline series containing various amide moieties were designed and synthesized as new anti-influenza A virus agents using the strategies of bio-isosterism and scaffold hopping. Many of them exhibit potent in vitro anti-influenza A virus activity and low cytotoxicity (CC50: >100 muM). Particularly, compounds 10a5 and 17a show better activity (IC50: 3.70?4.19 muM) and higher selective index (SI: >27.03, >23.87, respectively) against influenza A/WSN/33 virus (H1N1), opening a new direction for quinazoline derivatives in anti-influenza A virus field.

Synthesis of an Fmoc-threonine bearing core-2 glycan: A building block for PSGL-1 via Fmoc-assisted solid-phase peptide synthesis

Selectins (L, E, and P) are vascular endothelial molecules that play an important role in the recruitment of leukocytes to inflamed tissue. In this regard, P-Selectin glycoprotein-1 (PSGL-1) has been identified as a ligand for P-Selectin. PSGL-1 binds to P-Selectin through the interaction of core-2 O-glycan expressing sialyl Lewisx oligosaccharide and the three tyrosine sulfate residues. Herein, we report the synthesis of threonine-linked core-2 O-glycan as an amino acid building block for the synthesis of PSGL-1. This building block was further incorporated in the Fmoc-assisted solid-phase peptide synthesis to provide a portion of the PSGL-1 glycopeptide.

Rational design of novel, potent small molecule pan-selectin antagonists

This report describes the first results of a rational hit-finding strategy to design novel small molecule antiinflammatory drugs targeting selectins, a family of three cellular adhesion molecules. Based on recent progress in understanding of molecular interaction between selectins and their natural ligands as well as progress in clinical development of synthetic antagonists like 1 (bimosiamose, TBC1269), this study was initiated to discover small molecule selectin antagonists with improved pharmacological properties. Considering 1 as template structure, a ligand-based approach followed by focused chemical synthesis has been applied to yield novel synthetic small molecules (MWr < 500) with a trihydroxybenzene motif, bearing neither peptidic nor glycosidic components, with nanomolar in vitro activity. Biological evaluation involves two kinds of in vitro assays, a static molecular binding assay, and a dynamic HL-60 cell attachment assay. As compared to controls, the novel compounds showed improved biological in vitro activity both under static and dynamic conditions. Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Recommanded Product: 33821-94-2, you can also check out more blogs about33821-94-2

Identification of nicotinamide phosphoribosyltransferase (NAMPT) inhibitors with no evidence of CYP3A4 time-dependent inhibition and improved aqueous solubility

Herein we report the optimization efforts to ameliorate the potent CYP3A4 time-dependent inhibition (TDI) and low aqueous solubility exhibited by a previously identified lead compound from our NAMPT inhibitor program (1, GNE-617). Metabolite identification studies pinpointed the imidazopyridine moiety present in 1 as the likely source of the TDI signal, and replacement with other bicyclic systems was found to reduce or eliminate the TDI finding. A strategy of reducing the number of aromatic rings and/or lowering c Log D7.4 was then employed to significantly improve aqueous solubility. These efforts culminated in the discovery of 42, a compound with no evidence of TDI, improved aqueous solubility, and robust efficacy in tumor xenograft studies.

Synthesis of novel heterobranched beta-cyclodextrins having beta-D-N-acetylglucosaminyl-maltotriose on the side chain

From a mixture of N-acetylglucosaminyl-beta-cyclodextrin (GlcNAc-betaCD) and lactose, beta-D-galactosyl-GlcNAc-betaCD (Gal-GlcNAc-betaCD) was synthesized by the transfer action of beta-galactosidase.
