Drug discovery is a laborious process with rising cost per new drug. Peptide macrocycles are promising therapeutics, though conformational flexibility can reduce target affinity and specificity. Recent computational advancements address this problem by enabling rational design of rigidly folded peptide macrocycles. Areas Covered: This review summarizes currently approved peptide macrocycle therapeutics and discusses advantages of mesoscale drugs over small molecules or protein therapeutics. It describes the history, rationale, and state of the art of computational tools, such as Rosetta, that allow the design of rigidly structured peptide macrocycles. The emerging pipeline for designing peptide macrocycle drugs is described, including current challenges in designing permeable molecules that can emulate the chameleonic behavior of natural macrocycles. Prospects for reducing computational cost and improving accuracy with emerging computational technologies are also discussed. Expert opinion: To embrace computational design of peptide macrocycle drugs, we must shift current attitudes regarding the role of computation in drug discovery, and move beyond Lipinski?s rules. This technology has the potential to shift failures to earlier in silico stages of the drug discovery process, improving success rates in costly clinical trials. Given the available tools, now is the time for drug developers to incorporate peptide macrocycle design into drug discovery pipelines.

A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, Formula: C16H16N2, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 1660-93-1, Name is 3,4,7,8-Tetramethyl-1,10-phenanthroline, molecular formula is C16H16N2. In a Review, authors is Durand, Jerome，once mentioned of 1660-93-1

During the last decade there has been increased interest in the development of homogeneous catalytic systems to promote homo- or copolymerization reactions of unsaturated hydrocarbons. This review is focused on systems based on palladium complexes with nitrogen-donor ligands and on their application as catalysts (or precatalysts) for co- and terpolymerization of carbon monoxide and olefins. Detailed catalytic performance is reported (productivity, molecular weight values and stereoregularity of the copolymers) allowing comparison between different systems. Particular attention will be addressed to the relationship between catalyst structure and structural features of the polymers synthesized. A comment on the mechanism involved in the various reactions is also given.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 1660-93-1, help many people in the next few years.Formula: C16H16N2

Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 1271-19-8, molcular formula is C10Cl2Ti, introducing its new discovery. category: catalyst-ligand

A radical merry-go-round. An electron is transferred from a titanocene(III) complex to the substrate and finally back to the catalyst in a novel atom-economical tandem reaction. Complex structures can be readily accessed (see scheme). The unprecedented mechanism involving a homolytic cleavage of a Ti-O bond is supported by DFT calculations.

Since conformation of the molecule plays a vital role in the activity of drug, we have investigated the DNA interaction of a chromium(III) complex with ligands in two conformations. Chromium(III) complexes derived from chiral binaphthyl Schiff base ligands, viz. R- and S-2,2?-bis(salicylideneamino) 1,1?-binaphthyl, have been synthesized and characterized by mass, IR, and electronic spectra. The interaction of these R- and S-binaphthyl Schiff base chromium(III) complexes with CT-DNA was investigated with the goal of examining whether the chirality has an influence on the chromium(III)-DNA binding properties. The difference in chirality of the ligand did not show any striking difference in binding properties. The binding constants for R and S conformers were estimated to be 18 (±0.4) × 103 and 9.4 (±0.3) × 103 M-1, respectively, through spectroscopic titrations. All the experimental results are suggestive that both the isomers are DNA groove binders. The results of steady-state as well as time-resolved fluorescence experiments, however, suggest that the R conformer has restricted mobility when bound to DNA because it is more deeply buried in the groove of DNA compared to the S isomer.

Macrocyclic [Fe(eta5-C5H4Se)2M(eta5-C5H4R)2]2 [M = Ti (1), Zr (2), Hf (3), R = H; and M = Zr (4), Hf (5), R = tBu] were prepared and characterized by 77Se NMR spectroscopy and the crystal structures of 1-3 and 5 were determined by single-crystal X-ray diffraction. The crystal structure of 4 is known and the complex is isomorphous with 5. 1-5 form mutually similar macrocyclic tetranuclear complexes in which the alternating Fe(C5H4Se)2 and M(C5H4R)2 centers are linked by selenium bridges. The thermogravimetric analysis (TGA) of 1-3 under a helium atmosphere indicated that the complexes undergo a two-step decomposition upon heating. The final products were identified using powder X-ray diffraction as FexMSe2, indicating their potential as single-source precursors for functional materials.

Although there are many methods for oxidizing alcohols on a small laboratory scale, many of these methods are problematic for larger-scale industrial application due to safety and environmental concerns.[1] For example, the use of stoichiometric chromium reagents is very undesirable. In the last 10 to 20 years, there has been a growing momentum in academic efforts to develop catalytic methods for the oxidation of alcohols.[2] There are a now a wide variety of methods that utilize a range of transition metals, enzymes, and organocatalysts as catalysts and employ a number of different terminal oxidants. In this chapter, we will focus on the use of nitroxyl radical based catalysts. Catalytic methods using this class of radicals have evolved in the last 10 years, and they have a number of advantages over many of the alternatives. For example, nitroxyl-based systems have superior substrate scope/functional-group tolerance compared to precious-metal catalysts. In the case of some industrial applications, the avoidance of precious metals is also an advantage from a cost and toxicity point of view.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.
