Metal- and solvent-free reaction of quinolines with two molecules of aryltrifluoroacetylacetylenes afforded 3-arylethynyl-3-trifluoromethyl-1,3-oxazinoquinolines in up to 92% yields. The formation of a zwitterionic intermediate in the first step triggered a multistep domino reaction. This one-pot synthesis opens an easy access to novel quinoline derivatives bearing trifluoromethyl, acetylene and ketone functions, thus providing a powerful tool for drug design.

Oxazolidinone-quinolone hybrids, which combine the pharmacophores of a quinolone and an oxazolidinone, were synthesised and shown to be active against a variety of susceptible and resistant Gram-positive and Gram-negative bacteria. The nature of the spacer greatly influences the antibacterial activity by directing the mode of action, that is quinolone- and/or oxazolidinone-like activity. The best compounds in this series have a balanced dual mode of action and overcome all types of resistance, including resistance to quinolones and linezolid, in clinically relevant Gram-positive pathogens.

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.COA of Formula: C12H8ClFN2O3, you can also check out more blogs about100361-18-0

The first anion-binding organocatalyzed enantioselective Reissert-type dearomatization of diazarenes has been developed. This reaction represents a synthetic challenge since diazarenes have various reactive sites. The use of a chiral tetrakistriazole as a C-H-based hydrogen-donor catalyst allowed the straightforward highly regio- and enantioselective synthesis of a variety of chiral diazaheterocycles.

The reactivities toward biomolecules of a series of three dirhodium(II,II) complexes that possess an increasing number of accessible axial coordination sites are compared. In cis-[Rh2(OAc)2(np) 2]2+ (1; np = 1,8-naphthyridine) both axial sites are available for coordination, whereas for cis-[Rh2(OAc) 2(np)(pynp)]2+ (2; pynp = 2-(2-pyridyl)1,8-naphthyridine) and cis-[Rh2(OAc)2(pynp)2]2+ (3) the bridging pynp ligand blocks one and two of the axial coordination sites in the complexes, respectively. The electronic absorption spectra of the complexes are consistent with strong metal-to-ligand charge transfer transitions at low energy and ligand-centered peaks localized on the np and/or pynp ligands in the UV and near-UV regions. Time-dependent density functional theory calculations were used to aid in the assignments. The three complexes exhibit metal-centered oxidations and reductions, localized on the aromatic ligands. The ability of the complexes to stabilize duplex DNA and to inhibit transcription in vitro is greatly affected by the availability of an open axial coordination site. The present work shows that open axial coordination sites on the dirhodium complexes are necessary for biological activity.

Background: Serine/threonine protein kinase CK2 is involved in the regulation of a number of cellular functions such as cell growth, proliferation, differentiation and apoptosis. Increased activity of CK2 is associated with the development of different types of cancer, inflammatory response, pain and virus infections. Therefore, protein kinase CK2 is an attractive molecular target for the development of small-molecular inhibitors which can be important compounds for pharmaceutical application. Objective: The main aim of this research is to identify novel chemical class of CK2 inhibitors with good lead-like properties. Methods: In order to find novel CK2 inhibitors, virtual screening experiments were performed using Autodock software. Best-scored compounds were tested in vitro using P32 radioactive kinase assay. Results: Small-molecular inhibitors of protein kinase CK2 were identified among the derivatives of 1,3-thiazole-5-carboxylic acid. The most active compound inhibited CK2 with IC50 value of 0.4 muM. Ligand efficiency for studied derivatives of 1,3-thiazole-5-carboxylic acid was in the range from 0.45 to 0.56 kcal/mol/non-hydrogen atom. Conclusion: Considering the fact that the lower limit for ligand efficiency parameter is 0.3, the identified CK2 inhibitors among the derivatives of 1,3-thiazole-5-carboxylic acid are excellent candidates for further lead optimization.

The utilization of CO2 via electrochemical reduction constitutes a promising approach toward production of value-added chemicals or fuels using intermittent renewable energy sources. For this purpose, molecular electrocatalysts are frequently studied and the recent progress both in tuning of the catalytic properties and in mechanistic understanding is truly remarkable. While in earlier years research efforts were focused on complexes with rare metal centers such as Re, Ru, and Pd, the focus has recently shifted toward earth-abundant transition metals such as Mn, Fe, Co, and Ni. By application of appropriate ligands, these metals have been rendered more than competitive for CO2 reduction compared to the heavier homologues. In addition, the important roles of the second and outer coordination spheres in the catalytic processes have become apparent, and metal-ligand cooperativity has recently become a well-established tool for further tuning of the catalytic behavior. Surprising advances have also been made with very simple organocatalysts, although the mechanisms behind their reactivity are not yet entirely understood. Herein, the developments of the last three decades in electrocatalytic CO2 reduction with homogeneous catalysts are reviewed. A discussion of the underlying mechanistic principles is included along with a treatment of the experimental and computational techniques for mechanistic studies and catalyst benchmarking. Important catalyst families are discussed in detail with regard to mechanistic aspects, and recent advances in the field are highlighted.
