The rotational spectrum of the isoxazole-argon complex was studied in the microwave region between 3 and 25 GHz using a pulsed molecular beam Fourier transform microwave spectrometer. The rotational constants were found to be A = 4974.2534(2) MHz, B = 1382.291 788(24) MHz, and C = 1371.647 236(36) MHz. The centrifugal distortion constants are D?J = 5.624 21(30) kHz, D?K = -27.8794(256) kHz, D?JK = 34.8064(34) kHz, delta?J = -0.010 48(24) kHz, and R?6 = -0.000 40(18) kHz. The diagonal elements and one off-diagonal element of the quadrupole coupling tensor were determined to be chiaa = -0.113 10(48) MHz, chibb = 1.941 36(87) MHz, chicc = -1.82826(45) MHz, and chibc = ±4.8954(22) MHz. Using BSSE-corrected supermolecular Moller-Plesset (MP) perturbation theory at second (MP2) and fourth order (MP4(SDTQ)) with a (14s10p2d1f)[7s4p2d1f] basis set for argon and a 6-31G(+sd+sp) basis for isoxazole, stability (MP2 308 cm-1; MP4 283 cm-1), equilibrium geometry, charge distribution, and multipole moments of the complex were determined. Argon adopts a position above the ring plane (Ar-ring distance R = 3.44 (exp), 3.53 (MP2, re), 3.55 A (MP4, re) shifted from the center of the ring toward the NO bond. The complex is predominantly stabilized by dispersion interactions while its geometry is more a result of exchange repulsion forces, which direct Ar toward the most electronegative atoms of the ring, namely O and N.

Introduction: Tyrosine kinases are involved in the control of several biological processes and have been recognized as hot spots of oncogenic transformation, thus representing a major therapeutic target. Dysregulated activation of RET kinase, either through point mutations or gene fusions, is accountable for a significant fraction of thyroid carcinomas, as well as a minor population of lung cancers. Two drugs are currently available for the treatment of medullary thyroid carcinoma and two additional compounds have been approved for differentiated thyroid carcinoma. Several other molecules are under preclinical and clinical evaluation. Areas covered: This review covers the most recent patent literature (2012?2015) describing compounds with activity against the RET kinase, trying to catch a view of the next generation of potential anti-RET drugs. Expert opinion: RET has been a focus of molecularly targeted efforts for over a decade. However, none of the drugs currently on the clinical stage were specifically developed to hit RET, which was rather an off-target. Besides, only two of four drugs have activity on metastatic medullary carcinoma. Therefore, there is still a need of additional, more potent and more specific RET inhibitors, which will hopefully emerge from the new generation of compounds disclosed in most recent patents.

Curcumin is a multi-functional pharmacologically safe natural agent with proven cytoprotective effects to healthy human cells. In this study, a new series of sulfonamides with curcumin scaffold were synthesized, characterized and investigated for their carbonic anhydrase isoenzyme I (human) and II (bovine) isoforms. The structures of newly synthesized compounds were described by IR, 1H NMR and 13C NMR spectral data. Compound 14 showed the Ki value of 0.99 muM with highest inhibitory activity among all other synthesized compounds against hCA-I enzyme. Similarly enzyme kinetic studies of compound 14, 16 and 30 against bCAII enzyme showed Ki values of 0.71, 0.67 and 0.71 muM respectively. Our biological assays results showed that most of active compounds have similar inhibitory activities compared to standard acetazolamide drug. The molecular docking predicted binding modes showed that these compounds bind with hCA-1 enzyme in similar fashion.

The present review provides a survey on the structural features, synthetic methodologies, and reactions of phenyl sulfonylacetophenone, considered to be one of the most important synthons in the field of synthetic organic chemistry. beta-Ketosulfone is an active C?H acid which has been widely used as a nucleophile in many organic transformations. It has been used for synthesis of five- and six-membered ring systems containing one or two heteroatoms. In addition, it has been used as a starting material for synthesis of fused heterocycles, cyclopropane, cyclopentene, and cyclohexanone derivatives. beta-Ketosulfone has been used for synthesis of gamma- and delta-ketosulfones, 1,4-diketones, amides, ethers, and substituted benzene derivatives due to its high synthetic importance. It is a reactive intermediate in electrophilic reactions such as halogenation, alkylation, arylation, heteroarylation, and coupling reactions, and is involved in other types of reaction such as Diels?Alder condensation with aldehydes and desulfonylation. The mechanistic pathways of these reactions and their important synthetic applications are discussed herein.

Heterocycles play an essential role in modern pharmaceutical and agrochemical developments, representing a very common structural unit in marketed drugs. Over the 46 new drugs approved in 2017 by the FDA, 25 contain in their structure a heterocyclic core. The development of novel and straightforward labeling strategies for the effective insertion of carbon isotopes into heterocylic scaffolds is an inspiring and vibrant field of research. The use of carbon-11, carbon-13, and carbon-14 isotopes is well established in life science and particularly in pharmaceutical and agrochemical industry. Their introduction into small organic molecules represents a crucial step for the radiochemists. Because the labeling should occur in metabolically stable positions and in the shortest synthetic route, their incorporation into the heterocycles represents a viable solution. This review summarizes recent contributions to this area of research through the analysis of different industrial and academic cases.

Cancer remains as one of the leading causes of death in the world and as a result there is a pressing need for the development of novel and effective treatments. The goal in cancer chemotherapy is to provide cytotoxic effect to prevent tumor growth. Nowadays, drugs that cause damage to DNA or inhibit DNA synthesis by antimetabolite characteristics that may prevent cell division through microtubule inhibition, inhibition of topoisomerase and inhibition of the key tyrosine kinases are used in cancer treatment. Among other factors, inherent and acquired resistance to treatment and the dose-limiting toxicity caused by the narrow therapeutic window of many cancer drugs are major obstacles in effective cancer therapy. Since clinically useful drugs have problems with toxicity, drug resistance and bioavailability, there is an ongoing effort to find new compounds that may be safer or more effective. A literature survey revealed that a number of biologically active scaffolds have important affects in the development of antiproliferative agents. This article summarizes the antiproliferative agents containing indole, pyrazole or isoxazole backbones and combretastatin A-4 analogues with various mechanism of actions that have published in recent years.

Tuberculosis (TB) is a global health disaster and is a wide-reaching hitch. The improper use of antibiotics in chemotherapy of TB patients led to the current problem of tuberculosis therapy which gives rise to Multi-Drug Resistant (MDR) strains. Nitrogen heterocycles including azole compounds are an important class of therapeutic agent with electron-rich property. Azole-based derivatives easily bind with the enzymes and receptors in organisms through noncovalent interactions, thereby possessing various applications in medicinal chemistry. Research on azoles derivatives have been expansively carried out and have become one of the extremely active area in recent years and the progress is quite rapid. A genuine attempt to review chemistry of azoles and to describe various azole-based compounds synthesized in the last two decades having promising antitubercular potential is described in the present article. It is hopeful that azole compounds may continue to serve as an important direction for the exploitation of azole-based antitubercular drugs with better curative effect, lower toxicity, less side effects, especially fewer resistances and so on.

Chagas disease is caused by the protozoan parasite Trypanosoma cruzi. It is endemic in South and Central America and recently has been found in other parts of the world, due to migration of chronically infected patients. The current treatment for Chagas disease is not satisfactory, and there is a need for new treatments. In this work, we describe the optimization of a hit compound resulting from the phenotypic screen of a library of compounds against T. cruzi. The compound series was optimized to the level where it had satisfactory pharmacokinetics to allow an efficacy study in a mouse model of Chagas disease. We were able to demonstrate efficacy in this model, although further work is required to improve the potency and selectivity of this series.

Malaria is a life-threatening infectious disease caused by Plasmodium parasites. Plasmepsins (proteolytic enzymes of the parasite) have been considered as promising targets for the development of antimalarial drugs. To date, much knowledge has been obtained regarding the interactions of inhibitors with plasmepsins, as well as the structure-activity relationships of the inhibitors. The discovery and characterization of the plasmepsin inhibitors that bind in open flap conformation have led to several inhibitor classes that show high selectivity over other human aspartic proteases. This Perspective addresses the flexibility of the plasmepsins that leads to inhibitor binding to the open flap conformation, summarizes known nonpeptidomimetic plasmepsin inhibitors, and discusses the role of the inhibitor flap pocket substituent.
