Evolution of PIKK family kinase inhibitors: A new age cancer therapeutics

Phosphatidylinositol-3 kinase-related kinases (PIKKs) belong to a family of atypical serine/threonine kinases in humans. They actively participate in a diverse set of cellular functions such as meiotic, V(D)J recombination, chromosome maintenance, DNA damage sensing and repair, cell cycle progression and arrest. ATR, ATM, DNA-PKcs, mTOR and hSMG are the members of the PIKK family that play an important role in in cancer cell proliferation, autophagy, and cell survival to radio and chemotherapy. Thereby targeting these PIKK kinases in cancer along with chemo/radiotherapy agents, can help in differential cytotoxicity towards cancer cell over the normal cell. In this review, we compile the various small molecule kinase inhibitors with respect to structural and strategic targeting of PIKK family members. Rapalogs, AZD8055, AZD2014, OSI-027, INK-128, MLN0128, VX970, NVP-BEZ235, Torin2, AZ20, and AZ31 are the diverse scaffolds which have successfully made into the pre-clinical trials either as mono or combinatorial therapy for the treatment of various human cancers. Their synthesis and pre-clinical trial highlight the challenges associated in the development process.

Recent therapeutic progress of chalcone scaffold bearing compounds as prospective anti-gout candidates

Gout is a common form of arthritis characterized by severe and sudden pain for a long duration, swelling, tenderness, lingering discomfort, and acute redness in the joint situated at the big toe due to the accumulation of monosodium urate (MSU) crystals. Though, at present these drugs have limited pharmacodynamics benefits with the emergence of adverse effects. Therefore, the modern trend has perceived a shift towards the regular use of natural products and tailored-approach, which have revolutionized the prescription pattern from traditional combinations to unexplored classes of drugs. Natural product classes such as chalcones have received adequate attention for treating these severe ailments with a better margin of safety. Chalcone or 1,3-diphenyl-2-propene-1-one or benzylideneacetophenone are the natural scaffold comprising of two aromatic rings connected together by a three-carbon alpha, beta unsaturated carbonyl link. The chalcone scaffold bearing synthetic (polyhydroxylated chalcones, 3,5,2,4-tetrahydroxychalcone, trans-chalcone) and natural (sappanchalcone, okanin, hesperidin methylchalcone, quercetin chalcone, 4-hydroxyderricin, isobavachalcone, xanthoangelol F, xanthoangelol, and xanthoangeleol B) compounds have been found to exhibit tremendous anti-gout activity by completely suppressing the active disease proliferating enzyme, xanthine oxidase (XO) as well as by suppressing the activation of nuclear factor kappa-light-chain-enhancer of activated B cells (NF-kappabeta), along with preventing the formation and influx of pro-inflammatory factors. The overview glance of this scientific review will provide information to the scientists working in the pharmaceutical as well as allied science fields in fabricating, screening, and exploring the abundant hidden chemical classes based on the provided structural, chemical, and miscellaneous aspects.

Decisive properties of solvent able to form gels with syndiotactic polystyrene

The thermoreversible gel formation of syndiotactic polystyrene (SPS) was studied in detail. Even if SPS solutions with high concentrations did not form gels, there were the cases where SPS formed gels at lower concentrations of SPS, which favor the formation of a polymer-solvent molecular compound. Sixty-two solvent compounds were examined in regard to whether they could form SPS gels. All the compounds whose molecular volume is between 69 and 153 A3 and whose Fedors’ solubility parameter value is between 8.8 and 12.3 (cal/cm3)1/2 were found to produce SPS gels as solvent. Since a solvent molecule that can form SPS gel can be a guest of SPS delta co-crystalline phase, it has become convenient to find functional molecules able to co-crystallize with SPS by taking into account these conditions of gelation solvent molecules.

Intermolecular hydrogen bonding interactions of furan, isoxazole and oxazole with water

Intermolecular hydrogen bonding between furan, isoxazole, oxazole and water has been analysed using theoretical methods. Ab initio and DFT methods have been employed to optimize the adducts of heterocycles with single water molecule. The stabilization energies associated with the adduct formation are evaluated at B3LYP/AUG-cc-pVDZ//B3LYP/6-31+G*, MP2/AUG-cc-pVDZ//MP2/6-31+G* levels and corrected for zero-point vibrational energies (ZPE) and basis set superposition error (BSSE) using counterpoise method. Natural bond orbital analysis (NBO) at MP2/6-31+G* has also been carried out to study electron delocalization of these adducts. The hydrogen bond acceptor ability of heteroatoms and p cloud of the ring are compared. In the heterocyclic molecules with nitrogen and chalogen in 1, 2 and 1, 3 positions, the nitrogen is better hydrogen bond acceptor than the chalcogen in all cases.

Gold-catalyzed heterocyclic syntheses through alpha-imino gold carbene complexes as intermediates

Gold carbene complexes have been recognized as common intermediates in gold-catalyzed organic syntheses. In this field, alpha-imino gold carbene complexes, in the last few years, have emerged as valuable intermediates toward the synthesis of N-heterocycles. This review is dedicated toward formulating a comprehensive compilation of the different methodologies for heterocyclic synthesis, postulating the participation of alpha-imino gold carbene complexes as intermediates. In addition to the scarce examples involving the direct formation of alpha-imino diazo compounds from gold decomposition, the use of nitrogenated nucleophiles, through an initial attack on gold-activated alkynes followed by gold retrodonation and expulsion of a leaving group, constitutes the most commonly employed strategy for achieving this target. This review has been divided into different sections as follows according to the type of N-nucleophile used: azides, aza-ylides, 2H-azirines, isoxazoles and their derivatives, indazoles, and triazapentalenes. A large number of heterocycles, ranging from five- to seven-membered rings, have been efficiently synthesized following this methodology.

The pyrolysis of isoxazole revisited: A new primary product and the pivotal role of the vinylnitrene. A low-temperature matrix isolation and computational study

This paper describes the pyrolysis of parent isoxazole and of its 5-methyl and 3,5-dimethyl derivatives by the high-pressure pulsed pyrolysis method, where activation of the precursor molecules occurs predominantly by collisions with the host gas (Ar in our case), rather than with the walls of the pyrolysis tube, where catalyzed processes may occur. The products were trapped at 15 K in Ar matrices and were characterized by vibrational spectroscopy. Thereby, hitherto unobserved primary products of pyrolysis of isoxazole and of its 5-methyl derivative, 3-hydroxypropenenitrile or 3-hydroxybutenenitrile, respectively, were observed. E-Z photoisomerization could be induced in the above hydroxynitriles. On pyrolysis of isoxazole, ketenimine and CO were observed as decomposition products, but this process did not occur when the 5-methyl derivative was pyrolyzed. Instead, the corresponding ketonitrile was formed. In the case of 3,5-dimethylisoxazole, 2-acetyl-3-methyl-2H-azirine was detected at moderate pyrolysis temperatures, whereas at higher temperatures, 2,5-dimethyloxazole was the only observed rearrangement product (next to products of dissociation). These findings are rationalized on the basis of quantum chemical calculations. Thereby it becomes evident that carbonyl-vinylnitrenes play a pivotal role in the observed rearrangements, a role that had not been recognized in previous theoretical studies because it had been assumed that vinylnitrenes are closed-shell singlet species, whereas they are in fact open-shell singlet biradicaloids. Thus, the primary processes had to be modeled by the multiconfigurational CASSCF method, followed by single-point MR-CISD calculations. The picture that emerges from these calculations is in excellent accord with the experimental findings; that is, they explain why some possible products are observed while others are not.

Directing-Group-Assisted Transition-Metal-Catalyzed Direct C-H Oxidative Annulation of Arenes with Alkynes for Facile Construction of Various Oxygen Heterocycles

The most recent advances in the construction of oxygen heterocycles by the directing-group-assisted transition-metal-catalyzed direct oxidative annulation of arenes with diverse alkynes are summarized in this review. More than 140 recent research papers and many closely related reviews are referenced in this paper. Nine different oxygen heterocycles frameworks are discussed. Several traditional transition-metal catalysts as well as some classical non-noble metals are utilized to promote the annulation. Three plausible controlling models are disclosed to clarify the excellent regioselectivity outcomes achieved in case of unsymmetrical alkyne substrates. 1 Introduction 2 Coumarins 3 I socoumarins and Their Analogues 4 2-Pyrones and Their Analogues 5 Chromones and Chroman-4-ones 6 Chromenes and Isochromenes 7 Fused Polycyclic Oxygen Heteroaromatics 8 Benzofurans, Dihydrobenzofurans, and Furans 9 Phthalides and Benzofuranones 10 Benzoxepines 11 Conclusion.

Recent advances in computing heteroatom-rich five- and six-membered ring systems

Recent developments in computer technology and the increasing efficiency and accuracy of current ab initio and density functional programs allow the investigation of increasingly complex systems. Molecules that could be treated only at the semiempirical level ten years ago can now be computed at the density functional or the MP2 level with basis sets of double-zeta quality. Very often, these calculations are accurate enough to explain experimental findings, and consequently many experimental studies are augmented by quantum chemical calculations. However, in many cases just a few kilocalories per mole may decide between different reaction mechanisms, different explanations of physical effects, or even a preferred tautomer or conformer. Since the inherent errors of MP2 and DFT calculations are still significantly larger than chemical accuracy, high-level calculations are mandatory for many problems. This holds particularly true for the investigation of reaction {A figure is presented}{A figure is presented} barriers involving bond-breaking processes. Although these problems have been recognized by many investigators, a substantial number of papers lack sufficient accuracy. This accuracy problem appears to be more severe for heteroatom-rich species than for other systems, in particular for systems with adjacent heteroatoms. However, DFT calculations were found to cope surprisingly well with the geometric parameters of most of these systems. As is common in heterocyclic chemistry, many studies concern tautomeric equilibria. While quantum chemical calculations are straightforward for the question of the most stable isomer, experiments are sometimes very demanding. Therefore, quantum chemistry can easily provide answers that may require substantial experimental effort. Comparatively few studies concern the investigation of entire reaction paths. This is much more demanding than computing a limited number of tautomers, of course, but usually provides a very detailed picture of the reaction mechanism. In certain cases, it was only possible to judge the nature of a chemical reaction on the basis of quantum chemical calculations. Most studies concerning pyrimidines originate from biochemical questions. Since these systems are dominated by hydrogen-bonding and/or dispersion contributions, methods beyond the Hartree-Fock level are mandatory. The success of quantum chemical studies in this field is impressive and many effects could be explained on the basis of these theoretical investigations.
