G protein-coupled receptors as promising cancer targets

G protein-coupled receptors (GPCRs) regulate an array of fundamental biological processes, such as growth, metabolism and homeostasis. Specifically, GPCRs are involved in cancer initiation and progression. However, compared with the involvement of the epidermal growth factor receptor in cancer, that of GPCRs have been largely ignored. Recent findings have implicated many GPCRs in tumorigenesis, tumor progression, invasion and metastasis. Moreover, GPCRs contribute to the establishment and maintenance of a microenvironment which is permissive for tumor formation and growth, including effects upon surrounding blood vessels, signaling molecules and the extracellular matrix. Thus, GPCRs are considered to be among the most useful drug targets against many solid cancers. Development of selective ligands targeting GPCRs may provide novel and effective treatment strategies against cancer and some anticancer compounds are now in clinical trials. Here, we focus on tumor related GPCRs, such as G protein-coupled receptor 30, the lysophosphatidic acid receptor, angiotensin receptors 1 and 2, the sphingosine 1-phosphate receptors and gastrin releasing peptide receptor. We also summarize their tissue distributions, activation and roles in tumorigenesis and discuss the potential use of GPCR agonists and antagonists in cancer therapy.

Corrosion inhibition of aluminum in 1.0M HCl solution by some nonionic surfactant compounds containing five membered heterocyclic moiety

Three nonionic surfactant (NIS) compounds containing five membered heterocyclic moiety were synthesized and identified from spectral data such as IR and 1HNMR spectra. The inhibiting effect of NIS compounds toward the corrosion of aluminium (Al) in 1.0MHCl solutions was examined using weight loss, thermometric, electrochemical impedance spectroscopy and galvanostatic polarization techniques. The results obtained indicated that the three compounds are good corrosion inhibitors. The inhibition efficiency increases as the concentration of the NIS compounds increases, as well as the decrease in temperature, surface tension and interfacial tension. The polarization measurement showed that these inhibitors are acting as mixed inhibitors mainly cathodic. The inhibition was interpreted in view of spontaneous adsorption of NIS compounds onto the Al surface by forming a stable chelating ring between the Al surface and NIS molecules. The adsorption mechanism obeys Freundlich isotherm. The activated thermodynamic parameters such Ea, DeltaH* and DeltaS*were calculated and clarified.

Understanding unconventional routes to impurities from drugs in hydrolytic conditions

Introduction: Hydrolytic degradation is the most common cause of formation of impurities or degradation products in drugs during different stages of drug product development and/or shelf life of the drug/product. Degradation products formed by hydrolysis of ester, amide, urethane, sulfonamide, sulfonate and ether linkages, and of nitrile, hydroxyl and amino groups in drugs can be conveniently predicted and identified. Many drugs are known to degrade to such expected conventional hydrolytic degradation products, and the mechanisms of such degradations are also well known and reported. However, many drugs are reported to degrade under hydrolytic conditions to products, which cannot be justified by the conventional hydrolytic reactions. Objectives: Though structures of such unconventional hydrolytic products can be characterized through different spectral techniques, but there is a need to understand the mechanisms of such unconventional hydrolytic reactions in order to help in establishing intrinsic stability characteristics of a drug. Methodology: In the present review, we have studied and critically analysed all possible reports on hydrolytic degradation of various dugs to provide a thorough insight into unconventional routes of hydrolytic degradations of drugs. The various unconventional hydrolytic reactions found responsible for degradation of drugs are classified as oxidation, dehydrogenation, coupling/condensation, N-alkylation, C-C bond cleavage, C-N bond cleavage, dehalogenation, cyclization, decarboxylation and hydroxylation. Discussion: Varied types of reactions under hydrolytic conditions are triggered/controlled by the nature of substituent (s) across or around the susceptible bonds/groups. The mechanisms for such unconventional hydrolytic reactions have been discussed or proposed with support from the standard literature. The contents are expected to enable an analyst and a drug formulator to predict various possible as well as seemingly improbable hydrolytic degradation products of a drug well ahead of systematic forced degradation studies.

The antifungal activity of naphthoquinones: An integrative review

Naphthoquinones are the most commonly occurring type of quinones in nature. They are a diverse family of secondary metabolites that occur naturally in plants, lichens and various microorganisms. This subgroup is constantly being expanded through the discovery of new natural products and by the synthesis of new compounds via innovative techniques. Interest in quinones and the search for new biological activities within the members of this class have intensified in recent years, as evidenced by the evaluation of the potential antimicrobial activities of quinones. Among fungi of medical interest, yeasts of the genus Candida are of extreme importance due to their high frequency of colonization and infection in humans. The objective of this review is to describe the development of naphthoquinones as antifungals for the treatment of Candida species and to note the most promising compounds. By using certain criteria for selection of publications, 68 reports involving both synthetic and natural naphthoquinones are discussed. The activities of a large number of substances were evaluated against Candida albicans as well as against 7 other species of the genus Candida. The results discussed in this review allowed the identification of 30 naphthoquinones with higher antifungal activities than those of the currently used drugs.

Stacking Interactions between 9-Methyladenine and Heterocycles Commonly Found in Pharmaceuticals

Complexes of 9-methyladenine with 46 heterocycles commonly found in drugs were located using dispersion-corrected density functional theory, providing a representative set of 408 unique stacked dimers. The predicted binding enthalpies for each heterocycle span a broad range, highlighting the strong dependence of heterocycle stacking interactions on the relative orientation of the interacting rings. Overall, the presence of NH and carbonyl groups lead to the strongest stacking interactions with 9-methyadenine, and the strength of -stacking interactions is sensitive to the distribution of heteroatoms within the ring as well as the specific tautomer considered. Although molecular dipole moments provide a sound predictor of the strengths and orientations of the 28 monocyclic heterocycles considered, dipole moments for the larger fused heterocycles show very little correlation with the predicted binding enthalpies.

Abstract: An efficient strategy for synthesizing of 3-substituted bis-isoxazole ether bearing 2-chloro-3-pyridyl under microwave radiation was reported. The reactive regioselectivity was improved by changing mainly the solvent and acid-binding agent. 3-(2-Chloropyridin-3-yl)-5-(((3-substituted phenyl isoxazol-5-yl)methoxy)methyl)isoxazoles were synthesized in 31?92% yields and were characterized by FT-IR, HRMS, 1H and 13C NMR spectroscopy. The single crystal of 3-(2-chloropyridin-3-yl)-5-(((3-(p-tolyl)isoxazol-5-yl)methoxy)methyl)isoxazole was obtained, and the structure of compound has also been determined by X-ray diffraction technique. Weak intra- and intermolecular C?H???O interactions and a C?H???pi interaction link molecules into a three-dimensional network. The results showed that the synthesized compounds belonged to triclinic system, and their regioselectivity depended on the solvent and acid-binding agent. The merits of this method include the environmentally friendly, efficient, simple operation, and higher regional selectivity. Graphic abstract: An efficient synthesis of 3-substituted bis-isoxazole ethers was developed via 1,3-dipolar cycloaddition reaction starting from 3-substituted phenyl-5-((prop-2-yn-1-yloxy))methyl)isoxazoles and (Z)-2-chloro-N-hydroxynicotinimidoyl chloride using NaHCO3 as an acid-binding agent in THF solvent-dissolved trace water under catalyst-free microwave-assisted conditions.
