Effect of commonly used organic solvents on Aldehyde oxidase-mediated Vanillin, Phthalazine and Methotrexate oxidation in human, rat and mouse liver subcellular fractions

1. Aldehyde oxidase (AOX) is a cytosolic molybdoflavoprotein enzyme widely distributed across many tissues. In this study, we report the effect of commonly used organic solvents such as dimethyl sulfoxide (DMSO), acetonitrile (ACN), methanol and ethanol on AOX activity in human, rat and mouse liver S9 fractions using vanillin, phthalazine and methotrexate as probe substrates. 2. Methanol was found to be the most potent solvent in inhibiting vanillic acid and 1-phthalazinone formation in comparison to DMSO, ACN and ethanol across the species tested, except 7-hydroxy methotrexate. 3. Treatment with these solvents at approximate IC50 (% v/v) concentrations showed significant reduction in Clint and Vmax of the probe substrates and also resulted in different effects on Km across the species. 4. Marked differences in the activity and affinity towards AOX were observed with different probe substrates with methotrexate showing least activity and affinity as compared to vanillin and phthalazine. 5. Overall, AOX activity seemed to be more resilient to the presence of organic solvents at higher concentrations in human and rodent species. These results suggest that low concentrations of organic solvents are acceptable for in vitro incubations involving AOX-mediated metabolism.

Chapter 4 The immunochemical/photochemical interface

In this chapter we have seen that the immunochemical reaction and chemiluminescent reaction can be interfaced in a variety of ways though chiefly by coupling the chemiluminescent reactant itself (direct chemiluminescence labelling) to an immunoreactant, or by coupling another component of a chemiluminescent reaction other than the chemiluminescent molecule itself (indirect chemiluminescence labelling). It can be seen that the indirect labelling systems are incapable of achieving the level of simplicity offered by certain direct labelling systems, though some indirect labelling systems offer an equivalent level of sensitivity. The chemical techniques required to conjoin the chemiluminescent and immunochemical reactions are relatively well established though do not always permit substantial retention of light emission and immunoreactivity respectively. This is often dictated by the chemical properties of the species to be conjugated themselves. We have briefly considered the role of bioluminescent systems here even though they have yet to be widely accepted in the context of chemiluminescence immunoassay. Their true potential may yet be realized by the interface with genetic engineering techniques which will permit controlled biosynthesis of the appropriate enzymes.

Silver(i) complexes with quinazoline and phthalazine: Synthesis, structural characterization and evaluation of biological activities

New silver(i) complexes with quinazoline (qz) and phthalazine (phtz), [Ag(NO3)(qz)]n (1) and {[Ag(CH3CN)]2(mu-phtz)2}[BF4]2 (2), have been synthesized and structurally characterized by using different spectroscopic and single-crystal X-ray diffraction techniques. The obtained results revealed that the reaction of AgNO3 with qz at room temperature in a 2 :1 molar ratio led to the formation of the polynuclear complex 1. However, the reaction of AgBF4 with phtz under the same experimental conditions resulted in the formation of the dinuclear complex 2. The solution behaviour and air/light stability of these silver(i) complexes have been investigated. The complexes 1 and 2, along with the silver(i) salts used for their synthesis, were evaluated by in vitro antimicrobial studies against a panel of microbial strains that lead to many skin and soft tissue, respiratory, wound, and nosocomial infections. The obtained results indicate that all tested silver(i) compounds have good antibacterial activity with MIC values in the range from 1.5 to 15.6 mug mL-1 against the investigated strains. On the other hand, their antifungal activity against Candida albicans was moderate. In order to determine the therapeutic potential of 1 and 2, their antiproliferative effect on the normal human lung fibroblast cell line MRC5, hemolytic effect on red blood cells and embryotoxicity on zebrafish (Danio rerio) have also been evaluated.

A Synopsis of the Properties and Applications of Heteroaromatic Rings in Medicinal Chemistry

Five- and six-membered heteroaromatic rings and their benzo-fused homologues are well established as important structural elements in drug design and are well represented in approved drugs. The key properties of these heterocycles that are of?interest to medicinal chemists include lipophilicity, pKa, aromaticity, ionization potential, H-bond acceptor, and H-bond donor (N?H, O?H, C?H) capability, electron withdrawing effects, dipole values, and bond angles. The judicious and productive application of azoles and azines in drug design requires an understanding of the intrinsic physical chemical properties of the individual heterocycles and how these interact with substituents. In this article, the key properties of azole and azine heterocycles are summarized followed by a synopsis of applications where some of these factors play a role in drug?target interactions and/or potency.

Monoazole ligand platinum analogs

Disclosed herein are novel platinum-based analogs with a single substituted azole ligand: RN=NR7, wherein the RN=NR7 functional group is covalently bonded to the platinum through nitrogen of NR7. The analogs also have nitrogen donor ligands capable of forming hydrogen bonds with the bases in DNA or RNA, and one or more leaving groups which can be displaced by water, hydroxide ions or other nucleophiles, which is thought to form active species in vivo, and then, form cross-linked complexes between nucleic acid strands, principally between purines in DNA (or RNA), i.e., at the Guanine or Adenine bases, thereof. These platinum analogs may also be more easily transported into tumor cells, due to their increased lipophilicity and are likely to be useful as anti-neoplastic agents, and in modulating or interfering with the synthesis or replication or transcription of DNA or translation or function of RNA in vitro or in vivo, as they are potentially capable of forming a platinum coordinate complex with an intact or nascent DNA or RNA and thereby interfering with cellular synthesis, transcription or replication of nucleic acid polynucleotides.

Continuous amination of aryl/heteroaryl halides using aqueous ammonia in a Teflon AF-2400 tube-in-tube micro-flow reactor

The annual production of primary (hetero)arylamines has exceeded 6 million tons and has been extensively employed in the pharmaceutical, agrochemical, and materials industries. Catalyst-free and protecting group-free nucleophilic amination using ammonia represents a green and atom-economical method. However, due to the innate reactivity, chemical compatibility issue and the safety hazardous properties of ammonia gas, such transformation is still underused. By implementing a gas-permeable Teflon AF-2400 tube-in-tube system, diffusion of NH3 from aqueous ammonia to a reaction mixture for amination can be achieved in a continuous flow fashion. In this communication, we herein report the use of aqueous ammonia as the NH3 source in the amination of heteroaryl chorides to generate primary heteroaryl amines, providing a protocol that is green, economical and safe.

Blastomyces dermatitidis serine protease dipeptidyl peptidase IVA (DppIVA) cleaves ELR+CXC chemokines altering their effects on neutrophils

Blastomycosis elicits a pyogranulomatous inflammatory response that involves a prominent recruitment of neutrophils to the site of infection. Although neutrophils are efficiently recruited to the site of infection, this event is paradoxically coupled with the host’s inability to control infection by Blastomyces dermatitidis, the causative agent. The mechanisms underlying this characteristic pyogranulomatous response and inability of neutrophils to kill the yeast are poorly understood. We recently reported that the fungal protease dipeptidyl peptidase IVA (DppIVA) promotes B.?dermatitidis virulence by cleaving a dipeptide from the N-terminus of C?C chemokines and granulocyte/macrophage-colony stimulating factor, thereby inactivating them. Herein, we present evidence that DppIVA can also truncate the N-terminus of members of the ELR+CXC chemokine family, which are known to modulate neutrophil function. We show that the DppIVA cleaved form of human (h) CXCL-2, for example, hCXCL-2 (3-73), is a more potent neutrophil chemoattractant than its intact counterpart, but hCXCL-2 (3-73) is conversely impaired in its ability to prime the reactive oxygen species response of neutrophils. Thus, DppIVA action on ELR+CXC chemokines may promote the pyogranulomatous response that is typical of blastomycosis, while also explaining the inability of neutrophils to control infection.

Direct Arylation of Unactivated Alkanes with Heteroarenes by Visible-Light Catalysis

The functionalization of aliphatic C-H bonds is both a major challenge and a desirable goal in organic synthesis. Here, we describe the successful arylation of unactivated alkanes with heteroarenes by using iridium polypyridyl complexes as the photocatalyst and persulfate as the HAT catalyst precursor under visible-light irradiation. This reaction features good functional group tolerance and broad scope with regard to both alkane and heteroarene substrates (37 examples), which allows direct access to alkyl-substituted N-heteroarenes, a key structural motif in natural products and bioactive molecules.

Recent advances in the synthesis of biologically active cinnoline, phthalazine and quinoxaline derivatives

In the recent decades, N-heterocycles are widely used as versatile scaffolds for the development of biologically active compounds and considered as one of the privileged structures. Among the various N-heterocycles, benzodiazines, a series of bicyclic heterocycles in which benzene rings are fused with 6-membered heterocycles containing two nitrogens are especially interesting, due to their structural conciseness and usefulness as synthetic intermediates, and suitable physicochemical properties as potential drug candidates and chemical probes. For this reason, a series of synthetic methodologies for benzodiazines has been developed and generally used in organic and medicinal chemistry fields. Interestingly, synthesis of quinazoline, a kind of benzodiazine in which benzene is fused with pyrimidine, has been extensively reviewed, while cinnoline, phthalazine and quinoxaline, benzene fused with pyridazine or pyrazine, have been relatively less investigated. In this review, recent advances in the synthesis of biologically active benzodiazines, benzene ring-fused 6-membered heterocycles with two nitrogen atoms, cinnoline, phthalazine and quinoxaline, will be addressed. In each section, biological activities of various benzodiazines, recently served as novel scaffolds for drug discovery, are briefly summarized for comprehensive understanding of biological and medicinal significance in advance. Moreover, intensive investigation of the synthetic approaches to various benzodiazines such as cinnoline, phthalazine and quinoxaline is followed. It would hopefully be helpful for the readers who have interests in developing novel drug candidates and related useful chemical probes.

Phytochemical Profile, Pharmacological Attributes and Medicinal Properties of Convolvulus prostratus ? A Cognitive Enhancer Herb for the Management of Neurodegenerative Etiologies

Convolvulus prostratus Forssk., a nootropic herb used in traditional medicinal systems, is also frequently known by its taxonomic synonym Convolvulus pluricaulis. In Indian medicinal system ? Ayurveda ? it is named as Shankhpushpi. According to the ancient literature, this herb has been attributed with several therapeutic properties, such as anxiolytic, neuroprotective, antioxidant, analgesic, immunomodulatory, antimicrobial, antidiabetic and cardioprotective activities. This medicinal herb has been reported to contain many bioactive phytoconstituents, such as, alkaloid (convolamine), flavonoid (kaempferol) and phenolics (scopoletin, beta-sitosterol and ceryl alcohol), that have been ascribed to the observed medicinal properties. Several research teams across the globe have highlighted the neuro-pharmacological profile of C. prostratus, wherein, the neuroprotective, nootropic and neuro-modulatory roles have been described. Besides, role of C. prostratus extracts in neurodegeneration has been well demonstrated. Despite of such elaborative preclinical pharmacological profile, detailed clinical investigations and mechanistic mode-of-action studies of this important herb are yet to be executed. The present review is attempted to showcase the phytochemical profile, pharmacological attributes and medicinal information of C. prostratus; with comprehensive research gap analysis. It is hoped that the scientific update on the ethnomedicinal aspects of this herb would thrive research propagation and development of the CNS phytopharmaceuticals, originated from C. prostratus.
