Biological Activity of Ionic Liquids and Their Application in Pharmaceutics and Medicine

Ionic liquids are remarkable chemical compounds, which find applications in many areas of modern science. Because of their highly tunable nature and exceptional properties, ionic liquids have become essential players in the fields of synthesis and catalysis, extraction, electrochemistry, analytics, biotechnology, etc. Apart from physical and chemical features of ionic liquids, their high biological activity has been attracting significant attention from biochemists, ecologists, and medical scientists. This Review is dedicated to biological activities of ionic liquids, with a special emphasis on their potential employment in pharmaceutics and medicine. The accumulated data on the biological activity of ionic liquids, including their antimicrobial and cytotoxic properties, are discussed in view of possible applications in drug synthesis and drug delivery systems. Dedicated attention is given to a novel active pharmaceutical ingredient-ionic liquid (API-IL) concept, which suggests using traditional drugs in the form of ionic liquid species. The main aim of this Review is to attract a broad audience of chemical, biological, and medical scientists to study advantages of ionic liquid pharmaceutics. Overall, the discussed data highlight the importance of the research direction defined as “Ioliomics”, studies of ions in liquids in modern chemistry, biology, and medicine.

Total Synthesis of (+)-Latrunculin A, an Ichthyotoxic Metabolite of the Sponge Latrunculia magnifica, and Its C-15 Epimer

Latrunculin A (1), an ichthyotoxic metabolite of the sponge Latrunculia magnifica with potent inhibitory action on microfilament-mediated processes involved in cell division, was synthesized via a convergent approach.Construction of a major segment of the latrunculin backbone was accomplished by means of a three-component coupling of aldehyde 24, beta-keto ester 27, and phosphonium salt 26, which established the conjugated E,Z-diene moiety of 31.The thiazolidinone subunit of 1 was elaborated in the form of 39 from L-cysteine and was linked to 35 without nitrogen protection.Final lactonization of 47 was carried out using the Mitsunobu protocol.A parallel sequence employing the epimeric seco acid 48 produced 15-epilatrunculin A.

Follicle-stimulating hormone (FSH) action on spermatogenesis: A focus on physiological and therapeutic roles

Background: Human reproduction is regulated by the combined action of the follicle-stimulating hormone (FSH) and the luteinizing hormone (LH) on the gonads. Although FSH is largely used in female reproduction, in particular in women attending assisted reproductive techniques to stimulate multi-follicular growth, its efficacy in men with idiopathic infertility is not clearly demonstrated. Indeed, whether FSH administration improves fertility in patients with hypogonadotropic hypogonadism, the therapeutic benefit in men presenting alterations in sperm production despite normal FSH serum levels is still unclear. In the present review, we evaluate the potential pharmacological benefits of FSH administration in clinical practice. Methods: This is a narrative review, describing the FSH physiological role in spermatogenesis and its potential therapeutic action in men. Results: The FSH role on male fertility is reviewed starting from the physiological control of spermatogenesis, throughout its mechanism of action in Sertoli cells, the genetic regulation of its action on spermatogenesis, until the therapeutic options available to improve sperm production. Conclusion: FSH administration in infertile men has potential benefits, although its action should be considered by evaluating its synergic action with testosterone, and well-controlled, powerful trials are required. Prospective studies and new compounds could be developed in the near future.

Synthesis of new azobenzene dyes clubbed with thiazolidinone moiety and their applications

Purpose: The purpose of this paper is to synthesize some new azobenzene dyestuffs clubbed with thiazolidinone moiety and their solicitation in dyeing polyester fabrics representing their antibacterial evaluation. Design/methodology/approach: Herein, the authors report the synthesis of new thiazolidinone moiety after the coupling of diazotized 4-aminoacetophenone with resorcinol. The newly synthesized dyes were characterized by IR, elemental analysis, mass spectroscopy and proton nuclear magnetic resonance (1H NMR) spectral studies. The characteristics of dyeing of these dyestuffs were evaluated at optimum conditions. Concurrent with dyeing of polyester fabric for synthesized dyes with their antibacterial activity was estimated. Antimicrobial activity of the dyed fabrics at different concentrations was evaluated against gram-positive and gram-negative bacteria. Findings: Synthesized azobenzene dyestuffs clubbed with thiazolidinone dyes were applied on polyester fabrics. It was remarked that the modified dyes exhibited better colourfastness properties. Furthermore, the synthesized dyes revealed antimicrobial activity against gram-positive and gram-negative bacteria. Research limitations/implications: The synthesized azobenzene dyes for polyester dyeing were not bore earlier. Practical implications: The azobenzene dyes were accountable for giving improved colourfastness properties on polyester fabrics. Social implications: The synthesized azobenzene derivatives are sensibly expensive and applicable dyes accompanied with good antimicrobial and anticancer activities. Originality/value: A common process could be affording textiles of colour and antibacterial assets. The newly synthesized dyes containing thiazolidinone moieties with azobenzene coupler showed interesting disperse colourant for polyester with good antibacterial activity.

Facile new industrial process for synthesis of teneligliptin through new intermediates and its optimization with control of impurities

Abstract: The present study is related to a commercially practicable new synthetic process for production of teneligliptin hydrobromide hydrate (1), a dipeptidyl peptidase-4 (DPP-4) inhibitor. Key strategies in the new process include preparation and isolation of new intermediates such as a better reactive nosyl derivative (3c) of l-proline methyl ester (2), its stereoselective substituted intermediate (5) with 1-(3-methyl-1-phenyl-1H-pyrazol-5-yl)piperazine (4) through SN2-type nucleophilic substitution, and isolation of carboxylic acid derivative 6 by deesterification of intermediate 5. The reaction conditions for preparation of new intermediates, and the additionally used coupling reaction for amidation and deprotection of N-Boc were optimized with control of impurities to improve the quality of drug molecule 1 with good yield. The developed synthetic strategy offers significant advantages over existing synthetic approaches, avoiding use of expensive reagents, long time consumption, and laborious procedures involving isolation of intermediates. The developed process for drug molecule 1, achieving overall yield of 37?39% over six sequential chemical transformations, enables rapid delivery of multi-kilogram quantities of the desired active pharmaceutical ingredient (API), meeting stringent purity requirements.

Open source drug discovery: Highly potent antimalarial compounds derived from the tres cantos arylpyrroles

The development of new antimalarial compounds remains a pivotal part of the strategy for malaria elimination. Recent large-scale phenotypic screens have provided a wealth of potential starting points for hit-to-lead campaigns. One such public set is explored, employing an open source research mechanism in which all data and ideas were shared in real time, anyone was able to participate, and patents were not sought. One chemical subseries was found to exhibit oral activity but contained a labile ester that could not be replaced without loss of activity, and the original hit exhibited remarkable sensitivity to minor structural change. A second subseries displayed high potency, including activity within gametocyte and liver stage assays, but at the cost of low solubility. As an open source research project, unexplored avenues are clearly identified and may be explored further by the community; new findings may be cumulatively added to the present work.
