Current status and future prospects of Marine Natural Products (MNPs) as antimicrobials

The marine environment is a rich source of chemically diverse, biologically active natural products, and serves as an invaluable resource in the ongoing search for novel antimicrobial compounds. Recent advances in extraction and isolation techniques, and in state-of-the-art technologies involved in organic synthesis and chemical structure elucidation, have accelerated the numbers of antimicrobial molecules originating from the ocean moving into clinical trials. The chemical diversity associated with these marine-derived molecules is immense, varying from simple linear peptides and fatty acids to complex alkaloids, terpenes and polyketides, etc. Such an array of structurally distinct molecules performs functionally diverse biological activities against many pathogenic bacteria and fungi, making marine-derived natural products valuable commodities, particularly in the current age of antimicrobial resistance. In this review, we have highlighted several marine-derived natural products (and their synthetic derivatives), which have gained recognition as effective antimicrobial agents over the past five years (2012?2017). These natural products have been categorized based on their chemical structures and the structure-activity mediated relationships of some of these bioactive molecules have been discussed. Finally, we have provided an insight into how genome mining efforts are likely to expedite the discovery of novel antimicrobial compounds.

Bioactive thiazole and benzothiazole derivatives

The heterocycles are the versatile compounds existing in almost all natural products and synthetic organic compounds, usually associated with one or the other biological activity. Among the heterocycles the thiazoles and benzothiazoles occupy a prominent position. They possess a broad range of biological activities and are foundin many potent biologically active molecules and drugs such as vitamin thiamine, sulfathiazol (antimicrobial drug), ritonavir (antiretroviral drug), abafungin (antifungal drug) and tiazofurin (antineoplastic drug). The thiazole moiety is abundantly found in natural products while benzothiazole moiety is rare. In this review we disclose the literature reports of thiazoles and benzothiazoles possessing different biological activities.

Acetonitrile-mediated synthesis of 2,4-dichloroquinoline from 2-ethynylaniline and 2,4-dichloroquinazoline from anthranilonitrile

2,4-Dichloroquinolines and 2,4-dichloroquinazolines were synthesized from 2-ethynylanilines and anthranilonitriles, respectively, using diphosgene in acetonitrile and heating at 130 C or 150 C for 12 hours. This reaction was applied to the synthesis of 4,6-dichloropyrazolo[3,4-d]pyrimidine (dichloro-9H-isopurine). The postulated mechanism is also described. Georg Thieme Verlag Stuttgart.

Synthesis, characterization and preliminary anti-inflammatory evaluation of 5-benzylidine thiazolidine-4-one derivatives

A series of four compounds which contain thiazolidine-4-one ring were synthesized and preliminarily assessed as anti-inflammatory agents with anticipated selectivity against COX-2 enzyme. The synthesized compounds structures have been recognised according to their spectral FT-IR and 1H NMR data. GOLD software was used to perform molecular docking study. The crystallographic structure of the molecular target cyclo-oxygenase enzyme-2 (COX-2) was taken from PDB database however, the celecoxib and naproxen were selected as a positive controls. The docking results of the newly synthesized compounds shown that they can enter the substrate-binding area of the active site .The compound (Ia) showed the highest PLP fitness,while compound (Ic) appeared to have the lowest binding ability compared to celecoxib which may be due to the presence of para nitro group that deactivates the ring system. Whereas In vivo acute anti-inflammatory effects of the synthesized compounds were evaluated in rats using egg-white induced edema model of inflammation. The tested compounds and the reference drug produced significant decrease in the paw edema with respect to the effect of propylene glycol 50%v/v (control group). Compounds Ia,b,d showed potent anti-inflammatory effect than naproxen (50mg/kg, i.p.) at 180 min., while compound Ic exhibited lower anti-inflammatory effect.

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.

(+)-Biotin: A Challenge for industrially viable total synthesis of natural products

The course of our investigation to develop an industrially viable total synthesis of (+)-biotin is described. Three synthetic approaches to (+)-biotin have been investigated to develop an efficient synthetic method using L-cysteine and thiolactone as a starting material and a key intermediate, respectively. Short steps, high yield and ease of operation of the approach would permit the hitherto most efficient access to (+)-biotin.

Synthesis of aryl-heteroaryl ureas (AHUs) based on 4-aminoquinoline and their evaluation against the insulin-like growth factor receptor (IGF-1R)

The insulin-like growth factor receptor (IGF-1R) is a receptor tyrosine kinase (RTK) involved in all stages of the development and propagation of breast and other cancers. The inhibition of IGF-1R by small molecules remains a promising strategy to treat cancer. Herein, we explore SAR around previously characterized lead compound (1), which is an aryl-heteroaryl urea (AHU) consisting of 4-aminoquinaldine and a substituted aromatic ring system. A library of novel AHU compounds was prepared based on derivatives of the 4-aminoquinoline heterocycle (including various 2-substituted derivatives, and naphthyridines). The compounds were screened for in vitro inhibitory activity against IGF-1R, and several compounds with improved activity (3-5 muM) were identified. Furthermore, a computational docking study was performed, which identifies a fairly consistent lowest energy mode of binding for the more-active set of inhibitors in this series, while the less-active inhibitors do not adopt a consistent mode of binding.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! Read on for other articles about 461-72-3!, 1055361-35-7
