Small-Molecule Screens Reveal Novel Haustorium Inhibitors in the Root Parasitic Plant Triphysaria versicolor

Root parasitic weeds in Orobanchaceae pose a tremendous threat to agriculture worldwide. We used an in vitro assay to screen libraries of small molecules for those capable of inhibiting or enhancing haustorium development in the parasitic plant Triphysaria versicolor. Several redox-modifying molecules and one structural analog of 2,6-dimethoxybenzo-quine (DMBQ) inhibited haustorium development in the presence of the haustorium-inducing factor DMBQ, some of these without apparent growth inhibition to the root. Triphysaria seedlings were able to acclimate to some of these redox inhibitors. Transcript levels of four early-stage haustorium genes were differentially influenced by inhibitors. These novel haustorium inhibitors highlight the importance of redox cycling for haustorium development and suggest the potential of controlling parasitic weeds by interrupting early-stage redox-signaling pathways.

Phosphorus-containing amino acids with a P-C bond in the side chain or a P-O, P-S or P-N bond: From synthesis to applications

Since the discovery of (l)-phosphinothricin in the year 1970, the development of alpha-amino acids bearing a phosphorus group has been of renewed interest due to their diverse applications, including their use in [18F]-fluorolabeling, as fluorescent probes, as protecting groups and in the reversible immobilization of amino acids or peptide derivatives on carbon nanomaterials. Considerable progress has also been achieved in the field of antiviral agents, through the development of phosphoramidate prodrugs, which increase significantly the intracellular delivery of nucleoside monophosphate and monophosphonate analogues. This review aims to summarize the strategies reported in the literature for the synthesis of P(iii), P(iv) and P(v) phosphorus-containing amino acids with P-C, P-O, P-S or P-N bonds in the side chains and their related applications, including their use in natural products, ligands for asymmetric catalysis, peptidomimetics, therapeutic agents, chemical reagents, markers and nanomaterials. The discussion is organized according to the position of the phosphorus atom linkage to the amino acid side chain, either in an alpha-, beta-, gamma- or delta-position or to a hydroxyl, thiol or amino group.

The reactions proceeded in a highly efficient and selective manner across a broad range of substrates demonstrating excellent functional group tolerance. In addition, this chlorination reaction can be used for the modification of N-heterocyclic scaffolds of appealing ligands and pharmaceuticals.

Benzothiazole derivatives as anticancer agents

Benzothiazole (BTA) belongs to the heterocyclic class of bicyclic compounds. BTA derivatives possesses broad spectrum biological activities such as anticancer, antioxidant, anti-inflammatory, anti-tumour, antiviral, antibacterial, anti-proliferative, anti-diabetic, anti-convulsant, analgesic, anti-tubercular, antimalarial, anti-leishmanial, anti-histaminic and anti-fungal among others. The BTA scaffolds showed a crucial role in the inhibition of the metalloenzyme carbonic anhydrase (CA). In this review an extensive literature survey over the last decade discloses the role of BTA derivatives mainly as anticancer agents. Such compounds are effective against various types of cancer cell lines through a multitude of mechanisms, some of which are poorly studied or understood. The inhibition of tumour associated CAs by BTA derivatives is on the other hand better investigated and such compounds may serve as anticancer leads for the development of agents effective against hypoxic tumours.

Synthetic heterocyclic candidates as promising alpha-glucosidase inhibitors: An overview

alpha-Glucosidase enzyme inhibition is an effective therapeutic decorum in the treatment of type 2 diabetes mellitus. Since 1990, three alpha-glucosidase inhibitors are known to exist clinically, Acarbose, Voglibose and Miglitol. Side effects and long synthetic routes to access them forced the researchers to move their focus to discover simple and small heterocyclic motifs that work as promising alpha-glucosidase inhibitors and may eventually lead to the management of postprandial hyperglycemic condition in T2DM. In this regards, this review deals with recently discovered heterocyclic molecules that have been evaluated to exhibit inhibition of alpha-glucosidase enzyme.

Recent advances in the synthetic and medicinal perspective of quinolones: A review

In the modern scenario, the quinolone scaffold has emerged as a very potent motif considering its clinical significance. Quinolones possess wide range of pharmacological activities such as anticancer, antibacterial, antifungal, antiprotozoal, antiviral, anti-inflammatory, carbonic anhydrase inhibitory and diuretic activity etc. The versatile synthetic approaches have been successfully applied and several of the resulted synthesized compounds exhibit fascinating biological activities in numerous fields. This has prompted to discover quinolone-based analogues among the researchers due to its great diversity in biological activities. In the past few years, various new, efficient and convenient synthetic approaches (including green chemistry and microwave-assisted synthesis) have been designed and developed to synthesize diverse quinolone-based scaffolds which represent a growing area of interest in academic and industry as well as to explore their biological activities. In this review, an attempt has been made by the authors to summarize (1) One of the most comprehensive listings of quinolone-based drugs or agents in the market or under various stages of clinical development; (2) Recent advances in the synthetic strategies for quinolone derivatives as well as their biological implications including insight of mechanistic studies.
