Facile synthesis of 5-arylidene rhodanine derivatives using Na2SO3 as an eco-friendly catalyst. Access to 2-mercapto-3-aryl-acrylic acids and a benzoxaborole derivative

A simple, efficient and environment-friendly procedure for the synthesis of 5-arylidene rhodanines derivatives via a Knoevenagel type reaction was developed using rhodanine, a variety of differently substituted aldehydes and Na2SO3 a

Introducing broadened antibacterial activity to rhodanine derivatives targeting enoyl-acyl carrier protein reductase

Broadened antibacterial activity was introduced to rhodanine derivatives targeting Mycobacterial tuberculosis enoyl-acyl carrier protein reductase (Mtb InhA) by recruiting feature of xacins to bring DNA Gyrase B inhibitory capability. This is significant for preventing further bacterial injections in the tuberculosis treatment. The most potent compound Cy14 suggested comparable bioactivity (IC50=3.18μM for Mtb InhA; IC50=10nM for DNA Gyrase B) with positive controls. Structure–activity relationship discussion and molecular docking model revealed the significance of rhodanine moiety and derived methoxyl on meta-position, pointing out orientations for future modification.

Solid acid TS-1 catalyst: an efficient catalyst in Knoevenagel condensation for the synthesis of 5-arylidene-2,4-thiazolidinediones/Rhodanines in aqueous medium

Abstract: TS-1 zeolite was prepared for the synthesis of 5-arylidene-2,4-thiazolidinediones/Rhodanines in aqueous medium by incorporating titanium(IV) cations in a silicate-1 framework using hydrothermal treatment and characterized by using XRD, EDX, BET, FT-IR and SEM techniques. The catalytic activity of the catalyst was tested for Knoevenagel condensation reaction. The condensation of active ethylene 2,4-thiazolidinedione with substituted aryl aldehydes under aqueous medium at 90?°C afforded the corresponding product in excellent yield up to 92% within 30?min. The present method offers several advantages over the reported methods such as easy separation of catalyst, simple work-up procedure, and an excellent yield of desired product. Furthermore, the catalyst could be reused without significant loss in activity. Graphical abstract: [Figure not available: see fulltext.]

New spiro-oxindole constructed with pyrrolidine/thioxothiazolidin-4-one derivatives: Regioselective synthesis, X-ray crystal structures, Hirshfeld surface analysis, DFT, docking and antimicrobial studies

In this work, polycyclic heterocycles containing spirooxindole, pyrrolidine, and thioxothiazolidin-4-one rings have been synthesized via the regioselective 1,3-dipolar cycloaddition of azomethine ylide, which is generated in situ by the condensation of th

[Et3NH][HSO4] catalyzed efficient synthesis of 5-arylidene-rhodanine conjugates and their antitubercular activity

Abstract: We have described a highly efficient, safer protocol for the synthesis of 5-arylidene-rhodanine conjugates catalyzed by Bronsted acidic ionic liquid [Et3NH][HSO4] in excellent yields. The protocol offers cost-effective, environmentally benign, solvent-free conditions and recycle–reuse of the catalyst. The synthesized 5-arylidene-rhodanine conjugates were characterized on the basis of 1H NMR, 13C NMR and HRMS spectral data. A series of 5-arylidene-rhodanine derivatives 3a–h, 4a–h were synthesized and evaluated for their in vitro antitubercular activity against dormant Mycobacterium tuberculosis H37Ra and M. bovis BCG strains. Moreover, compounds 3a, 3b, 3e, 3f, 3g, 3h and 4f exhibited good antitubercular activity and were also evaluated for anti-proliferative activity against MCF-7, A549 and HCT116 cell lines using modified MTT assay and found to be noncytotoxic. Compounds 3a–h and 4f were further screened for their antibacterial activity against four bacteria strains to assess their selectivity towards M. tuberculosis. Furthermore, in silico ADME prediction of all the tested compounds followed the criteria for orally active drug and, therefore, these compounds may have a good potential for eventual development as oral agents.

Privileged scaffolds or promiscuous binders: A comparative study on rhodanines and related heterocycles in medicinal chemistry

Rhodanines and related five-membered heterocycles with multiple heteroatoms have recently gained a reputation of being unselective compounds that appear as "frequent hitters" in screening campaigns and therefore have little value in drug discovery. However, this judgment appears to be based mostly on anecdotal evidence. Having identified various rhodanines and related compounds in screening campaigns, we decided to perform a systematic study on their promiscuity. An amount of 163 rhodanines, hydantoins, thiohydantoins, and thiazolidinediones were synthesized and tested against several targets. The compounds were also characterized with respect to aggregation and electrophilic reactivity, and the binding modes of rhodanines and related compounds in published X-ray cocrystal structures were analyzed. The results indicate that the exocyclic, double bonded sulfur atom in rhodanines and thiohydantoins, in addition to other structural features, offers a particularly high density of interaction sites for polar interactions and hydrogen bonds. This causes a promiscuous behavior at concentrations in the "screening range" but should not be regarded as a general knockout criterion that excludes such screening hits from further development. It is suggested that special criteria for target affinity and selectivity are applied to these classes of compounds and that their exceptional and potentially valuable biomolecular binding properties are consequently exploited in a useful way.
