New discoveries in chemical research and development in 2021.

Glioblastoma multiforme (GBM) is the worst form of primary brain tumor, which has a high rate of infiltration and resistance to radiation and chemotherapy, resulting in poor prognosis for patients. Recent studies show that thiazolidinones have a wide range of pharmacological properties including antimicrobial, anti-inflammatory, anti-oxidant and anti-tumor. Here, we investigate the effect antiglioma in vitro of a panel of sixteen synthetic 2-aryl-3-((piperidin-1-yl)ethyl)thiazolidin-4-ones where 13 of these decreased the viability of glioma cells 30?65% (100 muM) compared with controls. The most promising compounds such as 4d, 4l, 4m and 4p promoted glioma reduction of viability greater than 50%, were further tested at lower concentrations (12.5, 25, 50 and 100 muM). Also, the data showed that the compounds 4d, 4l, 4m and 4p induced cell death primarily through necrosis and late apoptosis mechanisms. Interestingly, none of these 2-aryl-3-((piperidin-1-yl)ethyl)thiazolidin-4-ones were cytotoxic for primary astrocytes, which were used as a non-transformed cell model, indicating selectivity. Our results also show that the treatment with sub-therapeutic doses of 2-aryl-3-((piperidin-1-yl)ethyl)thiazolidin-4-ones (4d, 4l and 4p) reduced in vivo glioma growth as well as malignant characteristics of implanted tumors such as intratumoral hemorrhage and peripheral pseudopalisading. Importantly, 2-aryl-3-((piperidin-1-yl)ethyl)thiazolidin-4-ones treatment did not induce mortality or peripheral damage to animals. Finally, 2-aryl-3-((piperidin-1-yl)ethyl)thiazolidin-4-ones also changed the nitric oxide metabolism which may be associated with reduced growth and malignity characteristics of gliomas. These data indicates for the first time the therapeutic potential of synthetic 2-aryl-3-((piperidin-1-yl)ethyl)thiazolidin-4-ones to GBM treatment.

Herein we report the design, synthesis, molecular docking study and evaluation of antimicrobial activity of ten new dithioloquinolinethiones. The structures of compounds were confirmed by 1H NMR, 13C NMR and HPLC-HRMS. Before evaluation of their possible antimicrobial activity prediction of toxicity was performed. All compounds showed antibacterial activity against eight Gram positive and Gram negative bacterial species. All compounds appeared to be more active than ampicillin and almost all than streptomycin. The best antibacterial activity was observed for compound 8c 4,4,8-trimethyl-5-{[(4-phenyl-5-thioxo-4,5-dihydro-1,3,4-thiadiazol-2-yl)thio]acetyl}-4,5-dihydro-1H-[1,2]dithiolo[3,4c]quino lone-1-thione). The most sensitive bacterium En.cloacae followed by S. aureus, while L.monocytogenes was the most resistant. All compounds were tested for antifungal activity also against eight fungal species. The best activity was expressed by compound 8d (5-[(4,5-Dihydro-1,3-thiazol-2-ylthio)acetyl]-4,4-dimethyl-4,5-dihydro-1H-[1,2]dithiolo[3,4-c]quinoline-1-thione). The most sensitive fungal was T. viride, while P. verrucosum var. cyclopium was the most resistant one. All compounds were more potent as antifungal agent than reference compound bifonazole and ketoconazole. The docking studies indicated a probable involvement of E. coli DNA GyrB inhibition in the anti-bacterial mechanism, while CYP51ca inhibition is probably responsible for antifungal activity of tested compounds. It is interesting to mention that docking results coincides with experimental.

Research speed reading in 2021. Recommanded Product: Thiazolidin-2-one, Catalysts allow a reaction to proceed via a pathway that has a lower activation energy than the uncatalyzed reaction. In a document type is Article, and a compound is mentioned, 2682-49-7, Thiazolidin-2-one, introducing its new discovery.

Eight novel bioactive azo dyes containing thiazolidinone (TZD) derivatives (1O-4S) were designed and synthesized for antibacterial assays and colorimetric sensing of anions. Synthesized compounds were evaluated for their antibacterial activities using the disc diffusion technique. Majority of the compounds showed potent antibacterial activities against the tested bacterial strains in the zone assay. Moderate antibacterial activities were also exhibited in the minimum inhibitory concentration (MIC) assay. In addition, the synthesized compounds were evaluated for their colorimetric sensing of anions. In contrast to dyes with electron donating groups (EDGs), 4O having electron withdrawing groups (EWGs) showed highly selective colorimetric sensing of CN- ions. Binding interaction of 4O with CN- ions provides a remarkable colorimetric response from yellow to blue (Deltalambda = 186 nm), enabling naked-eye sensing without any spectroscopic instrumentation. Furthermore, the limit of detection (LOD) for 4O towards CN- was found to be 0.74 muM.

Background: Heterocyclic compounds have received much attention due to their versatile applications in the field of medicinal chemistry as well as organic chemistry. Objective: The main objective of this review is to give an overview of the recent application of beta-cyclodextrin catalyzed one?pot multicomponent reactions for the synthesis of different assemblies of heterocycles. Method: In this review, we have summarized the one-pot multicomponent approach towards the synthesis of heterocyclic compounds by using beta-cyclodextrin as a supramolecular catalyst. It is outlined under the headings (1) five-membered heterocyclic compounds and (2) six and seven membered heterocyclic compounds. Conclusion: This review outlined the recent key developments in the synthesis of different O-, N-and S-containing heterocyclic scaffolds, following MCRs published by using beta-CD and its derivatives as a supramolecular catalyst for the synthesis of five, six and seven membered heterocycles. The versatility of cyclodextrins and modified cyclodextrins will encourage chemists to develop new heterocyclic molecules by using multicomponent reactions in the near future.
