Synthesis and anticancer activity of 4-aza-daurinol derivatives

Daurinol, a natural aryl naphthalene lactone, has been reported to have antiproliferative activity against various cell lines, and has also been shown to be efficacious in an in vivo xenograft mouse model. In this study, we tried to discover a new scaffold that enables both rapid structure-activity relationship study of daurinol and scalable synthesis of active compounds. 4-Aza-daurinol, a bioisosterism-based scaffold of daurinol, was designed and 17 analogues were synthesized and evaluated against five representative cancer cell lines. Among them, the 2,3-dihydrobenzo[b][1,4]dioxinyl derivative was found to be the most potent and showed similar activity and tendency as daurinol.

[bmIm]OH catalyzed coupling: Green and efficient synthesis of 2,8 dioxacyclopenta [a] inden-3-one derivatives in an aqua media

An efficient recyclable [bmIm]OH catalyzed and aqua mediated eco-compatible synthesis of biologically versatile 2,8 dioxacyclopenta [a] inden-3-one derivatives. Combination of ionic liquid and water has emerged out as a powerful synthetic tool for constructing C?C, C?S and C?O bonds. Disclosed methodology for introducing broad range of 2-iodophenols, 2-iodothiophenols and tetronic acid in basic ionic liquid with predictable high yield will catch the attention of synthetic chemists. This protocol has documented the notable advances and the applications of ionic liquid in heterocyclic synthesis. The chosen strategy illustrates important issues regarding scope, reactivity, product yield, reaction time, reuse and recyclability that will help in designing new synthetic routes for other heterocyclic synthesis.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Recommanded Product: Furan-2,4(3H,5H)-dione, you can also check out more blogs about4971-56-6

Multiclass method for pesticides quantification in honey by means of modified QuEChERS and UHPLC-MS/MS

Bee products can be produced in an environment contaminated by pesticides that can be transported by honey bees to the hive and incorporated into the honey. Therefore, rapid and modern methods to determine pesticide residues in honey samples are essential to guarantee consumers’ health. In this study, a simple multiresidue method for the quantification of 116 pesticides in honey is proposed. It involves the use of a modified QuEChERS procedure followed by UHPLC-MS/MS analysis. The method was validated according to the European Union SANCO/12571/2013 guidelines. Acceptable values were obtained for the following parameters: linearity, limit of detection (0.005 mg/kg) and limit of quantification (0.010 and 0.025 mg/kg), trueness (for the four tested levels the recovery assays values were between 70 and 120%), intermediate precision (RSD < 20.0%) and measurement uncertainty tests (<50.0%). The validated method was applied for determination of 100 honey samples from five states of Brazil.

Ionic liquid promoted eco-friendly and efficient synthesis of six-membered N-polyheterocycles

Background: The synthesis of N-polyheterocycles by environmentally benign method is highly attractive but challenging proposition. New strategies have been developed for the preparation of polycyclic heterocycles in the last decades. In this review article, the synthesis of nitrogen containing six-membered polycyclic heterocyclic compounds is presented with the application of ionic liquids. This contribution focuses on the literature related to the total synthesis of six-membered N-polyheterocycles. Objective: Ionic liquids not only acted as environmentally benign reaction media but also as catalysts which afforded the very promising replacements of traditional molecular solvents in organic chemistry due to their stability, non-flammability, non-volatility and ease of recyclability. Ionic liquids are utilized in metal catalyzed reactions in place of organic solvents in the last years. It has attracted considerable attention in recent years. Ionic liquids acted as alternatives of organic solvents and these ILs are environment friendly. Conclusion: In the area of green chemistry ionic liquid assisted synthesis is a very promising technique which afforded a flexible platform for the formation of heterocycles. The influence of ILs on the development of efficient and new synthetic protocols over the last decade for the construction of N-polyheterocycles is featured in this review article. These synthetic strategies will continue to attract more attention and will find a wide range of applications in organic synthesis. In conclusion, ionic liquids assisted syntheses have become an efficient and powerful tool in organic chemistry quickly.

Synthesis and Antifungal Activity of Novel Furan-2,4-dione Derivatives Containing Substituted Phenylhydrazine Moiety

A series of novel 3-(2-(substituted phenyl)hydrazinylmethylidene)furan-2,4(3H,5H)-diones were designed and synthesized with ethyl 4-chloroacetoacetate as the starting material. Their structures were confirmed by FT-IR, 1H NMR, 13C NMR, EI-MS and elemental analysis. Bioassay data demonstrated that these compounds exhibited remarkable antifungal activity against Fusarium graminearum, Botrytis cinerea, Rhizoctonia cerealis and Colletotrichum capsici. Compound 3-(2-(4-bromophenyl)hydrazinylmethylidene)furan-2,4(3H,5H)-dione (5g) had excellent bioactivity against Botrytis cinerea with an EC50 value of 0.18 mug/mL – markedly lower than the 0.24 mug/mL of the commercial fungicide procymidone. The result revealed that introducing the halogenated phenylhydrazine at the 3-position of furan-2,4(3H, 5H)-dione was an effective way to design new tetronic acid derivatives as new fungicides. A series of novel furan-2,4-dione derivatives containing a substituted phenylhydrazine moiety were designed and synthesized. These compounds exhibited remarkable antifungal activity against Fusarium graminearum, Botrytis cinerea, Rhizoctonia cerealis and Colletotrichum capsici. Compound 5g showed significantly better bioactivity than the control fungicides.
