Schiff bases(Ketimines) were prepared from Methyl-1-naphthyl-ketone with 2-Hydroxy-aniline, 3-Hydroxyaniline, 4-Hydroxy-aniline, 3-Nitroanilines and 4-Bromo-aniline using toluene as solvent by azeotropic(reflux) method using Dean and Stark. The synthesized ketimines were characterized by colour, physical constants, TLC and FTIR spectra. The purity of the synthesized compounds was confirmed from the information gathered from TLC, elemental and FTIR spectral analysis.

The clinical success of a compound is often curtailed because of inadequate safety, pharmacokinetics or efficacy. Human tissue can be used to identify the potential shortcomings of new drugs before they undergo testing in man. This review highlights the consent and ethical approval required for the use of human tissues and discusses their use for predicting human ADME and safety profiles of drugs in preclinical development. The ability to retrieve a wide range of viable tissues from human donors provides the opportunity to test drugs for many potential use-limiting side-effects.

Rhodanines are accepted as advantaged heterocycles in medicinal chemistry as one of the 4-thiazolidinones subtypes. The aim of this paper is to analyze the features of rhodanine and its application in pharmacy and medicine. Some of the properties of rhodanine such as antiviral, anticancer, antimicrobial, and drug discovery have recently been reported. Although there are still vague points in the structure and mechanism of polymerization of this substance, there is a significant increase in the use of rhodanine in medicine. In this review paper, it can be said that we have provided a general overview of the recent advances in the rhodanine-based material which its application is more in the field of drug discovery and anticancer activity. The review starts with a summary of the antiviral activity of rhodanine-based materials and nanocomposites in general. Then in the next step, the detailed description is followed on their applications in the fields of anticancer activity, drug discovery, and an innovative type of rhodanine (RH) and thiohydantoin (TH) derivatives were created and combined in order to recognize tau pathology in the brains of patients with Alzheimer?s disease (AD). Through this review, we hope to promote rhodanine and its role in medicine and pharmacy becomes more prominent.

Abstract: A new series of spirothiazolidinone polymers has been accomplished by solution polycondensation of 4,12-dioxa-1,9-dithiadispiro[4.2.4.2]tetradecane-3,11-dione (3) with different aliphatic and aromatic diamines. A model compound 4 was prepared by the reaction of spiro-monomer 3 with benzyl amine and was characterized by elemental and spectral analyses. These polymers were characterized by elemental and spectral analyses. The thermal properties of these polymers were investigated by thermogravimetric analysis and differential thermal analysis measurements. The morphological properties of selected polymers 5c and 5e were tested using scanning electron microscope to study their surface morphology. The molar masses of polymers 5a, 5b, and 5d were determined by gel permeation chromatography. In addition, the anti-inflammatory activities were studied for these spiro-polymers in comparison with the model compound by determination in vivo using acute carrageenan-induced paw edema in rats.

A series of new 4-thiazolidinone derivatives were synthesized by reacting various coumarinyl schiff bases with thioglycollic acid. The intermediate coumarinyl schiff bases were synthesized by reacting 4-hydroxyl coumarin with various substituted anilines in alcohol medium. All the newly synthesized compounds were assigned on the basis of IR,1H NMR and mass spectral data. All the newly synthesized compounds were evaluated for in-vitro antioxidant activities like DPPH, nitric oxide and hydrogen peroxide radical scavenging assay models. Most of the synthesised compounds showed good antioxidant activity.

2-(2-Arylidenehydrazinyl) thiazol-4(5H)-ones having epidermal growth factor receptor (EGFR) inhibitory activity were subjected to quantitative structure activity relationship (QSAR) (2 and 3 dimensional) analysis and pharmacophore study in the present work. The best 2 dimensional (2D) QSAR model had r2 (squared correlation coefficient), q2 (cross validated correlation coefficient) and pred_r2 (predictive correlation coefficient) values of 0.8630, 0.7652 and 0.9533 respectively with Partial least square regression (PLSR) analysis. This model showed that count of number of nitrogen atoms separated from oxygen atom by four bonds (T_N_O_4) and Radius Of Gyration (size descriptor) descriptors contribute positively and count of number of any atoms separated from carbon atom by four bonds (T_T_C_4) contributes inversely to the biological activity. The k-nearest neighbor (kNN) method produced a significant 3 dimensional (3D) QSAR model exhibiting q2 and pred_r2 values of 0.6615 and 0.8833 respectively. PLSR gave a significant 3D QSAR model having r2, q2 and pred_r2 values of 0.8449, 0.7816 and 0.7834 respectively. Both 3D QSAR models depict the need of less bulky substituents at R2 position while PLSR 3D QSAR model also portrays the need of more bulky substituent at R4 position. The identified common pharmacophore features are one aromatic (AroC) and three hydrogen bond acceptors (HAc) obtained from Molsign and Pharmagist approaches. The present work may be useful for further lead optimization and designing of potent anticancer agents.

Electric Literature of 2682-49-7, Redox catalysis has been broadly utilized in electrochemical synthesis due to its kinetic advantages over direct electrolysis. 2682-49-7, Name is Thiazolidin-2-one, molecular formula is C3H5NOS.

Background: Microtubules act as a useful and strategic molecular target for various anticancer drugs that binds to its distinct sites in tubulin subunits and inhibits its polymerization and ultimately leads to cell death. Moreover, numerous reports highlight the cytotoxic effects of constraint Combretastatin analogs and thiazolidinone derivatives. Objective: Therefore, the present study investigates the potential of thiazolidinone constraint combretastatin analogs as tubulin inhibitors. Method: By incorporating silica supported fluroboric acid, a series of thiazolidinone constraint combretastatin analogs were synthesized in a microwave reactor under solvent free conditions. To optimize the reaction conditions, the detailed investigation was done for the catalytic influence of HBF4-SiO2. All the synthesized analogs were assessed for in-vitro cytotoxicity against THP-1, COLO-205, HCT-116 and A-549 human cancer cell lines. Top hits were further examined for their tubulin polymerization inhibition and their effect on microtubule assembly. The significant cytotoxicity and tubulin polymerization inhibition of the most potent structure was further rationalized by molecular modelling studies. Results: The results stated that CS-2, CS-3 and CS-20 possessed significant cytotoxic potential with the IC50 values ranging from 1.21 to 5.50 muM against THP-1, COLO-205, HCT-116 human cancer cell lines. Established structure activity relationship revealed that the nature of Ring A substantially influences the cytotoxic potential of the compounds. Placement of methoxy substituents on the phenyl ring (Ring A) was found to be the most preferred structural feature. Compound CS-2 was found to considerably inhibit the tubulin polymerization (IC50 value 2.12 muM) and caused disruption of microtubule assembly as demonstrated by immunoflourescence technique. In molecular modelling studies, CS-2 exhibited various hydrophobic as well as hydrogen bonding interactions at colchicine binding site and was found to be stabilized in this cavity. Conclusion: This work provides an efficient methodology for the synthesis of antitubulin thiazolodinone- combretastatin hybrids.
