SYNTHESIS, CHARACTERIZATION AND PHARMACOLOGICAL EVALUATION OF SOME ARYL PIPERAZINE COMPOUNDS

In this planed research work, aryl piperazine derivatives will be synthesized because aryl piperazine currently the most important constructive block in drug discovery with positive pharmacological evaluation. A series N- (4-(benzo[d]thiazol-2-yl) phenyl)-2-[4-(arylsubstituted) piperazines-1-yllacetamide, N-(4-(benzo[d]oxazol-2-yl)phenyl)2-[4-(arylsubstituted)piperazines-1-yl]acetamide and Synthesis of N-(4(benzo[d]imidazol-2-yl) phenyl)- 2- (4-(arylsubstituted)piperazin-1-yl) acetamide will be synthesized with their characterization such as melting point determination, Thin-layer chromatography (TLC) and spectral analysis. After that, pharmacological evaluation, such as antibacterial activity, will be performed for synthesized compounds. All the synthesized compounds were reported for determination of zone of inhibition (mm), minimum inhibitory concentrations (MIC) were also calculated for effective derivatives, with an objective to offer some potent antimicrobial agents to human beings. Antimicrobial activity is determined based on their in-vitro activity in pure cultures. In-vitro susceptibility testing is done by two methods i.e.. Turbidimetric/photometric/tube dilution method and agar diffusion/cupplat/cylinder plate method.

PIP/TMC Interfacial Polymerization with Electrospray: Novel Loose Nanofiltration Membrane for Dye Wastewater Treatment

A loose nanofiltration (NF) membrane with excellent dye rejection and high permeation of inorganic salt is required to fractionate dye/salt mixture in dye wastewater treatment. In this study, we fabricated the loose NF membrane by using the electrospray interfacial polymerization (EIP) method. It is a novel and facile interfacial polymerization method, which controls the thickness of the poly(piperazine-amide) (PPA) layer in nanometers (1 nm/min) and changes cross-linking degree of PPA layer and pore size by varying the electrospray time; consequently, water permeance and dye/salt rejection ratio can be handled. The fabricated EIP membrane with an optimized fabrication condition (M30, electrospray time was 30 min) possessed excellent pure water permeance (20.2 LMH/bar), high dye rejection (e.g., 99.6% for congo red (CR)), and low salt rejection (e.g., 6.3% for NaCl). Moreover, the EIP membrane exhibited enhanced antifouling property than commercial NF membrane (NF90) with a high flux recovery rate (FRR) of 87.1% and low irreversible fouling (R-ir) of 12.9% after fouled by bovine serum albumin (BSA) due to its great smooth surface (average roughness (R-a) is 12.2 nm), hydrophilicity property, enhanced zeta potential, and low protein adsorption. The results indicate that the EIP loose NF membrane had a high potential for dye wastewater treatment.

1H,4H-Piperazine-diium Dichlorosulfonate: Structure Elucidation and its Dual Solvent-Catalyst Activity for the Synthesis of New Dihydro-[1,2,4]triazolo[1,5-a]pyrimidine Scaffolds

A new ionic liquid containing a 1H,4H-piperazine-diium ring and chlorosulfonate as a 1,4-dicationic core and counter ion, respectively, was designed and synthesised. The structure elucidation of this ionic liquid was conducted by 1D and 2D NMR, FT-IR, Raman, and mass spectrum analysis. The physical properties of this ionic liquid were determined and reported. Furthermore, the dual solvent-catalyst activity of piperazine-1,4-diium dichlorosulfonate was investigated for the synthesis of new dihydro[1,2,4]triazolo[1,5-a]pyrimidines through a one-pot three-component reaction.

Solubility and Permeability Improvement of Allopurinol by Cocrystallization

Allopurinol is a xanthine oxidase inhibitor with poor solubility and permeability, which severely limit its drug absorption following the administration of some dosage forms, such as tablets and rectal suppositories. To improve the physicochemical properties, three cocrystals of allopurinol with isonicotinamide (ALP-INA), piperazine (ALP-PIP), and 2,4-dihydroxybenzoic acid (ALP-24DHBZA) were successfully prepared by a slurry or liquid-assisted grinding method. The obtained cocrystal materials were characterized by single-crystal X-ray diffraction, powder X-ray diffraction, infrared spectroscopy, differential scanning calorimetry, and thermogravimetric analyses and were subjected to dynamic vapor sorption, dissolution, and membrane permeability studies. ALP-INA showed solubility and diffusion/membrane permeability similar to those of the parent drug. In contrast, ALP-PIP exhibited improved diffusion/membrane permeability, and ALP-24DHBZA exhibited improved dissolution behavior, respectively. These results suggest that ALP-PIP and ALP-24DHBZA have the potential to be developed as new, more efficient formulations of allopurinol.

A new four-components post-Ugi transformation process has been studied. It provides an efficient access to biologically active piperazine-2,5-dione derivatives in high yield. The framework of piperazine-2,5-dione derivatives has been constructed by a tandem-decarboxylation of alpha-keto carboxylic acids promoted by a green catalyst trimethylsilyl trifluoromethane sulfonate (TMSOTf). Molecular docking study of piperazine-2,5-dione derivatives has been performed with various anticancer target proteins: human androgen receptor (AR) (PDB ID: 1E3G), human steroidogenic cytochrome P450 17A1 (PDB ID: 4NKV), epidermal growth factor receptor 2 HER2 (PDB ID: 3PP0), and estrogen receptor alpha (ER alpha) (PDB ID: 1A52), and has indicated their possible efficient interactions via hydrogen bonds.

Synergistic flame retardant effect of piperazine salt and ammonium polyphosphate as intumescent flame retardant system for polypropylene

Amino trimethylene phosphonic acid piperazine (ATPIP)salt, as a novel charring agent, is prepared via a simple ionic reaction in distilled water using amino trimethylene phosphate (ATMP) and piperazine as raw materials. The synergistic flame retardant effect of ATPIP and ammonium polyphosphate (APP) as an intumescent flame retardant (IFR) is investigated by various characterization and testing methods. The results show that the polypropylene (PP)/modified APP with piperazine (MAPP)/ATPIP ternary blend passes UL-94 V-0 rating and achieve a limiting oxygen index (LOI) of 30% at a loading level of 25 wt% IFR (MAPP:ATPIP = 3:1). Meanwhile, the total smoke production (TSP) value of IFR-PP samples is 3.3 m(2), which decreases by 93.2% compared with that of pure PP, exhibiting excellent smoke suppression performance. Besides, the analysis of gaseous pyrolysis products and char residue indicates that the IFR-PP samples show a synergistic flame-retardant mechanism including the gas phase and the condensed phase.

Synthetic Route of 841-77-0, Consequently, the presence of a catalyst will permit a system to reach equilibrium more quickly, but it has no effect on the position of the equilibrium as reflected in the value of its equilibrium constant.I hope my blog about 841-77-0 is helpful to your research.
