SYNTHESIS AND IN-VIVO ACTIVITY OF NOVEL ANTIHYPERTENSIVE AGENT BASED ON PYRIDAZINE SCAFFOLD

The main objective of the present research work to synthesize, characterization, and in-vivo evaluation of Pyridazine derivatives. To study the different synthesized derivatives by using different analytical parameters like IR, Mass, and NMR analysis. And also find out the antihypertensive activity. The studies on the hydralazine group drugs led to the synthesis of many Pyridazine derivatives with a wide activity spectrum on the cardiovascular system. Pyridazine derivatives, a class of compounds containing the N-N bond, exhibit a wide range of pharmacological activities such as antidepressant, antihypertensive, and cardiotonic, etc. Some 6-(substituted phenyl)-2-(substituted methyl)-4,5-dihydropyridazin-3(2H)-one derivative was synthesized by reacting 6-Phenyl substituted 2,3,4,5-Tetrahydro pyridazin-3-one with cyclic secondary amine under Mannich reaction conditions. A total of twenty compounds (vj1-vj20) were synthesized under Mannich reaction conditions. Out of twenty compounds, around six derivatives were selected for evaluation of antihypertensive activities by a non-invasive method using the Tail Cuff method. Most of the compounds showed good antihypertensive activity. Few compounds like vj3, vj6, vj9, vj14, vj19, and vj20 were found to show a highly significant reduction in mean arterial blood pressure but at a higher dose in comparison to standard drugs like propanolol and hydralazine. The substituted pyridazine derivatives discovered in this study may provide valuable therapeutic intervention for the treatment of hypertension.

Synthesis and Application of Stable Nitroxide Free Radicals Fused with Carbocycles and Heterocycles

Stable nitroxide free radicals have traditionally been associated with 2,2,6,6-tetramethylpiperidine- 1-oxyl (TEMPO) or its 4-substituted derivatives as relatively inexpensive and readily accessible compounds with limited possibilities for further chemical modification. Over the past two decades, there has been a resurgence of interest in stable free radicals with proper functionalization tuned for various applications. The objective of this review is to present recent results with synthetic methodologies to achieve stable nitroxide free radicals fused with aromatic carbocycles and heterocycles. There are two main approaches for accessing stable nitroxide free radicals fused with arenes, e.g., isoindoline-like nitroxides: further functionalization and oxidation of phthalimide or inventive functionalization of pyrroline nitroxide key compounds. The latter also offers the constructions of versatile heterocyclic scaffolds (furan, pyrrole, thiophene, 1,2-thiazole, selenophene, pyrazole, pyrimidine, pyridine, pyridazine, 1,5-benzothiazepine) that are fused with pyrroline or tetrahydropyridine nitroxide rings. The possible applications of these new stable nitroxide free radicals, such as covalent spin labels and noncovalent spin probes of proteins and nucleic acids, profluorescent probes, building blocks for construction of dual active drugs and electroactive materials, and substances for controlled free radical polymerization, are discussed.

Construction of Pyridazine Analogues via Rhodium-mediated C-H Activation

Herein a rhodium (III)-mediated catalysis was demonstrated for approaching the structurally divergent N, N-bicyclic pyridazine analogues. The pyrazolidinone moiety was used to direct the ortho C-H activation and this led to a general synthesis of benzopyridazine analogues with satisfactory yields. The crucial effect of the base was illustrated in the sequential dehydration process. For mechanistic insight, control experiments were performed for illustration of the catalytic circle. Gram scale synthesis and several practical transformations were conducted for further applications.

Pyridazine as a privileged structure: An updated review on anticancer activity of pyridazine containing bioactive molecules

Identification of potent anticancer agents with high selectivity and low toxicity remains on the way to human health. Pyridazine featuring advantageous physicochemical properties and antitumor potential usually is regarded as a central core in numerous anticancer derivatives. There are several approved pyridazine-based drugs in the market and analogues currently going through different clinical phases or registration statuses, suggesting pyridazine as a promising drug-like scaffold. The current review is intended to provide a comprehensive and updated overview of pyridazine derivatives as potential anticancer agents. In particular, we focused on their structure-activity relationship (SAR) studies, design strategies, binding modes and biological activities in the hope of offering novel insights for further rational design of more active and less toxic anticancer drugs.

Base Promoted Three-Component Annulation of 4-Diazoisochroman-3-imines with Dimethylsulfonium Ylides: Synthesis of Highly Functionalized Isochromeno[4,3-c]pyridazines

A novel method has been developed to synthesize a unique class of highly functionalized isochromeno[4,3c]-pyridazines. This reaction features an intermolecular functionalization of terminal nitrogen atom of diazo group of 4-diazoisochoman-3-imine with two dimethylsulfonium ylide components, followed by a base promoted 6-exo-trig cyclization step. Readily available starting materials, a broad substrate scope, and operationally simple, mild, and catalyst-free reaction conditions are the prominent features of this method.

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. you can also check out more blogs about 2605-67-6. SDS of cas: 2605-67-6.

Synthesis and evaluation of analgesic, behavioral effects and chronic toxicity of the new 3,5-diaminopyrazole and its precursor the thiocyanoacetamide

A This study aimed to explore the analgesic, antioxidant, behavioral and toxicological effects of 3,5-diaminopyrazole and thiocyanoacetamide. Caffeine was used as reference drug whose effects are known after oral treatment with an efficient dose (10 mg/kg/day) for 30 days. The preliminary bioassays indicated that both compounds at this dose have strong antioxidant capacities and present highly analgesic effects. The behavioral study showed an activation of the rat memory by thiocyanoacetamide. This molecule caused a phobia state to open areas in the elevated plus maze and specifically agoraphobia in the open field with a lack in the development of the exploratory capacity. 3,5-Diaminopyrazole caused memory troubles in rats that forgot the pathway to the exit from the maze, and induced an anxiety state revealed by immobility in closed arms of the elevated plus maze. All these observations were compared to the treatment by the known analgesic, caffeine, which increased the state of vigilance of the rats and developed their exploratory capacity. The chronic treatment with the investigated compounds showed no sign of toxicity with the absence of effect on the body and organ weights, blood count, kidney and liver function and histology. 3,5-Diaminopyrazole and thiocyanoacetamide have potent antioxidant and analgesic activities that are higher than caffeine with a safety profile. The chronic treatment by thiocyanoacetamide activated the memory and caused an emotional state of agoraphobia, but 3,5-diaminopyrazole caused a memory impairment and an emotional state of anxiety. Thus, the present study warrants further investigations involving these novel molecules for a possible development of new strong analgesic and antioxidant drugs which have an effect on the memory capacity.

Determination of the Radical Reactivity Ratios of 2-(N-Ethylperfluorooctanesulfonamido)ethyl Acrylate and Methacrylate in Copolymerizations with N,N-Dimethylacrylamide by in Situ H-1 NMR Analysis As Established for Styrene-Methyl Methacrylate Copolymerizations

A model system of styrene (St) and methyl methacrylate (MMA) was copolymerized in an NMR tube at 60 degrees C using 2,2′-azobis(isobutyronitrile) as the initiator and pyridazine as an internal standard to optimize an in situ( 1)H NMR spectroscopic method for determining reactivity ratios by generating data at hundreds of instantaneous comonomer compositions (244 data points from 8 to 91 mol % St) starting with only nine initial comonomer compositions. The radical reactivity ratios of styrene (r(st) = 0.697 +/- 0.010) and methyl methacrylate (r(MMA) = 0.491 +/- 0.007) were determined by nonlinear least-squares fitting of a Mayo-Lewis plot of the instantaneous copolymer composition as a function of the comonomer feed composition using the terminal model and MINITAB statistical software, in which the copolymer composition was calculated by assuming that all comonomer consumed was converted to copolymer without side reactions; the results were similar to accepted literature values for the terminal and implicit penultimate models. After correcting for changes in the lock value at the initial stages of the copolymerization (because of solids formed in the sealed NMR tube), the same technique was used to determine the reactivity ratios of 2-(N-ethylperfluorooctanesulfonamido)ethyl acrylate (FOSA; r(FOSA) = 1.624 +/- 0.048) and 2-(N-ethylperfluoro-octanesulfonamido)ethyl methacrylate (FOSM; r(FOSM) = 2.876 +/- 0.083) in their radical copolymerizations with N,N-dimethylacrylamide (DMA; r(DMA) = 1.126 +/- 0.031 with FOSA; r(DMA) = 0.859 +/- 0.026 with FOSM).

Design and Synthesis of Pyridazine Containing Compounds with Promising Anticancer Activity

Certain pyridazine containing compounds 2a-f, 3a, b, 4a, b, 5a, b, 6a and b were synthesized and characterized by spectroscopic means and elemental analysis. All the synthesized compounds were screened for their cytotoxic activity in vitro on colon cancer cell line (HCT-116) and breast cancer cell line (MCF-7). In addition, the antitumor activity of the synthesized compounds was tested in vivo against Ehrlich’s ascites carcinoma (EAC) solid tumor grown in mice. The in vitro vascular endothelial growth factor receptor (VEGFR) enzyme inhibition assay was carried out for the most active compounds at a single dose of 10 mu m. The obtained results revealed that compound 5b, which showed potent cytotoxic activity against HCT-116 also, exhibited the highest inhibition in the VEGFR kinase assay (92.2%).
