In a document, author is El-Shamy, Ibrahim E., introduce the new discover, Name: 3,4-Difluoronitrobenzene.

The phthalazine carbohydrazide 2 was prepared and incorporated into the corresponding 1,2,4-triazole and carbamate derivatives. Phthalazine carboxylic acid hydrazide 2 was treated with isatine and cyclohexanone to give the corresponding hydrazone derivatives 16,19 in good yields. Furthermore, cc-amino acid derivative conjugated with 1-oxophthalazine moiety 35 was synthesized by the reaction of the corresponding aizde 28, via the azide-coupling method, with glycine methyl ester. The peptide ester 35 was converted into their corresponding amide 36 by treating with methanolic ammonia. Moreover, 35 was boiled with hydrazine hydrate to afford the corresponding hydrazide 37. Finally, the dipeptide 38 was prepared by coupling of 35 with L-alanine methyl ester. Some of these compounds were screened in vitro for their antimicrobial activity. The energy gap between the highest occupied molecular orbital and lowest unoccupied molecular orbital has been calculated using the theoretical computations to reflect the chemical reactivity and kinetic stability of compounds.

Thrombosis is a major complication that could be fatal in acute or chronic cardio-cerebral-vascular diseases. Therefore, the development of novel agents for anticlotting and the prevention of thrombosis and cardiovascular diseases are clinically significant. This study aimed to evaluate the anticoagulant and antithrombotic effects of 6-(4-chlorophenoxy)-tetrazolo[5,1-a]phthalazine (Q808), a new phthalazine tetrazole derivative. Bleeding time, clotting time, and serum calcium ion (Ca2+) concentration were assessed in mice, whereas arteriovenous thrombus weight and plasma prothrombin time were evaluated in rats, and platelets Ca2+ influx was determined in rabbit. Daily oral administration of Q808 at 25, 50, or 100 mg/kg for 3 days significantly delayed bleeding time and clotting time in mice compared with controls. Q808 administration at 50 mg/kg significantly reduced experimental thrombus weight by 62.6% and delayed plasma prothrombin time by 58.7% in rats, whereas 50 and 100 mg/kg of Q808 daily significantly increased serum Ca2+ concentration in mice. Q808 at 0.2, 0.4, and 0.8 mg/mL significantly inhibited thrombin-induced Ca2+ influx in rabbit platelets. Our results suggest that Q808 at 25-200 mg/kg daily exerts anticoagulant and antithrombotic effects, and its mechanisms of action may involve both the intrinsic and extrinsic coagulation pathways that inhibit certain coagulation factors and platelet functions.

Application In Synthesis of 4-(Methylamino)-3-nitrobenzoic acid, Reactions catalyzed within inorganic and organic materials and at electrochemical interfaces commonly occur at high coverage and in condensed media, causing turnover rates to depend strongly on interfacial structure and composition. 41263-74-5, Name is 4-(Methylamino)-3-nitrobenzoic acid, SMILES is O=C(O)C1=CC=C(NC)C([N+]([O-])=O)=C1, belongs to phthalazine compound.

A new series of 2-substituted-2,3-dihydrophthalazine-1,4-diones (2 9) were designed and synthesized to evaluate their anticonvulsant activity. The neurotoxicity was assessed using the rotarod test. Molecular docking was performed for the synthesized compounds to assess their binding affinities as -aminobutyric acid A (GABA-A) receptor agonists as a possible mechanism of their anticonvulsant action, to rationalize their anticonvulsant activity in a qualitative way. The data obtained from the molecular modeling was strongly matched with that obtained from the biological screening, which revealed that compounds 5(a), 9(b), and 9(h) showed the highest binding affinities toward the GABA-A receptor and also showed the highest anticonvulsant activities with relative potencies of 1.66, 1.63, and 1.61, respectively, compared with diazepam. The most active compounds 5(a), 9(b), and 9(h) were further tested against maximal electroshock seizures. Compounds 5(a) and 9(b) showed 100% protection at a dose level of 125 mu g/kg, while compound 9(h) exhibited 83.33% protection at the same dose level. A GABA enzymatic assay was performed for these highly active compounds to confirm the obtained results and to explain the possible mechanism for their anticonvulsant action. These agents exerted low neurotoxicity and a high safety margin compared with valproate as a reference drug. Most of our designed compounds exhibited a good ADMET profile.

The use of hydrazinecarboxamides as a new class of carbamoylating agents has been established through the dehydrazinative Minisci reaction of electron-deficient nitrogen heteroarenes. A wide range of electron-deficient nitrogen heteroarenes, including isoquinoline, quinoline, pyridine, phenanthridine, quinoxaline, and phthalazine, underwent copper/acid-catalyzed oxidative carbamoylation with hydrazinecarboxamide hydrochlorides to afford structurally diverse nitrogen-heteroaryl carboxamides as single regioisomers in moderate to excellent yields. The functional group tolerance was substantially demonstrated in the direct carbamoylation of quinine obviating multistep sequences involving protecting groups and prefunctionalization of the heterocycle.

A SO3H-bearing carbonaceous solid catalyst has been synthesized through sulfonation followed by the hydrothermal carbonization method from renewable resource polyethylene glycol. The biodegradable catalyst was characterized by XRD, TEM, FT-IR, and energy dispersive X-ray. The surface area and pore diameter of the catalyst were determined by a nitrogen adsorption-desorption isotherm experiment. A highly efficient multicomponent heteroannulation protocol for the synthesis of a library of 1H-pyrazolo[1,2-b]phthalazine-5,10-dione derivatives has been developed by applying the solid acid catalyst. This synthesis was established to follow the group-assistant-purification chemistry process avoiding traditional chromatography. The aqueous reaction medium, easy recovery of the catalyst, and high yield of the products make the protocol attractive, sustainable, and economic. This work may not only lead to environmentally benign systems, but also will provide a new aspect of organic chemistry in water.
