Acyl ureas are a well-known class of organic compounds that have drawn a lot of attention recently because of their array of chemical properties and possible multi-use in medicine. The article summarizes the synthetic procedures used to produce various Acyl urea synthons and includes instances of clinical trials, patents, and commercialized medications having Acyl urea and N-acyl urea moiety. This extensive study examines and summarizes research on acyl urea derivatives conducted over the last 20 years from a variety of sources, including PubMed, Google Scholar, and Google Websites. When it comes to the discovery of new chemicals, urea derivatives still require attention compared to other acyl compounds. This review paper aims to provide a comprehensive overview of the various synthetic approaches utilized in the design of an array of acyl ureas to accomplish the same goal. This work summarizes information related to several heteroatom-fused acyl urea compounds, which fortunately will be a very useful resource for chemists and scientists who are interested in acyl urea synthesis and its applications in chemistry.

In this study, a series of novel pyrazole-based compounds were synthesized starting from the precursor ethyl 3-(4-amino-1-phenyl-3-((4-sulfamoylphenyl)carbamoyl)-1H-pyrazol-5-yl)-3-oxopropanoate (2). Various synthetic routes were used to obtain pyrazolyl-pyrazolone 3, tricyclic dipyrazolopyridine 4a-c, thiazolylbipyrazoles 5 & 6, pyrazolo[4,3-b]pyridines 7 & 9, and tricyclic pyranopyrazolopyridine 10a–c. These compounds were screened for their antibacterial activity against four bacterial strains. The promising candidates 4a, 4b, 4c, 7, 9, and 10c exhibited minimum inhibitory concentrations ranging from 0.98 to 31.25 μg/mL. The in silico ADME properties for the active compounds exhibited similar physiochemical properties, with compound 9 demonstrating the best likeness and no inhibition effect on the popular drug metabolism enzyme CYP. Molecular docking simulations highlighted compounds 9 and 10c as potent antibacterial agents via DNA-gyrase inhibition

Nitrogen-positioned radicals are chemical entities that have a lengthier history than carbon ones and their high reactivity makes them invaluable. But, despite its power, much of its chemistry is still uncharted. Currently, developed methodologies to access nitrogen-positioned radicals, such as transition metal catalysis or visible-light photoredox methods through a single-electron transfer process, avoiding the use of harmful or toxic reagents, excess raw materials, solvents as well as pre-functionalization steps or extensive synthetic routes are in continuous progress. This revision aims to depict the recent advances in the field of iminylradicals’ syntheses, a special class of radicals placed on nitrogen, catalyzed by transition metals or photoredox techniques for the construction of C-N bonds and their synthetic applications. This work serves as a comprehensive guide for the scope of synthetic applications that this kind of radicals could have.

This review covers photoreduction reactions using xanthenes reported from 2011 to date and compares them with the conventional photocatalytic method. Xanthenes have strong absorption in the visible light spectrum (520-550nm), and their redox potential resembles organometallic complexes, such as those containing Ir or Ru, and they are also easy to handle and accessible. In addition to being metal-free, photocatalysis with xanthenes is performed under mild reaction conditions. For instance, no radical initiators are needed because the energy sources are led devices or household lamps, most reactions are performed at room temperature in common solvents (MeOH, MeCN, acetone, DMSO), and an anhydrous or inert atmosphere is usually not required. As a result, xanthene dyes hold the promise of a more environmentally friendly synthesis of organic compounds.

In terms of fused heterocyclic compounds, pyrrolopyrimidines, and their substituted analogs are among the most extensively explored scaffolds. Based on the location of the nitrogen atom in the pyrrole ring, pyrrolopyrimidines have different isomers. This study deals only with the pyrrolo[2,3-d]pyrimidine isomer. Several techniques are represented and discussed in this review for producing pyrrolo[2,3-d]pyrimidine derivatives. The first one is the cyclization of the pyrimidine ring on the pyrrole ring through the reaction of β- enaminonitrile, β-enaminoester or β-enaminoamide of the pyrrole ring with different bifunctional reagents such as formic acid, acetic acid, acetic anhydride, formamide, isothiocyanate, urea, thiourea, and carbon disulfide. The second technique includes cyclization of the pyrrole ring on the pyrimidine ring via the treatment of pyrimidine, amino-pyrimidine, diamino-pyrimidine, or triamino-pyrimidine with different reagents such as nitroalkenes, alkynes, aldehydes, and acid chlorides. In addition, different reaction methodologies like one pot, two-step, and three-step synthetic methodologies were reported. The last technique for producing pyrrolo[2,3- d]pyrimidine derivatives is through miscellaneous reactions. This review also includes the interactions of pyrrolo[ 2,3-d]pyrimidines at different active centers of the pyrrole ring with different reagents to form Nalkylated, N-glycosylated, C-5, and C-6 adducts. Besides, the interactions on the pyrimidine ring to form chloro, hydrazino, and amino-imino derivatives were also discussed. The amino-imino derivatives are key intermediates for the preparation of tricyclic pyrrolotriazolopyrimidines. Finally, the pharmaceutical and biological properties of some pyrrolo[2,3-d]pyrimidine derivatives have also been mentioned. This information can be utilized to design novel diverse pyrrolopyrimidine derivatives for recent challenges in pharmaceutical and medical studies to develop the already existing drugs or discover new ones.

:: Three compounds from Andrographis paniculata (Burm. f) Nees leaf were isolated and identified using 1H, 13C, 2D-NMR, and HR-MS techniques for the first time. Compound 3,19-Di-Oacetylandrographolide (3,19-DAA) or (4) is produced by acetylating compound (2). Compounds (2) and (4) have been investigated for their cytotoxic effects on three human cancer cell lines (SK-LU-1, Hela, and HepG2) using the MTT method. Compound (4) demonstrated significant cytotoxicity against all three cancer cell lines, with IC50 values ranging from 8.38 to 10.15 μM. This represents an increase in cytotoxicity of 2.67 to 3.12-fold compared to compound (2). One way to deal with the problem of low water solubility is by encapsulating (4) into liposomes using a thin-film hydration technique. The optimal conditions for maximizing encapsulation efficiency involve molar ratios of phosphatidylcholine, 3,19-DAA, and cholesterol at 4:1:1. Encapsulating compound (4) within nanoscale liposomes increases its water solubility compared to the free form of compound (4). Pose 324 of compound (4) demonstrated the best conformation among 500 docking conformations when docked to enzyme 1T8I in a silico docking study. The free Gibbs energy and inhibition constant were determined to be -7.09 Kcal/mol and 6.32 μM, respectively. These values help elucidate the strong interaction between compound (4) and the enzyme in the ligand interaction model. The molecular dynamics simulation using Desmond software in the Linux environment was conducted for a duration of 0 to 100 nanoseconds on the complex formed by pose 324 and 1T8I. The results showed effective interactions within the complex, with stability observed from 0 to 60 nanoseconds. Throughout the simulation, specific amino acids such as Ala 499 (involved in 90% of the simulation time with hydrogen bonding via a water bridge) and Thr 501 (involved in 50% of the simulation time with one hydrogen bond via a water bridge) were found to play significant roles. The majority of torsion bondings are C-O bondings in the acetyl group of compound (4), with torsion energy values of 13.47 Kcal/mol. Carbon atom C-29 at position 324 exhibits the highest fluctuation.

As natural capping reagents, flaxseed gel, caprylic/capric triglyceride, aloe vera, and propylene glycol were utilized in the synthesis of ZnO-NPs in the current study. The synthesized ZnO NPs structure was characterized by Transmission Electron Microscopy (TEM), Fourier Transform Infrared (FT-IR), and X-Ray Diffraction (XRD). The prepared ZnO-NPs were used as an efficient catalyst for the production of a new series of fused polynuclear heterocyclic system-based imidazoquinazoline by multicomponent reaction. The reaction was initiated by mixing 2-aminobenzimidazole, aryl/hetaryl aldehydes, and betanaphthol under solvent-free conditions at 60-70 °C in the presence of a catalytic amount of the synthesized ZnO-NPs. As demonstrated by molecular docking, the prepared ligands (4, 7, 8, 9, and 11) exhibited outstanding validation as aurora kinase inhibitors in comparison to AKI-001, the prototype pentacyclic inhibitor. synthesis of some new imidazo[2,1-b]quinazoline derivatives by green method with docking validation as aurora kinase (AKI-001) inhibitor no

Flow assurance encompasses the technical challenges of transporting hydrocarbon mixtures from the reservoir to the platform and refineries. Challenges in flow assurance include gas hydrate plugs, deposition of paraffin wax, asphaltenes, naphthenates, scale, and corrosion. Managing these deposits incurs high costs due to production interruptions and remediation operations like pigging, solvent injection, acid dissolutions, and thermal treatments. Therefore, prevention methods, such as the use of chemicals that inhibit deposit formation, are preferred. This review consolidates scientific works highlighting the role of carboxylic acids in the synthesis of chemicals for addressing flow assurance challenges as starting materials or final products for direct use. These organic compounds are already employed for the mild remediation of scale and naphthenate deposits and inhibiting gas hydrate, paraffin wax, asphaltene, scale deposits, and corrosion. Moreover, they play a crucial role in developing green flow assurance challenges inhibitors, given that some, like fatty acids, amino acids, and aromatic carboxylic acids, can be derived from natural sources. The presence of the carboxylic acid group in polymers and biopolymers is also essential for the effectiveness of these products as inhibitors. The literature further suggests that carboxylic acids will play a key role in the future development of simultaneous gas hydrate, corrosion, and scale inhibitors.

2-Thioxoimidazolidin-4-one derivatives 3, 4, 7, 8, and 9 have been synthesized from 3- (benzylideneamino)-2-thioxoimidazolidin-4-one (2) as a starting material. Compounds 3, 4, 7, 8, and 9 were obtained via the reaction of compound (2) with ethyl chloroacetate, methyl acrylate, and chlorophenacyl bromide, respectively. Elemental analysis and several spectroscopy techniques were used to confirm the synthesized compounds. The synthesized compounds, particularly compounds 7 and 8, exhibited significant cytotoxic influences on MCF-7 cells, surpassing staurosporine. Compounds 7 and 8 can induce apoptosis in those treated MCF-7 cells. Studying molecular docking approved that compounds 7 and 8 bind in two and three dimensions to the aromatase binding pockets. Molecular modeling indicates compounds 7 and 8 have a strong affinity for human topoisomerase II beta, establishing its promise as a multifaceted antitumor agent for breast cancer.
