This research involved synthesis. novel  heterocyclic derivatives (quinazoline and thiazinone)  derivatives , this compounds prepared from starting react (4-methoxy-2-nitroaniline) with 2,4-dimethoxyacetophenone  to gate azo derivative (A) , (A) interact with aromatic amine derivatives to produce imine compounds (B1-B2), imine derivatives  interact with (anthranilic acid , 2-mercaptobenzoic) to get heterocyclic derivatives quinazoline (C1-C2) and thiazinone (D1-D2 ) . All these compound characterized by13 C-NMR , FT-IR , 1HMNR . Then that,we studies the,biological,properties for,all heterocyclic  derivatives,to,ward.two different kindof bacteria.

Schmidt reaction by sulfonium ions is described. General primary, secondary, and tertiary alkyl azides were converted to the corresponding carbonyl or imine compounds without any trace of the activators. This bond scission reaction showcased ring-opening, -expansion, and one-pot further conversion of the substrates as well as the application with C-H azidation.

The aim of this study was to synthesize, characterize, and evaluate neoteric imine compounds for antimicrobial activity and hemocompatibility. Four compounds were synthesized using 3-thiophene carboxaldehyde, ethanol, amine, and acetic acid. The compounds were characterized using nuclear magnetic resonance (NMR) spectroscopy, Fourier transform infrared (FTIR) spectroscopy, differential scanning calorimetry (DSC), and powder X-ray diffraction (PXRD). A solubility study was conducted with various solvents and surfactants at 40 °C. An in vitro antimicrobial assay was performed against bacterial and fungal strains to determine the zone of inhibition and minimum inhibitory concentrations. Finally, an in vitro hemolysis study was conducted using rat erythrocytes. The structure of the compounds was confirmed by NMR, FTIR corroborated their functional group attributes, DSC determined their enthalpies of fusion and fusion temperatures, and PXRD confirmed their crystalline nature. These compounds were water-insoluble but soluble in chloroform, with a maximum solubility of ~80 mg/mL. The antimicrobial assay suggested that two of the products exerted potent activities against C. albicans and several bacterial strains. Finally, hemolysis analysis excluded the possibility of hemolysis at the assessed concentrations. In conclusion, two of the novel imine compounds showed promise as antimicrobial agents to control local and systemic microbial infections in a suitable dosage form.

The different halogen-containing derivatives of N-substituted quinone imines have been synthesized by the halogenation and hydrohalogenation of the corresponding quinone imines. N,N'-(Cyclohexa-2-en-1,4-diylidene)-diarylsulfonamides are good insecticides. They cause 89–97% of the insects to die. Compared with quinone imine, compounds having 4-oxocyclohexa-2,5-en-1-ylidene structure show higher fungicidal activity. N-(3,5-Dichloro-4-oxocyclohexa-2,5-dien-1-ylidene)-4-methylbenzene-1-sulfonamide and 4-chloro-N-[2,3,5,5,6,6-hexachloro-4-oxocyclohexa-2-en-1-ylidene]benzene-1-sulfonamide inhibit the growth and development of Phytophthora infestans by 82 and 81%, respectively. N-[2,3,5,5,6,6-Hexachloro-4-oxocyclohexa-2-en-1-ylidene]-4-methylbenzene-1-sulfonamide has a high herbicidal activity. The compounds with the largest number of chlorine atoms have the highest insecticidal, fungicidal, and herbicidal activity.
