Benzimidazole is a bicyclic heterocyclic aromatic compound in which benzene fused to imidazole moiety. holds vital role the field of medicinal chemistry possesses wide variety pharmacological activities like antibacterial, anti cancer, antifungal, antileishmanial, tubercular, viral and malarial respectively, hence benzimidazole moiety attracting chemist synthesize different derivatives with act...
New heterocyclic compounds contain triazole ring (play very important role in photostabilization as UV absorber) synthesized by reaction between the di Schiff base (compound 3) with aromatic alkyl halide (Benzyl bromide) and shows there activity photostabilizer for polystyrene through exposure to UV-Light (300 hours). Finally Infrared spectroscopy, 1H-NMR, 13C-NMR instrumental methods were used...
heterocyclic derivative contain triazole ring was synthesized and characterized the product their structures by infrared spectroscopy, 1H-NMR, 13C-NMR instrumental techniques. Compound (4) reacting of Schiff base (3) with an three moles alkyl halide (p-phenyl phenacyl bromide). Final played important role in photostabilizer polymer (PS), showed activity as a when exposed to UV light (300 hours).
Reactions of 4-hydroxycoumarin 1 with heterocyclic aldehydes 2-4 led to bis-4-hydroxycoumarin derivatives 5-7 under microwave irradiation as well the classical heating. The subsequent reactions products are described. 4,4’-Epoxydicoumarins 8, 9 were prepared by reaction in acetic acid / p-toluenesulfonic medium. Compound 10 was 5 anhydride presence sodium acetate. Dioxocine-1,15-dione 11 6 dich...
The compounds synthesized in this research were designed with the goal of establishing a new paradigm for mixed-base-pair DNA sequence-specific recognition. The design scheme starts with a cell-permeable heterocyclic cation that binds to AT base pair sites in the DNA minor groove. Modifications were introduced in the original compound to include an H-bond accepting group to specifically recogni...
Indolo[2,1-b]quinazolin-6,12-dione (tryptanthrin) derivatives present important types of nitrogen-containing heterocyclic compounds which are useful intermediate products in organic synthesis and have potential pharmaceutical applications. The new ethyl 5-oxo-5-(((12-oxoindolo[2,1-b]quinazolin-6(12H)-ylidene)amino)oxy)pentanoate (Compound 2) was synthesized. Compound 2 is the first example a tr...
Heterocyclic compounds are of very much interest in our daily life. Heterocyclic compounds have one or more hetero atoms in their structure. They may be cyclic or non cyclic in nature. Heterocyclic compunds have a wide range of application. They are predominantly used as pharmaceuticals, as agrochemicals and as veterinary products. They also find applications as sanitizers, developers, antioxid...
In the title compound, [Mn(CHO(2))(2)(C(12)H(10)N(4))(2)](n), the Mn(II) atom and the benzene ring of the ligand lie on an inversion centers. The Mn(II) atom has an octa-hedral coordination environment composed of four N atoms from two different symmetry-related N-heterocyclic ligands forming the basal plane, and two O atoms from symmetry-related formate anions occupying the apical positions. T...
In the title compound, C(4)H(5)N(3)OS(2)·2C(2)H(6)OS, the five-membered heterocyclic ring and the N-(C=O)-C plane of the acetamide group are essentially co-planar, with a dihedral angle of 1.25 (3)°. Inter-molecular N-H⋯O hydrogen bonds between the acetamide compound and the dimethyl sulfoxide mol-ecules stabilize the crystal structure. The two dimethyl sulfoxide mol-ecules are each disordered ...
