Derivatives (halogen, nitro and amino) of 8-hydroxyquinoline with highly potent antimicrobial and antioxidant activities
8-Hydroxyquinoline (8HQ) compounds have been reported to possess diverse bioactivities. In recent years, drug repositioning has gained considerable attention in drug discovery and development. Herein, 8HQ (1) and its derivatives (2-9) bearing various substituents (amino, nitro, cyano and halogen) were investigated for their antimicrobial against 27 microorganisms (agar dilution method) and anti...
متن کامل3-Nitro, 1-Amino Guanidine and 5-Hydrazino-1H-Tetrazole Derivatives as New Energetic Materials
The synthesis of 3-amino-1-nitroguanidine (3-ANQ) and 5-hydrazino tetrazole (5-HT) derivatives as new energetic materials are described. Reaction of 3-ANQ with triethyl orthoformate leads to the formation of 3-nitramino triazole while no reaction was observed whit 5-HT. Addition of NaN3 to a mixture of 3-ANQ and triethyl orthoformate, afforded 1-nitroguanidyl tetrazole in excelle...
متن کامل2-Amino-5-nitro-N-[(E)-thiophen-2-ylmethylidene]aniline
In the title mol-ecule, C(11)H(9)N(3)O(2)S, the thio-phene and benzene rings form a dihedral angle of 17.68 (9)°. The thio-phene S atom and the imine N atom are syn with respect to each other. In the crystal, N-H⋯O and N-H⋯N hydrogen bonds connect mol-ecules, forming a two-dimensional network parallel to (10-1).
متن کامل2-Amino-6-nitro-1,3-benzothiazol-3-ium hydrogen sulfate
In the title molecular salt, C(7)H(6)N(3)O(2)S(+)·HSO(4) (-), the 2-amino-6-nitro-1,3-benzothia-zole ring system is essentially planar [mean deviation = 0.0605 (4) Å]. In the crystal, N-H⋯O and O-H⋯O hydrogen-bonding inter-actions result in a layer motif.
متن کامل2-Amino-6-nitro-1H-benzoimidazol-3-ium chloride
In the cation of the title compound, C(7)H(7)N(4)O(2) (+)·Cl(-), the benzimidazole ring system is planar with a maximum deviation of -0.019 (3) Å. In the crystal structure, C-H⋯Cl, N-H⋯Cl, and N-H⋯Cl inter-actions link the mol-ecules into a two-dimensional network. π-π contacts between benzimidazole rings [centroid-centroid distances = 3.928 (1) and 3.587 (1) Å] may further stabilize the struct...
