TL;DR: The title compound, C23H15BrClFN4O, is an analogue of sedatives such as midazolam and alprazolam, and its geometrical parameters are normal and comparable with those of related compounds as discussed by the authors.
Abstract: The title compound, C23H15BrClFN4O, is an analogue of sedatives such as midazolam and alprazolam. Its geometrical parameters are normal and comparable with those of related compounds. The only possible significant inter­molecular inter­action is a C—H⋯O bond.

Journal ArticleDOI
TL;DR: The results showed that the pyrazoline derivative is better at inhibiting growth of both types of bacteria (Gram-positive and Gram-negative) compared to chloramphenicol.
Abstract: A chalcone was prepared by the reaction of terephthalaldehyde with 3-acetyl-2,5-dimethylthiophene. Treatment of this chalcone with thiosemicarbazide/phenyl hydrazine/guanidine hydrochloride/thiourea afforded the corresponding pyrazoline, pyrazole, and pyrimidine in good yields. All the new compounds have been characterized by IR, 1H-NMR, 13C-NMR, GC-MS and elemental analyses. The anti-bacterial activity of these compounds were first tested in vitro by the disk diffusion assay against two Gram-positive and two Gram-negative bacteria, and then the minimum inhibitory concentration (MIC) was determined with the reference of standard drug chloramphenicol. The results showed that the pyrazoline derivative is better at inhibiting growth of both types of bacteria (Gram-positive and Gram-negative) compared to chloramphenicol.
