DNA gyrase and Topoisomerase IV are promising antibacterial drug targets as they regulate bacterial DNA replication and topol. In a quest for novel DNA topoisomerase inhibitors, a multidisciplinary approach was adopted that involves computational prediction of binding sites and mol. modeling followed by green synthesis and biol. evaluation of antibacterial activity of spirobenzimidazo quinazolines derivatives Using basic quantum chem. principles, we evaluated spirobenzimidazo quinazolines derivatives with their pharmacokinetic profiles. Based on the results of the aforesaid in-silico studies, we synthesized a series of titled compounds using green synthetic methodol. that were validated as potential antimicrobial agents. Quantum chemoinformatics based predicted activity for the synthesized compounds 9b, 9c, and 9j was concomitant with biol. evaluation of broadspectrum antibacterial activity. Biol. evaluation revealed that inhibition of biofilm formation was due to their potential antibacterial activity. We believe that the novel spirobenzimidazo quinazolines have the potential to be alternatives to aminocoumarins and classical quinazolines upon detailed target specific biol. studies.

The article contains the following contents:

Combining triphenylamine (TPA) and 2-(1H-benzo[d]imidazol-2-yl) aniline (BI), a typical fluorescent dye, TPA-BI, was designed and synthesized. The photo-phys. properties of this compound were investigated both in solution and the solid state. TPA-BI showed a strong AIEE effect and its relative fluorescence quantum yield (φ_f) was up to 63.4% in the aggregation state. The tunable fluorescence phenomenon by the MCF effect was observed between the amorphous (bluish violet) and crystalline (green) states, and the absolute φ_f was determined to be 56.2% and 21.9%, resp., by the integral sphere method. Meanwhile, pH titration experiments exhibited the tunable fluorescence phenomenon in different pH solutions Thus, TPA-BI could also be used as a fluorescent switch from green to bluish-violet based on its response to volatile acidic and alk. organic compounds in the solid state repeatedly without fatigue and destruction under UV illumination (365 nm), which can be explained by the reversible transformation by protonation and deprotonation. The protonation process was further confirmed in detail by ¹HNMR titration experiments D. functional theory (DFT) and time-dependent d. functional theory (TD-DFT) were used to predict the multi-stimuli responsive fluorescence properties. And 2-(1H-Benzo[d]imidazol-2-yl)aniline (cas: 5805-39-0) was used in the research process.

A comparative study between two methods, (microwave-assisted and conventional heating approaches), was performed to synthesize a new quinazoline derivative from 2-(2-aminophenyl)-1H-benzimidazole and octanal to produce 6-heptyl-5,6-dihydrobenzo[4,5]imidazo[1,2-c]quinazoline (OCT). The compound was characterised using FTIR, ¹H and ¹³C NMR, DIMS, as well as X-ray crystallog. The most significant peak in the ¹³C NMR spectrum is C-7 at 65.5 ppm which confirmed the cyclization process. Crystal structure anal. revealed that the mol. growed in the monoclinic crystal system P2₁/n space group and stabilized by an intermol. hydrogen bond between the N1-H1A···N3 atoms. The crystal packing anal. showed that the mol. adopts zig-zag one dimensional chains. Fluorescence study of OCT revealed that it produced blue light when expose to UV-light and its quantum yield equal to 26%. Antioxidant activity, which included DPPH· and ABTS^·+ assays was also performed and statistical anal. was achieved via a paired T-test using Minitab 16 software with P < 0.05. Also, the antimicrobial assay against two Gram-pos., two Gram-neg., and one fungus was screened for these derivatives Using microwave to synthesize OCT have drastically reduced reaction time, and increased yield. OCT showed good antioxidant activity in one of the tests and moderate antimicrobial activity.
