Design, Synthesis and Pharmacological Evaluation of Pyrazoline Substituted Benzimidazole Derivatives as Antibacterial and Antifungal Agents
Abstract: Background: Benzimidazoles are important heterocyclic compounds possessing a variety of biological activities such as anticancer, antioxidant, antiinflammatory, analgesic, anti-viral, anti-bacterial, anti-fungal and hypoglycemic activities. Pyrazolines are used as antitumor, immunosuppressive, antibacterial and anti tubercular agents. Aim : The present research focused on incorporating pyrazoline nucleus into benzimidazole nucleus to form a potent antibacterial and antifungal agent. Method: The in silico design of novel pyrazoline substituted benzimidazole derivatives was done using …

Synthesis and Chemical Characterization of Novel Series of Heterocyclic Compounds Containing Nitrogen and Oxygen
Abstract: The aim of this study is to synthesize some novel pyrazoline derivatives and to study their antibacterial activity. As estimated, pyrazoline derivatives exhibited significant to moderate antimicrobial activity. There is no such obsession as completely safe drug. Drugs are prevailing tool, which modify physiological processes for the enhanced or for the worse. A society, which desires to take advantage from them, it will not accomplish all the benefits open to …

Synthesis of new heterocyclic compounds containing nitrogen, sulphur and study their biological activity
Abstract: Several substituted pyridines with brominated coumarin and with other substituents were achieved by condensing brominated coumarin IV with 4-methoxybenzaldehyde in basic solution forming α,β-unsaturated ketone II. Hantzsch reaction of this ketone with β-ketoester to provide precursor substituted pyridines. The Hantzsch reaction product was subjected to different reactions. The other targeted heterocyclic compound was obtained by reaction of α,β-unsaturated ketone II with hydrazine carbothioamide to give substituted pyrazole with brominated coumarin, …

Synthesis and Anti-Bacterial Activity Profile of Cyclized Diazonium Compounds
Abstract: Synthesis of cyclised diazonium compounds and their in vitro activity against various microorganisms is described. Several primary aromatic amines were diazotised and the resulting diazotised compounds were coupled with active methylene compounds to give hydrazono derivatives. These were cyclized with hydrazine hydrate, phenyl hydrazine, urea and o-phenylene diamine to give pyrazolin-5-one, substituted pyrazolin-5-ones, pyrimidin-di-ones and benzodiazepinone derivatives, respectively. Some hydrazine derivatives were also produced by reduction of diazo compounds with …

Photochemical Insights into Light: Responsive Heterocyclic Compounds
Abstract: eterocyclic compounds are significant in a wide range of chemical fields. They are crucial components of the structural makeup of bioactive substances. Such compounds can be conveniently transformed through photochemical processes. Chemical reagents are rarely utilized. It is possible for members of one compound family to change into members of another. There is discussion of three key categories of photochemical rearrangements involving heterocyclic compounds: Photochemical reactions involving hydrogen atom transfer …
