Merremia emarginata is a creeping herb, rooting at nodes, and commonly used in folk medicine. The current study was undertaken with the aim of preliminary phytochemical analyses, evaluation of antimicrobial activity, and antioxidant activity by methanol and aqueous extracts of leaves of Merremia emarginata. The extracts were subjected to preliminary phytochemical analyses; Antibacterial activities against nine bacterial strains were done by using agar – well diffusion method and free radical DPPH antioxidant activity. Preliminary phytochemical analyses were done by using standard phytochemical methods that showed the presence of Carbohydrates, reducing sugars, phytosterols, fixed oils, saponins, phenolic compounds and flavonoids. Based on the results of phytochemical analyses, methanol and aqueous extracts of the plant were chosen for antibacterial studies. Methanolic extract of leaves showed the highest antibacterial activity followed by the aqueous extract. The present study indicates that the leaves of Merremia emarginata possess antibacterial activity and found effective against eight bacterial cultures. Antioxidant activity of the DPPH assay showed that extracts exhibit the scavenging effect of various...

The facts like developing resistance in bacterial pathogens against conventional antibiotics, emergence of new infectious agents etc. have been leading the scientists to tedious research activities to find out antimicrobial drugs with novel modes of action. Among the multidrug-resistant (MDR) bacterial species that pose threat to human life, the IDSA has identified a group pathogens known as ESKAPE pathogens which show extensive drug resistance through a wide range of mechanisms. Silver nanoparticles (AgNPs) have been identified as very effective and to avoid the chemical contamination in preparation of them, green synthesis is being used. In the present study, AgNPs using Picrorhiza kurroa Royle ex Benth were synthesized using reduction method. The green synthesized AgNPs were characterized by UV–Vis, DLS-zeta potential and FESEM analysis. Anti-ESKAPE activity of the synthesized nanoparticles was also performed. FESEM studies revealed that the nanoparticles were spherical and nanosize in shape. The UV–Vis spectral studies confirmed the surface plasmon resonance of green-synthesized silver nanoparticles. The particle size was found to be 267 nm and the stability...

Angina Pectoris is the medical term for chest pain or discomfort due to coronary heart disease. The drawback of the marketed formulation is required repeated administration of the drug due to low bioavailability. Therefore, it utilized a nanotechnology technique for prevention of drawback of marketed formulation. Polymeric nanoparticles have been in preferential list when it comes to nano-drug delivery via oral route. Recent advances in lipid-reducing treatment, statins clinical research suggests that antimicrobial therapy is important to continue reducing cardiovascular events, beyond lipid-reducing therapy. A potential therapeutic choice for the residual risk is to intervene directly in the inflammatory process through a drug delivery system based on the nanotechnologies. Different nano-sized materials, including micelles, liposomes, polymer nano-particles, dendrimers, carbon nanotubes, and metal nanoparticles, are currently developed as by nanotechnology. It is a viable strategy since the inflammatory environment enhances the integration of nano-sized materials into a mononuclear phagocytic process. We have recently developed a polymeric nano pharmaceutical statin in order to optimize its anti-inflammatory properties. In the present review,...

Benzimidazole, a fused heterocyclic moiety containing benzene and imidazole, has gained considerable attention in the field of medicinal chemistry due to its wide array of pharmacological activities. Be it as a antifungal, anticancer agent, proton pump inhibitors, anthelmintic, anti-microbial, analgesic, it has become an intrinsic part of the pharmaceutical world. The presence of Nitrogen in its heterocyclic ring has made it a more biologically active pharmaceutical agent. The fact that benzimidazole residue is a constituent of vitamin B12 supports its potential use in therapeutics. Benzimidazole derivatives are the structural isosters of naturally occurring nucleotides such as purine, allow them to interact effectively with the biopolymers of the living system such as proteins, enzymes, and receptors. Benzimidazoles exhibit significant activity as a potential anti-tumour agent, smooth muscle cell proliferation inhibitors, a treatment for intestinal cystitis, and in a diverse area of medicinal chemistry. The synthesis of novel benzimidazole derivatives remains as the main focus of medicinal research. This current review covers the chemistry and significance of benzimidazole and its derivatives,...

In this planed research work, aryl piperazine derivatives will be synthesized because aryl piperazine currently the most important constructive block in drug discovery with positive pharmacological evaluation. A series N- (4- (benzo[d]thiazol-2-yl) phenyl)-2-[4-(aryl-substituted) piperazines-1-yl]acetamide, N-(4-(benzo[d]oxazol-2-yl)phenyl)-2-[4-(arylsubstituted)piperazines-1-yl]acetamide and Synthesis of N-(4-(benzo[d]imidazol-2-yl) phenyl)- 2- (4- (arylsubstituted)piperazin-1-yl) acetamide will be synthesized with their characterization such as melting point determination, Thin-layer chromatography (TLC) and spectral analysis. After that, pharmacological evaluation, such as antibacterial activity, will be performed for synthesized compounds. All the synthesized compounds were reported for determination of zone of inhibition (mm), minimum inhibitory concentrations (MIC) were also calculated for effective derivatives, with an objective to offer some potent antimicrobial agents to human beings. Antimicrobial activity is determined based on their in-vitro activity in pure cultures. In-vitro susceptibility testing is done by two methods i.e., Turbidimetric/photometric/tube dilution method and agar diffusion/cup-plate/cylinder plate...
