background and objectives: the artemisia genus of asteraceae family is represented by 34 species in iran. artemisia sieberi grows wild in different regions of iran and grows in desert and semi- desert climate and has forage value for animals and also medicinal properties for humans. in this study we examined the antimicrobial effects of a. sieberi. materials and methods: the antimicrobial activ...
Rising cases of antibiotic-resistant bacteria is a public health concern. Many approved antibiotics target penicillin-binding proteins example peptidoglycan transpeptidase (PTPase). Due to wide pharmacological activity of phenothiazines, new styryl, aryl, alkynyl, and thiophenyl benzo[a]phenothiazines were synthesized and their inhibitory potency against PTPasein silico and Gram-po...
The objective of the present study was to prepare controlled release formulation of Moxifloxacin hydrochloride ocular nanoparticles. The nanoparticles were prepared by solvent displacement method using Eudragit RL 100 as a polymer. Different formulations were prepared by varying the ratios of drug and polymer and varying the ratios of organic and aqueous phase. The formulations were evaluated i...
Abstract Background Pediatric infectious disease is one of the main problems in cancerous children that treat by chemotherapy drugs. Thus, study in this regard is necessary. The aim of this study was to evaluate antimicrobial properties of ethanolic extract of Ziziphus Jujuba fruits against different infectious pathogens. Materials and Methods This study is descriptive. In vitro antimicro...
The resistance of antimicrobials has become a global hazard with the irrational use of antibiotics. Infection of drug-resistance bacteria seriously threatens human health. Currently there is an urgent need for the development of novel antimicrobial agents with new mechanisms and lower levels of toxicity. In this paper, a series of (S,Z)-4-methyl-2-(4-oxo-5-((5-substitutedphenylfuran-2-yl) methy...
background: artemisia species with common persian name of dermaneh are found all over iran and are used for treatment in infectious diseases such as malaria, hepatitis and other diseases. some artemisia species are used in traditionally as tonic and anti-helmintic in north of iran. objective: the aim of this study was to investigate chemical composition of the essential oil of artemisia hausskn...
Background and Objectives: Since infectious microbial diseases belong to the most common sicknesses in the world, it is necessary to discover and explore new antibacterial materials. Mentha Piperita Lamiaceae is one of the most consumed medicinal plants in the world; having outstanding antimicrobial, pesticide, antiparasitic, antifungal and therapeutic properties. Therefore, aim of this study w...
conclusions due to phenolic content, methanolic extract of m. piperita has moderate antibacterial and antifungal properties against the aforementioned gram positive and gram negative bacteria and fungi strains. materials and methods the methanolic extract was prepared by standard procedure, and total phenol, total flavonoid, and total anthocyanin content were determined using a spectrophotomete...
Novel analogues of N-piperazinyl fluoroquinolones were prepared and evaluated against a panel of Gram-positive and Gram-negative bacteria, to study the effect of introducing bulky anthracene and phenanthrene moieties on the antibacterial effects of norfloxacin, ciprofloxacin and gatifloxacin. Although most of the novel synthesized compounds had lower antibacterial effects, some derivatives show...
