Objective: The aim of the present work was to synthesize and characterize a series of 6substituted benzimidazole-2-carbamic acid derivatives and evaluate them for antimicrobial activity. Methods: A novel series of 6-substituted benzimidazole-2-carbamic acid derivatives (6a-f) were synthesized by reacting substituted benzyl chlorides (2a-c) with 4-hydroxy -2nitro aniline (3) in the presence of a...
Either the whole plant or plant products having medicinal properties are commonly known as medicinal plants. These medicinal plants are known to possess various phytochemicals, which exhibit more bioactivities such as antibacterial, antifungal, anticancer activity, etc. In this study, Aegle marmelos was collected from Chennai, crude extract of fruit and pulp of the chosen plant was subjected fo...
Bacterial resistance has been increasingly reported worldwide and is one of the major causes of failure in the treatment of infectious diseases. Natural-based products, including plant secondary metabolites (phytochemicals), can be exploited to ameliorate the problem of microbial resistance. The fruit essential oils of Alchornea cordifolia and Canthium subcordatum were obtained by hydrodistilla...
The aerial parts of Centaurea deusta Ten. afforded in addition to several known compounds, mainly sesquiterpene lactones, one new eudesmanolide and one new elemane derivative. Structures of the new compounds were elucidated by spectroscopic methods. The in vitro antifungal and antibacterial activities of the isolated compounds was tested, using the microdilution method. All compounds tested sho...
Bacillus velezensis GQJK49 is a plant growth-promoting rhizobacterium with antifungal activity, which was isolated from Lycium barbarum L. rhizosphere. Here, we report the complete genome sequence of B. velezensis GQJK49. Twelve gene clusters related to its biosynthesis of secondary metabolites, including antifungal and antibacterial antibiotics, were predicted.
Two series of chloroisatin-3-semicarbazones and hydrazones have been designed and prepared by condensing 4-chloro and 6-chloroisatin with several substituted semicarbazides and related bioisosteric hydrazides, respectively. Investigation of in vitro antimicrobial activity of compounds has been performed by agar double dilution method against nine pathogenic bacteria and four pathogenic fungi. T...
Angelica dahurica (Fisch. Ex Hoffm) is an important traditional Chinese herb which is widely used in curing acne, ulcers, carbuncles, rheumatism, headaches and toothaches. A systematic antifungal bioassayguided fractionation of the ethyl acetate extract from A. dahurica led to the isolation of six coumarins, namely, suberosin, bergapten, alloimperatorin, xanthotoxol, 5-methoxy-8-hydroxypsoralen...
The present study deals with antimicrobial activity of ayurvedic drugs containing single herb (Amalaki Choorna and Yastimadhu Choorna) and combination of herbs (DN-90 and Asanadi Kwatha Choorna). Disc diffusion method was used to assess antibacterial activity and antifungal activity was tested using Poison food technique. Absence of bacterial growth around the discs impregnated with the aqueous...
Objective: This study observed the antibacterial, antifungal (aquatic and pathogenic fungi), and anthelmintic properties of Lactobacillus plantarum (LP) KP894100 and Lactobacillus acidophilus (LC) KP942831, isolated from a dairy product. Methods: Lactic acid bacteria traditionally used to improve human health. For in vitro antibacterial, antifungal, and antihelminthic studies of intracellular c...
Regarding the revealing side effect of chemical medications, such as antimicrobial resistance and etc, herbal medications have been considered as one of potential alternative to chemical one. The main purpose of this study was to evaluate the in vitro antibacterial effect of lavender ( Lavandula angustifolia) and ajwain ( Trachyspermum ammi) essential oil on two important rainbow trout bacteria...
