Purpose: To prepare some 2-amino-4-(7-substituted/unsubstitutedcoumarin-3-yl)-6-(chlorosubstitute dphenyl) pyrimidines as antimicrobial agents. Methods: Some 2-amino-4-(7-substituted/unsubstitutedcoumarin-3-yl)-6-(chlorosubstitutedphenyl) pyrimidines were prepared by reacting 3-chlorosubstitutedphenyl-1-(7-substituted/unsubstituted coumarin-3-yl)prop-2-ene-1-ones with guanidine carbonate. The c...
The methanol leaf extracts of Acacia nilotica, Sida cordifolia, Tinospora cordifolia, Withania somnifer and Ziziphus mauritiana are ethnomedicinally important showed significant antibacterial and activity against Bacillus subtilis, Escherichia coli, Pseudomonas fluorescens, Staphylococcus aureus and Xanthomonas axonopodis pv. malvacearum and antifungal activity against Aspergillus flavus, Dresc...
Infectious diseases are one of the main causes of high morbidity and mortality in human beings around the world. Currently the marine is an important source of medicinal products since the marine ecosystem,particularly seaweeds are directly exposed and are susceptible to ambient micro organisms such as bacteria fungi and viruses. In the present study, we assessed the antibacterial and antifunga...
Applanoxidic acids and sterols, isolated from Ganoderma spp., were acetylated and/or methylated. The antibacterial activity against Escherichia coli and Staphylococcus aureus and the antifungal activity against Candida albicans and Trichophyton mentagrophytes of the derivatives were investigated by a microdilution method, and compared with those of the natural products. Both natural and modifie...
BACKGROUND Herbal medicines have long been used for various ailments in various societies and natural bioactive compounds are gaining more and more importance due to various factors. In this context, three plant species i.e., Eryngium caeruleum, Notholirion thomsonianum and Allium consanguineum have been aimed for the scientific verification of their purported traditional uses against various i...
A number of benzothiazole-2-ylsulfanyl derivatives 2(1,3-Benzothiazol-2-ylsulfanyl)alkanoylhydrazide (IA – IG) and 5-[1-(1,3-Benzothiazol-2-ylsulfanyl)alkyl]-1,3,4-thiadiazole-2(3H) thione (IIA-IIG) have been synthesised from (1,3Benzothiazol-2-ylsulfanyl)acetic acid. These compounds were synthesied and characterized from their F.T.I.R, and H-NMR spectral studies. The compound (IIA to IIG) were...
Hexane, chloroform and aqueous extracts from Hemidesmus indicus and Ichnocarpus frutescens roots were evaluated for their antimicrobial activity. The chloroform extract of both plants showed antibacterial and antifungal activities against the tested organisms. Both the plants showed highest antibacterial and antifungal activity against Eschericia coli and Aspergillus flavus respectively. With i...
Phlebiakauranol aldehyde and the corresponding alcohol were isolated from cultures of Punctularia atropurpurascens. The aldehyde but not the alcohol exhibited strong antifungal activity against several phytopathogens as well as antibacterial and cytotoxic activities. Two acetylated derivatives prepared from the aldehyde showed only very weak antifungal and antibacterial and moderate cytotoxic a...
The antifungal and antibacterial investigations were carried out of some Schiff bases obtained by condensation of di-methyl amino benzaldehyde and fluoro, bromo, nitro, methyl, methoxy and ethoxy substituted anilenes. The aforementioned studies were also carried out after complexing the above compounds with certain metals Co, Ni, Rh, Os, Pt. The results reveal that some of the compounds show si...
Using molecular modeling approach, potential antibacterial agents with triazole core were proposed. A moderate to weak level of antibacterial activity in most of the compounds have been observed, with best minimal inhibitory concentration (MIC) value of 0.003 mg/mL, as shown by the 15 against S. epidermidis. Studied compounds were also submitted to the antifungal assay. The best antifungal acti...
