Alimentary plants were screened for antibacterial activity against a penicillin G resistant strain of Staphylococcus aureus. Twenty-five samples of plant material corresponding to 21 species from 13 families were used. Both aqueous and ethanol extracts were obtained from them. Antibacterial activity
The present study aimed to investigate the efficacy of traditionally used anti-mastitis plants (Allium sativum, Bunium persicum, Oryza sativa and Triticum aestivum) in northwest Pakistan against bacterial pathogens. Selected plants were phytochemically screened for Alkaloids, Flavonoids, and
Cancer is a serious threat to human health. With the increasing resistance to known drugs, it is still urgent to find new drugs or pro-drugs with anti-tumor effects. Natural products produced by microorganisms have played an important role in the history of drug discovery, particularly in the
A family of fifteen quaternary ammonium salts (QAs), bearing the 1,2-bis(4-pyridyl)ethane core, were obtained using for the first time two different green methods, such as microwave (MW) and ultrasounds (US) irradiation, with very good yields and in much shorter times compared to the classical
Hevein, a well-studied lectin from the rubber tree Hevea brasiliensis, is the title representative of a broad family of chitin-binding polypeptides. WAMP-1a, a peptide isolated from the wheat Triticum kiharae, shares considerable similarity with hevein. The peptide possesses antifungal,
Puroindolines are two small proteins so called for the presence of an hydrophobic tryptophan-rich domain. Associated to wheat starch granules in Triticum aestivum, puroindolines have been shown to be responsible for the softness of the wheat endosperm. Moreover, have been proved to possess
Puroindolines, for years largely investigated for their involvement in wheat kernel hardness, have recently attracted attention thanks to their possible role as antimicrobial proteins. With the aim to enhance our knowledge of these proteins we studied their localization in the kernel, and their
Analogs (1----6) of diaminopimelic acid have been synthesized and tested for inhibition of meso-diaminopimelate decarboxylases from Bacillus sphaericus IFO 3525 and from wheat germ (Triticum vulgaris). Difluoromethyl diaminopimelate 1 does not irreversibly inactivate or strongly competitively
Bacterial leaf streak (BLS), caused by Xanthomonas translucens pv. undulosa, has re-emerged as an important disease of wheat (Triticum aestivum) in the United States. Planting resistant varieties is the best approach to manage BLS in the absence of effective bactericides. However, most of the wheat
