9-beta-D-Arabinofuranosyladenine (ara-A) was produced by a new species of Streptomyces designated as S. herbaceus. Ara-A was found to have potent herbicidal activity against Echinochloa crus-galli, Digitaria adscendens and Chenopodium ficifolium by the treatment with ara-A before germination of these plants. However, Oryza sativa had strong resistance to(More)
Herbimycin, a new antibiotic, was isolated from the fermentation broth of Streptomyces hygroscopicus strain No. AM-3672, a soil isolate. The molecular formula of herbimycin was determined to be C30H42N2O9. Herbimycin was found to have potent herbicidal activity against most mono- and di-cotyledonous plants, especially against Cyperus microiria STEUD.(More)
The endothelium is a monolayer of cells that lines the inner surface of vessels and plays a crucial role in maintaining hemostatic balance [1]. All blood vessels, from the largest arteries and veins to the smallest venules are lined with endothelial cells, which prevent thrombosis via anticoagulant and antiplatelet mechanisms.
