Dendrimers are a new class of polymeric materials. They are highly branched, monodisperse macromolecules. The structure of these materials has a great impact on their physical and chemical properties. As a result of their unique behaviour dendrimers are suitable for a wide range of biomedical and industrial applications. The paper gives a concise review of dendrimers' physico-chemical propertie...
Malonyl-4,5-dihydroniphimycin was isolated as a new antibiotic from the mycelium of Streptomyces hygroscopicus 15. The chemical constitution was elucidated from the physico-chemical properties, using NMR techniques and mass spectrometry, to be a 36-membered macrolide related to non-polyenic antibiotics. Malonyl-4,5-dihydroniphimycin displays activity against filamentous fungi and Gram-positive ...
