SO-75R1, a new mutactimycin derivative produced by Nocardia brasiliensis.

In the course of studies on biologically active substances from pathogenic microorganisms, a new antibiotic SO-75R1 was isolated from the mycelium of Nocardia brasiliensis IFM 075. This paper describes the fermentation, isolation and structural elucidation of SO-75R1. The seed broth was prepared by inoculating mycelial elements of the producing strain (IFM 075) grown on Sabouraud dextrose agar ...

A study on the effect of ion chelating agent on Alzheimer disease

Background: A new type of treatment is still needed for sporadic Alzheimer disease. The ion chelating agent (such as M30 and HLA-20) and other kinds of ion chelating agent possess brain tissue permeability. At present, the study has confirmed that ion chelating agent possesses a certain neuroprotective effect on neural degenerative disease. The objective of this study is to explore the related ...
