Macromolecular drugs acting as precursors of non-macromolecular active substances — Preliminary considerations

Pharmacological Research Communications, 1975
Summary Some principles at the basis of the potential interest of macromolecular drugs are defined. The main lines of a research on purposely tailored synthetic high polymers acting as precursors of non-macromolecular active substances are given. The chemical aspects of proper design of these polymers are discussed in detail.

MACROMOLECULAR STRUCTURES OF HUMIC SUBSTANCES

Soil Science, 1980
ABSTRACTWe investigated humic substances by surface pressure and viscosity measurements at different pHs and neutral salt concentrations to elucidate their macromolecular configurations. We observed that such configurations were not unique; they varied with the changes in the medium.

Modification of Macromolecular Substances

2012
The term “modification of macromolecular substances” is used for chemical and physical processes that are carried out after the actual synthesis, i.e., on the finished macromolecule. Chemical modifications are, for example, the conversion of ester side groups to hydroxy groups, chemical degradation and crosslinking reactions. Physical modifications are
