IMMUNOACTIVE PEPTIDES, FK-156 AND FK-565. III

Studies on a new immunoactive peptide, FK-156. II. Fermentation, extraction and chemical and biological characterization.

An interesting immunoactive peptide, FK-156, has been isolated from the fermentation broth of Streptomyces olivaceogriseus sp. nov. and Streptomyces violaceus. The compound was purified by column chromatography with activated carbon, ion exchange Sephadex and cellulose powder. FK-156, obtained as white powder, exhibits a wide variety of immunostimulatory activity in vivo and in vitro with exper...

Cesàro semiconservative FK spaces

In this paper we call an FK space X containing φ a Cesàro semiconservative space if X ⊂ σs holds. Therefore we give some characterizations of these spaces. AMS subject classifications: Primary 46A35, 46A45; Secondary 47B37, 40C05

Notes on FK 506.

FK 506 versus cyclosporine.
