Mycophenolic acid suppresses granulopoiesis by inhibition of interleukin-17 production.

Mycophenolic acid is a commonly used immunosuppressant after organ transplantation and in autoimmune diseases; however, myelosuppression is a major complication despite its largely favorable side-effect profile. Mycophenolic acid targets inosine monophosphate dehydrogenase, which is essential for T-cell proliferation. The T-cell cytokine interleukin-17 (IL-17 or IL-17A) and its receptor maintai...

The intracellular teichoic acid from Lactobacillus arabinosus 17-5.

It has been shown that extracts of certain bacteria contain both glycerol teichoic acid and ribitol teichoic acid, although the walls of these organisms contain only the ribitol compounds (Armstrong, Baddiley, Buchanan, Carss & Greenberg, 1958). The conclusion that glycerol teichoic acids occur in an unspecified region beneath the wall was substantiated in a more extensive survey (Baddiley & Da...

Further mulinane and azorellane diterpenoids isolated from Mulinum crassifolium and Azorella compacta.

The new mulinane diterpenoids 1 and 2 were isolated from the EtOAc extract of Mulinum crassifolium, while the rearranged mulinane 5, which was isolated for the first time from a natural source, was isolated from Azorella compacta. Compounds 1-2 were prepared by semi-synthesis thorough acetylation of the diterpene 17-acetoxymulinic acid (3). A mechanism of reaction was proposed, while the struct...
