Riassunto L'inibizione da parte della guanidina sulla crescita del virus polio può essere antagonizzata da aminoacidi e amino-alcoli. Viene definita la struttura responsabile dell'effetto antiguanidinico negli amino-acidi attivi. Una struttura simile è presente anche negli amino-alcoli attivi. I risultati ottenuti suggeriscono che i composti antiguanidinici interagiscono con la molecola guanidinica sottraendola dai recettori connessi con l'effetto antivirale.

Thiamine transport by human intestine in vitro 总被引:1,自引:0,他引:1
Summary Surgical specimens of human gastrointestinal mucosa and muscle were incubated in vitro with thiaminethiazole-2-14C. Labelled thiamine uptake was uphill in mucosal tissues and downhill in muscle. Small intestinal mucosa accumulated labelled thiamine in a phosphorylated form, while gastric and colonic mucosa, as well as muscular layers of all gastrointestinal segments studied, did not.This work was supported in part by a grant from the Italian Research Council, Rome, Italy. 相似文献
