摘要:
Cyclic peptides are produced by the controlled aerobic fermentation of Streptomyces silvensis, ATTCC No. 53525 or ATCC No. 53526. These compounds are antagonists of oxytocin and are useful in the treatment of preterm labor and vasopressin and are thus useful in the treatment and prevention of disease states wherein vasopressin may be involved, for example congestive heart failure, hypertension, edema and hyponatremia.
摘要:
There is disclosed a series of macrolides isolated from the fermentation broth of a microorganism identified as MA-5000 which morphological analysis reveals to be a strain of Streptomyces hygroscopicus. The compounds structures are presented based upon analytical studies. The compounds have antifungal activity.
摘要:
Novel peptidyl derivatives of formula I are found to be potent inhibitors of interleukin-1.beta. converting enzyme (ICE). Compounds of formula I may be useful in the treatment of inflammatory or immune-based diseases of the lung and airways; central nervous system and surrounding membranes; the eyes and ears; joints, bones, and connective tissues; cardiovascular system including the pericardium; the gastrointestinal and urogenital systems; the skin and mucosal membranes. Compounds of formula I are also useful in treating the complications of infection (e.g., gram negative shock) and tumors in which IL 1 functions as an autocrine growth factor or as a mediator of cachexia. ##STR1##
