摘要:
The synthesis of useful peptides presents a promising approach to new theeutic agents. The Dolastatins, a series of linear and cyclic antineoplastic and/or cytostatic peptides isolated from Indian Ocean sea hare Dolabella auricularia represent excellent leads for synthetic modification.The extraordinary inhibition of cell growth shown by the pentapeptideamides against six major types of human cancer has been presented. The intermediates of these reaction also show anticancer activity against the murine P388 lymphocytic leukemia cell line.
摘要:
The synthesis and elucidation of nineteen heterocyclic or halophenyl amideerivatives of dolastatin 10 are disclosed. These compounds and the methods of producing those compounds offer demonstrated significant in vitro activity against several human cancer cell lines. These compounds and the methods of producing those compounds offer a commercially viable alternative to natural and synthetic dolastatin 10.
摘要:
Compounds, methods and compositions are provided for inducing natriuresis in a mammal. Methods for isolating and synthesizing the natriuretic compounds are also provided. Therapeutic methods using the natriuretic compounds are also provided. The natriuretic compounds are capable of inducing sodium excretion in a mammal without inducing corresponding prolonged potassium excretion.
摘要:
2-Adamantyl- and 1-adamantyl-D/L-glycyl-L-alanyl-D-isoglutamine and their derivatives of the formulae ##STR1## wherein R stands for a hydrogen atom or a MurNAc group, and hydrochlorides thereof,a process for the preparation thereof and their use to obtain pharmaceuticals, which are particularly indicated for the treatment of viral diseases and tumors and/or immunomodulations in humans and animals.
