Antitumoral and antiviral peptides

摘要

The invention relates to novel compositions of general formula (I) consisting of X 1 Trp Gly Gln X 2 or the pharmaceutically acceptable salts, ethers, or amides thereof, wherein X 1 is absent or contains at least one type of aminoacid, X 2 is absent or contains at least one type of aminoacid. The inventive compositions produce an antitumoral and antiviral effect by suppressing a tumoral cells proliferation, potentiating the action of other antitumoral preparations and by stimulating antitumoral and antiviral immunologic mechanisms.
