These new thymic facts analogs are of general formula I, A - Gly - Gly - Ser - Asn - B - C - NH - R (I) in which A is pGlu, Gln, Ala-Lys-Ser-Gln pGlu-Ala-Lys-Ser-Gln or, Gln-Ala-Lys-Ser-Gln B and C are Gly, Phe, Leu, Ala or a direct bond and R is H, and alkyl with 1 to 6 carbon atoms or a 2-phenylethyl. Depending on their chemical structure these new thymic factor analogs, possess either agonistic (immunostimulative) or antagonistic (immunosuppressory) properties. A …
