摘要:
A compound having the formula ##STR1## or a pharmaceutically acceptable salt thereof, wherein A is an amino acid identifying group; B is a hydrogen atom, an alkyl group having 1-5, inclusive, carbon atoms, or an aralkyl group having 6-12, inclusive, carbon atoms; carbon atom 2 is of the R configuration; and carbon atom 3 is of the R configuration. The compounds of the invention are effective in augmenting immunological responses and are useful therefore in the treatment of diseases such as cancer, viral infections, bacterial infections, and arthritis.
摘要:
A compound having the formula ##STR1## or a pharmaceutically acceptable salt thereof, wherein A is N-AC-Sar, pGlu, or homo-pGlu-; B is an aryl group, a heteroaryl group, a cycloalkyl group, an aralkyl group, a heteroalkyl group, a heteroaralkyl group, a benzoyl group, an alkyl group, an acetyl group, or a substituted aryl group wherein the substituent is halogen, hydroxy, alkoxy, nitro, cyano, or hydroxyalkyl; E is H or an alkyl group; B and E being separate substituents or, together with C.sub.1 and the nitrogen atom to which B is attached, forming a 5,6, or 7-membered ring; m is an integer between 0 and 4; either F is ##STR2## wherein R is an alkoxy group or an aralkoxy group; or F is ##STR3## and is capable of forming a 6-membered ring with the nitrogen atom of A, provided that F can only be ##STR4## forming a ring with A when A is pGlu or homo-pGlu.
