Abstract

The present invention is directed to compounds that act as analgesics and that have the structure of formula (I): ##STR1## wherein; Z is ##STR2## wherein, n is 1 or 2, and R.sub.0 is C.sub.6-12 aryl or C.sub.7-8 aralkyl; or R.sub.1 is selected from the group consisting of hydrogen; --NH--C.sub.1-6 alkyl; C.sub.1-6 alkyl; C.sub.6-12 aryl; C.sub.7-18 aralkyl; arginyl; and R.sub.30 NHC(.dbd.NH)--, wherein R.sub.30 is hydrogen, C.sub.6-12 aryl, C.sub.7-18 aralkyl, or C.sub.1-6 alkyl; R.sub.2 is hydrogen; C.sub.1-6 alkyl; or OH; R.sub.3 is C.sub.6-12 aryl; C.sub.7-18 aralkyl; --CH.sub.2 --C.sub.6 H.sub.2 R.sub.8 R.sub.9 ;or --CH.sub.2 --OHC.sub.6 HR.sub.8 R.sub.9, wherein each of R.sub.8 and R.sub.9 is independently, or hydrogen; R.sub.4 C.sub.6-12 aryl; C.sub.7-18 aralkyl; C.sub.1-12 alkyl; or a substituted or unsubstituted cyclohexyl; R.sub.5 is C.sub.1-6 alkyl; hydrogen; OH; halogen; SH; NO.sub.2 ; NH.sub.2 ; --NH--C.sub.1-6 alkyl; NH.sub.2 C (.dbd.NH--; NH.sub.2 C (.dbd.NH)--NH--; COOR.sub.31, wherein, R.sub.31 is hydrogen, or C.sub.1-6 alkyl; X is CH.sub.2 NHC(O)--; CH.sub.2 NHC(O)O; --C(O)NH--; or CH.sub.2 NH--; and L is a C.sub.1-12 alkylene chain which can be substituted with at…
