The present invention provides a compound having the structure: ##STR1## wherein R.sub.1 is a saturated or unsaturated linear or branched chain alkyl group, or a cholestanyl group; wherein R.sub.2 is a 2-indolyl, 3-indolyl, 4-indolyl, 5-indolyl, 4-hydroxyphenyl, 4-(arylalkyloxy)phenyl, 3,4-dihalophenyl, 4-hydroxy-3,5-dihalophenyl, 4-azidophenyl or 4-halophenyl group; wherein R.sub.3 is H, a linear or branched chain alkyl or alkenyl group, or a phenyl, 2-azidophenyl, 3-azidophenyl, 4-azidophenyl group, or an a alkenylacyl, 3-amino-3-butylpropyl, N-[N-(N-{4-azidobenzoyl}aminopropyl) aminopropyl], cis- or trans-cinnamyl, 2-amino-2-[(4'-azidophenyl)acetyl, (trifluoromethyl)aminoacetyl or D- or L-arginyl group bonded through the .alpha.-carbonyl moiety thereof; R.sub.4 is H, or a linear or branched chain alkyl group; wherein R.sub.5, R.sub.6 and R.sub.7 are independently the same or different and are H, a linear or branched chain alkyl group, an aryl group or an arylalkyl group; wherein n, j and t are each 0 or 1; wherein m, o, p, q, r and s are independently the same or different and are 0, 1 or 2; wherein r+s and m+o are each equal to 2; wherein, if j is 0, p+q is 2; wherein, if j is 1, then p is 1, q is 0 and R.sub.6 is H; and wherein * denotes a D or L configuration. The invention also provides a method of synthesizing the compound. Another aspect of the invention concerns a method of treating a subject afflicted by a disorder associated with binding of an etiological agent to a glutamate receptor.
