Claimed compounds have the formula ##STR1## wherein R.sup.1a and R.sup.1b independently represent (C.sub.1 -C.sub.6) alkyl; R.sup.2 represents (C.sub.1 -C.sub.10) alkyl or substituted (C.sub.1 -C.sub.10) alkyl wherein the substituents are independently from 1 to 3 of --SR.sup.7 ; R.sup.7 represents phenyl, or substituted phenyl wherein the substituents are independently 1-5 of halogen, trifluoromethyl, (C.sub.1 -C.sub.6) alkyl, (C.sub.1 -C.sub.6) alkoxy, nitro, cyano, or hydroxyl; R.sup.3 represents substituted (C.sub.1 -C.sub.6) alkyl wherein the substituents are 1-2 hydroxyl groups; G represents a substituent selected from the group consisting of halogen, (C.sub.1 -C.sub.6) alkyl, and OR.sup.4 wherein R.sup.4 is H or (C.sub.1 -C.sub.6) alkyl; and y is 0 or an integer of 1-3. Pharmaceutical compositions containing such compounds and methods of treatment of glucagon-mediated conditions by administering such compounds are also claimed.
