A compound of the formula:
wherein R¹ and R² are the same or different and independently represent tert-alkyl or phenyl; R³ represents hydrogen or alkyl; X represents -(CH₂)w-B-(CH₂)y- wherein B represents O, S, or CH₂ and w and y can each independently be an integer from 0 to 3 with the proviso that the sum of w+y is equal to or less than 3; A represents O or S(O)n wherein n is 0, 1, or 2; p is an integer from 0 to 4; and R represents:
(a) alkyl;
(b) OH;
(c) OR⁴ wherein R⁴ is alkyl of about 1 to about 4 carbon atoms;
(d) NR⁵R⁶ wherein R⁵ is hydrogen or alkyl, and R⁶ is hydrogen, alkyl, heterocyclealkyl, substituted heterocyclealkyl, cycloalkyl, substituted cycloalkyl, phenyl, substituted phenyl, phenylalkyl, or substituted phenylalkyl, or NR⁵R⁶ together form a heterocyclic ring which may optionally be substituted; or
(e) (CH₂)tCOOR⁷ wherein t is an integer from 1 to 4 and R⁷ is hydrogen or alkyl of 1 to 4 carbon atoms;
or a pharmaceutically acceptable salt thereof.
