Provided is a method of treating multiple sclerosis employing certain phenol and benzamide compounds having the formula
wherein:
R1 and R2 are each independently hydrogen, C1-C6 alkyl C1-C6 alkoxy or
R3 and R4 are each independently hydrogen or C1-C4 alkyl;
n is an integer from 0 to 4, both inclusive;
m is 0 or 1; and
R5 and R6 are defined to be one of the following:
A) R5 and R6 are each independently hydrogen, C1-C8 alkyl, C3-C8 cycloalkyl, C2-C8 alkenyl, C2-C8 alkynyl, -(CH2)rnapthyl or
where q is an integer from 1 to 6, both inclusive, R7 and R8 are each independently hydrogen or C1-C4 alkyl, R9 is hydrogen, halo, C1-C4 alkyl, trifuoromethyl, hydroxy, amino, C1-C4 alkylamino, di(C1-C4 alkyl)amino, phenylamino or diphenylamino, and r is an integer from 0 to 4, both inclusive;
B) one of R5 or R6 is as defined in (A) above and the other is
wherein ma, na, R1a, R2a, R3a and R4a are the same substituent as m, n, R1, R2, R3 and R4, respectively; or
C) R5 and R6, taken together with the nitrogen atom to which they are attached, form
where R4 is as defined above and R10 is hydrogen, C1-C4 alkyl,
or (CH2)r-N(R7R8),
where R7, R8, R9 and r are defined above and s and t are each independently an integer from 0 to 4, both inclusive; to prepare a medicament for treating multiple sclerosis.
with the proviso that both m and n cannot be zero.
