A method for the treatment of cerebrovascular disorders and/or disorders associated with cerebral senility and/or other disorders which method comprises the administration of an effective, non-toxic amount of a compound of formula (I):
or if appropriate a pharmaceutically acceptable salt thereof, wherein R1 and R2 each independently represent alkyl or a moiety of formula (a):
—(CH2)m−A (a)
wherein m represents zero or an integer 1, 2 or 3; A represents a substituted or unsubstituted cyclic hydrocarbon radical; and R3 represents a halogen atom, a nitro group, or a group −NR4R5 wherein R4 and R5 each independently represents hydrogen, alkyl or alkylcarbonyl or R4 and R5 together with the nitrogen to which they are attached forming an optionally substituted, heterocyclic group; certain novel compounds falling within formula (I) and compositions comprising such compounds.
