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.
摘要:
The invention relates to medicine, and more specifically to pharmacology, and in particular to synthetic biologically active derivatives of pyrimidine, and it is designated mainly for use as antiviral, immune-stimulating, antichlamydial, antituberculous, psychodepressant, analgesic, and hepatoprotective remedies. Besides that, these compounds may be used for treating malignant neoplasms, and also in veterinary. The objective of the invention is obtaining new chemical substances possessing pronounced biological activity of wide range. The proposed objective is achieved by synthesis of 2,4-dioxo-5-arylidenimino-1,3-pyrimidines of the general formula where R is chosen out of group H, OH, alkoxyl, dialkylamino, benzo, dibenzo, or 3,4-dioxolano General method of producing the claimed compounds and example of synthesis, a list of 25 compounds synthesized and tested, results of identification, and data on wide comparative testing their biological properties and toxicity are presented.
