Latest Patents

One of her latest patents is an improved anti-ulcer composition designed for the prophylaxis and treatment of stomach and duodenum ulcers, including stress ulcers. This innovative composition provides potent anti-ulcer activity while dramatically reducing toxicity and harmful side effects. It comprises a histamine H₂ antagonist based on a guanidine derivative, specifically [N-cyano-H'-methyl-N']-2(4-methyl-imidazolyl)-methylthio-[ethylguanidine]. Additionally, it includes at least one 4-phenyl-tetrahydroisoquinoline antidepressant, preferably the [+] isomer of 4-phenyl-2-methyl-8-amino-1,2,3,4-tetrahydroisoquinoline hydrogen maleate. The composition may also contain a spasmolytic agent, with a preferred example being 2-metoxycarbonyl-4-(beta-piperidino ethyl)-metoxycarbonyl-4-(beta-piperidinoethyl) benzophenone. The ratios of the components are carefully defined, ranging from 2:1 to 60:1 for the antagonist to antidepressant, and from 2.2:1 to 42.5:1 when including the spasmolytic agent.

Another patent involves compounds of the formula (I), which have the ability to inhibit adenylate cyclase. These compounds are characterized by specific substituents, where R₁ and R₂ can be hydroxyl or methoxyl, R₃ is hydrogen or methoxyl, and R₄ is methyl or chloroethyl.
