- THEOPHYLLINE DERIVATIVES WITH NEMATOCIDAL ACTIVITY, THEIR AGRONOMIC COMPOSITIONS AND RELATIVE USE
-
The present invention relates to theophylline derivatives having general formula (I) agronomic compositions containing said compounds having formula (I) and analogous compounds having formula (XVI) and their use for the control of nematodes in agricultural crops. These compounds advantageously prove to be both effective against parasites and free of phytotoxicity.

- Synthesis and characterization of theophylline-triazole and theophylline-triazole-coumarin based molecular hybrids
-
A series of novel theophylline-triazole and theophylline-coumarin conjugates linked via triazole moiety employing click chemistry has been synthesized and characterized by FT-IR, 1H and 13C NMR, and mass-spectral methods. The reaction was performed regioselectively by using copper sulfate and sodium ascorbate to give 1,2,3-triazoles through Cu(I)-catalyzed azide- alkyne cycloaddition.

- Synthesis and characterization of novel 1,2,3-triazole-linked theophylline and coumarin s-triazines
-
A series of novel s-triazine-1,2,3-triazole-theophylline and s-triazine-1,2,3-triazole-coumarin generation-0 dendrimers has been synthesized and characterized by FT-IR, 1H and 13C NMR, and mass-spectral methods. Some selected compounds have been evaluated for antibacterial and antifungal activity against a variety of strains and for anti-cancer activity against 60 human cancer cell lines.

- New antihistamines: Substituted piperazine and piperidine derivatives as novel H1-antagonists
-
Structural manipulation of polycyclic piperazinyl imide serotonergic agents led to the synthesis of compound 8, 2-[4-[4-[bis(4- fluorophenyl)methyl]-1-piperazinyl]butyl]-4,4a,5,5a,6,6a-hexa-hydro-4,6- ethenocycloprop[f]isoindole-1,3(2H,3aH)-dione, which demonstrated good H1- antagonist activity. Substitution of a xanthinyl moiety for the polycyclic imide group led to the identification of novel xanthinyl-substituted piperazinyl and piperidinyl derivatives with potent antihistamine H1- activity without the undesirable antidopaminergic activity of 8. One compound, 24, 7-[3-[4-(diphenylmethoxy)-1-piperidinyl]propyl]-3,7-dihydro- 1,3-dimethyl-1H-pyrine-2,6-dione (WY-49051), is a potent, orally active H1- antagonist with a long duration of action and a favorable central nervous system profile.
