NOVEL BENZOFURAN DERIVATIVES, WHICH CAN BE USED IN PROPHYLAXIS OR TREATMENT OF 5-HT6 RECEPTOR-RELATED DISORDER

The present invention relates to compounds of formula (I): wherein P, R3, W1, and W2 are as described herein, to pharmaceutical compositions comprising the compounds, to processes for their preparation, as well as to the use of the compounds for the preparation of a medicament against 5-HT6 receptor-related disorders.

Syntheses of Trifluoromethyl Heterocycles

Mono and bicyclic heterocycles bearing trifluoromethyl substituent have been synthesized and characterized by spectral studies. 4(5)-Trifluoromethylimidazole (3) is prepared from the reaction of 3,3-dibromo-1,1,1-trifluoroacetone (2) with formaldehyde and ammonia.N-Methylation of 3 by phase transfer reaction gives 1-methyl-4-trifluoromethylimidazole (4). 2-Amino-4-trifluoromethylimidazole (5) is similarly obtained from 3-bromo-1,1,1-trifluoroacetone (1) and thiourea.The reaction of 1 with 2-aminopyridine and 2-aminothiazole gives 2-trifluoromethylimidazopyridine (7) and 6-trifluoromethylimidazothiazole (9) respectively.

Synthesis and antitumor activity of 6 trifluoromethylcyclophosphamide and related compounds

In an attempt to increase the combined toxicity of the metabolic end products [acrolein (4) and phosphoramide mustard (3)] from cyclophosphamide (1), the analog 2 [bis(2 chloroethyl)amino] tetrahydro 6 trifluoromethyl 2H 1,3,2 oxazaphosphorine 2 oxide (2,6 trifluoromethyl cyclophosphamide) was synthesized and its metabolism and antitumor activity studied. Following metabolism of 2 by rat liver microsomes the predicted formation of 4,4,4 trifluorocrotonaldehyde (5) was confirmed by isolation and identification, by mass spectrometry, of its dinitrophenylhydrazone. The therapeutic indices (LD50/ID90) for 2 against the ADJ/PC6 mouse tumor and the Walker 256 tumor in the rat were 28.6 and 7.7, respectively, and were lower than the corresponding values for 1 (91.8 and 33.2, respectively) although the toxicities toward Walker cells in a bioassay system of 1 and 2 dollowing microsomal metabolism were similar. In order to study the toxicities of 4 and 5 released under drug metabolizing conditions independently of the production of a toxic mustard the analogs 18 [2 (diethylamino)tetrahydro 2H 1,3,2 oxazaphosphorine 2 oxide) and 6 [2 (diethylamino)tetrahydro 6 trifluoromethyl 2H 1,3,2 oxazaphosphorine 2 oxide] were also synthesized. The release of 5 from 6 following metabolism was confirmed and shown by use of the bioassay system to be an event of similar toxicity to release of 4 from 18; in vivo, however, 6 (LD50330 mg/kg) was more toxic to mice than 18 (ld50>500 mg/kg).
