摘要:
Novel derivatives of 5-thia- and 5-selenopyrimidinone are sound to inhibit the enzyme glycinamide ribonucleotide formyl transferase (GARFT) and amino imidazole carboxamide ribonucleotide formyl transferase (AICARFT). Novel intermediates of these compounds are also disclosed. A novel method of preparing such compounds is also disclosed, as well as methods and compositions for employing the compounds as antiproliferative agents.

The invention generally relates to compounds of the formula I, which are in equilibrium with their 4-hydroxy tautomers, and their pharmaceutically acceptable salts: ##STR1## where n is 0 to 2; A is S, CH.sub.2, O, NH or Se, and when n is 0, A is not CH.sub.2, and when n is 1, A is not CH.sub.2 or NH; X is a substituted or unsubstituted C.sub.1 -C.sub.3 alkyl, C.sub.2 -C.sub.3 alkenyl, C.sub.2 -C.sub.3 alkynyl or amino, or sulfur or oxygen; Ar is a substituted or unsubstituted monocyclic carbocycle or heterocycle, or fused or nonfused polycyclic carbocycle or heterocycle; and R.sub.1 and R.sub.2 are hydrogen or a moiety that forms together with the attached CO.sub.2 a readily hydrolyzable ester group. These compounds and their salts are useful as inhibitors of GARFT or as antiproliferative agents. The invention also pertains to pharmaceutical compositions and methods employing such compounds as GARFT inhibitors or antiproliferative agents. The invention also relates to compounds useful as intermediates for preparing such compounds, and to their synthesis.

The invention relates to a process for preparing a substituted 2-amino-benz[cd]indole of the Formula I: ##STR1## The nitro group of a substituted 1-nitro-8-cyano-naphthalene compound is reduced to an amine group to form a substituted 1-amino-8-cyano-naphthalene compound, which is cyclized to form the substituted 2-amino-benz[cd]indole. The reduction and cyclization may be effected in a one-pot procedure using a reducing agent such as stannous chloride, which generates an acid that cyclizes the reduction product. The syntheses of the 1-nitro-8-cyanonaphthalene compound and its precursors are also described.

摘要:
Quinazoline compounds which demonstrate antiproliferative activity, such as antitumor activity, processes of preparing these compounds, pharmaceutical compositions containing these compounds, and the use of these compounds. These compounds inhibit the growth and proliferation of the cells of higher organisms and microorganisms, such as bacteria, yeasts and fungi. Preferred quinazoline compounds are capable of inhibiting the enzyme thymidylate synthase. Effects derived from the inhibition of the enzyme thymidylate synthase include those discussed above.
