摘要:
The present invention relates to an improved and industrially advantageous process for the preparation of (1S, 4S, 5S) -4-bromo-6-oxabicyclo [3.2.1] octan-7-one represented by the following formula (I) which is a key intermediate in the synthesis of edoxaban, a compound that exhibits an inhibitory effect on activated blood coagulation factor X (also referred to as activated factor X or FXa), and is useful as a preventive and/or therapeutic drug for thrombotic diseases. The process includes reacting (1S) -cyclohex-3-ene-1-carboxylic acid of formula (II) with a brominating agent selected from the group consisting of N-bromosuccinimide or 1, 3-dibromo-5, 5-dimethylhydantoin in the presence of a base selected from calcium oxide or calcium hydroxide in a solvent selected from the group comprising of dichloromethane, toluene, tetrahydrofuran, ethy1 acetate, hexanes, cyclopentyl methyl ether (CPME) or a mixture thereof to get ( 1S, 4S, 5S) -4-bromo-6-oxabicyclo [3.2.1] octan-7-one of formula (I).
摘要:
A method of treating ocular hypotension, hypertension, hemorrhage, myocardial ischemia, angina pectoris, coronary contraction, cerebrovascular contraction after subarachnoidal hemorrhage, and asthma which comprises administering to a mammal suffering therefrom a therapeutically effective amount of a thromboxane ligand which is a compound of formula (I), wherein Y is (CH2)x; Z is selected fom the group consisting of (1) and (CR2)x, x is an integer of 1 or 2; R2 is hydrogen or an alkyl radical of from 1 to 4 carbons, A is an alkylene or alkenylene radical having from two to seven carbon atoms, which radical may be substituted with one or more hydroxy, oxo, alkyloxy or alkylcarboxy groups or said alkylene or alkenylene may have one or more enchained oxo or imino radicals; B is a methyl radical or a cycloalkyl radical having from three to seven carbon atoms, or an aryl radical, selected from the group consisting of hydrocarbyl aryl and heteroaryl radicals wherein the heteroatom is selected from the group consisting of nitrogen, oxygen and sulfur atoms, or substituted derivatives of said methyl, cycloalkyl or aryl radicals wherein said substituent is selected from the group consisting of halo, nitro, amino, thiol, hydroxy, alkyloxy and alklycarboxy; and X is selected from the group consisting of cyano, -COOR, -CH2OR, -C(O)N(R2), -CH2N(R2) -CH=N-OH AND -CH2SR1 radicals wherein R is hydrogen or a C1 to C10 alkyl, phenyl or benzyl and E is O or S; or a pharmaceutically acceptable salt thereof.
摘要:
The present invention relates to 7-[carboxyalkyl or alkenyl]-6-[alkyl or alkenyl]-3-oxo-2,4-dioxobicyclo[3.2.1] octanes and derivatives thereof. In particular, hydroxyl, nitro, amino, amido, azido, oxime, thiol, ether and thiol ether derivatives of said carboxy group are contemplated. In particular, 7-[6-carboxy-2-hexenyl]-6-[3-hydroxy-1-octenyl] of 3-oxo-2,4-dioxobicyclo-[3.2.1] octane and derivatives thereof are disclosed. These compounds are useful as ocular hypotensives and as (a) thromboxane mimetics for the prevention of hemorrhaging as follows: during surgery; tooth extraction; hemorrhaging associated with gastro-intestinal diseases and conditions such as hemorrhoids, inflammatory bowel diseases and gastric and peptic ulcers; as a result of stroke; as a complication in retinal diseases resulting in impaired vision and associated with menstruation, childbirth and uterine dysfunction and (b) selective vasoconstrictors for treating systemic hypotension, e.g. in restoring normal blood pressure in hemorrhagic, anaphylactic, or septic shock victims; to provide local anti-inflammatory effects in the eye, skin and nose; to limit plasma exudation in burns, etc. and optimizing blood-born delivery of drugs and diagnostics in encapsulating vehicles.
