Abstract:
There are disclosed novel avermectin derivatives wherein the outer oleandrose ring of avermectin or avermectin monosaccharide is homologated by addition of diazomethane to 4"- or 4'-oxo-avermectin to afford the perhydrooxepine derivatives. The homologated avermectins can then be further derivatized to afford additional novel avermectins. The new compounds are potent antiparasitic agents, in particular, the compounds are anthelmintic, insecticidal and acaricidal agents.
Abstract:
There are disclosed synthetic derivatives of the natural product paraherquamide. The synthetic derivatives are prepared by reactions at the parahequamide A, B, E, F and G rings, that is at carbon atoms 14 to 16, the lactam ring and carbon atoms 24 to 26 as well as carbon atoms 5 and 12. The compounds are active antiparasitic agents and compositions for that use are also disclosed.
Abstract:
There are disclosed novel avermectin derivatives wherein the outer oleandrose ring of avermectin or avermectin monosaccharide is homologated by addition of diazomethane to 4"- or 4'-oxo-avermectin to afford the oleandrose 4"- or 4'-spiro-epoxide. The homologated avermectins can then be further derivatized to afford additional novel avermectins. The new compounds are potent antiparasitic agents, in particular, the compounds are anthelmintic, insecticidal and acaricidal agents.
Abstract:
Disclosed are the compounds of the Formula (I) as well as pharmaceutically acceptable salts thereof, which are useful for treating aldosterone-mediated diseases. The processes for preparing compounds of the Formula (I), the use for the therapy and prophylaxis of the abovementioned diseases and for preparing pharmaceuticals for this purpose, and the pharmaceutical compositions which comprise compounds of the formula (I) are disclosed too.
Abstract:
Compounds of Formula (I), including pharmaceutically acceptable salts of the compounds, are CETP inhibitors, and are useful for raising HDL-cholesterol, reducing LDL-cholesterol, and for treating or preventing atherosclerosis. In the compounds of Formula (I), A1 is a cyclic group, and B is a cyclic group which is attached to the heterocyclic ring directly or through a methylene group.
Abstract:
Substituted compounds of the FK-506 Type. These compounds are useful for the same or essentially the same purposes as FK-506 and are applied in the same or a similar manner. These compounds are immunosuppressants and useful for the treatment of autoimmune diseases, infectious diseases and/or the prevention of rejection of foreign organ transplants. Still other uses are described in the disclosure.
Abstract:
Amino O-aryl macrolides of the general structural Formula I: ##STR1## have been prepared from suitable precursors by arylation and amination at C-3"/C-4" of the cyclohexyl ring. These macrolide immunosuppressants are useful in a mammalian host for the treatment of autoimmune diseases, infectious diseases and/or the prevention of rejection of foreign organ transplants. In addition, these macrolide immunosuppressants are useful in the topical treatment of inflammatory and hyperproliferative skin diseases and cutaneous manifestations of immunologically-mediated illnesses. Also, these macrolides are useful in the treatment of reversible obstructive airways disease, particularly asthma; as hair revitalizing agents, especially in the treatment of male pattern alopecia or alopecia senilis; in the reversal of multidrug resistance of tumor cells; in treatment of inflammation of mucosa and blood vessels, gastric ulcers, vascular damage, ischemic bowel disease, inflammatory bowel disease, necrotizing enterocolitis, intestinal lesions associated with thermal burns; in the treatment of cytomegalovirus infection; and in the treatment of idiopathic thrombocytopenic purpura and Basedow's disease.
Abstract:
O-Heteroaryl, O-alkylheteroaryl, O-alkenylheteroaryl and O-alkynylheteroarylmacrolides of the general structural Formula I: ##STR1## have been prepared from suitable precursors by alkylation and/or arylation at C-3" and/or C-4" of the cyclohexyl ring. These macrolide immunosuppressants are useful in a mammalian host for the treatment of autoimmune diseases, infectious diseases, the prevention of rejection of foreign organ transplants and/or related afflictions, diseases and illnesses.
