摘要:
The present invention provides a synthetic polypeptide which is a random pentapolymer or a salt thereof, comprising alanine, glutamic acid, lysine, tyrosine and phenylalanine, useful for the treatment of autoimmune diseases and, in particular multiple sclerosis (MS). The pentapolymer is a copolymer of alanine, glutamic acid, lysine, tyrosine and phenylalanine, which are randomly polymerized into a polypeptide, thereby forming a random copolymer, or a salt thereof The present invention is based in part on the unexpected finding that the novel pentapolymer shows unexpected oral bioavailability, an advantageous release profile when formulated into a depot drug delivery system and advantageous synergistic activity in autoimmune diseases when combined with an additional therapeutic agent. According to a first aspect, the present invention provides a pentapolymer or a salt thereof, which is a linear random copolymer of alanine, glutamic acid, lysine, tyrosine and phenylalanine.
摘要:
The present invention provides an amorphous form of dronedarone or salt thereof, particularly amorphous dronedarone HCl, pharmaceutical compositions comprising same, methods for its preparation and use thereof in treating cardiac arrhythmias. The amorphous dronedarone HCl has superior aqueous solubility and density characteristics as compared with crystalline dronedarone HCl.
摘要:
The present invention is based on the discovery of a process for preparing pyrimidin- dione compounds, especially alogliptin and its derivatives, which comprises the reaction of a urea derivative of formula (VIII) with a malonic acid or its derivatives to form intermediates of formulae (VII) or (VII-A), which are subsequently converted to a compound of formula (II) upon introduction of a leaving group X. Compound (II) then reacts with an amine to form compound (I), which is optionally converted to its salts of formula (IV).
