摘要:
This invention relates to novel opioid peptides for the treatment of pain as well as a method for the preparation thereof and pharmaceutically acceptable compositions comprising these peptides. The invention also relates to methods for controlling pain in patients using compositions of the invention and the use of said compounds in the preparation of formulations effective in pain treatment. The peptides of this invention have a high degree of selectivity for the &mgr;-opioid receptor. The peptides of the present invention are particularly well-suited as analgesic agents acting substantially on peripheral &mgr;-opioid receptors. Because these peptides act peripherally, they substantially avoid producing side effects normally associated with central analgesic action.

A cooling apparatus includes a container configured to contain a coolant within a space. The apparatus further includes a cooling block positioned substantially within the space and having a high heat capacity such that the space not occupied by the cooling block is filled with a coolant to a level at or below the top of the cooling block, and a placement structure having high thermal conductivity positioned on top of the cooling block and outside of the space. A method for cooling an object is also provided, which includes inserting a coolant into a container configured to contain the coolant within a space, and placing the object on a placement structure outside the space. For this method, the placement structure has a high thermal conductivity and is coupled to a cooling block, the cooling block having a high heat capacity and positioned substantially within the space. A two-stage cooling apparatus and method is also described.
摘要:
In a process for preparing pentostatin, the improvement wherein reduction is performed on ketone prior to deprotection, comprising: a) reacting 3-(2-deoxy-3,5-di-O-p-toluoyl-b-D-erythro-pentofuranosyl)-6,7-dihydroimidazol [4,5-d][1,3] diazepin-8 (3H)-one with a ruthenium catalyst formed by the reaction of di-μ-chlorobis[(p-cymene) chlororuthenium (II) and N-(arylsulfonyl)-1,2-diarylethylene diamine in a solvent; b) stopping the reaction in step a) by making the reaction medium alkaline; c) separating the mixture from step b) into combined organic layers and washing the reaction product from the combined organic layers with water, filtering, and evaporating solvent to provide a crude product, wherein the ratio of 8R vs 8S isomeric alcohol >100; d) purifying said crude product by chromatography; e) deprotecting the keto nucleoside in the crude product in methanol/sodium methoxide to obtain pentostatin; and f) purifying by recrystallizing pentostatin from methanol to remove inorganic and isomeric impurities.
