    摘要: The invention relates to methods and compositions for converting taxane amides to paclitaxel or other taxanes. In one alternative embodiment, the present invention comprises; (i) selectively protecting at least one OH group of a taxane amide; (ii) contacting the taxane amide with a transition metal compound to reduce the amide; (iii) contacting the reduced amide with an agent capable of substantially removing the transition metal; (iv) contacting the reduced amide with a hydrolyzing amount of acid to form a taxane amine salt in solution; (v) adding a sufficient amount of solvent to solidify the amine salt; and (vi) converting the taxane amine salt into paclitaxel or other taxanes.

    摘要: The invention provides methods and compositions for selectively acylating a specific hydroxyl group in a molecule of interest containing at least two unprotected secondary hydroxyl groups. Although the methods and compositions of the invention have general applicability, they are particularly useful in the selective acylation of taxane molecules.

    摘要: The present invention relates to a method of isolating and/or purifying hypothalamic inhibitory factor (HIF) from a sample (e.g., tissue fluid) containing HIF. The present invention provides for isolation of large amounts of HIF using diafiltration, solid phase extraction and immunoaffinity techniques. In one embodiment, the invention relates to a method of purifying hypothalamic inhibitory factor from a sample containing hypothalamic inhibitory factor comprising subjecting the sample to diafiltration, solid phase extraction and immunoaffintiy chromatography. In a particular embodiment, the invention relates to subjecting the sample to diafiltration to produce a diafiltrate of HIF; subjecting the diafiltrate to a first solid phase extraction (SPE) to produce a first fraction of HIF; subjecting the first fraction to immunoaffinity chromatography, wherein an antibody which binds to HIF is coupled to an immunoaffinity column, to produce a second fraction of HIF; subjecting the second fraction of HIF to reverse phase HPLC chromatography to produce a third fraction of HIF; and recovering purified HIF from the third fraction.
