Abstract: A method is disclosed for preparing hydrazides from hydrazine and an acyl chloride which comprises the steps of (a) preparing a stirred substantially uniform slurry comprising hydrazine and an inert solvent at low temperature; and (b) adding an acyl chloride continuously to said slurry. The method avoids or limits production of undesired bis-hydrazide by-products. The method is used to prepare 3-methyl-3-mercaptobutanoic acid hydrazide, a molecule used to link calicheamicin to a monoclonal antibody.
Abstract: The present invention relates to methods of preparing polymorphic Form A of bazedoxifene acetate and polymorphic Form A prepared by such methods.

Abstract: The invention relates to systems and methods for producing proteins of interest. The invention employs genetically-engineered animal or plant cells that have modified protein folding or processing capacities. In one aspect, the invention features genetically-engineered cells comprising one or more recombinant expression cassettes which encode (1) a protein of interest and (2) a polypeptide that is functional in the unfolded protein response (UPR) pathway of the cells. Co-expression of the polypeptide significantly increases the yield of the protein of interest in the genetically-engineered cells. In one example, the genetically-engineered cells are animal cells, and the co-expressed polypeptide is a component or modulator of an XB1- or ATF6-mediated UPR pathway.
