Abstract: Sulfonylethyl and thioethyl phosphorodiamidates, their preparation and intermediates in their preparation, formulations containing them, and their pharmaceutical use. The compounds are useful for treating cancer, alone and in combination with other anticancer therapies.

Abstract: The present invention provides methods, apparatus and kits for synthesizing assembled peptides and proteins on a solid phase with sequential ligation of three or more unprotected peptide segments using chemoselective and mild ligation chemistries in aqueous solution. Also provided are methods of monitoring solid phase sequential ligation reactions using MALDI or electrospray ionization mass spectrometry of reaction products.

Abstract: Tripeptide and tetrapeptide thioethers, pharmaceutical compositions containing them, their pharmaceutical use, and their preparation. The compounds are useful in potentiating the cytotoxic effects of chemotherapeutic agents in tumor cells, selectively exerting toxicity in tumor cells, elevating the production of GM progenitors in bone marrow, stimulating the differentiation of bone marrow, mitigating the myelosuppressive effects of chemotherapeutic agents, and modulating hematopoiesis in bone marrow.

Abstract: Novel proteins and protein libraries are disclosed. The proteins possess one or more functional protein modules from different parent protein molecules. The proteins and protein libraries are exemplified by the preparation of cross-over chemokines that contain various combinations of peptide segments derived from RANTES, SDS-1 and vMIP-I and to vMIP-II. The proteins and libraries are extremely pure and can be provided in non-limiting high yields suitable for diagnostic and high-throughput screening assays.

Abstract: A solid-phase method for the synthesis of N-substituted oligomers, such as poly (N-substituted glycines) (referred to herein as poly NSGs) is used to obtain oligomers, such as poly NSGs of potential therapeutic interest which poly NSGs can have a wide variety of side-chain substituents. Each N-substituted glycine monomer is assembled from two "sub-monomers" directly on the solid support. Each cycle of monomer addition consists of two steps: (1) acylation of a secondary amine bound to the support with an acylating agent comprising a leaving group capable of nucleophilic displacement by --NH.sub.2, such as a haloacetic acid, and (2) introduction of the side-chain by nucleophilic displacement of the leaving group, such as halogen (as a solid support-bound .alpha.-haloacetamide) with a sufficient amount of a second sub-monomer comprising an --NH.sub.2 group, such as a primary amine, alkoxyamine, semicarbazide, acyl hydrazide, carbazate or the like.
